Rice false smut is a common fungal disease in the late stage of rice. The diseased rice grains will consume the nutrients of the whole panicle, resulting in other grains not full, the 1000-grain weight is reduced, and the overall quality is greatly reduced. If you want to control rice false smut, you have to choose the right time for application. Rice false smut disease invades the grain 7 days before the rice break, that is, the rice leaf pillow is flat. After the rice blooms, the filaments wither and the pathogen no longer infects the rice. Therefore, the latest application period of rice false smut disease needs to be before the break heading and the medicament control cannot be effective after blooming.
Prevention and control methods:
1. Strengthen cultivation management: implement wide and narrow row planting to improve field ventilation and light transmission.
2, rice false smut control agents can be selected: hexaconazole, tebuconazole, fluoriconazole and other triazole fungicides. This kind of fungicide has a wide bactericidal spectrum, which not only has a good control effect on rice false smut, but also has a preventive effect on other diseases. The compound agent pyraclostrobin · fluoriconazole can also be selected, which is compounded by two different fungicides, and the control effect can be greatly increased after compounding.
