Embodiment 1

[0035] Get the former medicine 3.0kg that the mass fraction of prothioxazole that Guizhou Daoyuan Biotechnology Co., Ltd. The base material is compounded into 4.0kg compound fungicide for preventing and treating rice blast. The effect of controlling rice blast in the field is very good.

Embodiment 2

[0037] Get the prothiozole produced by Guizhou Daoyuan Biotechnology Co., Ltd. as 3.0kg of the original drug with a mass fraction of 98%, and then take the imidabazole provided by Wuhan Jingchu Chen’s Pharmaceutical Chemical Co., Ltd. as 3.0kg of the original drug with a mass fraction of 98% As a base material, it is compounded into 6.0kg of compound fungicides for preventing and treating rice blast. The effect of controlling rice blast in the field is good.

[0038] The above-mentioned compound fungicides have been used in a certain place in Guizhou, and all have achieved good results in the control of rice blast. Among them, the compound fungicide with a mass ratio of imidafurazole:prothiozole of 1:3 has the best control effect.

Abstract

Fungicide formed by compounding prothioconazole and miconazole and used for preventing and treating rice blast is characterized by being prepared by compounding the prothioconazole and the miconazole which serve as base material according to the mass ratio of the miconazole to the prothioconazole being from 1:1 to 1:7; and the prothioconazole is an original medicine with the mass percentage being 98 percent, and the miconazole is an original medicine with the mass percentage being 98 percent. Preferably, the fungicide for preventing and treating rice blast is compound fungicide prepared by compounding the prothioconazole and the miconazole according to the mass ratio of the miconazole to the prothioconazole being 1:3. According to the fungicide, after the two base materials are mixed, the two base materials do not generate chemical reaction, so the fungicide has remarkable synergistic effect, is safe to use, has high toxic activity which is obviously higher than that of miconazole and prothioconazole single agents, and is suitable for the vast rural areas to prevent and treat rice blast.

Description

technical field [0001] The present invention relates to fungicides, specifically, belongs to fungicides containing organic compounds, and furthermore, belongs to fungicides for preventing and treating rice blast. technical background [0002] Rice blast (Pyricularia eryzae) is a disease in the process of rice planting. It is widely distributed and is distributed in all major rice areas in my country. After the onset, it generally reduces yield by 3% to 50%, and especially severe fields even fail to harvest. Rice blast is caused by anamorphic Pyricularia grisea (Cooke) Sacc and asexual Pyricularia oryzae Cav. At present, the use of disease-resistant varieties and the interplanting of varieties with different genetic backgrounds are gradually used in production to comprehensively control the occurrence and damage of rice blast. However, due to the complex and highly variable physiological races of pathogens, the resistance of varieties is difficult to last. Therefore, various...
