Embodiment Construction

[0012] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0013] The invention provides a technical scheme: the application of a rhodopseudomonas palustris bacterial agent in the prevention and control of rice false smut cultivated.

[0014] The object of the disease is rice false smut, and the application method of the rhodopseudomonas palustris bacteria agent in the prevention and control of rice false smut is: spraying the rhodopseudomonas palustris bacteria agent on the tillering stage and the breaching stage of rice.

[0015] The bacterial concentration of Rhodopseudomonas palustris was 5×10 9 cfu / mL, the spraying amount is 120ml per mu, diluted 500 times with water, and sprayed once at the tillering stage and the breaching stage.

[0016] As an embodiment of the present invention: the biocontrol...

Abstract

The invention provides application of a Rhodopseudomonas palustris microbial agent in prevention and control of false smut. A disease object is rice false smut, and a method of application of the Rhodopseudomonas palustris microbial agent in the prevention and control of the false smut comprises the step of spraying the Rhodopseudomonas palustris microbial agent to rice at a tillering stage and arupturing stage. Compared with the prior art, the application has the following beneficial effects that the Rhodopseudomonas palustris microbial agent contains an excretion protein and a metabolite, thereby being capable of effectively preventing and treating the false smut; and the Rhodopseudomonas palustris microbial agent has the characteristics of being environmentally friendly, being non-toxic to human and animals, being free of pesticide toxicity to crops, being simple and convenient to apply, and the like.

Description

technical field [0001] The invention relates to the technical field of biological pesticides, in particular to the application of a novel microbial agent (Rhodopseudomonas palustris agent) in the prevention and control of rice false smut. Background technique [0002] In recent years, with the promotion of high-yield hybrid rice, especially super rice, and the improvement of water and fertilizer levels, rice false smut has become one of the most serious diseases in major rice producing areas in my country. Rice false smut is caused by the infection of rice florets by the rice false smut fungus (Villosiclavavirens). Rice false smut not only causes serious reduction in rice production, but more importantly, rice smut contains high concentrations of toxins, which can inhibit the assembly of tubulin in animal cells and cell mitosis, and are highly toxic to humans and animals. For the prevention and control of rice false smut, chemical control is still the main method at present...
