Abstract
The invention discloses a spirotetramat-containing pesticidal composition which contains an active component A and an active component B, wherein the active component A is selected from spirotetramat; the active component B is selected from dinotefuran or pyriproxyfen; and the weight ratio of the active component A to the active component B is 1:70-70:1. The composition disclosed by the invention can prevent and treat many soil pests, has an obvious synergistic action, widens the pesticidal spectrum, and has higher activity for coccid, sweetpotato whitefly, brown paddy plant hopper, whitebacked rice fulgorid, small brown rice planthopper, rice leafhopper, green plant bug and the like on vegetables, fruit trees, cotton and paddy rice; the invention reduces the consumption of the pesticide, lowers the residue level of the pesticide on crops, and reduces the environmental pollution; the composition is safe for both human and livestock, and has favorable environmental compatibility; and the pests can not easily generate drug resistance.
Description
technical field [0001] The invention belongs to the technical field of pesticides and relates to an insecticidal composition containing spirotetramat. Background technique [0002] Spirotetramat chemical name: 4-(ethoxycarbonyloxy)-8-methoxy-3-(2,5-xylyl)-1-azaspiro[4,5]- Dec-3-en-2-one, molecular formula: C 21 h 27 NO 5 , the new insecticide spirotetramat is a tetronic acid compound, which belongs to the same type of compound as the insecticide and acaricide spirodiclofen and spiromesifen of Bayer Company. Spirotetramat has unique action characteristics and is the only modern insecticide with two-way systemic conduction properties so far. The compound can move up and down throughout the plant to reach the foliage and bark, thereby controlling pests such as on the inner leaves of lettuce and cabbage, and on the bark of fruit trees. This unique systemic property protects young stems, leaves and roots from the growth of pest eggs and larvae. Another feature is its long-l...
