FOREWORD
Intensive agricultural practices relying heavily on chemical pesticides are a major cause of wide spread ecological
imbalances resulting in serious problems of insecticide resistance, pest resurgence and pesticide residues. There is
a growing awareness world over on the need for promoting environmentally sustainable agriculture practices.
Integrated Pest Management (IPM) is a globally accepted strategy for promoting sustainable agriculture. During
last century, IPM relied substantially on economic threshold level and chemical pesticides driven approaches.
However, since the late 1990s there is conscious shift to more ecologically sustainable Agro-Eco System Analysis
(AESA) based IPM strategies. The AESA based IPM focuses on the relationship among various components of an agro-
ecosystem with special focus on pest-defender dynamics, innate abilities of plant to compensate for the damages
caused by the pests and the influence of abiotic factors on pest buildup. In addition, Ecological Engineering for pest
management - a new paradigm to enhance the natural enemies of pests in an agro-ecosystem is being considered
as an important strategy. The ecological approach stresses the need for relying on bio intensive strategies prior to
use of chemical pesticides.
Sincere efforts have been made by resource personnel to incorporate ecologically based principles and field
proven technologies for guidance of the extension officers to educate, motivate and guide the farmers to adopt
AESA based IPM strategies, which are environmentally sustainable. I hope that the AESA based IPM packages
will be relied upon by various stakeholders relating to Central and State government functionaries involved in
extension and Scientists of SAUs and ICAR institutions in their endeavour to promote environmentally sustainable
agriculture practices.
FOREWORD
IPM as a holistic approach of crop protection based on the integration of multiple strategies viz., cultural, physical,
mechanical, biological, botanical and chemical. Over the years IPM underwent several changes, shifting its focus
from damage boundary, economic injury to economic threshold. Currently most stake holders rely upon economic
threshold levels (ETL) and tend to apply chemical pesticides at the first instance in the event of a pest attack,
through Government of India has advocated need based and judicious application of chemicals. This approach
is likely to cause adverse effects on agro-ecosystems and increase the cost of agricultural production due to
problems of pest resurgence, insecticide resistance and sustainability.
During the late 90s FAO started advocating Agro-Ecosystem Analysis (AESA) based IPM. Experience in
different countries have sine show that AESA, which takes into account ecological principles and relies on the
balance that is maintained by biotic factors in an ecosystem has also resulted in reduction in cost of production
and increase in yields. AESA based IPM also takes into account the need for active participation of farmers and
promotes experiential learning and discovery based decision making by farmers. AESA based IPM in conjunction
with ecological engineering for pest management promotes bio-intensive strategies as against current chemical
intensive approaches, while retaining the option to apply chemical pesticides judiciously as a measure of last
resort.
The resource persons of NIPHM and DPPQ&S have made sincere efforts in revising IPM packages
for different crops by incorporating agro-ecosystem analysis, ecological engineering, pesticide application
techniques and other IPM options with the active cooperation of crop based plant protection scientists working
in state Agricultural Universities and ICAR institutions. I hope this IPM package will serve as a ready reference for
extension functionaries of Central / State Governments, NGOs and progressive farmers in adopting sustainable
plant protection strategies by minimizing the dependence on chemical pesticides.
PREFACE
Need for environmentally sustainable agricultural practices is recognised worldwide in view of the wide spread
ecological imbalances caused by highly intensive agricultural systems. In order to address the adverse impacts
of chemical pesticides on agro-ecosystems, Integrated Pest Management has evolved further from ETL based
approach to Agro-ecosystem Analysis based Integrated Pest Management (IPM).
In AESA based IPM the whole agro-ecosystem, plant health at different stages, built-in-compensation
abilities of the plant, pest and defender population dynamics, soil conditions, climatic factors and farmers’
past experience are considered. In AESA, informed decisions are taken by farmers after field observation , AESA
chart preparation followed by group discussion and decision making. Insect zoo is created to enable the farmer
understand predation of pests by Natural Enemies. AESA based PHM also results in reduction of chemical pesticide
usage and conserves the agro-ecosystems.
Ecological Engineering for Pest Management, a new paradigm, is gaining acceptance as a strategy for
promoting Biointensive Integrated Pest Management. Ecological Engineering for Pest Management relies on
cultural practices to effect habitat manipulation and enhance biological control. The strategies focus on pest
management both below ground and above ground. There is growing need to integrate AESA based IPM and
principles of ecological engineering for pest management.
There is a rising public concern about the potential adverse effects of chemical pesticides on the human
health, environment and biodiversity. The intensity of these negative externalities, through cannot be eliminated
altogether, can be minimized through development, dissemination and promotion of sustainable biointensive
approaches.
Directorate of Plant Protection Quarantine and Storage (DPPQS), has developed IPM package of practices
during 2001 and 2002. These packages are currently providing guidance to the Extension Officers in transferring
IPM strategies to farmers. These IPM package of practices, have been revised incorporating the principles of AESA
based IPM in detail and also the concept of Ecological Engineering for Pest Management. It is hoped that the
suggested practices, which aim at enhancing biodiversity, biointensive strategies for pest management and
promotion of plant health, will enable the farmers to take informed decisions based on experiential learning and
it will also result in use of chemical pesticides only as a last resort & in a safe and judicious manner.

