Abstract

A disclosed biological bactericide for controlling paddy rice diseases employs cinnamon essential oil as the active component. Specifically, the biological bactericide is composed of cinnamon essential oil, a surfactant, a co-emulsifier and water, and per Kg of the biological bactericide contains 0.75-75000 mg of cinnamon essential oil, 1.75-175000 mg of the surfactant, 0.75-75000 mg of the co-emulsifier and the balance water. The biological bactericide is mainly used for controlling xanthomonas oryzae pv.oryzae.

Description

technical field [0001] The invention belongs to the technical field of rice disease prevention and control, and in particular relates to a biological fungicide for rice disease in the field of biological control. Background technique [0002] In recent years, my country's total rice output has been in a steady growth trend. As the country with the largest rice output, the prevention and control of rice diseases is particularly important. There are many diseases of rice, among which bacterial blight may occur in every period of rice growth. Rice bacterial blight was first discovered in Japan at the end of the 19th century, and has become an important disease in Asian rice regions. my country's East China, Central China, and South China rice areas have serious occurrences, and it is also distributed in some rice areas in Northwest, Southwest, North China, and Northeast China, and it is also found in Tibet. [0003] At present, the disease can only be prevented and controlled...
