Problems solved by technology

At present, the main methods of prevention and control are planting disease-resistant varieties, raising non-toxic seedlings, and cutting off transmission routes. Due to the large number of natural populations of TMV and their strong stress resistance and infectivity, conventional control methods are not effective. , high cost of prevention

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Serratia marcescens (Serratia marcescens) 2A2, the bacterial strain was preserved in the General Microbiology Center of China Microbiological Culture Collection Management Committee on September 7, 2011, and the strain preservation number is CGMCC No.5230. The laboratory screened a bacterial strain that can produce red pigment from the rhizosphere soil of Solanaceae crops in Jimo, Qingdao.

[0029] The process of extracting anti-TMV tripyrrole ring compounds from Serratia marcescens (Serratia marcescens) 2A2 is as follows:

[0030] (1) Crude extraction of secondary metabolites

[0031] 20L of Serratia marcescens 2A2 in LB culture medium [LB culture medium: in 950ml of deionized water, add: 10g of tryptone, 5g of yeast extr...

Abstract

The invention relates to anti-TMV (Tobacco Mosaic Virus) tripyrrole ring compound and a preparation method and application of the compound. The compound provided by the invention is a biological agent and particularly is a biocontrol agent especially developed for TMV, and the compound is completely free of a series of problems caused by application of chemical pesticides, which is beneficial to the pollution-free production of agricultural products.The compound provided by the invention can passivate TMV so that TMV loses infection activity. The compound also can induce the host to produce systemic resistance to alleviate and weaken the expression and occurrence of symptoms of TMV infected plants and the resistance effect on TMV is higher than 70%.

Description

technical field [0001] The invention relates to the field of plant virus pollution-free technology, in particular to an anti-TMV tripyrrole ring compound and a preparation method thereof. Background technique [0002] The plant virus disease caused by tobacco mosaic virus (Tobacco mosaic virus, TMV) infection is one of the most serious diseases on crops in my country. Crop growth caused serious losses. For a long time, the prevention and treatment of viral diseases in production has been dominated by chemical control. Although many antiviral chemical agents have begun to enter the practical stage, the control effect is very limited. [0003] TMV has a wide range of hosts and can infect 199 species of plants in 30 species. It has serious occurrence and damage in agricultural planting areas in my country. TMV is very virulent and stress-resistant, and the fresh juice containing the virus is still pathogenic when diluted to 1 million times. The inactivation temperature of the ...