AESA based IPM – Tomato
The plant is herbaceous, annual have a basal or terminal group of leaves. The leaves are generally alternate
or alternate to opposed (that is, alternate at the base of the plant and opposed towards the inflorescence). The
leaves can be herbaceous, leathery and are generally petiolate or subsessile, rarely sessile. The leaves have
reticulated venation and lack a basal meristem. The flowers are hermaphrodites. The flowers can be solitary or
grouped into terminal, cymose, or axillary inflorescences. The flowers are usually actinomorphic. The flowers have
a differentiated perianth with a calyx and corolla (with five sepals and five petals, respectively) an androecium
with five stamens and two carpels forming a gynoecium with a superior ovary. The stamens are epipetalous and
are typically present in multiples of four or five, most commonly four or eight. They usually have a hypogynous
disk. The major tomato producing states are Bihar, Karnataka, Uttar Pradesh, Orissa, Andhra Pradesh, Maharashtra,
Madhya Pradesh and West Bengal. Tomato is rich source of vitamins A, C, potassium, minerals and fibers. Tomatoes
are used in the preparation of soup, salad, pickles, ketchup, puree, sauces and also consumed as a vegetable in
many other ways.

AESA based IPM – Tomato
Observe the field regularly (climatic factors, soil and biotic factors):
Farmers should:
• Monitor the field situations at least once a week (soil, water, plants, pests, natural enemies, weather factors
etc.)
• Make decisions based on the field situation and Pest: Defender ratio (P: D ratio)
• Take direct action when needed (e.g. collect egg masses, remove infested plants etc.)

AESA based IPM – Tomato
Insect zoo:
In field various types of insects are present. Some are beneficial and some may be harmful. Generally farmers
are not aware about it. Predators (friends of the farmers) which feed on pests are not easy to observe in crop
field. Insect zoo concept can be helpful to enhance farmers’ skill to identify beneficial and harmful insects. In this
method, unfamiliar/unknown predators are collected in plastic containers with brush from the field and brought
to a place for study. Each predator is placed inside a plastic bottle together with parts of the plant and some known
insect pests. Insects in the bottle are observed for certain time and determined whether the test insect is a pest
(feeds on plant) or a predator (feeds on other insects).

