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, the existing pesticides such as Clothianidin etc. have 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

[0037] Example 1: Mixing of cyantraniliprole and clothianidin

[0038] Table 1. Combined synergistic effect of cyantraniliprole and clothianidin on the aphid Aphis medicagini

[0039] Proportion

[0040] Table 2. Combined synergistic effect of cyantraniliprole and clothianidin on Cnaphalocrocis medinalis

[0041] deal with

[0042] As can be seen from the test results Tables 1 and 2, clothianidin and cyantraniliprole are in the range of 1 to 50:20 to 1 (by weight), and the co-toxicity coefficients are all greater than 120. Leaf rollers showed a synergistic effect. The combination of clothianidin and cyantraniliprole is reasonable and feasible.

Embodiment 2

[0043] Example 2: 20% Clothianidin·Cyantraniliprole Suspension Concentrate

[0044] Clothianidin 18%, cyantraniliprole 2%, emulsifier 1601# (styrylphenol polyoxyethylene polyoxypropylene ether) 10%, dispersant SOPA-2704%, bentonite 2%, xanthan gum 0.1%, silicone defoamer 0.4%, glycerol 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 20% clothianidin · cyantraniliprole suspension concentrate.

[0045] The prepared 20% clothianidin · cyantraniliprole suspension concentrate was applied to control Plutella xylostella. 20% Clothianidin · Cyantraniliprole SC was sprayed uniformly with water at 10 g / mu on the occurrence stage of Plutella xylostella larvae, and the control effects were 92.7% and 96.1% after 3 days and 7 days after spraying. Applying pesticides in the same way, compared with a single dose of 20% clothianidin suspension concentrate (application rate is 30 grams / mu) and 20...

Embodiment 3

[0046] Example 3 (40% clothianidin · cyantraniliprole water dispersible granules)

[0047] According to the formula of clothianidin 35%, cyantraniliprole 5%, sodium lauryl sulfate 6%, polysulfate 4%, sodium chloride 8%, polyethylene glycol 3%, the balance is kaolin , each component is dry crushed in proportion, granulated, dried and sieved to obtain 40% clothianidin · cyantraniliprole water dispersible granules.

[0048] The prepared 40% clothianidin · cyantraniliprole water dispersible granule was applied to control aphids. 40% clothianidin · cyantraniliprole water dispersible granules were sprayed evenly with water at the peak of aphid occurrence at 10 g / mu, and the control effects were 92.8% and 94.8% 3 days and 7 days after the application. Apply pesticides in the same way, contrast single agent 20% clothianidin suspension concentrate (application rate is 30 grams / mu) and 20% chlorofluorocyantraniliprole suspension concentrate (application rate is 10 grams / mu), after the ...

Abstract

The invention discloses an insecticidal composition containing two active ingredients. The insecticidal composition contains the two active ingredients, namely clothianidin and 3-chloro-N1-(2-methyl-4-heptafluoroisopropyl phenyl)-N2-(1-methyl-1-cyanoethyl) phthalimide which are in the mass ratio of (1-50): (20-1). The insecticidal composition disclosed by the invention is applicable to the prevention and treatment of homoptera pests and lepidoptera 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, the existing pesticides such as Clothianidin etc. have high drug costs when used al...
