Composition for preventing and treating phoma stem canker of rape

Abstract

The invention provides a composition for controlling phoma stem canker of rape, belonging to the field of pesticides. The composition for controlling phoma stem canker of rape comprises active ingredients of 10-50 percent by mass of carbendazim and 1-20 percent by mass of tebuconazole. The active ingredients of the composition provided by the invention comprise carbendazim and tebuconazole, and thus the composition is excellent in controlling effect for the phoma stem canker of rape. Contrast tests indicate that the controlling effect of the composition provided by the invention is greater than the sum of controlling effects of the carbendazim and the tebuconazole which are respectively applied for the phoma stem canker of rape, which shows that the carbendazim and the tebuconazole in the composition provided by the invention have a remarkable synergistic effect on controlling the phoma stem canker of rape. In addition, the phoma stem canker of rape is controlled by adopting the composition provided by the invention, under the condition of ensuring the controlling effect, the consumption of the carbendazim and the tebuconazole is reduced, and thus the potential pesticide resistance risk of leptosphaeria maculans to the carbendazim and the tebuconazole is lowered.

Description

Technical field [0001] The invention belongs to the field of pesticides, and specifically relates to a composition for preventing and treating rape stem ulcer. Background technique [0002] The chemical name of carbendazim is N-(2-benzimidazolyl)-methyl carbamate. It is a benzimidazole fungicide. The main antibacterial mechanism is through the inhibition of the mitosis process of the bacteria, which eventually leads to the death of the bacteria. Carbendazim has a good control effect on crop diseases caused by a variety of ascomycetes, basidiomycetes and deuteromycetes, and is widely used in the prevention and control of diseases in the storage of various crops and fruits and vegetables. [0003] Tebuconazole is an inhibitor of ergosterol biosynthesis of pathogenic bacteria. It acts on the interruption of ergosterol synthesis in phytopathogenic bacteria, and then exhibits a strong antibacterial effect. The medicament has a wide bactericidal spectrum, a long lasting period, has exce...

However, in recent years, as the number of imported rapeseeds in my country has increased year by year, the rapeseeds scattered around the port area and the refinery have caused the potential spread of rapeseed canker. Therefore, research and development of prevention and control agents for this quarantine disease, It is of great significance to establish a "firewall" for the safe production of rapeseed in our country
