Problems solved by technology

In fact, limited to the superficial understanding of the biology of rice false smut, the current research and development of drugs for the prevention and treatment of rice false smut is almost limited to the direct borrowing of pesticides on the market or the compound application of existing drugs, and the research and development of source drugs for the control of rice false smut is very rare.

Embodiment

[0014] The high-temperature treatment product of the potato-xylose mixture is prepared into a medium plate, and the antibacterial effect of the inhibitory substances derived from the potato-xylose mixture on the rice smut can be easily detected. The specific implementation is as follows:

[0015] 1. Preparation of potato xylose control medium CK

[0016] With filter sterilized xylose solution, mix with potato agar medium and be in a ratio of: potato 100g, xylose 10g, agar 20g, water 1000ml potato xylose agar medium as CK control medium, pour culture plate.

[0017] 2. Preparation of Inhibitor Medium

[0018] Prepare a potato-xylose mixture according to the ratio: 200g of potatoes, 20g of xylose, and 1000ml of water, and then place the mixture in an ordinary high-pressure high-temperature sterilizer, heat it at 126°C for 30 minutes, and obtain a potato-xylose mixture after cooling The high-temperature treatment product (this product contains the active ingredient that inhibit...

Abstract

The invention discloses an ustilaginoidea virens inhibitor derived from a potato-xylose mixture. The inhibitor is derived from a mixture of potato and a compound xylose, and is generated by high-temperature processing the potato-xylose mixture, and the inhibitor has a function of efficiently inhibiting ustilaginoidea virens growth and development. The ustilaginoidea virens inhibitor derived from the potato-xylose mixture has the beneficial effect of providing an effective and feasible technological beginning and technological means for developing ustilaginoidea virens prevention and cure drugs.

Description

technical field [0001] The present invention relates to plant pathology technology and pesticide science technology. Specifically, a rice smut inhibitor derived from a potato-xylose mixture. technical background [0002] Rice false smut caused by Ustilaginoideavirens (Cooke) Takahashi occurs globally and is a major disease of rice production in my country. In some rice areas, rice false smut even exceeds rice blast to become a major disease of rice production. Due to the lack of adequate understanding of the law of plant disease disasters, the prevention and control of plant diseases still mainly depends on the control of drugs (pesticides) at present and for a long time to come. The same is true for the control of rice false smut. Therefore, the research and development of rice false smut prevention and control medicine just become the important technical work of solving the rice false smut problem. [0003] In history, rice false smut has always been a minor disease with...
