Embodiment 1

[0084] Example 1 Preparation of 6% emulsifiable concentrate product containing natural pyrethrins and imidacloprid.

[0085] First take the following raw materials by weight:

[0086] 50% natural pyrethrin raw medicine 2kg (effective dose 1kg)

[0087] 90% imidacloprid raw powder 5.6kg (effective dose 5kg)

[0088] Piperonyl butoxide 15kg

[0089] N,N-Dimethylformamide DMF 15kg

[0090] Azone 1kg

[0091] Epoxidized soybean oil 5kg

[0092] Farm milk 600 2kg

[0093]Farm milk 0203 10kg

[0094] Xylene 44.4kg

[0095] Imidacloprid was purchased from Yunnan Jianyuan Biological Development Co., Ltd., and natural pyrethrins were purchased from Zhejiang Qianjiang Biochemical Co., Ltd.

[0096] Then accurately weigh DMF15kg, imidacloprid 5kg respectively; Add imidacloprid in the DMF under stirring condition and fully dissolve, after imidacloprid dissolves, then add successively 1kg natural pyrethrins, 15kg piper...

Embodiment 2-6

[0098] Example 2

Embodiment 7

[0099] Example 7 Preparation of 6% Microemulsion Containing Natural Pyrethrins and Imidacloprid

[0100] First take by weight the following raw materials: 50% natural pyrethrin former drug 4kg, 90% imidacloprid former drug 4.5kg, DMF8kg, cyclohexanone 15kg, azone 1kg, BHT3kg, piperonyl butoxide 5kg, No. 500 agricultural milk 5kg, Nongru No. 600 8kg, Nongru No. 1600 5kg, n-butanol 3kg, ethylene glycol 2kg, tap water 36.5kg.

[0101] Preparation process: Add imidacloprid raw powder into a stirred reactor, then add DMF, stir, after imidacloprid is completely dissolved, add natural pyrethrin, BHT, cyclohexanone, stir to obtain natural pyrethrin·imidacloprid mixed solution, then add in sequence Azone, piperonyl butyl ether, Nongru No. 500, 600, 1600, n-butanol, ethylene glycol, stir the organic phase uniformly, add tap water to the organic phase and stir for 30 minutes under the same stirring conditions to obtain 6% containing natural pyrethrins and imidacloprid microemulsion prod...

Abstract

A composite agricultural chemical with high effect and broad spectrum contains natural pyrethrins (0.2-10 Wt%), imidacloprid (1-10) and assistant (rest).

Description

technical field [0001] The invention relates to a pesticide composition containing natural pyrethrins and imidacloprid and an application thereof, belonging to the field of pesticides. Background technique [0002] With the massive and unreasonable use of chemical pesticides, especially highly toxic and high-residue organic synthetic pesticide products, while protecting the stable and high yield of crops, it will inevitably cause environmental pollution, excessive pesticide residues in agricultural products, and increased resistance of harmful organisms. series of questions. In response to these problems, people are increasingly calling for the development and use of environmentally friendly pesticides with high efficiency, low toxicity and low residue. [0003] In the process of tobacco production, tobacco is seriously harmed by various diseases and insect pests, resulting in reduced yield and poor quality. Wherein, tobacco aphid (Myzus persicae), also known as Myzus pers...
