Medicament composition for preventing and treating grassland spodoptera litura

Abstract

The invention discloses a medicament composition for preventing and treating grassland spodoptera litura. The medicament composition comprises auxiliary materials, an effective component A and an effective component B, wherein the effective component A is tea saponin, the effective component B is chlorantraniliprole or tolfenpyrad, and the mass ratio of the effective component A to the effective component B is (1-20): (20-1). The tea saponin and the chlorantraniliprole or tolfenpyrad are mixed to prepare an insecticide with a certain proportion, the insecticide is used for preventing and treating the grassland spodoptera litura, the effect is good, the dosage is low, and the resistance of the grassland spodoptera litura to the insecticide can be well delayed.

Description

technical field [0001] The invention belongs to the technical field of pest chemical control, in particular to a medicament composition for controlling Spodoptera frugiperda. Background technique [0002] Spodoptera frugiperda belongs to Lepidoptera, Noctuidae, commonly known as Fall Armyworm, Spodoptera frugiperda, and Pseudo-armyworm. Its larvae can eat a large number of crops such as corn and rice. Native to the tropical regions of the Americas, it has a strong ability to migrate. The larvae eating the leaves can cause leaf fall, and then the damage is transferred to other parts. Sometimes the larvae damage by cutting the roots, biting off the seedlings and plant stems, resulting in lack of seedlings. Ridges, in severe cases, cause more than 80% crop yield reduction, and have invaded most provinces in my country. If no reasonable and effective control of Spodoptera frugiperda is carried out, the affected area of ​​crops in my country will be further expanded. [0003] Chl...

Problems solved by technology

Native to the tropical regions of the Americas, it has a strong ability to migrate. The larvae eating the leaves can cause leaf fall, and then the damage is transferred to other parts. Sometimes the larvae damage by cutting the roots, biting off the seedlings and plant stems, resulting in lack of seedlings. Ridges, in severe cases, cause more than 80% crop yield reduction, and have invaded most provinces in my country. If no reasonable and effective control of fall armyworm, the affected area of ​​crops in my country will further expand

[0003] Chlorantraniliprole, commonly known as Kangkuan, has been used to control Lepidoptera pests such as the rice borer and the rice leaf roller. The resistance to insecticides is becoming more and more serious, and the effect of controlling fall armyworm is also good, but we still need to be vigilant against the emergence of resistance
