Abstract

The invention provides a rhodopseudomonas palustris strain. The rhodopseudomonas palustris strain is rhodopseudomonas palustris LY-6 and is preserved in the China Center for Type Culture Collection, and the preservation number is CCTCC NO:M2014525. The rhodopseudomonas palustris LY-6 is simple in production process, short in culture time and low in cost. The strain can be prepared into a biocontrol fungicide through a simple, quick and low-cost operation method, can effectively prevent bacterial streak diseases, and has the advantages of being environmentally friendly, free of harm to people and livestock, free of pesticide hazards on crops, easy and convenient to apply, low in cost and the like.

Description

Technical field [0001] The invention relates to the technical field of biological pesticides, in particular to the application of a new type of microbial agent (Rhodopseudomonas palustris) in the prevention and control of bacterial leaf streak. Background technique [0002] Rice bacterial leaf streak is caused by Xanthomonas oryzaepv.oryzicola, and is an important quarantine bacterial disease in rice production. Bacterial leaf streak of rice mainly damages rice leaves. Pathogens invade rice cells through stomata. At the initial stage of the disease, the diseased spots are dark green and translucent and water-stained, and then expand along the veins of the leaves to form streak symptoms. The occurrence of the disease has the characteristics of epidemic, explosive, and devastating. Once it occurs, it will reduce the rice yield by 5%-20%, and in severe cases, it will reduce the yield by more than 50%, which seriously threatens the safety of rice production. [0003] At this stage, th...
