Embodiment 1

[0022] Measured toxicity index (ATI) = (standard drug LC 50 / Test agent LC 50 )×100

[0023] Theoretical toxicity index (TTI) = A drug ATI × the percentage of A in the mixture + B drug ATI × the percentage of B in the mixture

[0024] Co-toxicity coefficient (CTC) = (mixture ATI / mixture TTI) × 100

[0025] When CTC≤80, the composition exhibits antagonistic effect, when 80

[0026] The test results are shown in Table 1.

[0028]

[0029]

[0030] It can be seen from Table 1 that when the weight ratio of fenflumet and bifenazate is mixed between 50:1 and 1:50, the co-toxicity coefficients of each proportion have reached more than 120, showing a certain synergistic effect ; When the weight ratio of cyflumet and bifenazate is mixed between 1...

Abstract

The invention relates to an acaricidal pesticide composition. The active compositions of the composition are cyflumetofen and bifenazate, wherein the weight ratio of the cyflumetofen to the bifenazate is 50:1-1:50, and the two active compositions are prepared into various forms including missible oil, microemulsions, EW (emulsions in water), suspending agents, wettable powder, water dispersible granules, microcapsule suspending agents, suspoemulsions, and oil miscible flowable. The composition is used for preventing and controlling pest mites of crops, and especially can be used for preventing and controlling panonychus citri mcgregor and tetranychus urticae koch; and the composition has a synergistic effect, is quick-acting and long-acting, and therefore pesticide consumption is reduced and labor is saved.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition containing cyflumetate and bifenazate, which is used for preventing and controlling harmful mites in agriculture. Background technique [0002] At present, in the control of agricultural pest mites, due to the many generations of pest mites, rapid reproduction, and easy resistance, some acaricide varieties with good control effects, such as abamectin and pyridaben, have been used for many years. , the acaricide effect is significantly reduced or the effective control time of one application is very short, even for newly developed acaricides, if resistance prevention measures are not taken, resistance will usually develop quickly. By continuously increasing the frequency of use of pesticides and increasing the concentration of pesticides used, the ideal control effect cannot be achieved, and the poisonous pollution to people and the environment has also increased....
