Abstract
The invention relates to a bactericidal and insecticidal composition and a method for preventing and treating crop diseases and insect pests. The bactericidal and insecticidal composition provided by the invention comprises a first active component and a second active component, wherein the first active component is 1-methyl-2-nitro-3-(tetrahydro-3-furfuryl)guanidine, the second active component is 5-(4-chlorophenyl)-2,2-dimethyl-1-(1,2,4-triazole-1-yl-methyl)cyclopentanol, and a weight ratio of the first active component to the second active component is 1: 100 to 100: 1. The bactericidal and insecticidal composition provided by the invention has insect-preventing, disease-preventing and gain effects instead of merely individual effects of the two active components.
Description
technical field [0001] The invention relates to a bactericidal and insecticidal composition, in particular to a method for preventing and controlling crop diseases and insect pests. Background technique [0002] Piercing-sucking mouthparts refer to some pests with piercing-sucking or file-sucking mouthparts, belonging to Homoptera, Hemiptera, Thysanoptera and Diptera, etc., mainly including leafhoppers, aphids Cicadas, cicadas, whiteflies, scales, stinkbugs, thrips, and gall midges, etc. These pests use the juice of plants as their food, and constantly carry out "blood-sucking and marrow extraction" to extract plant nutrients. . There is no obvious damage on the plant surface after eating, but spots or deformities of various colors often appear on the leaves, such as shrunken and curled leaves, galls and insect tumors formed on leaves, stems and roots. After the piercing-sucking mouthparts pest occurs, the damaged leaves turn from green to yellow and fall off, which affect...
