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 etofenprox, etc., have relatively high drug costs 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

[0038] Embodiment 1: ZJ4042 and etofenprox composition

[0039] Table 1. Combined synergistic effect of ZJ4042 and etofenprox against cabbage beet armyworm (Spodoptera exigua)

[0040] formula

[0041] Table 2. Combined synergistic effect of ZJ4042 and etofenprox against Cnaphalocrocis medinalis

[0042] formula

[0043] As can be seen from Table 1 and Table 2, the composition of etofenprox and ZJ4042, within the scope of 1~50:20~1 (by weight), has a co-toxicity coefficient greater than 120, which is effective against cabbage stem borer and rice Rice leaf rollers all showed synergistic effect.

Embodiment 2

[0044] Embodiment 2 (20% etofenprox ZJ4042 suspension concentrate)

[0045] According to Etoproxil 18%, ZJ40422%, emulsifier 1601# (styrylphenol polyoxyethylene polyoxypropylene ether) 10%, dispersant SOPA-270 4%, bentonite 2%, xanthan gum 0.1%, organic Silicone defoamer 0.4%, glycerin 5%, the balance is deionized water, the ingredients are pre-crushed, then added to a sand mill for grinding, and prepared after high-shear mixing to prepare 20% ether chrysanthemum Ester · ZJ4042 suspending agent.

[0046] The prepared 20% etofenprox-ZJ4042 suspension concentrate was applied to control rice stem borer. 20% Etoproxil·ZJ4042 suspension concentrate was mixed with water and sprayed evenly at 10 g / mu in the peak stage of rice stem borer larvae, and the control effects were 90.2% and 91.2% after 3 days and 7 days after spraying. Applying pesticides in the same way, the control effects of single agent 15% etofenprox suspension concentrate (application rate is 15 grams / mu) and 20% ZJ4...

Embodiment 3

[0047] Example 3 (40% etofenprox ZJ4042 water dispersible granules)

[0048] According to the formula of Etoproxil 35%, ZJ40425%, sodium lauryl sulfate 6%, polysulfate 4%, sodium chloride 8%, polyethylene glycol 3%, and the balance is kaolin, each component is Dry pulverization, granulation, drying, and sieving were used to prepare 40% etofenproxil·ZJ4042 water-dispersible granules.

[0049] The prepared 40% etofenprox-ZJ4042 water dispersible granule was applied to control Spodoptera litura. 40% Etoproxil·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 90.6% and 91.1% after 3 days and 7 days after spraying. Applying pesticides in the same way, the control effects of single agent 15% etofenprox suspension concentrate (application rate is 15 grams / mu) and 20% ZJ4042 suspension agent (application rate is 10 grams / mu) in 3 days after the medicine are respectively 71.2...

Abstract

The present invention discloses an insect disinfestation composition containing two active ingredients, wherein the first active ingredient is ethofenprox, the second active ingredient is 3-chloro-N1-(2-methyl-4-heptafluoroisopropyl phenyl)-N2-(1-methyl-1-cyanoethyl)phthalamide, and the mass ratio is 1-50:20-1. The insect disinfestation and sterilization composition is suitable for control of lepidoptera pests and homoptera pests.

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 etofenprox, etc., have high cost when used alone, which...