AESA based IPM – Tomato
Decision making:
Farmers become experts in crop management:
Farmers have to make timely decisions about the management of their crops. AESA farmers have learned to make
these decisions based on observations and analysis viz. abiotic and biotic factors of the crop ecosystem. The past
experience of the farmers should also be considered for decision making. However, as field conditions continue to
change and new technologies become available, farmers need to continue improving their skills and knowledge.
• Farmers are capable of improving farming practices by experimentation
• Farmers can share their knowledge with other farmers
6
AESA based IPM – Tomato
AESA methodology:
• Go to the field in groups (about 5 farmers per group). Walk across the field and choose 20 plants/ acre
randomly. Observe keenly each of these plants and record your observations:
• Plant: Observe the plant height, number of branches, crop stage, deficiency symptoms etc.
• Insect pests: Observe and count insect pests at different places on the plant.
• Defenders (natural enemies): Observe and count parasitoids and predators.
• Diseases: Observe leaves and stems and identify any visible disease symptoms and severity.
• Rats: Count number of plants affected by rats.
• Weeds: Observe weeds in the field and their intensity.
• Water: Observe the water situation of the field.
• Weather: Observe the weather conditions.
• While walking in the field, manually collect insects in plastic bags. Use a sweep net to collect additional
insects. Collect plant parts with disease symptoms.
• Find a shady place to sit as a group in a small circle for drawing and discussion.
• If needed, kill the insects with some chloroform (if available) on a piece of cotton.
• Each group will first identify the pests, defenders and diseases collected.
• Each group will then analyze the field situation in detail and present their observations and analysis in a
drawing (the AESA drawing).
• Each drawing will show a plant representing the field situation. The weather condition, water level, disease
symptoms, etc. will be shown in the drawing. Pest insects will be drawn on one side. Defenders (beneficial
insects) will be drawn on another side. Write the number next to each insect. Indicate the plant part
where the pests and defenders were found. Try to show the interaction between pests and defenders.
• Each group will discuss the situation and make a crop management recommendation.
• The small groups then join each other and a member of each group will now present their analysis in front
of all participants.
• The facilitator will facilitate the discussion by asking guiding questions and makes sure that all participants
(also shy or illiterate persons) are actively involved in this process.
• Formulate a common conclusion. The whole group should support the decision on what field management
is required in the AESA plot.
• Make sure that the required activities (based on the decision) will be carried out.
• Keep the drawing for comparison purpose in the following weeks.
Data recording:
Farmers should record data in a notebook and drawing on a chart
• Keeping records of what has happened help us making an analysis and draw conclusions
Data to be recorded:
• Check the plant growth weekly
• Crop situation (e.g. for AESA): Plant health; pests, diseases, weeds; natural enemies; soil condition;
irrigation; weather conditions
• Input costs: Seeds; fertilizer; pesticides; labour
• Harvest: Yield (Kg/acre); price of produce (Rs./Kg); Price of produce (Rs./Kg)
Some questions that can be used during the discussion:
• Summarize the present situation of the field.
• What crop management aspect is most important at this moment?
• Is there a big change in crop situation compared to last visit? What kind of change?
• Is there any serious pest or disease outbreak?
• What is the situation of the beneficial insects?
• Is there a balance in the field between pests and defenders?
• Were you able to identify all pests and diseases?
• Do you think the crop is healthy?

B. Field scouting:
AESA requires skill. So only the trained farmers can undertake this exercise. However, other farmers also can do
field scouting in their own fields at regular intervals to monitor the major pest situation.
Surveillance on pest occurrence in the main field should commence soon after crop establishment and at
weekly intervals thereafter. In field, select five spots randomly. Select five random plants at each spot for recording
counts of insects as per procedure finalized for individual insects.
For diseases:
Whenever scouting, be aware that symptoms of plant disease problems may be caused by any biotic factors such
as fungal, bacterial, viral pathogens or abiotic factors such as weather, fertilizers, nutrient deficiencies, pesticides
and abiotic soil problems. In many cases, the cause of the symptom is not obvious. Close examination, and
laboratory culture and analysis are required for proper diagnosis of the causal agent of disease. Generally fungal
diseases cause the obvious symptoms with irregular growth, pattern & colour (except viruses), however abiotic
problems cause regular, uniform symptoms. Pathogen presence (signs) on the symptoms can also be observed
like fungal growth, bacterial ooze etc. Specific and characteristic symptoms of the important plant diseases are
given in description of diseases section.
Root sampling: Always check plants that appear unhealthy. If there are no obvious symptoms on plants, examine
plants randomly and look for lesions or rots on roots and stems. Observe the signs of the causal organism (fungal
growth or ooze). It is often necessary to wash the roots with water to examine them properly. If the roots are well
developed, cut them to examine the roots for internal infections (discolouration & signs). Count the total number
of roots damaged/infested/infected due to rot should be counted and incidence should be recorded.
Leaf sampling: Examine all leaves of each plant for lesions. Leaf diseases cause most damage during the seedling
and flowering stages of plant growth. Observe for the symptoms and signs on the infected plant parts. Determine
the percent area of leaf infection by counting the number of leaves (leaf area diameter)/plant infected due to
disease and incidence should be recorded.
Stem, flower and fruit sampling: Carefully examine the stem, flower, and fruit of plants for symptoms and
signs of fungal or bacterial diseases. The stem, flower, and fruit should be split or taken apart and examined for
discoloration caused by fungi and bacteria. Count the number of stems, flowers and fruits infected due to disease
and percent disease incidence should be recorded.

