Hazardous features Bacterial leaf streak disease mainly affects the leaves. At the beginning of the lesion, there were dark green water-stained, translucent spots that gradually spread in the vein direction. When expanded, it is limited by veins. The lesions are thin lines or short-dashed lines and are brownish-brown. When the humidity in the field is large, the surface of the diseased area has honey-yellow fungus with pus overflowing, dew-like and densely dense. The number is much smaller than that of bacterial leaf blight, and after the dry knot, it is yellow gum-like small particles, shaped like a dotted line and not easy to fall off. When the disease is severe, the stripe fused into irregular tan to large white patches. The appearance is similar to that of bacterial leaf blight, but the lesions are translucent when observed with light. When the disease is prevalent, the leaves curl and become completely white. The disease is easy to infect before and after rice growth. The symptoms at seedling stage are more obvious than bacterial blight. When the disease is serious, it can cause early death of rice plants or failure of heading. Even if it is capable of heading and fruiting, the cereal grains increase and the grain weight decreases. Prevention and control methods Rice bacterial streak infection is fast. Once it occurs, it is often difficult to control by relying solely on chemical control. Therefore, comprehensive measures focusing on prevention should be adopted. 1. Strengthening plant quarantine It is forbidden to plant seeds from the ward to prevent the ward from expanding. 2. The selection of disease resistant varieties for agricultural control, appropriate application of phosphorus and potassium fertilizers, and the prevention of excessive and late application of nitrogen fertilizers to increase plant disease resistance. No string irrigation, no irrigation of deep water, and proper baking of the field. 3. Fungicides The current use of fungicides in production has little effect on the control of disease epidemics; drug control can only be used as an aid to disease prevention and production. 1 Soaking. The seeds are pre-soaked with fresh water for 12 to 24 hours, and then soaked for 12 to 24 hours with 300 to 500 times of 85% strong chlorine extract. 2 spray. A strong chlorine extract was sprayed on each seedling at the three-leaf stage and before the pullout. In heading stage of rice, use 20% Ye Qingshuang WP 100-125 g per mu, or 90% Daojing 125 g, or 10 million units agricultural streptomycin 10 g, or potassium permanganate 5 g plus appropriate salt. Spray 50 kg water, have a certain effect. According to the test results, Zhuhai Green South Fresh Foods Corporation developed and produced green copper copper fungicide green milk copper in recent years, which is a promising new pesticide species for controlling bacterial leaf streak in rice. During the epidemic period of disease, 100% of 12% green milk copper emulsion was used per acre, sprayed on water 500 times, and sprayed once every 10 days. After 20 days of application, the growth rate of the disease index in the green lactated copper treatment area was 5.06% to 10.96%, with an average of 7.85%. The control effect was 81.0% to 91.0% with an average of 85.0%. The growth rate of the disease index in the chlorothalonil treatment zone was 6.52% to 14.49% with an average of 11.71%, and the control effect was 62.8% to 88.4%, with an average of 76.6%. The growth rate of the disease index index in the control zone was 38.16% to 68.57% with an average of 54.39%.
