Acaricidal composition containing fluazinam and pirimicarb

Abstract

The invention relates to acaricidal composition containing fluazinam and pirimicarb and an application of the acaricidal composition, in particular to the acaricidal composition taking fluazinam and pirimicarb as main active components and the application of the acaricidal composition. The acaricidal composition comprises two effective components including fluazinam and pirimicarb as well as aidsand an excipient, and the weight percentage ratio of fluazinam to pirimicarb is (1:100)-(100:1). The acaricidal composition can have a higher synergistic effect, overcomes and delays production of drug resistance of pests, enlarges the control spectrum and has high acaricidal speed and long lasting period, the use cost is reduced, and the toxicity is relieved. The acaricidal composition can control various pests such as mites and aphids on crops, particularly has outstanding effects on harmful mites such as panonychus citri, tetranychus urticae and tetranychus cinnabrinus and has the effects remarkably superior to single agents.

Description

technical field

[0001] The invention belongs to the field of pesticides, and in particular relates to an acaricidal composition containing fluazinam and pirimicarb, a preparation method and application thereof. Background technique

[0002] Due to the unscientific and unreasonable single use and application of pesticides, the resistance of pests to the currently used pesticides is rapidly aggravated, and the service life of some new pesticide ingredients that have been invested in the research and development of high cost and long time is shortened, and the number of times of use is high at the same time. Also increased the weight of environmental pollution and increased drug cost. The annual generation number of orange red spider is mainly affected by the temperature. Usually, when the annual average temperature is around 15-17°C, 12-15 generations will occur in one year; when the annual average temperature is around 18°C, 16-17 generations will occur in one year. When the...
