Abstract

The invention relates to an insecticidal composition containing sulfamide (HY366) and tolfenpxrad and an application thereof. The sulfamide and tolfenpxrad are mixed in a weight ratio of (1-50):(1-50) to realize a remarkable synergistic effect for controlling empoasca pirisuga matumura; after 10 days of application of the 10-60% HY366.tolfenpxrad preparation, the control effect on empoasca pirisuga matumura reaches 88.4-91.2%; after 20 days of application, the control effect reaches 87.4-91.5%; and thus, the control effect is much higher than that of a single dosage of HY366 and tolfenpxrad. The insecticidal composition provided by the invention can effectively control lepidoptera pests of rice and vegetables.

Description

【Technical field】 [0001] The invention belongs to the technical field of pesticides. More specifically, the present invention relates to an insecticidal composition containing thiatiliprole and tolfenpyrad, and also relates to the use of the insecticidal composition. 【Background technique】 [0002] Tea little green leafhopper (Empoascapirisuga Matumura), Homoptera, leafhopper family Cicadellidae, commonly known as floating dust, leaf collembola, etc., occurs in all tea-producing provinces and autonomous regions across the country, and is one of the main tea pests. This worm occurs about 8-12 generations a year, and the generations alternate. Seriously damage summer and autumn tea. The buds and leaves of the affected tea trees are curled up, hardened, the tip and leaf edge are reddish brown and scorched, and the buds grow slowly, which has a great impact on the yield and quality of tea. Moreover, with the continuous application of chemical agents, the problem of pesticide r...
