Rice false smut, alias green powder disease, pseudo smut, is a fungal disease. With the promotion of some short-bar compact rice varieties and the improvement of fertilization levels, the disease has become more and more prominent. The emptying rate of the diseased ear is significantly increased. After the onset, the yield can be reduced by 5%~10%. The rice false smut occurs mainly during the heading and flowering period, which damages the grain of the upper part of the ear, and rarely 1-2 grains per ear, up to 20 -30 capsules.

Control methods: Pharmacy prevention, the key period for rice field control of rice smut is rice late stage (breaking period of 3 to 5 days). When the susceptible variety encounters rainy weather at the heading stage, it will be applied again in the middle of the rice break (about 50% of the rice break), and the control effect at the heading stage is poor, and the application is not repeated. Applicable agents with organic phosphorus fungicides (such as Fengdeng rice koji, 瘟曲克星) have the best effect, Jinggangmycin also has certain control effect. Linyi Fertilizer Network Copyright
