Botanical insecticides are extracts from plants that are used to control insects. They work by containing insect toxins or deterring insects from feeding. Some common botanical insecticides include nicotine from tobacco, pyrethrum from chrysanthemums, and neem oil. These products tend to act quickly on target pests but do not persist in the environment and degrade rapidly. Their use depends on factors like raw material availability, extraction methods, and weather conditions.

These insecticides are naturally occurring chemicals
extracted from seeds, flowers, leaves, stem and roots
are termed as Botanical Insecticides. These products are used to kill or repel insects that consists of dried, ground plant material, crude plant extracts, or chemicals isolated from plants. The recorded use of plant material or plant extracts for insect control dates back at least 200 years. Insect Toxins derived from certain plants. Quick action On target pests. Board Spectrum action (Non-selective). Do not persist in environment. Factors affecting use of Botanical Insecticides Raw material availability Solvent types,plant species and part of plant Rapid degradation State registration Market opportunities for Botanical pesticides Weather conditions The Botanical Insecticides are divided into two generations:
The 1st generation included:
Nicotine, Rotenone, Ryania, Pyrethrum.
The 2nd generation included:
Synthetic pyrethroids and Neem products
Potential new Botanicals:
Annonaceous Acetogenins, Sucrose Ester Characteristics- Sources-Tobacco Plant (from leaves), Contact and fumigants action Mode of Action- Nicotine sulphate acts upon the central nervous system of the insects.It has both contact as well as fumigation action. Uses- Nicotine sulphate 40% is used to kill aphids, bugs,worms,leafhoppers and similar sucking insects which attack and destroy fruit,vegetables,crops and even flowers.It is also effective against lice, mites and ticks which are a menace to livestock. Characteristics- Sources-Chrysanthemum cinerariaefolium (from flower) Mode of Action- Pyrethrum is a naturlly derived, professional-grade pesticide which attacks the nervous system of a wide spectrum of pest insects Uses- Used against aphids, cucumber beetles, caaterpillars and small sized and immature insects. Characteristics- Sources- full-grown neem tree yields 50kg fruit annually and 350kg of leaves. Mode of Action- Neem oil is not a contact poison. It does not kill insect pests directly.It is systemic in action, mainly affecting the feeding as well as growth and development of insects. Nothing will happen immediately even if you spray the oil on them, so people often come to the conclusion that neem oil is ineffective and just all type. Uses- Used against immature insects as foliar spray Often these plants also have other uses like household insect or are plants with medicinal applications. Some of these products may be used shortly before harvesting. Many of these products act very quickly inhibiting insect feeding Since most of these products have a stomach action and are rapidly decomposed they may be more selective to insect pests. Most of these compounds are not phytotoxic.. Most of these products are not truly pesticides are not truly pesticides since many are merely insect deterrents and their effect is slow. They are rapidly degraded by UV light so that their residual action is short. They are not necessarily available season long. There are no legal registrations establishing their use. Not all recommendations followed by growers have been scientifically verified.
