Description

Technical Field

[0001] The present invention belongs to the field of pesticides and relates to a pesticidal and bactericidal composition containing clothianidin and tetrachlorantraniliprole and its application. Background Art

[0002] Clothianidin is a pyrazole carboxamide insecticide and belongs to a cymbal modulator (site of action unknown). Clothianidin has good systemic conductivity and is mainly used for controlling Lepidoptera, Hemiptera, Thysanoptera pests, etc. on cotton, such as vegetables, soybeans, cotton, potatoes, cereal field crops, etc., and is particularly effective against piercing-sucking mouthpart pests such as aphids, whiteflies, and psyllids.

[0003] Tetrachlorantraniliprole belongs to the anthranilic diamide ryanodine receptor modulator, has systemic conductivity, shows high activity against Lepidoptera pests, and has certain control effects on piercing-sucking mouthpart pests such as aphids and Coleoptera pests, and can be used for pest control of various crops.

[0004] Common diseases and pests of field crops such as peanuts and potatoes include root rot, leaf spot, stem rot, damping-off, aphids, grubs, black cutworms, wireworms, etc. The diseases and pests often occur in multiple types, and the time and location are inconsistent, making it difficult to control. Usually, multiple pesticide applications are required, which is time-consuming and laborious and difficult to completely control. Therefore, a drug that can kill insects and bacteria and has a long validity period and a friendly usage method is needed to solve this problem. Summary of the Invention
