Problems solved by technology

At the same time, with the use of high-strength pesticides, the pesticide residues in agricultural products exceed the standard, environmental pollution and farmers' pesticide costs increase, which is not conducive to the sustainable development of agriculture.
[0003] In the prior art, existing pesticides, such as profenofos, etc., have high cost when used alone, which not only limits their popularization and application to a certain extent, but also tends to increase the degree of pest resistance when used alone for a long time

Embodiment 1

[0037] Embodiment 1: ZJ4042 mixed with profenofos

[0038] Table 1 Combined synergistic effect of ZJ4042 and profenofos on Plutella xylostella

[0039] deal with

[0040] Table 2 Combined synergistic effect of ZJ4042 and profenofos on rice leaf roller (Cnaphalocrocis medinalis)

[0041] deal with

[0042] As can be seen from the above Table 1 and Table 2, the composition of profenofos and ZJ4042 is in the scope of 1~50:20~1 (by weight), and the co-toxicity coefficient is all significantly greater than 120, and it is effective for Plutella xylostella and rice Rice leaf rollers all showed synergistic effect.

Embodiment 2

[0043] Example 2 20% profenofos ZJ4042 suspension concentrate

[0044] In terms of weight ratio, according to profenofos 18%, ZJ4042 2%, emulsifier styrylphenol polyoxyethylene polyoxypropylene ether 10%, dispersant SOPA-270 4%, bentonite 2%, xanthan gum 0.11%, 0.4% silicone defoamer, 5% glycerol, and deionized water as the balance, pre-crushed each component, then added to a sand mill for grinding, and prepared after high-shear mixing to obtain 20% glycerol Bromphos ZJ4042 suspension concentrate.

[0045] The prepared 20% profenofos·ZJ4042 suspension concentrate was applied to control Plutella xylostella. 20% profenofos·ZJ4042 suspending agent was sprayed uniformly with water at 10 g / mu in the peak stage of Plutella xylostella larvae, and the control effects were 93.5% and 94.8% after 3 days and 7 days after spraying. Applying pesticides in the same way, the control effect of single agent 40% profenofos emulsifiable concentrate (application rate is 15 grams / mu) and 20% ZJ40...

Embodiment 3

[0046] Example 3 40% profenofos ZJ4042 water dispersible granules

[0047] In terms of weight ratio, according to profenofos 35%, ZJ4042 5%, sodium lauryl sulfate 6%, polysulfate 4%, sodium chloride 8%, polyethylene glycol 3%, and the balance is kaolin The formulation is to dry-grind, granulate, dry and sieve each component to prepare 40% profenofos·ZJ4042 water-dispersible granules.

[0048] The prepared 40% profenofos·ZJ4042 water dispersible granule was applied to control Spodoptera litura. 40% profenofos·ZJ4042 water dispersible granules were sprayed uniformly with water at 10 g / mu at the peak of Spodoptera litura larvae occurrence, and the control effects were 92.1% and 92.7% 3 days and 7 days after the application. Applying pesticides in the same way, the control effect of single agent 40% profenofos emulsifiable concentrate (application rate is 15 grams / mu) and 20% ZJ4042 suspension concentrate (application rate is 10 grams / mu) in 3 days after the drug is respectively ...

Abstract

The invention discloses insecticide composition containing profenofos and ZJ4042. The insecticide composition comprises two active ingredients: the first active ingredient is profenofos, the second active ingredient is 3-chlorine-N1-(2-methyl-4-heptafluoroisopropyl phenyl)-N2-(1-methyl-1-cyanoethyl) phthalic anhydride, and the mass ratio of the two active ingredients is (1-50): (20-1). The insecticide and sterilization composition is suitable for controlling lepidoptera insects.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to an insecticidal composition. Background technique [0002] The problem of resistance to agricultural pests is a global problem. With the continuation of chemical control of pests, the increase in the use of pesticides, and the unscientific use of pesticides, the resistance of pests is becoming more and more serious, and the types of resistant pests are increasing. In particular, Lepidoptera pests, which seriously damage agricultural production, have a high degree of resistance and relatively fast development of resistance. At the same time, with the use of high-strength pesticides, pesticide residues in agricultural products exceed the standard, environmental pollution and farmers' pesticide costs increase, which is not conducive to the sustainable development of agriculture. [0003] In the prior art, existing pesticides, such as profenofos, etc., have high cost when used alone, whic...