E. Light traps:
Set up light trap @ 1 trap/acre 15 cm above the crop canopy for monitoring and mass trapping insects. Light traps
with exit option for natural enemies of smaller size should be installed and operate around the dusk time (6 pm
to 10 pm).
F. Nematode extraction:
Collect 100 to 300 cm3 (200-300 g) representative soil sample. Mix soil sample and pass through a coarse sieve
to remove rocks, roots, etc. Take a 600 cc subsample of soil, pack lightly into a beaker uniformly. Place soil in one
of the buckets or pans half filled with water. Mix soil and water by stirring with paddle; allow to stand until water
almost stops swirling. Pour all but heavy sediment through 20-mesh sieve into second bucket; discard residue
in first bucket; discard material caught on sieve. Stir material in second bucket; allow to stand until water almost
stops swirling. Pour all but heavy sediment through 200-mesh sieve into first bucket; discard residue in second
bucket. Backwash material caught on 200-mesh sieve (which includes large nematodes) into 250-ml beaker. Stir
material in first bucket; allow to stand until water almost stops swirling. Pour all but heavy sediment through
325-mesh sieve into second bucket; discard residue in first bucket. Backwash material caught on 325-mesh sieve
(which includes small to mid-sized nematodes and silty material) into 250-ml beaker. More than 90% of the live
nematodes are recovered in the first 5-8 mm of water drawn from the rubber tubing and the sample is placed in a
shallow dish for examination.

Powdery mildew:
• Growing resistant varieties
• Adopt early planting, sprinkler irrigation
• Immediately remove and destroy diseased leaves to help prevent the disease from spreading.
• Proper plant spacing of about 3 feet apart to allow for proper air circulation, which helps the foliage dry
faster.
• Periodic clipping of lower leaves and mulching
• Organic mulch added around the plants will protect roots while preventing fungal spores from splashing
onto the plant.
Day 1: Close all the burrows in the fields, field bunds, canal bunds and
surrounding barren lands etc.
Day 4: Observe the re-opened burrows and treat the burrow with zinc
phosphide poison bait (96 parts of broken tomato + 2 parts of edible oil +
2 parts of zinc phosphide) @ 10g/ burrow. Collect the dead rats, if found any
outside and bury them.

Blossom-end rot:
Blossom-end rot (BER) is caused by a localized Ca deficiency in the
developing fruit. It begins with light tan, water-soaked areas that can
then enlarge and turn black and leathery in appearance. Most often the
problem occurs at the blossom end of the fruit. Factors like low soil Ca,
high N rates, using ammoniacal sources of N, high concentrations of
soluble K and Mg in the soil, high salinity, low humidity, inadequate or
excess soil moisture, damage to root system by nematodes, diseases
etc. increases the BER problem.
Correction measure: Soil applications of Ca materials, proper
Fruit showing symptoms of BER, top
fertilization and good water management can prevent the problem. left fruit showing mild BER, others
showing severe
Cat-face:
Cat-facing is a generic term used to describe a tomato fruit that has a gross deformity and is usually not marketable.
The defect is usually located on the blossom end of the fruit. The deformity is starts occurring during the formation
of the flower that results in the fruit not developing normally. Low temperatures, herbicide drifts, heavy thrips
feeding and little leaf disease are some of the causes of cat-faced fruits.
Correction measure: Varieties should be selected that historically have had little problem with cat-facing, avoiding
spray drift, water logging etc. can reduce the problem.
Fruit showing cat-facing into fruit Cat-faced fruit with hole on blossom end
Cracking:
Cracking occurs when the internal expansion is faster than the expansion of the epidermis and the epidermis
splits. Varieties differ greatly in their susceptibility to cracking.
Correction measure: Control is through selecting tolerant varieties
or by reducing fluctuations in soil moisture. Cracking may also be
reduced by maintaining good foliage cover, since exposed fruit are
more susceptible.

Puffiness:
When this problem is slight, it may be impossible to detect puffiness until fruit are cut. When fruit are cut, open
cavities are observed between the seed gel area and the outer wall. Fruits are also very light in relation to size.
This problem is caused by any factor that affects fruit set, including inadequate pollination, fertilization, or seed
development. Most common causes are too low or high temperatures during fruit set. Other factors such as high
N, low light, or rainy conditions can also cause seed set problems.
Correction measure: Application of balanced Nitrogen doses may reduce the problem.
Note flattened areas on sidewalls of fruit caused by puffiness Fruit severely affected by puffiness, note large open areas
Zebra Stripe:
Zebra stripe can be characterized as a series of dark green spots arranged in a
line from the stem end to the bloom end. At times it seems the spots coalesce
together and form elongated markings. Many times the dark green areas
will disappear when fruit ripens. This problem seems to be variety related. It
is probably a genetic defect that only develops under certain environmental
conditions. Zebra stripe may be linked to pox and fleck.
Zippering:
Zippering is described as a fruit having thin scars that extend partially or fully
from the stem scar area to the blossom end. The longitudinal scar has small
transverse scars along it. At times there may be open holes in the locules in
addition to the zipper scar. Usually an anther that is attached to the newly
forming fruit causes the zipper scar. Some people feel that a zipper is formed
when the “blooms” stick to the fruit and do not shed properly but this may not
be a cause.
Correction measure: The only control is to select varieties that are not prone
to zippering.

