Pesticide for preventing grape diseases and pests at young fruit stage and preparation method thereof

Abstract

The invention discloses pesticide for preventing grape diseases and pests at the young fruit stage and a preparation method thereof. The pesticide is prepared from, by weight, fruits of cubeb litsea trees, n-hexane, concentrated sulfuric acid with the concentration being 95-98%, lemon grass oil, salicylic acid, validamycin, N,N-dimethyl carbamate, white carbon black micro powder, willow leaves, melia azedarach fruits, orange peel, ginger juice, betel nuts and a proper amount of water. At the young fruit stage of grapes, bacteroidal diseases are mainly prevented, the bactericidal performance of the pesticide is improved and can be effective for a long time, and the preventive effect can be achieved and is one main characteristic of the pesticide; meanwhile, plant type antibacterial materials are adopted for refining, biologically antibacterial substances are obtained, the using quantity of chemical poisonous substances is reduced, sedimentation of chemical toxicants is reduced, and planted grapes can be safe and hygienic.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide for preventing and controlling grape diseases and insect pests in the young fruit stage and a preparation method thereof. Background technique [0002] In recent years, my country has used 1 million tons of pesticides every year to prevent and control crops with an area of ​​more than 300 million hectares. Plant protection has made a huge contribution to the agricultural harvest and played a role in escorting the safety of the crops. Seriously insufficient research, ignoring the research on target biological behavior and the widespread use of large-capacity, large-droplet spraying technology and other reasons, the effective utilization rate of pesticides in my country is low, and only 20-30% of the pesticides dispersed by pesticide application equipment can be deposited on crops. Equivalent to 50% of the average level in developed countries, the low effic...

Problems solved by technology

[0002] In recent years, my country has used 1 million tons of pesticides every year to prevent and control crops with an area of ​​more than 300 million hectares. Plant protection has made a huge contribution to the agricultural harvest and played a role in escorting the safety of the crops. Seriously insufficient research, ignoring the research on target biological behavior and the widespread use of large-capacity, large-droplet spraying technology and other reasons, the effective utilization rate of pesticides in my country is low, and only 20-30% of the pesticides dispersed by pesticide application equipment can be deposited on crops. Equivalent to 50% of the average level in developed countries, the low efficiency of pesticide use not only wastes a lot of pesticides, but also causes a large amount of pesticide preparations to be lost to non-target environments, causing human and animal poisoning, environmental pollution, and increased pesticide residues in agricultural products

[0003] The low efficiency of pesticide use is also closely related to the lack of research on pesticide processing technology. my country has become a major producer of pesticides, but there is still a big gap between domestic preparations, dosage forms and product quality compared with foreign countries, mainly manifested in dispersibility Poor, low suspension rate, high thermal storage decomposition rate, etc. Some formulations have unstable efficacy due to poor wettability, permeability and leaf deposition, which means that some varieties are obviously poor in rain erosion resistance and viscosity. Compared with similar foreign products, such as domestic pesticide water suspension concentrates, there are generally problems such as water separation, thickening, sedimentation, caking and other storage stability.
