Abstract

The invention provides an application of C21 steroid compounds 1-8 separated from cynanchum paniculatum in preparation of anti-TSWV (tomato spotted wilt virus) active products. Tests prove that the C21 steroid compounds 1-8 in cynanchum paniculatum have anti-TSWV activity, and show different degrees of prevention effects on TSWV. Specifically, the invention also provides an application of the C21steroid compounds 1-8 of cynanchum paniculatum in preparation of a TSWV inhibitor. When the concentrations of the compound 4 and the compound 5 are 100 [mu]g / mL, the virus content is less than that ofningnanmycin, which indicates that the prevention effect on TSWV is superior to that of commercially available antiviral pesticide ningnanmycin.

Description

technical field

[0001] The invention belongs to the field of biopesticides, in particular to C 21 Steroidal compounds 1-8 are used as preparations for the prevention and control of TSWV in the preparation of anti-TSWV active products. Background technique

[0002] Tomato spotted wilt virus (TSWV) is a representative species of the genus Tospovirus in the family Bunyaviridae. Its host range is very wide, and many important economic crops (such as tobacco, pepper, Tomato) are susceptible to infection and cause serious economic losses, so it is listed as one of the top ten plant viruses in the world. At present, the prevention and control of viral diseases in production is mainly through insect control and disease prevention, but its transmission vectors are prone to produce resistance, and crops are prone to problems such as excessive pesticide residues. In addition, there is a lack of disease-resistant varieties, and there is still a lack of effective prevention and control ...
