The continuous rainy weather since July is conducive to the occurrence of bacterial diseases in rice. According to the survey, on July 22, in the Mingzuling Town of You County, rice bacterial streak disease was seen. As of August 2, the old wards of Huanghuatang, Mudian, Tiefo, and other towns and villages were successively sick, and the area was about 200 acres. The main hazard is two-line hybrid japonica rice, with a high rate of 60%.

Recent frequent thunderstorms are conducive to the occurrence and epidemic of bacterial leaf streak in rice and should be fully controlled once. Use 20% Bacillus thuringiensis copper suspension 100-150 ml per mu, or 20% Yezizole wettable powder 100-150 g, or 36% trichloroisocyanuric acid wettable powder 60-90 g, add water 30 Kilogram spray. The already affected fields should be controlled once every 5 to 7 days. After treatment, the storms should be remedied and remedy 1 or 2 times to improve the control effect. We often observe the occurrence of old sick fields in the old wards, especially the serious sick fields, and find that sporadic diseased leaves or disease centers immediately block the protection with drugs. When spraying, pay attention to the area that has not been infected before spraying, gradually surround the center of the disease, and the center of the disease should focus on spraying. Followed the principle of early treatment and drug protection in the prevention and control strategy. It was found that one piece was hit and one piece was found.

In addition to chemical control, special protective measures should be taken for paddy fields with bacterial streak disease, which prohibits string irrigation, flood irrigation, and the use of recycled water to prevent the spread of diseases.
