Problems solved by technology

[0007] When pyriproxyfen and cyantraniliprole are used alone, the drug cost is relatively high, 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

[0037] Example 1: The synergistic effect of the insecticidal composition containing pyriproxyfen and cyantraniliprole on rice planthopper

[0038] Table 1. Combined synergistic effect of insecticidal composition on rice planthopper Nilaparvata lugens

[0039]

[0040]

Embodiment 2

[0041] Example 2: The synergistic effect of the insecticidal composition containing pyriproxyfen and cyantraniliprole on the rice leaf roller

[0042] Table 2. Combined synergistic effect of the insecticidal composition on the rice leaf roller Cnaphalocrocis medinalis

[0043]

[0044] As can be seen from Examples 1 and 2, the insecticidal composition containing pyriproxyfen and cyantraniliprole, within the scope of 1~50:20~1 (by weight), the co-toxicity coefficient is all greater than 120, It shows synergistic effect on rice planthopper and rice leaf roller. The combination of pyriproxyfen and cyantraniliprole is reasonable and feasible.

Embodiment 3、20

[0045] Embodiment 3, 20% pyriproxyfen · cyantraniliprole suspension concentrate

[0046] According to pyriproxyfen 18%, cyantraniliprole 2%, emulsifier 1601# (styrylphenol polyoxyethylene polyoxypropylene ether) 10%, dispersant SOPA-2704, bentonite 2%, xanthan gum 0.1% , 0.4% of silicone defoamer, 5% of glycerin, and the balance of deionized water, each component is pre-crushed, then added to a sand mill for grinding, and after high-shear mixing, 20 % pyriproxyfen · cyantraniliprole suspension concentrate.

[0047] The prepared 20% pyriproxyfen · cyantraniliprole suspension concentrate was used to control Plutella xylostella. At the peak stage of Plutella xylostella larvae, 20% pyriproxyfen · cyantraniliprole suspension concentrate was sprayed evenly with water at 10 g / mu, and the control effects were 91.8% at 3 days and 7 days after spraying and 95.1%. Spray in the same way, contrast single agent 20% pyriproxyfen suspension concentrate (application rate is 30 grams / mu) and...

Abstract

The present invention provides an insect disinfestation composition containing pyriproxyfen and cyhalodiamide, wherein the insect disinfestation composition is used for agricultural pests, and a weight ratio of the pyriproxyfen to the cyhalodiamide is 1-50:20-1. The insect disinfestation composition of the present invention has advantages of high efficiency, low toxicity and long persistence, and can effectively prevent and control homopteran pesta and lepidopterous pests.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to an insecticidal composition containing pyriproxyfen 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-efficiency, low-t...
