Problems solved by technology

Due to the lack of effective antigen materials, rice varieties with high resistance to sheath blight and rice false smut have not yet been bred. For a long time, Jinggangmycin has been used for the control of pesticide varieties, but Jinggangmycin has been used for more than 20 years, and the dosage is increasing. In particular, the frequency of rice sheath blight control has increased from 2 times a year 20 years ago to 3-4 times at present, and the amount of use has increased from 1.5kg / hm2 to 4.5-6.0kg / hm2, and the control effect has gradually declined. It is imperative to screen and develop pesticide varieties for the prevention and treatment of mid-late rice diseases

Abstract

The invention relates to a bactericide containing benzene kresoxim-methyl and validamycin A and used for the prevention and treatment of rice sheath blight disease and green smut, belonging to the technical field of agricultural chemicals. The bactericide containing benzene kresoxim-methyl and validamycin A contains the effective ingredients of benzene kresoxim-methyl and validamycin A, wherein the weight ratio of the benzene kresoxim-methyl and the validamycin A is 1:50-5:1. According to actual tests, the bactericide has outstanding prevention and treatment effect against rice sheath blight disease and green smut. Compared with conventional bactericides, the bactericide of the invention has the following advantages of: 1, obvious synergized action against rice sheath blight disease and green smut compared with single bactericide and being capable of remarkably enhancing the prevention and treatment effect; 2, being capable of replacing a part of medium / high-toxicity bactericides, lowering dose, reducing environmental pollution and residual quantity on agricultural products; 3, being capable of delay the resistance of rice sheath blight disease and green smut to single bactericide; and 4, long effecting period and lowered cost compared with single bactericide.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a fungicide containing dikestrobin and Jinggangmycin A which can be used for preventing and treating rice sheath blight and rice smut. Background technique [0002] Rice is one of the main food crops in my country. Sheath blight and rice false smut are the main diseases in the middle and late stages of rice. With the large-scale promotion of light rice cultivation technology and high-yield and high-quality varieties, the growth period of rice is prolonged, and the occurrence of rice false smut is inevitable. The aggravating trend, especially the rice with more nitrogen fertilizer and green growth is more prone to sheath blight, especially in high-yielding rice areas. Due to the lack of effective antigen materials, rice varieties with high resistance to sheath blight and rice false smut have not yet been bred. For a long time, Jinggangmycin has been used for the control of pestici...
