Novel environmental protection compound pesticide for preventing and treating rice blast

Abstract

The invention relates to a novel environment-friendly formulated pesticide for preventing rice blast, which is characterized in that the novel formulated pesticide is prepared by the following biological components of densefruit pittany root-bark extract, chitosan oligosaccharide, plant activating protein, tricyclazole, a surface active agent and carriers according to different weight proportions. The novel environment-friendly formulated pesticide is characterized by safety, synergism and environment-friendly and the like, has synergism to the toxicity of the tricyclazole, and can enhance the drug effect thereof while reducing the usage of the tricyclazole, thus achieving the purpose of preventing the rice blast, enhancing the expression of defense enzymes in seedlings of rice, improving the disease resistance of the seedlings and increasing the yield of the rice; the pesticide of the invention can be prepared into wet powder.

Description

Technical field: [0001] The invention relates to a novel environment-friendly compound pesticide for preventing and treating rice blast, which belongs to a kind of pesticide. Background technique: [0002] Rice blast is one of the most widely distributed and most harmful plant fungal diseases, which occurs in almost all rice cultivation areas. The disease can be affected in all growth stages of rice and all parts of the rice plant, mainly affecting leaves, stems, panicles, etc., and has the characteristics of long damage time, many infected parts and diverse symptoms. According to incomplete statistics, the disease can cause an average 10% to 20% yield reduction in normal years, and 40% to 50% in severe plots in epidemic years, or even no harvest. [0003] At present, the prevention and control of rice blast mainly takes measures such as breeding resistant varieties, chemical control and strengthening cultivation management. Most of the disease-resistant varieties are vert...

Problems solved by technology

[0022] The object of the present invention is to provide a new type of environmentally friendly compound pesticide for preventing and treating rice blast. In view of the current situation that the use of chemical pesticides seriously pollutes the environment, extracts of plant-derived biopesticides, chitosan oligosaccharides and microorganisms The source elicitor plant activator protein is mixed with the original drug of tricyclazole to make a biological compound pesticide, which overcomes the shortcomings of high cost, slow effect, and unstable drug effect of biological pesticides alone, and reduces the use of chemical pesticides at the same time. The pressure of chemical pesticides on the environment can increase the bacteriostatic rate of tricyclazole, have a significant synergistic effect on tricyclazole, and play a significant role in the prevention and control of rice blast, and can be used as a biological organic fertilizer to spread and apply
