Abstract
The invention discloses a composition and an application method for efficiently preventing and treating rice blast, belonging to the technical field of agricultural biological control. The composition for effectively preventing and treating rice blast is made of the following raw materials in parts by weight: 10-20 parts of allylbenzothiazole, 5-10 parts of Bacillus subtilis, 5-10 parts of active ingredient extracts of Chinese herbal medicines, surface active Dose 8‑15 parts. The present invention combines chemical inducers, microbial preparations and active ingredients of Chinese herbal medicines, and significantly improves the efficacy of the composition in preventing and treating rice blast through the synergistic effect between the raw materials; by inoculating the rice blast fungus at the seedling stage in the greenhouse, it is determined that the product of the present invention is effective against rice blast. The control effect of rice blast, the results show that the product of the application has a control effect of more than 84% on rice leaf blast and panicle blast; the product of the present invention is green and environmentally friendly, and the selected raw materials will not cause secondary pollution to the environment, nor will it It is the best way to prevent and control rice blast and is of great significance to promote the sustainable development of agriculture.
Description
technical field [0001] The present invention relates to a composition and an application method for efficiently preventing and controlling rice blast, in particular to a green and environment-friendly composition prepared by comprehensively utilizing chemical inducers, microbial inoculants and functional active substances of Chinese herbal medicine, which can effectively prevent and control rice blast. , belonging to the field of agricultural biological control technology. Background technique [0002] Rice is the main food crop in my country and occupies an important position in agricultural production. At present, it has become the food crop with the most extensive planting area in my country. The prevention of its diseases is of great significance to increase rice production. Rice blast is a devastating disease caused by the fungus Magnaporthe oryzae on rice. It occurs to varying degrees every year. Generally, rice blast can reduce rice production by 10% to 20% in epidemi...
