Problems solved by technology

[0009] Although there are many research reports on chlorantraniliprole for seed treatment to control pests, the control effect of its treatment on corn seeds against Spodoptera frugiperda has not been reported, and the research on its combined seed treatment with insecticidal fungi has not been reported.

Embodiment 1

[0025] The field test results showed that 1.33 grams of chlorantraniliprole active ingredient and 10 spores of Metarhizium anisopliae were used per kilogram of corn seeds. 11 For a seed dressing treatment, 15 days after sowing, the corn damage rate was 3.3%, and the damage rate of the control group in the same period was 40%, indicating that within 15 days after the seed dressing treatment, the occurrence of Spodoptera frugiperda can be effectively controlled and the ideal seedling preservation effect can be achieved.

Embodiment 2

[0027] The results of the field test showed that 0.67 grams of the active ingredient of chlorantraniliprole and 10 spores of Metarhizium anisopliae were used per kilogram of corn seeds. 10 A treatment group (low dose group) and chlorantraniliprole active ingredient 1.33 grams and Metarhizium anisopliae spores 10 11 Two treatment groups (high dose group), after sowing 30 days, the corn damage rate of high dose treatment group is 1%, the damage rate of corn of low dose treatment group is 2.9%, and the damage rate of contrast corn of the same period is 3.5%. Within 30 days, the occurrence of Spodoptera frugiperda can still be effectively controlled, achieving a certain effect of preserving seedlings.

Abstract

The invention discloses a method for preventing and controlling spodoptera frugiperda by using chlorantraniliprole and green muscardine fungus combined acorn seed treatment. Aiming at solving the serious problem of newly invading spodoptera frugiperda on corns in China, each kilogram of corn seeds is subjected to seed dressing treatment through 0.67-1.33g of active ingredients of the chlorantraniliprole and the 10<10> to 10<11> green muscardine fungus, and damage of pests such as the spodoptera frugiperda in a corn seedling stage can be effectively controlled. Compared with a current spodoptera frugiperda preventing and controlling method with a spraying method as the main, a seed treatment technology is more efficient, safer, and more convenient; and after a wide range of application, thepreventing and controlling effects on the invasive pests, namely the spodoptera frugiperda, can be practically improved, pressure of prevention and control is effectively relieved, and significant economic, ecological, and social benefits are achieved.

Description

[0001] 1. Technical field [0002] The invention belongs to the technical field of pest chemical control, and in particular relates to a method for treating pests such as Spodoptera frugiperda by using chlorantraniliprole and metarhizium anisopliae seed dressing to treat corn seeds. [0003] 2. Technical Background [0004] Spodoptera frugiperda belongs to Lepidoptera Noctuidae pests, native to tropical and subtropical regions of America. Flying pests. Spodoptera frugiperda has the characteristics of wide habitat area, strong migratory ability, miscellaneous feeding habits, heavy damage, and difficult control. Since it invaded my country in January 2019, the insect has spread rapidly to many provinces. As the spread of fall armyworm in my country is becoming more and more serious, the demand for new technology research on its prevention and control is also becoming more and more urgent. [0005] Spray control with chemical agents is currently the most common way to control fa...
