Pesticide composition for preventing and controlling banana panama disease and water suspension agent thereof

Abstract

The invention provides a pesticide composition for preventing and controlling banana panama disease, and belongs to the technical field of pesticides. The pesticide composite is prepared from the following components in parts by weight: 25 to 40 parts of hymexazol, 10 to 20 parts of chitosan oligosaccharide, and 5 to 10 parts of fluoxastrobin. The pesticide composition for preventing and controlling the banana panama disease has obvious effects of preventing and controlling the banana panama disease. The pesticide composition is prepared into the stable water suspension agent, so that the preparation, use and storage are convenient, and the control effect of the pesticide is favorably played.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a pesticide composition for preventing and treating banana Panama disease and an aqueous suspension thereof. Background technique [0002] Banana Panama disease, also known as banana wilt, is a soil-borne vascular disease caused by Fusarium oxysporum f.sp. Cubense (FOC). It is common in Asia, Africa and America. Pathogens invade from the root system of bananas, colonize and block the vascular bundles, and cause symptoms such as wilting, discoloration and rot of vascular bundles, and yellowing of leaves. If not treated in time, it will cause devastating damage to the plants, and It is very contagious and harmful, which seriously restricts the healthy development of my country's banana industry. [0003] For banana Panama disease, the main control methods include chemical control, biological control and disease-resistant breeding. Breeding for disease resistance is time-consumi...

Problems solved by technology

[0004] Chinese patent application CN103430961 discloses a compound biopesticide for preventing and treating banana wilt-Panama disease, which is composed of oligosaccharin, chitosan and lysozyme, which has the effect of inducing disease resistance of bananas and lysing and sterilizing bacteria, and is environmentally compatible Good, but difficult to make stable pesticide formulations

[0005] Chinese patent application CN 104054699 discloses a hymexazol water agent for preventing and treating banana wilt, which is composed of hymexazol, pesticide adjuvant 06301, water / water and defoamer, and has good water agent stability and pourability , but the control effect on banana fusarium wilt is not ideal

Some chemical pesticide compositions have a good inhibitory effect on Fusarium wilt of banana indoors, such as hymexazol-bromothalonil, carbendazim-propiconazole, etc., but the control effect in the field is not ideal

In the prior art, there are few reports on the combination of biological pesticides and chemical pesticides to achieve good control effects on banana Panama disease
