Problems solved by technology

At present, the main control method for such pests in our country is still chemical control, but with the continuous increase and innovation of the types of pesticides, due to the lack of understanding and unreasonable mix and match of pesticides, people began to abuse them in large quantities. This not only fails to achieve good economic benefits, but also causes environmental pollution and increased resistance of pests, and some even seriously harm their natural enemies.

Embodiment 1

[0020] A compound pesticide for preventing and treating Lygus lucidum, its raw materials are composed of 3% of pymetrozine, 12% of bifenthrin, 2% of hypertonic agent, 5% of emulsifier and the balance of solvent according to weight percentage.

[0021] Its preparation method is as follows: pymetrozine and bifenthrin are completely dissolved with an appropriate amount of solvent respectively, and then mixed uniformly; then, a hypertonic agent and an emulsifier are sequentially added to it, and the remaining amount of solvent is added, and a uniform and transparent solution is obtained by stirring. It is the target compound pesticide.

[0022] The hypertonic agent described in this example is azone, the emulsifier is pesticide emulsifier 2201, and the solvent is N,N-dimethylformamide.

[0023] The pesticides prepared above were compounded, and the liquid tube drug film method improved by referring to the NY / T1154.8-2007 filter paper film method was used for the control of Lygus l...

Embodiment 2

[0025] A compound pesticide for preventing and treating Lygus lucidum, the raw materials of which are composed of 10% pymetrozine, 20% bifenthrin, 4% hyperosmotic agent, 10% emulsifier, and the balance of solvent according to weight percentage.

[0026] Its preparation method is as follows: pymetrozine and bifenthrin are completely dissolved with an appropriate amount of solvent respectively, and then mixed uniformly; then, a hypertonic agent and an emulsifier are sequentially added to it, and the remaining amount of solvent is added, and a uniform and transparent solution is obtained by stirring. It is the target compound pesticide.

[0027] The hypertonic agent described in this example is azone, the emulsifier is Pesticide Emulsifier 500, and the solvent is N,N-dimethylformamide.

[0028] The pesticides prepared above were compounded and used for the actual control of Lygus chlorophylla, and the mortality rate reached 97.63%.

Embodiment 3

[0030] A compound pesticide for preventing and treating Lygus viridatus, its raw materials are composed of 18% of pymetrozine, 18% of bifenthrin, 3% of hyperosmotic agent, 10% of emulsifier, and the balance of solvent according to weight percentage.

[0031] Its preparation method is as follows: pymetrozine and bifenthrin are completely dissolved with an appropriate amount of solvent respectively, and then mixed uniformly; then, a hypertonic agent and an emulsifier are sequentially added to it, and the remaining amount of solvent is added, and a uniform and transparent solution is obtained by stirring. It is the target compound pesticide.

[0032] The hypertonic agent described in this example is azone, the emulsifier is Pesticide Emulsifier 500, and the solvent is N,N-dimethylformamide.

[0033] The pesticides prepared above were compounded and used for the actual control of Lygus chlorophylla, and the mortality rate reached 96.66%.

Abstract

The invention belongs to the technical field of compound pesticides, and in particular relates to a compound pesticide for preventing and treating lygus lucorum and a preparation method of the compound pesticide. The compound pesticide is prepared from effective constituents of pymetrozine and bifenthrin, aiming at the problems that at present, the selection of pesticide is not proper, the dosage of the pesticide is not accurate, the pesticide application is not timely, and the pesticide application method is not accurate, so as to cause the severe results that labor, time and pesticide are wasted, the pollution is heavy, the insects have strong resistance to pesticides, and the pesticide residue of the crop is serious. The compound pesticide is prepared from effective constituents of pymetrozine and bifenthrin, the pesticide effects of pymetrozine and bifenthrin are increased, the spray times is reduced, the resistance is delayed, the life of the crop is prolonged, and the environment pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides, and in particular relates to a compound pesticide for preventing and treating Lygus lucidum and a preparation method thereof. Background technique [0002] Green Lygus scientific name Apolygus lucorum (Meyer-Dür), belongs to Hemiptera, Miridae, Lygus genus. Widely distributed in the cotton areas of the country, it has always been a secondary pest of agricultural production in my country. In recent years, with the adjustment of the agricultural industry structure, the planting area of ​​fruit trees and vegetables has been greatly increased, providing abundant host plants and Suitable places for overwintering and the large-scale planting of transgenic insect-resistant cotton have reduced the amount of pesticides used to control cotton bollworms (also for the treatment of Lygus spp.), resulting in Lygus spp. becoming the dominant population in cotton fields, which not only seriously harm...
