Abstract

The invention belongs to the technical field of biocide containing microbial fungi, and more specifically relates to a Metarhizium and bacterium composite pesticide used for killing Spodoptera frugiperda. The Metarhizium and bacterium composite pesticide comprises Metarhizium and bacteria, and possesses excellent prevention and control effect on Spodoptera frugiperda.

Description

technical field [0001] The invention belongs to the technical field of biocides containing microbial fungi, and in particular relates to a medicament for killing Spodoptera frugiperda compounded by Metarhizium anisopliae and bacteria. Background technique [0002] Spodoptera frugiperda, also known as pseudo armyworm, fall armyworm, fall armyworm, and lawn armyworm, belongs to the class Insecta, subclass Pteroptera, order Lepidoptera, family Noctuidae, and the genus Spodoptera frugiperda. moth species. Fall armyworm is native to the tropical and subtropical regions of America, widely distributed in the American continent, and damages a variety of crops ("Beware of the dangerous pest Fall armyworm invading my country", Guo Jingfei et al., Plant Protection, Vol. 44, No. 6, 2018 Issue, lines 1-5 of the first paragraph of the left column on page 1, published on December 31, 2018). It was confirmed on January 13, 2019 that Fall Armyworm invaded Yunnan Province of my country. As o...
