30 various crop such as dish, Rhizoma Zingiberis Recens, Herba Alii fistulosi, Bulbus Allii, Fructus Musae.Root-knot nematode is common are, the root knot that plant root forms enlargement is often resulted in, no
Energy normal absorption nutrient, causes plant withered and yellow or dead, while some funguses and bacterial disease can also be propagated.
Trifluoro miaow pyridine amide (fluazaindolizine), non-stifling property nematicide, to soybean cyst nematode Heterodera glycines, kidney shape line
Worm, pratylenchus, root-knot nematode, minute hand nematicide etc. are respectively provided with fabulous biological activity.
Paecilomyces lilacinus (Paecilomyces lilacinus Samson) belong to endoparasitism funguses, and this bacterium is extensively divided
It is distributed in all over the world, there is effect height, Ji Zhuguang, easily cultivate, especially effect is tall and erect in terms of control plant pathogeny line insect
Write, such as to Meloidogyne incognita, cyst roundworm, white ball cyst roundworm, puncture nematicide, golden nematicide, golden nematode and treasure
Pearl nematicide has stronger parasitic ability, can infect the ovum of nematicide, and then reaches the purpose of parasite killing, and the pathogenic fungi has pathogenic
By force, effect duration is longer.
The mixture of different pesticide species, is the agriculture disease-resistant, worm of preventing and treating, the common methods of crop smothering.Screened by formulation of pesticide, screening
Go out rational formula, actual prevention effect can be effectively improved, reduce dosage, reduces cost delays the generation of disease drug resistance,
It is disease, worm, the important means of crop smothering comprehensive control.Present inventor is by trifluoro miaow pyridine amide and Paecilomyces lilacinus formula
Trifluoro miaow pyridine amide and 5 Bioflor 250mg capsules spores/gram Paecilomyces lilacinus are carried out mixture by the further investigation of screening, discovery, are mixed in certain
With having obvious potentiation in the range of ratio to nematicide, can effectively preventing crops nematicide, reduce dosage, meet
The demand of " pesticide zero growth rate ".After further research, complete the present invention.At present, there is no with regard to trifluoro miaow pyridine amide with it is light
The relevant report of purple Paecilomyces varioti compounding.

2nd, Assays Example
Test name：Trifluoro miaow pyridine amide and 5 Bioflor 250mg capsules spores/gram indoor biometricses of the Paecilomyces lilacinus mixture to Fructus Cucumidis sativi root-knot nematode
Test
Test method：The cucumber root for producing a large amount of root knots is taken, tap water is gently rinsed well, with dissecting needle gently picking old complaint
On milky egg capsule, be put in the little culture dish of diameter 6cm, add a small amount of sterilized water, hatch 3-4d in 25 DEG C of calorstats,
2 instar larvaes are collected, and adds sterilized water to be configured to finite concentration（500/milliliter or so）Suspension it is standby.
Arrange variable concentrations gradient to process, with sterilized water as blank, take 96 porocyte culture plates, add per hole and prepare
Variable concentrations medicament 150mL, add isopyknic nematicide suspension, moisturizing culture under the conditions of 25 DEG C, respectively place
Different time after reason checks the amount of survival of 2 instar of Meloidogyne incognita and The dead quantity, nematicide in stiff motionless for dead worm,
Line is filled in bending wriggling state for worm living.Calculate mortality rate and corrected mortality.
According to survey data, the corrected mortality of each process is calculated.And the abundant methods of Sun Yun are adopted with reference to NY/T1154.1-2006
Calculate the co-toxicity coefficient of mixture（CTC values）.If control mortality rate ＜ 5%, does not correct；Control mortality rate is carried out between 5-20%
Correction；Control mortality rate ＞ 20%, test need to be reformed.With drug concentration（mg/L）Logarithm value be independent variable x, to correct death
The niqueMin of rate is dependent variable y, sets up virulence regression equation respectively, using DPS computed in software single dose and each proportioning mixture
LC50,95% confidence limit and mixture co-toxicity coefficient, compare potentiation situation.Act on according to NY/T11547.7-2006 insecticide combinations
The criteria for classifying：Co-toxicity coefficient（CTC values）>=120 show as potentiation；Co-toxicity coefficient（CTC values）≤ 80 is antagonism；80
＜ co-toxicity coefficients（CTC values）＜ 120 is summation action.Trifluoro miaow pyridine amide and 5 Bioflor 250mg capsules spores/gram Paecilomyces lilacinus are to Radix Cucumidis sativi
The synergy result of tie lines worm is as shown in table 1.
As can be seen from Table 1, trifluoro miaow pyridine amide and 5 Bioflor 250mg capsules spores/gram Paecilomyces lilacinus are 1:30-30:In the range of 1
Preventing and treating to Fructus Cucumidis sativi root-knot nematode shows synergistic function, wherein, when both proportionings are 1:10-10:It is in the range of 1, right
, more than 200, synergistic function is more notable for the preventing and treating co-toxicity coefficient of Cucumber root-knot nematode disease.
3rd, field control effectiveness test
In order to preferably verify the field practical application effect of composition pesticide of the present invention, using embodiment of the present invention 1-3 and right
The composition pesticide of ratio 1-6 carries out preventing and treating Cucumber root-knot nematode disease field control effectiveness test, often processes in triplicate, per cell one
Individual repetition, is arranged using going at random to rent, plot area 20m2.It is shallow mixed in preplanting treatment dispenser is broadcast, it is random to sow.After medicine
30th, 60 days investigation root-knot nematode quantity.Using diagonal sampling method, per samples 3 plants, investigates disease index and sickness rate root knot
The Recording criteria of eelworm harm, raw many major general's state of an illness according to root knot and is divided into Pyatyi：
0 grade without root knot；
1 grade of root knot accounts for the 1-25% of full root system；
2 grades of root knots account for the 26-50% of full root system；
3 grades of root knots account for the 51-75% of full root system
4 grades of root knots account for the 76-100% of full root system
According to formula（5）And formula（6）Calculate the prevention effect of Fructus Cucumidis sativi root-knot nematode：
Table of field test results is bright, and the compositionss of trifluoro miaow pyridine amide and 5 Bioflor 250mg capsules spores/gram Paecilomyces lilacinus are to Radix Cucumidis sativi tie lines
The preventing and treating of worm shows preferable lasting effect and quick-acting, and the composition pesticide of example of formulations 1-3 is in effective ingredient dosage
When being 1.5 Kg/ mus, preventive effect is above trifluoro miaow pyridine amide and 5 Bioflor 250mg capsules spores/gram Paecilomyces lilacinus single dose, illustrates the present invention
Composition pesticide can prevent and treat crops nematicide well, reduce dosage, reduces cost delays the drug-fast generation of nematicide,
Reduce the pollution to environment.To sum up, composition pesticide of the invention is worth the popularization and application in production.
