Embodiment 1

[0031] The present embodiment provides a kind of insecticidal suspension:

[0032] Emamectin B 2a The mass percentage of benzoate, spinosad and steviol glycoside is 40:1:0.5. emamectin B 2a Benzoate 40%, Spinosad 1.0%, Block Polyether 2.0%, Alkylphenol Polyoxyethylene Ether Phosphate 3.5%, Xanthan Gum 0.3%, Ethylene Glycol 5.0%, Magnesium Aluminum Silicate 0.2 %, steviol glycoside 0.5%, deionized water to make up to 100%. The above-mentioned components are uniformly mixed, and ground by a grinder to obtain the insecticidal suspension.

Embodiment 2

[0034] The present embodiment provides a kind of insecticidal microemulsion:

[0035] Emamectin B 2a The mass percentage of benzoate, spinosad and steviol glycoside is 33:2:0.1. emamectin B 2a Benzoate 33.0%, spinosad 2.0%, phenethylphenol polyoxyethylene ether phosphoester 10.0%, nonylphenol polyoxyethylene ether 10.0%, sec-butyl acetate 25.0%, N,N-dimethyl Formamide 5.0%, steviol glycoside 0.1%, deionized water to make up to 100%.

[0036] emamectin B 2aBenzoate, spinosad, sec-butyl acetate, N,N-dimethylformamide, nonylphenol polyoxyethylene ether and phenethylphenol polyoxyethylene ether phosphoester were mixed uniformly to obtain an oil phase; The steviol glycoside is dissolved in deionized water to obtain a water phase; under the condition of stirring, the water phase is added to the oil phase and mixed uniformly to obtain the insecticidal microemulsion.

Embodiment 3

[0038] The present embodiment provides a kind of insecticidal microcapsule suspension:

[0039] Emamectin B 2a The mass percentage of benzoate, spinosad and steviol glycoside is 10:10:0.8. Take emamectin B2a benzoate 10.0%, spinosad 10.0%, naphthalene sulfonate 2.0%, nonylphenol polyoxyethylene ether 4.0%, sec-butyl acetate 20.0%, mineral spirits 8.0%, Silicone 0.3%, xanthan gum 0.3%, triethanolamine 1.0%, polyisocyanate 4.0%, ethylene glycol 2.0%, sodium benzoate 0.2%, steviol glycoside 0.8%, deionized water to make up to 100%.

[0040] The preparation process is as follows:

[0041] Step 1. Dissolve emamectin B2a benzoate and spinosad in sec-butyl acetate and solvent oil respectively, add polyisocyanate and naphthalenesulfonate, and stir evenly to obtain an oil phase;

[0042] Step 2, adding nonylphenol polyoxyethylene ether, sodium benzoate, and organic silicon to deionized water to obtain an aqueous phase;

[0043] Step 3, under stirring, the oil phase is added to the ...

Abstract

The invention relates to the technical field of preparation of farm chemicals, and particularly discloses an insecticidal composition as well as a preparation and application thereof. According to thecomposition, emamectin B<2a> benzoate, pleocidin and steviol glycoside are compounded, wherein the emamectin B<2a> benzoate and the pleocidin are synergistic, the plant extract steviol glycoside is further added as a synergist, the synergistic interaction effect is achieved through the plant extract steviol glycoside, the emamectin B<2a> benzoate and the pleocidin; meanwhile, the special structure and fragrant and sweet taste of the steviol glycoside can attract the feeding behavior of pests, and the pesticide effect is further improved. According to the insecticidal composition provided by the invention, by selecting and compounding the raw materials with different action mechanisms, the prevention and treatment effect on thrips pests is remarkably improved, the lasting period is long, environmental compatibility is good, drug resistance of the pests is not easy to generate after long-term use, and the insecticidal composition has a great popularization value.

Description

technical field [0001] The invention relates to the technical field of pesticide preparation, in particular to an insecticidal composition and its preparation and application. Background technique [0002] Thrips are insects of the order Thysanoptera of Insecta, which are common insect pests on vegetables, melons, rice and other crops. Thrips occur all year round, mainly in open fields in spring, summer and autumn, and in greenhouses in winter , which suck the juice of young plant tissues (twigs, leaves, flowers, fruits, etc.) with adults and nymphs, and the damaged young leaves and shoots become hard, curl and wither, the plant grows slowly, and the internodes are shortened; young fruits (such as Eggplant, cucumber, watermelon, etc.) will harden after being killed, and cause fruit drop in severe cases, seriously affecting yield and quality. Thrips pests are small in size and often hide in plant flower buds. They are not easy to find, and they have strong fecundity. They ca...
