Embodiment 1

[0029] Embodiment 1: Toxicity determination test

[0030] In order to evaluate the toxicity of different ratios of acephate and cyhalothrin to cotton bollworm, evaluate the synergistic effect of acephate on cyhalothrin, and determine the optimal ratio of the two, we Toxicity testing was carried out to provide theoretical basis and registration materials for scientific and reasonable formula combination.

[0031] Toxicity determination test: This test adopts the dipping method, and dilutes different test agents into 6 concentrations according to the design requirements. On the basis of the preliminary test, select 15 3-year-old test insects for each concentration treatment, repeat 3 times, and use clean water to do the test. Blank control. When processing, immerse the test insects in the liquid medicine, take them out after 5 seconds, absorb the excess liquid medicine on the insect body with absorbent paper, let it cool at room temperature, put it into a small box containing f...

Embodiment 2

[0038] Embodiment two: the compound pesticide of cyhalothrin and acephate, represented by weight percentage, cyhalothrin 4%, acephate 36%, emulsifier phenethylphenol polyoxyethylene ether ( That is, Nongru No. 600) 22%, antifreeze ethylene glycol 3%, and the balance is water.

[0039] Production method: firstly weigh each raw material medicine according to the proportion, add emulsifier, antifreeze agent, add water to make up to 100%, stir evenly in a reaction kettle to make a microemulsion, and then pack and pack to obtain the product. The packaging strictly follows GB3796-2006 General Rules for Pesticide Packaging, and the pesticide label strictly follows GB20813-2006 General Rules for Pesticide Product Labels.

[0040]Spraying period and method: From June to October each year, during the activity period of cotton bollworm, dilute 80-120g / mu microemulsion with 1000 times water, and then spray it.

Embodiment 3

[0041] Embodiment three: basically the same as embodiment two, the difference is:

[0042] A compound pesticide of cyhalothrin and acephate, composed of: 5% cyhalothrin, 35% acephate, 24% emulsifier phenethylphenol polyoxyethylene ether, antifreeze ethylene glycol Alcohol 3%, the balance is water.

Abstract

The invention relates to a composite pesticide containing cyhalothrin and acephate, which is mainly used for controlling cotton bollworm that is the pest of cotton. The composite pesticide comprises the components by weight percent: 1-5% of cyhalothrin and 32-39% of acephate which are added with emulsifying agent and antifreeze agent and then added with water for supplementing to 100%. After the cyhalothrin and the acephate are compounded with each other, indoor toxicity measurement proves that the synergia multiples of the product are 199.14, thus remarkably improving the effect; furthermore, the composite pesticide can greatly reduce the control times of the cotton bollworm, improves the control rate, lightens the labor intensity and reduces the environmental pollution. The form of the composite pesticide is microemulsion which takes the water as solvent, so that a great deal of organic solvent can be saved, and the safety of the product is improved. After being compounded, the pesticide not only has the reduced toxicity and production cost, but also ensures the control effect and expands the controlled objects, so as to improve the simultaneous control effect, prolong the residual effect period and greatly enhance the cost performance of the product.

Description

1. Technical field: [0001] The invention relates to a compound pesticide for cotton pests, in particular to a compound pesticide of cyhalothrin and acephate mainly used for controlling the cotton pest bollworm. 2. Background technology: [0002] Cotton bollworm (Heliothis armigera H.) is one of the main pests of cotton. After the mid-1990s, with the promotion and popularization of transgenic insect-resistant cotton, the harm of cotton bollworm was effectively controlled, and cotton fields were rarely treated with chemical pesticides for cotton bollworm damage. However, in recent years, the harm of cotton bollworm on cotton has become increasingly serious, and insect-resistant cotton varieties in many places also need to carry out repeated bollworm control, and on other crops such as soybeans, peanuts, corn and vegetables, bollworms have also been eliminated. It has risen to be one of the major pests with serious damage. [0003] Cyhalothrin is a moderately toxic insecticid...
