Ectropis grisescens warreh nuclear polyhedrosis virus bakthane insect disinfestation suspension agent and preparation method thereof

Abstract

The invention discloses an ectropic obliqua nuclear polyhedrosis virus bacillus thuringiensis desinsection suspending agent and a preparation method thereof. The agent mainly comprises the ectropic obliqua nuclear polyhedrosis virus and the bacillus thuringiensis, wherein the content of the inclusion body of the ectropic obliqua nuclear polyhedrosis virus is (1.0x10<6>-1.0x10<10>)PIB/mL, and the content of the bacillus thuringiensis is between 3.0 and 25.0 percent. The ectropic obliqua nuclear polyhedrosis virus bacillus thuringiensis desinsection suspending agent comprises the ectropic obliqua nuclear polyhedrosis virus, the bacillus thuringiensis, polycarboxylate, sodium lignosulfonate, dioctyl sulfo succinic acid, alkyl sulfonate, white carbon black, magnesium aluminum silicatenf, sodium benzoate, xanthan gum, carboxymethyl cellulose, polyvinyl alcohol, glycol, propanediol, organosilicon defoamer and water which are mixed according to certain ratio. The agent and the preparation method thereof are not harmful to environment, organisms and human bodies, do not pollute the environment or have residue, and can effectively control the generation and harm of the ectropic obliqua; and the agent is suitable for the application in a large quantity, has long persistent period, increases the speed of the virus to kill pests, and ensures that the desinsection time of the virus pesticide is shortened to three to five days.

Description

technical field [0001] The invention relates to biological insecticides, more specifically to a tea geometrid nucleopolyhedrosis virus Bacillus thuringiensis insecticidal suspension, which is suitable for preventing and controlling tea garden Lepidoptera pests such as tea geometrids, tea moths, leaf tortrixes and tea caterpillars. It also relates to a method for preparing the tea geometrid nucleopolyhedrosis virus Bacillus thuringiensis insecticidal suspension. Background technique [0002] Tea geometrid, Lepidoptera, geometrid mothidae; aliases large geometrid, measuring geometrid, tung geometrid, wood stick insect, kabud, etc.; mainly include tung geometrid, silver geometrid, gray geometrid, camellia oleifera, among them Tung inchworm occurs the most; it is mainly distributed in Anhui, Jiangsu, Zhejiang, Jiangxi, Hubei, Hunan, Sichuan, Guizhou, Guangdong, Guangxi, Fujian and other provinces. [0003] Tea inchworm is one of the main pests of tea trees in my country. The d...
