Abstract

The invention discloses a bactericidal composition containing isotianil and osthole, and belongs to the technical field of pesticide preparation. The bactericidal composition comprises, by weight, 1-50% of isotianil, 0.1-10% of osthole, 5-10% of a bactericidal aid, and the balance of auxiliary components. According to the sterilization auxiliary agent, modified chitosan serves as a carrier, after rice absorbs the modified chitosan, the fertilizer and water absorption capacity, drought resistance and lodging resistance of plants can be enhanced, immunity is enhanced, meanwhile, plant seeds are promoted to germinate in advance, roots are promoted to be developed, the number of root hairs, fibrous roots and secondary roots is greatly increased, the rhizosphere state is fully activated, and nutrient molecules are dissolved, so nitrogen, phosphorus and potassium nutrients are effectively and sufficiently absorbed by rice; and the sterilization auxiliary agent contains the ketoxime ether structure, so the sterilization auxiliary agent cna kill bacteria, has low toxicity, and can well prevent rice from being invaded by rice blast and other diseases by compounding the sterilization auxiliary agent with isotianil and cnidium lactone.

Description

technical field [0001] The invention relates to the technical field of pesticide preparation, in particular to a bactericidal composition containing Isotianil and osthole. Background technique [0002] Isotianil is an isothiazole fungicide jointly developed by Bayer and Japan’s Sumitomo Chemical Company to prevent and control rice blast. It is characterized in that it does not have a direct antibacterial effect on pathogenic bacteria, but stimulates the natural defense mechanism of rice itself against rice blast. , in order to achieve the purpose of resisting rice blast. [0003] In the field of pesticide technology, commonly used and reasonable chemical fungicide compounding or mixing can expand the bactericidal spectrum, improve the control effect, extend the application period, reduce the dosage, reduce the drug damage, reduce the residue, delay the fungal drug resistance and anti-bacteria. Positive features such as the occurrence of medicinal properties. [0004] The b...
