Embodiment Construction

[0022] Combined toxicity of spirotetramat and chlorfenapyr in different ratios

[0023] 1.1 Test agents

[0024] 95% Spirotetramat original drug, 94.5% Chlorfenapyr original drug, the above-mentioned original drugs are provided by Qingdao Hailier Pharmaceutical Co., Ltd. R&D center.

[0025] 1.2 Test source

[0026] Indoor potted apple seedlings are continuously reared for 10 generations of third-instar adults of apple aphids, temperature (25 ± 2) o C, the relative humidity is 50%±4%, and the photoperiod is 14 / 1 0 h (L / D).

[0027] 1.3 Single-dose determination method

[0028] The two original drugs were dissolved with a small amount of acetone by using the method of soaking insects, and then diluted with a 0.1% Tween aqueous solution into 5 aliquots of concentrated solutions, which were diluted in a beaker for later use, and clean water was used as a control. The third-instar apple aphid adults of the same size were immersed in the insect cage for 5S, and the excess liquid was suck...

Abstract

The invention relates to a pesticide insecticidal composition, which takes spirotetramat and chlorfenapyr as the effective components. Specifically, spirotetramat and chlorfenapyr are in a mass percentage of 1-80:80-1, and the content of spirotetramat and chlorfenapyr in the compound preparation is 1-80%. The compound pesticide composition provided by the invention can be prepared into missible oil, suspending agents, wettable powder, water dispersible granules, emulsions in water and other dosage forms by methods well known to technicians in the field. The insecticidal composition provided by the invention is suitable for controlling piercing-sucking mouthpart pests in vegetables and fruits, and is especially suitable for controlling aphids, whiteflies, mealybugs, scale insects, plant hoppers, thrips, and Empoasca pirisuga Matumura, etc.

Description

Technical field [0001] The present invention involves a pesticide pesticide combination with an efficiency, and the effective ingredients are snails ethyl and bromine. Background technique [0002] Aphids, livelings, thrips, garages, and barrier -sucking mouthpieces have the characteristics of short breeding cycle, large breeding volume, and obvious generations of generations, which are easy to produce resistance.Due to a large number of years of use, the above -mentioned pests have severely resistant to pests such as pormpevaclopoline, mimetrics, and other agents. [0003] Stecope ethyl, English name SPIROTETRAMAT, is a metharocytone pesticide developed by Bayer. It belongs to similar compounds with pesticides and pipe threaded pipes.Stecope ethyl has a unique characteristics and has excellent two -way internal suction conduction performance. It can move upwards in the entire plant and reach the leaf surface and bark.Roots to prevent the growth of the pests and larvae.Another ch...
