Abstract

The invention discloses an efficient ecological insecticidal fungicide with a slow release function. The fungicide is prepared from chitosan, chitosan oligosaccharide, alginate, humic acid, azone, phosphite diester compounds and benzoic acid. The invention further discloses a preparation method of the insecticidal fungicide. The efficient ecological insecticidal fungicide with the slow release function has the high insecticidal and fungicidal effect and the slow release and controlled release effect, is long in insecticidal and fungicidal lasting period, can decrease the insecticide dosage, is efficient, environmentally friendly, free of residues and capable of achieving the broad-spectrum insecticidal effect, and has the important social benefit, economic benefit and ecological benefit.

Description

technical field [0001] The invention relates to the technical field of pesticide preparation, in particular to a high-efficiency ecological insecticide and antibacterial agent with slow-release function and its use method and application. Background technique [0002] my country is a large agricultural country, the production of chemical pesticides ranks second in the world, and the utilization rate ranks the highest in the world. Tens of thousands of people are poisoned by pesticides every year, 70% of which are poisoned by organophosphorus pesticides, and their environmental pollution and ecological damage are extremely serious. . Therefore, reducing the use of chemical pesticides, enhancing the ability of green plants to prevent and resist diseases, using biological products and measures to enhance the healthy growth of plants themselves, and realizing a virtuous circle of ecology are the research focuses in the field of agricultural applications in the world today. In or...
