Germicide composition for preventing and controlling green smut of rice

Abstract

The present invention relates to synergistic germicide composition, which consists of epoxiconazole and prochloraz in the weight ratio of 0.03-65, preferably of 0.05-55, as the active components, and agricultural acceptable assistant. The germicide composition can preventing and treating green smut germ of rice effectively, and has the positive effects of delaying fungus resistance, raising preventing and treating effect, etc. Test shows that the composition has low use cost, safety on plant and environment and other features.

Description

technical field [0001] The invention relates to a fungicide composition with synergistic effect, which can effectively prevent and treat rice false smut disease bacteria, has protective and therapeutic effects on crops, and exhibits extremely strong antibacterial and bactericidal activities. The invention belongs to the field of agricultural plant protection. The fungicide composition is different from other existing fungicides. technical background [0002] Rice false smut, also known as green smut, usually occurs on middle and late rice, and is more common on hybrid rice and high-quality rice. The disease mainly damages the ears, and the serious reduction in yield can reach 10%-20%. With the increase of japonica rice planting and nitrogen fertilizer application level, rice false smut has gradually increased from a minor disease to a major disease. Rice false smut not only affects the yield, but its pathogen is a substance that is toxic to humans, livestock, and poultry a...

Problems solved by technology

Because the compound introduces fluoride ions, it has a particularly high bactericidal activity against rice false smut, but due to the high cost of epoxiconazole, it is difficult to promote it on a large scale

Prochloraz is a broad-spectrum fungicide, which is the most active species among carbamoyl imidazoles. It has good conductivity and is
