specific Embodiment approach 1

[0019] Embodiment 1: A botanical fungicide for preventing and treating potato dry rot according to this embodiment is an ABBA solution with a concentration of 0.1-2.0 mg / mL.

specific Embodiment approach 2

[0020] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that ABBA is extracted from Dryopteris crassirhizoma of Dryopteridaceae (Dryopteridaceae) genus Dryopteris Adanson of. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0021] Embodiment 3: This embodiment differs from Embodiment 1 in that it is ABBA with a concentration of 0.5-2.0 mg / mL. Others are the same as in the first embodiment.

Abstract

The invention relates to a botanical bactericide for preventing and treating potato dry rot and a preparation method thereof. The botanical bactericide solves the problem that the existing chemical bactericide causes the pathogen resistance to bactericides and environmental pollution after long-term use. The botanical bactericide is a solution of dryocrassine ABBA extracted from Dryopteris crassirhizoma Nakai and has a concentration of 0.1 to 2.0 mg / mL. The botanical bactericide is non-toxic, has no pollution, has high antibacterial activity and can produce strong inhibition effects on growth of potato dry rot main pathogens such as Fusarium culmorum, Fusarium oxysporum, Fusarium sambucinum and Fusarium solani var.coeruleum (Sacc.) Booth, can effectively inhibit the radial growth of hyphae and can significantly reduce a hypha growth rate. The botanical bactericide for treating potato tubers can improve the resistance of tubers to dry rot, can inhibit the fusarium infection of tubers, and does not cause damage to tubers.

Description

technical field [0001] The present invention relates to the field of plant protection. Background technique [0002] Potato dry rot is a fungal disease caused by Fusarium spp. It is one of the main diseases during potato storage. The loss rate is about 15%-35%, and it can reach 50% in severe cases. At present, chemical agents are mainly used for prevention and control, and good results have been received. However, after long-term use of chemical agents, pathogenic bacteria tend to develop drug resistance, causing the frequency of disease resistance in most areas to exceed 50%, and the control effect decreases year by year. Lost defense effect. At the same time, because the use of a large number of pesticides has seriously polluted the ecological environment such as soil and water bodies, it is urgent to research and develop high-efficiency, low-toxicity, low-residue, and environmentally friendly botanical fungicides. Contents of the invention [0003] The purpose of the ...
