Problems solved by technology

[0005] Thiantamid and spinosad are costly when used alone, which limits their popularization and application to a certain extent, and long-term single use is likely to increase the degree of pest resistance
[0006] However, there are still some technical defects in these existing technologies, which cannot meet the needs of current agricultural production. Therefore, it is necessary to develop new high-efficiency insecticidal compositions, which is of great significance for promoting the development of large-scale agriculture.

Abstract

The invention relates to pesticide composition containing thiotraniliprole and pleocidin. The thiotraniliprole and the pleocidin are mixed according to a weight ratio of (1-30) to (1-60), so that a remarkable synergistic effect is achieved. The pesticide composition and a pesticide are suitable for preventing and controlling crops beet armyworm, plutella xylostella, cabbage caterpillar, thrips, peach fruit moth, aphid, rice leaf folder or cotton bollworm. The pesticide composition is superior to a mono-agent in fast-acting property and persistence; and the pesticide dosage and cost are reduced, thereby facilitating environmental protection and comprehensive control of agricultural pests.

Description

【Technical field】 [0001] The invention belongs to the technical field of pesticides. More specifically, the present invention relates to an insecticidal composition containing thiatran and spinosyn, and also relates to the use of the insecticidal composition. 【Background technique】 [0002] In the practice of agricultural production, we often face the phenomenon of mixed occurrence of multiple pests on one crop. For example, when rice plants are damaged by rice planthoppers, they are often accompanied by mixed damage from rice leaf rollers, rice stem borers, and rice stem borers. Whiteflies, aphids and diamondback moths, Spodoptera litura, and Beet Spodoptera often occur mixedly. For this reason, people often will repeatedly apply pesticides and just can reach control multiple pest. Therefore, there is an urgent need in production for pesticide products that can control multiple pests at one time, so as to reduce agricultural costs. [0003] Thiamidamide insecticides have...
