Abstract

The invention provides a pesticide resistant to a tobacco mosaic virus and belongs to the technical field of pesticides. The pesticide resistant to the tobacco mosaic virus is prepared from the following raw materials including, by weight, 10-30 parts of sophora flavescens, 10-30 parts of semen aesculi, 10-30 parts of mugwort, 5-20 parts of litchi hulls, 5-20 parts of lemon peels, 5-20 parts of loofah peels, 5-15 parts of cinnamomum camphora leaves, 3-12 parts of rosemary, 3-12 parts of forsythia suspense, 3-12 parts of acorus calamus and 1-5 parts of biopreparate. The biopreparate is composed of, by mass, 1-10% of bacillus thuringiensis, 30-40% of streptomyces microflavus and 50-60% of photosynthetic bacteria. The materials of the pesticide are environmentally friendly, the pesticide is harmless to tobacco and plants and capable of efficiently killing the tobacco mosaic virus, the virus resistant rate reaches 90% or above, and the pesticide resistance is avoided during long-time using.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide against tobacco mosaic virus and a preparation method thereof. Background technique [0002] Tobacco mosaic virus (TMV) is a plant virus that seriously harms tobacco production. After tobacco is infected with this virus, the lateral veins and branch veins of young leaves become translucent, and the mesophyll tissue on both sides of the veins gradually turns light green. The virus multiplies in a large amount in the leaf tissue, causing some mesophyll cells to increase or increase, resulting in uneven thickness of the leaves, yellow and green in color, and a mosaic shape. The mottled degree of the back mosaic leaves increases, and large areas of dark brown necrotic spots appear, especially in the middle and lower parts of the old leaves. The severely affected leaves are shrunken, deformed, and twisted. The internodes of plants with early onset are short...
