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 spirotetramat, 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] Example 1: Mixing of cyantraniliprole and spirotetramat

[0038] Table 1. Synergistic effect of cyantraniliprole and spirotetramat on the aphid Aphis medicagini

[0039] Proportion

[0040] Table 2. Synergistic effect of cyantraniliprole and spirotetramat on the rice leaf roller Cnaphalocrocis medinalis

[0041] Proportion

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

Embodiment 2

[0043] Example 2: 20% spirotetramat · cyantraniliprole suspension concentrate

[0044] Spirotetramat 18%, cyantraniliprole 2%, emulsifier 1601# (styrylphenol polyoxyethylene polyoxypropylene ether) 10%, dispersant SOPA-2704%, bentonite 2%, xanthan gum 0.1%, 0.4% silicone defoamer, 5% glycerin, and deionized water as the balance, the ingredients are pre-crushed in proportion, then added to a sand mill for grinding, and then prepared after high-shear mixing A 20% suspension concentrate of spirotetramat and cyantraniliprole was prepared.

[0045] 20% spirotetramat · cyantraniliprole SC was applied to control Plutella xylostella. 20% spirotetramat · cyantraniliprole SC was sprayed evenly with water at 10 g / mu on the occurrence stage of Plutella xylostella larvae, and the control effects were 93.2% and 97.3% after 3 days and 7 days respectively. Spraying by the same method, contrast single agent 20% spirotetramat suspension concentrate (application rate is 30 grams / mu), 20% chlor...

Embodiment 3

[0046] Example 3: 40% spirotetramat · cyantraniliprole water dispersible granules

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

[0048] 40% spirotetramat · cyantraniliprole water dispersible granule was applied to control aphids. 40% spirotetramat · cyantraniliprole water dispersible granules were sprayed evenly with water at the peak of aphid occurrence at 10 g / mu, and the control effects were 95.4% and 93.5% 3 days and 7 days after the application. Spraying by the same method, contrast single agent 20% spirotetramat suspension concentrate (application rate is 30 grams / mu), 20% chlorflu cyantraniliprole suspension concentrate (application rate is...

Abstract

The invention discloses an insecticidal composition containing two active ingredients. The insecticidal composition contains the two active ingredients, namely spirotetramat 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, existing pesticides such as spirotetramat, etc., have high cost when used alone, wh...
