Application of normalized prevention and control technology of rice bacterial leaf blight
Rice bacterial leaf blight is an important disease in the process of rice production,though we have done a lot of work in the prevention and control of this disease,but since 2015,the disease has been on the rise,especially after 2019,the occurrence area of rice bacterial leaf blight in Qujiang District has shown a multi-point and explosive growth,especially for single-season late rice and continuous cropping late rice,which poses a serious threat to rice production in our region.In this paper,we drew on the theory of"traditional Chinese medicine to treat diseases"and explored the use of the"3+X"model to prevent and control rice bacterial leaf blight.The results showed that compared with the conventional control methods,the early preventive treatment with 20%thiazolezinc in the key link of rice planting could not only effectively reduce the occurrence of diseases,delay the expansion rate of diseases in the field,but also improve the growth function of rice plants,and the crop safety was good.The prevention and control effect of this model reached more than 85%,and the yield increased by more than 10%compared with the conventional control area.