3) Tobacco caterpillar:
Biology:
It is found throughout the tropical and subtropical parts of the world, wide spread in India. Besides tobacco, it
feeds on cotton, castor, groundnut, tomato, cabbage and various other cruciferous crops.
Egg: Female lays about 300 eggs in clusters. The eggs are covered over by brown hairs and they hatch in about
3-5 days.
Larva: Caterpillar measures 35-40 mm in length, when full grown. It is velvety, black with yellowish – green
dorsal stripes and lateral white bands with incomplete ring – like dark band on anterior and posterior end of the
body. It passes through 6 instars. Larval stage lasts 15-30 days
Pupa: Pupation takes place inside the soil. Pupal stage lasts 7-15 days.
Adult: Moth is medium sized and stout bodied with forewings pale grey to dark brown in colour having wavy
white crisscross markings. Hind wings are whitish with brown patches along the margin of wing. Pest breeds
throughout the year. Moths are active at night. Adults live for 7-10 days. Total life cycle takes 32-60 days. There
are eight generations in a year.
Life cycle:
Damage symptoms:
• In early stages, the caterpillars are gregarious and
scrape the chlorophyll content of leaf lamina giving
it a papery white appearance. Later they become
voracious feeders making irregular holes on the
leaves.
• Irregular holes on leaves initially and later
skeletonization leaving only veins and petioles
• Heavy defoliation.
• Bored fruits with irregular holes

6) Root-knot nematode:
Biology:
• Most species of plant parasitic nematodes have a relatively simple life cycle consisting of the egg, four larval
stages and the adult male and female. They are microscopic in size.
• Development of the first stage larvae occurs within the egg where the first moult occurs. Second stage
larvae hatch from eg gs to find and infect plant roots or in some cases foliar tissues.
• Under suitable environmental conditions, the eggs hatch and new larvae emerge to complete the life cycle
within 4 to 8 weeks depending on temperature.
• Nematode development is generally most rapid within an optimal soil temperature range of 70 to 80°F.
Life cycle:
Life stages are microscopic in size
Damage symptoms:
• Infected plants in patches in the field
• Formation of galls on host root system is
the primary symptom
• Roots branch profusely starting from
the gall tissue causing a ‘beard root’
symptom
• Infected roots become knobby and
knotty
• Plants wilt during the hot part of day,
especially under dry conditions and are
often stunted

• In severely infected plants the root system is reduced and the rootlets are almost completely absent. The
roots are seriously hampered in their function of uptake and transport of water and nutrients
• Seedlings infected in nursery do not normally survive transplanting and those surviving have reduced
flowering and fruit production
• Nematode infection predisposes plants to fungal and bacterial root pathogens

5) Early blight:
Disease symptoms:
• This is a common disease of tomato occurring on the foliage at any stage of the growth.
• The fungus attacks the foliage causing characteristic leaf spots and blight. Early blight is first observed
on the plants as small, black lesions mostly on the older foliage.
• Spots enlarge, and by the time they are one-fourth inch in diameter or larger, concentric rings in a bull’s
eye pattern can be seen in the center of the diseased area.
• Tissue surrounding the spots may turn yellow. If high temperature and humidity occur at this time,
much of the foliage is killed.
• Lesions on the stems are similar to those on leaves, sometimes girdling the plant if they occur near the
soil line.
• Transplants showing infection by the late blight fungus often die when set in the field. The fungus also
infects the fruit, generally through the calyx or stem attachment.
• Lesions attain considerable size, usually involving nearly the entire fruit; concentric rings are also
present on the fruit.

8) Leaf curl:
Disease symptoms:
• Leaf curl disease is characterized by severe stunting of the
plants with downward rolling and crinkling of the leaves.
The newly emerging leaves exhibit slight yellow colouration
and later they also show curling symptoms.
• Older leaves become leathery and brittle. The nodes and
internodes are significantly reduced in size.
• The infected plants look pale and produce more lateral
branches giving a bushy appearance. The infected plants
remain stunted.

9) Mosaic:
Disease symptoms:
• The disease is characterized by light and dark green mottling on the leaves often accompanied by
wilting of young leaves in sunny days when plants first become infected.
• The leaflets of affected leaves are usually distorted, puckered and smaller than normal. Sometimes the
leaflets become indented resulting in “fern leaf” symptoms.
• The affected plant appears stunted, pale green and spindly.
