Embodiment 1

[0019] Weigh nitenpyram and silfluthrin and use conventional preparation methods to prepare emulsifiable concentrates with an effective ingredient content of 25% by mass in different proportions. The specific proportions are shown in Tables 1 and 2:

[0020] Using the method of soaking insects and soaking leaves for indoor synergistic bioassay, select the resistant cotton aphid as the target pest, repeat each treatment 3 times, use LC 50 The value is calculated by Sun Yunpei's method of co-toxicity coefficient:

[0021] Table 1. Indoor toxicity determination of nitenpyram and silfluthrin compound and its single dose against cotton aphid:

[0022]

[0023] The data in the table shows that the blending of nitenpyram and silfluthrin has a synergistic effect on cotton aphids. The co-toxicity coefficients of the three ratios listed in the table are all much greater than 120, so nitenpyram and flusilin The blending of pyrethroid has a significant synergistic effect.

[0024] Using leaf soak...

Embodiment 2

[0038] Weigh 5g nitenpyram and 5g silfluthrin in 8g xylene, add 1g ethylene glycol and 5g alkylphenol polyoxyethylene ether disodium sulfosuccinate, and stir well. Pour the above solution slowly into the remaining amount of water, and fully stir to prepare a 10% nitenpyram·fluthrin water emulsion.

Embodiment 3

[0040] Weigh 1.5g nitenpyram and 8.5g silfluthrin in 8g xylene, add 1g ethylene glycol and 5g alkylphenol polyoxyethylene ether disodium sulfosuccinate, and stir well. Pour the above solution slowly into the remaining amount of water, and fully stir to prepare a 10% nitenpyram·fluthrin water emulsion.

Abstract

The invention discloses a synergistic insecticidal composition containing nitenpyram and fluorosilicone permethrin and application thereof. The synergistic composition comprises the main effective components of nitenpyram and fluorosilicone permethrin, wherein the weight rate of the nitenpyram to the fluorosilicone permethrin is 0.1-80:0.1-55. The synergistic insecticidal composition can be used for preventing and treating hemiptera pests, can generate higher synergy, overcome and delay drug resistance of the pests, expand preventing and treating spectrum and reduce drug cost, has high insecticidal speed and obviously higher preventing and treating effects on aphid and whitefly than a single agent.

Description

Technical field [0001] The invention relates to an insecticidal composition and its application, in particular to an insecticidal composition with nitenpyram and silfluthrin as active ingredients and its application. Background technique [0002] Nitenpyram, the chemical name is (E)-N-(6-chloro-3pyridylmethyl)-N-ethyl-N'-methyl-2-nitrovinylidene diamine. The structural formula is as follows: [0003] [0004] This medicine has a wide insecticidal spectrum and is widely used in agriculture and horticulture to control aphids, leafhoppers, thrips, and hemiptera pests. It has low toxicity and long-lasting efficacy. It has no phytotoxicity to crops and is safe to use; it acts on nicotine type Acetylcholine receptors have unique methods and excellent systemic and osmotic effects, but the drug is expensive. [0005] Alphacypermethin chemical name: (4-ethoxybenzene) [4-fluoro-(3-phenoxybenzene) propyl] dimethyl silane, is a new type of silicon-containing organic insecticide , With stomach...
