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] In the background of potato agar medium suitable for the growth of rice smut, adding the inhibitor of rice smut from ribose can easily detect the antibacterial effect of the inhibitor derived from ribose on rice smut. The specific operation is as follows:

[0015] 1. Prepare Potato Agar Premixed Medium P

[0016] The potato agar medium suitable for the growth and development of rice smut is used as the background medium, and the pre-mixed ratio of the background medium is: 200 g of potatoes, 40 g of agar, and 1000 ml of distilled water. Potato agar preformed medium P was obtained after conventional high-temperature sterilization.

[0017] 2. Preparation of ribose solution A and its high-temperature treatment product B

[0018] Proportion: 20 g of ribose and 1000 ml of distilled water are prepared into a ribose solution, and the ribose solution is filtered and sterilized with a bacterial filter at room temperature to obtain a ribose solution A that has not been subject...

Abstract

The invention discloses a ribose-derived Ustilaginoidea virens inhibitor which is derived from the compound ribose. The inhibitor is formed by carrying out high-temperature treatment on ribose. The ribose-derived Ustilaginoidea virens inhibitor has the effect of strongly inhibiting growth and development of Ustilaginoidea virens. The inhibitor can provide an effective feasible technical start and technical pathway for developing and researching drugs for preventing and treating Ustilaginoidea virens.

Description

technical field [0001] The present invention relates to plant pathology technology and pesticide science technology. Specifically, it is an inhibitor of rice smut fungus derived from ribose. 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...
