Acaricidal composition containing chlorfenapyr and spirodiclofen

Abstract

The invention discloses an acaricidal composition containing chlorfenapyr and spirodiclofen and a preparation method and application thereof. The acaricidal composition is characterized by containing the chlorfenapyr, the spirodiclofen and other aids, wherein the weight ratio of the chlorfenapyr to the spirodiclofen is (0.1-30):(0.1-30). The acaricidal composition can be applied to the prevention and control of various harmful acarids. The composition is safe and environmentally-friendly, and has low cost and good effects. Indoor virulence tests and field tests prove that: the composition has obvious synergy. Moreover, the compounding of the chlorfenapyr and the spirodiclofen is not reported in China and foreign countries, so the acaricidal composition is provided.

Description

technical field [0001] The invention belongs to the field of agricultural chemicals, and relates to the compounding of pesticides, insecticides and acaricides, in particular to the compounding and application of the acaricides with spirodiclofen and chlorfenapyr as main active ingredients. Background technique [0002] The application of chemical agents is the most effective means of controlling plant pests and mites. However, long-term continuous high-dose application of a single chemical insecticide is likely to cause problems such as pesticide residues, environmental pollution, and the development of drug-resistant pest mites. Reasonable compounding or compounding of chemical insecticides can expand insecticidal spectrum, improve control effect, prolong application period, reduce dosage, reduce phytotoxicity, reduce residue, and delay the occurrence of drug resistance and drug resistance of pest mite With positive characteristics such as development, compounding or mixin...
