Problems solved by technology

[0003] Spodoptera frugiperda, belonging to the family Noctuidae of Lepidoptera, has strong fecundity and environmental adaptability, and it is easy to develop resistance to various types of insecticides. The resistance to formamide and cyantraniliprole develops slowly. However, when such insecticides are used for seed treatment, the effect is slow, and effective control cannot be carried out in the early stage of crop growth. When made into granules, the drugs are easily degraded. Lead to poor drug efficacy, it is difficult to play a preventive role, in order to solve the above technical problems, a new technical solution is proposed

Abstract

The invention relates to a pesticide for preventing and treating grassland spodoptera litura, and relates to a pesticide. The pesticide comprises an attractant, an adjuvant, beer yeast powder, composite vitamin powder, glucose and active metarhizium anisopliae. The pesticide is prepared from the following components in parts by weight: 1-10 parts of an attractant, 2-30 parts of an adjuvant, 1-10 parts of beer yeast powder, 1-15 parts of compound vitamin powder, 1-5 parts of glucose and 40-70 parts of active metarhizium anisopliae. The pesticide has the advantages that the resistance development of the grassland spodoptera litura can be effectively slowed down, the effect of the cyantraniliprole in seed treatment is achieved quickly, the pesticide effect is stable, an excellent prevention and control effect on pests is achieved, and the pest resistance of crops is improved.

Description

Technical field: [0001] The invention relates to a pesticide medicament, in particular to a pesticide medicament for controlling Spodoptera frugiperda and a preparation method thereof. Background technique: [0002] Spodoptera frugiperda (scientific name: Spodoptera frugiperda): is a moth of the genus Spodoptera frugiperda. Adults are nocturnal and lay about 100 eggs on top of plant leaves. The egg stage lasts for 3 days at a temperature of 25°C. Newly hatched larvae feed on the egg shell itself, which then sits for 2-10 hours. The larvae, the caterpillars, prefer to feed on new leaves and will usually each find a new leaf due to their feeding habits. The larvae change skin seven times and exit the ink sac the last time, penetrating 0.5 cm of soil, where they become pupae. The pupal stage lasts about 10-12 days during the hottest period of the year. The lifespan of adults is about 12 days, and the complete cycle of this pest is only 30 days.
