Problems solved by technology

[0007] Quetiafos and cyantraniliprole alone are expensive to use, which limits their popularization and application to a certain extent, and long-term single use is likely to increase the degree of pest resistance

Embodiment 1

[0039] Example 1: Mixing of cyantraniliprole and quinathion

[0040] Table 1. Combined synergistic effect of cyantraniliprole and quinathion on cabbage caterpillar (Pieris rapae)

[0041] Proportion

[0042] Cyflunraniliprole

[0043] Table 2. Combined synergistic effect of cyantraniliprole and quinalphos on rice leaf roller (Cnaphalocrocis medinalis)

[0044] Proportion

[0045]As can be seen from Table 1 and 2 of the test results, Quetiafos 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, which is effective against Chilorrhizae cabbage and S. Rice leaf rollers all showed synergistic effect. The combination of quinathion and cyantraniliprole is reasonable and feasible.

Embodiment 2

[0046] Embodiment 2 (20% Quetiafos-Cyantraniliprole Suspension Concentrate)

[0047] Quetiafos 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 the balance is deionized water. The components are pre-crushed, then added to a sand mill for grinding, and finally obtained after high-shear mixing 20% Quetiafos-Cyantraniliprole Suspension Concentrate.

[0048] The prepared 20% Quinthion·Cyantraniliprole SC was used for the control of rice stem borer. 20% Quetiafos-Cyantraniliprole SC was mixed with water and sprayed evenly at 10 g / mu at the peak occurrence stage of rice stem borer larvae, and the control effects were 94.7% and 7 days after spraying, respectively. 95.9%. Spray in the same way, contrast single agent 25% quinthion emulsifiable concentrate (application rate is 100 grams / mu) and 20% chlorflucytraniliprole suspension conc...

Embodiment 3

[0049] Example 3 (40% Quetiafos-Cyantraniliprole Water Dispersible Granules)

[0050] According to the formula of quinathion 35%, cyantraniliprole 5%, sodium lauryl sulfate 6%, polycarboxylate 4%, sodium chloride 8%, polyethylene glycol 3%, the balance is kaolin , each component is subjected to dry pulverization, granulation, drying and sieving to obtain 40% Quetiafos-Cyantraniliprole water-dispersible granules.

[0051] The prepared 40% Quinthion·Cyantraniliprole water dispersible granule was used for the control of cabbage caterpillar. 40% Quetiafos-Cyantraniliprole water-dispersible granules were sprayed evenly with water at the peak of larvae occurrence at an amount of 10 g / mu, and the control effects were 92.3% and 3.6% at 3 days and 7 days after the application. %. Spray in the same way, contrast single agent 25% quinthion emulsifiable concentrate (application rate is 100 grams / mu) and 20% chlorflucytraniliprole suspension concentrate (application rate is 10 grams / mu),...

Abstract

The invention provides an insecticide composition containing quinalphos and cyhalodiamide. The insecticide composition is used for killing agricultural insects. The weight ratio of the quinalphos to the cyhalodiamide is 1-50:20-1. The insecticide composition is efficient, low in toxicity, long in lasting effect and capable of preventing and controlling crop lepidoptera pests effectively.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to an insecticidal composition containing quinalfos and cyantraniliprole. 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. Especially the lepidopteran pests that seriously damage agricultural production have a high degree of resistance and relatively fast development of resistance. At the same time, the high-intensity use of pesticides leads to excessive pesticide residues in agricultural products, environmental pollution and increased costs of pesticides for farmers, which is not conducive to the sustainable development of agriculture. Therefore, the research and development of high-efficien...
