Embodiment 1

[0018] Example 1: Combined effect assay on diamondback moth.

[0019] The tested insects were 2-3 instar larvae of diamondback moth; the test method refers to the Agricultural Industry Standard NY / T1154.2-2006 of the People's Republic of China, Stomach Toxin Activity Test-Poisoned Leaf Method. The co-toxicity coefficient (CTC) of the compound agent (CTC) ≥ 120 showed synergistic effect; CTC ﹤ 80 showed antagonistic effect; CTC ﹤ 80 ﹤ 120 showed additive effect.

[0020] Table 1: The toxicity test results of indoxacarb·beta-cyfluthrin to Plutella xylostella.

[0021]

[0022] It can be seen from Table 1 of the test results that when the mixing ratio of indoxacarb and lambda-cyfluthrin is between 10:1-1:10 (weight ratio), both show synergistic effect on diamondback moth.

Embodiment 2

[0023] Example 2: 12% indoxacarb·beta-cyfluthrin suspension concentrate.

[0024] Indoxacarb 10%, lambda-cyfluthrin 2%, emulsifier 1601# 10%, wetting agent LS, dispersant SOPA-270 3%, bentonite 2%, xanthan gum 0.2%, silicone defoamer 0.5%, Glycerol 5%, the balance is deionized water. The above formula is pre-crushed according to the proportion, then added to a sand mill for grinding, and prepared after high-shear mixing to prepare 12% indoxacarb·beta-cyfluthrin suspension concentrate.

[0025] Table 2: Test results of 12% indoxacarb·beta-cyfluthrin SC mixed with water and sprayed to control diamondback moth.

[0026]

[0027] As can be seen from Table 2, 12% indoxacarb·beta-cyfluthrin SC of the present invention is excellent in controlling Plutella xylostella, and 12% indoxacarb·beta-cyfluthrin SC is more effective than 15% indoxacarb SC and 5% efficient The effect of cyfluthrin SC is good, indicating that 12% indoxacarb·beta-cyfluthrin SC can control Plutella xylostella ...

Embodiment 3

[0028] Example 3: 8% indoxacarb·beta-cyfluthrin EC.

[0029] Indoxacarb 5%, beta-cyfluthrin 3%, non-ionic polyoxyethylene ether 4%, epoxidized soybean oil 2%, p-aminobenzoic acid 0.5%, emulsifier 1601# 10%, emulsifier 500# 5% , and the balance is ethanol and xylene. Add the above formulas into the mixing kettle in sequence according to the proportion, and after stirring evenly, 8% indoxacarb·beta-cyfluthrin emulsifiable concentrate can be prepared.

[0030] Table 3: 8% indoxacarb·beta-cyfluthrin emulsifiable concentrate mixed with water and sprayed to control cotton bollworm test results.

[0031]

[0032] As can be seen from Table 3, 8% indoxacarb·beta-cyfluthrin emulsifiable concentrate of the present invention has excellent efficacy in preventing and treating cotton bollworm, and the ratio of 8% indoxacarb·beta-cyfluthrin emulsifiable concentrate to 150g / L indoxacarb emulsifiable concentrate and 5% beta-cyfluthrin The cream works well. It shows that 8% indoxacarb·beta...

Abstract

The invention relates to an insecticidal composition of indoxacarb and efficient cyfluthrin. The weight ratio of the indoxacarb to the efficient cyfluthrin in the composition is 10:1-1:10; and the insecticidal composition of the indoxacarb and the efficient cyfluthrin, provided by the invention, has an obvious synergistic effect and is mainly used for preventing and treating lepidoptera pests such as asparagus caterpillar, plutella xylostella, cabbage caterpillar, prodenia litura and cabbage moths.

Description

technical field [0001] The insecticidal composition involved in the present invention uses indoxacarb and beta-cyfluthrin as active ingredients, and is used for preventing and controlling lepidopteran pests of crops. Background technique [0002] The problem of resistance to agricultural pests is a global problem and has always been a key topic of concern to agricultural science and technology workers. With the continuation of chemical pest control year after year, 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, which are seriously harmful to agricultural production, have a high degree of resistance, and the speed of resistance development is relatively fast. At the same time, the high-intensity use of pesticides leads to excessive pesticide residues in agricultural products, environmental pollutio...
