Compound bactericide for preventing and treating wheat scab

Abstract

The invention discloses a compound bactericide for preventing and treating wheat scab. The compound bactericide is prepared from albendazole and tebuconazole as base materials according to a mass ratio of albendazole to tebuconazole of 7: 1 to 1: 7. Preferably, a mass ratio of albendazole to tebuconazole is 1:2. The albendazole is a bactericide raw drug having a mass fraction of 97% and the tebuconazole is a bactericide raw drug having a mass fraction of 98.43%. The two reaction base materials in the compound bactericide do not undergo a chemical reaction and produce obvious synergism or combined effects and thus the compound bactericide is safe in use and has good poisoning activity to different types of wheat scab fungi in the field, wherein the poisoning activity is obviously higher than that of an albendazole or tebuconazole single agent. The compound bactericide is suitable for preventing and treating wheat scab in the vast rural areas.

Description

technical field

[0001] The present invention is related to fungicides, specifically, it belongs to fungicides containing organic compounds, and furthermore, it belongs to fungicides for preventing and treating wheat scab. technical background

[0002] Fusarium graminearum Sehw, scientific name of wheat scab, is one of the main diseases of wheat. Wheat scab occurs widely all over the world, mainly in humid and semi-humid areas, especially in humid and rainy temperate regions. It can suffer from seedlings to heading, mainly causing seedling wither, stem base rot, culm rot and ear rot, of which the most serious damage is ear rot. Wheat head blight is caused by a variety of Fusarium species, collectively known as Gibbrelia zeae (Schw.) Petch].

[0003] Albendazole is an efficient, safe and broad-spectrum imidazole fungicide. It has a significant control effect on a variety of plant diseases, and has a certain effect of increasing yield. Not ideal; Tebuconazole is a highly eff...
