Abstract

The invention belongs to the field of agricultural pesticides, and particularly relates to tebufenpyrad/metaflumizone wettable powder and a production method thereof. The wettable powder comprises the following effective ingredients in percentage by weight: 10-80% of tebufenpyrad and metaflumizone, wherein the tebufenpyrad/metaflumizone weight ratio is (10:1)-(1:10), and the preferable ratio is 1:(1-3). The composition provided by the invention is mainly used for controlling mites, lepidoptera pests, aphides, whiteflies and the like on fruit trees, vegetables and grain crops. The composition has the characteristics of effect improvement, pesticidal range widening, pest drug resistance delaying, high crop safety and the like.

Description

technical field [0001] The invention belongs to the field of agricultural insecticides, in particular to a wettable powder of tebufenpyrad and metaflumizone and a production method thereof. Background technique [0002] Tebufenpyramid is an amide acaricide. It has excellent effects on various mites and pests of Hemiptera and Homoptera, and has quick-acting and high-efficiency effects on all growth stages of mites, and has a long-lasting effect, such as Tetranychidae (Planyonychus apple, Panonychus citrus, cotton Tetranychus, Tetranychus cinnabarinidae, etc.), Tarsidae (lateral tarsal mites), Eriodidae (apple rust mite, grape rust mite, etc.), Styropterygidae (Grape mite), Aphididae ( peach aphid, cotton aphid, apple aphid), whitefly family (cassava whitefly). No cross-resistance with dicofol, fenbutatin, thiazofen, etc. No systemic, but osmotic activity, excellent selectivity to the target crops, no phytotoxicity to most crops under the recommended dose (25-200mg(a.i....
