Ultra-low volume solution containing epoxiconazole

Abstract

The invention discloses an ultra-low-capacity liquid preparation containing epoxiconazole, which uses epoxiconazole, or a compound of epoxiconazole and active component II as the active ingredient, and is prepared into an ultra-low-volume liquid preparation by adding auxiliary agents and solvents; The active ingredient II is prochloraz, propiconazole, difenoconazole, chlorothalonil, myclobutanil, ricebendazol, thifuramide, rice blastamide, isofridazine, fluazinam and enoxim Any one or both of the strobilurin. The invention is suitable for ultra-low-capacity spraying, low-capacity spraying and electrostatic spraying, and is used for preventing and controlling diseases of large-area planted crops such as rice, corn, wheat, fruit trees, cotton, vegetables, rubber trees, tea trees, forest trees and sugarcane. The invention has the advantages of high work efficiency, quick effect, long duration of effect, water saving, synergistic effect and the like.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to an ultra-low-capacity liquid containing epoxiconazole. Background technique [0002] Epoxiconazole, chemical name: (2RS, 3RS)-1-[3-(2-chlorophenyl)-2,3-epoxy-2-(4-fluorophenyl)propyl]-1H-1, 2,4-Triazole, one of the novel triazole fungicides, inhibits the synthesis of ergosterol and hinders the formation of bacterial cell walls, and has a strong inhibitory effect on the activity of fungal C-14 demethylase . Epoxiconazole can also increase the chitinase activity of crops, lead to the contraction of fungal haustoria, inhibit the invasion of pathogens, and improve the immunity of crops to diseases. Epoxiconazole can effectively control cereal blight, powdery mildew, eye spot disease, leaf spot, powdery mildew, rust on bananas, onions, garlic, celery, kidney beans, melons, asparagus, peanuts, sugar beets and other crops, And diseases such as anthracnose and white rot on grapes. ...

AI Technical Summary

Problems solved by technology

[0017] 1. The work efficiency of the conventional spraying method is low, and the work efficiency per capita is usually only 2 to 5 mu/day, which is difficult to meet the needs of large-scale planting; with the implementation of my country's land transfer policy, the land presents a trend of intensive management, and more and more The large agricultural planting households in my country have increased the continuous planting area of ​​crops; and with the aging of the population and the emergence of labor shortages in China, labor is gradually becoming a scarce resource, labor costs continue to increase, and agricultural production costs continue to increase; agricultural production has obvious seasonality , Pests and diseases often require a lot of manpower to control in a short period of time

[0018] 2. Conventional spraying method needs a lot of water to control diseases and insect pests, usually the water consumption is 450~900L/hm 2 , and in many areas far away from water sources and arid and water-scarce areas, conventional spraying methods are difficult to implement or cannot achieve the desired control effect

[0019] 3. The medicines used in the conventional spraying method have a short duration of action. Since the dosage forms of the medicines used in the conventional spraying method are usually emulsifiable concentrates, water preparations, wettable powders, su
