Abstract

The invention relates to a miticide combination and application thereof. The mite-killing combination contains such active ingredients as bifenazate and tebufenpyrad in a mass portion ratio of 100:1-1:50 and can be prepared into micro-emulsion, wettable powders, water dispersible granules, suspending agent, aqueous emulsion or emulsifiable concentrates. The mite-killing combination has good synergistic effects, can retard the drug fastness of pests and prolong the service life of pesticide varieties. The combination is applied to controlling various mites on the cash crops, oil crops and foodcrops, is especially suitable for controlling panonychus ulmi, tetranychus urticae koch, tetranychus cinnabarinus, tetranychus truncates, polyphagotarsonemus latus and rust mites, and has the effect sobviously higher than the effects of the single two drugs.

Description

technical field [0001] The invention relates to an acaricidal composition, in particular to an acaricidal composition containing tebufenpyrad as an active ingredient and its application in the control of crop pest mites. Background technique [0002] There are many generations of harmful mites and strong reproductive ability. Under suitable temperature and humidity conditions, the number of harmful mites can rapidly double in a short period of time, so it is easy to develop resistance to acaricides. serious damage to crops. In order to prevent and control various harmful mites that are becoming more and more serious, countries all over the world are constantly developing new acaricides. In the development and application of acaricides, delaying the resistance or cross-resistance of harmful mites is the key factor to prolong the service life of products. Use acaricides rationally, control the frequency of use and dosage, and use acaricides with different mechanisms of action...
