Problems solved by technology

[0003] Fenoxycarb belongs to non-terpene carbamate, has stomach poisoning and contact killing effects, and insect growth regulating effects. Strong juvenile hormone activity, can lead to ovicide, inhibit metamorphosis in adult stage and molting in larval stage, cause death in late larvae or pupal stage, especially effective for mites, long-lasting, harmless to beneficial organisms
[0004] In practical applications, the application of chemical agents is the most effective means of preventing and controlling plant diseases and insect pests. However, the continuous application of a single chemical acaricide in high doses for a long time may easily cause a series of problems such as drug residues and environmental pollution. However, reasonable chemical acaricides One of the most effective ways to solve the above problems is to compound or mix with the ability to expand the acaricidal spectrum

Abstract

The invention provides an agricultural acaricidal composition and application thereof, and belongs to the field of acaricides. The acaricidal composition is prepared by compounding effective components: fluazinam and fenoxycarb, and has the characteristics of high acaricidal activity, long lasting time, low toxicity, environment friendliness and the like. The acaricidal composition comprises effective components: fluazinam and fenoxycarb, and the mass ratio of fluazinam to fenoxycarb is 10:1-1:10. The fluazinam and the fenoxycarb are reasonably compounded, so that the acarid control range canbe expanded; the acaricidal composition can be used as an agricultural acaricide, can be used for controlling acarid of crops, especially has an obvious effect on panonychus citri, tetranychus urticae, citrus red mites and the like, and has good popularization and use prospects.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to the field of agricultural acaricides, in particular to an agricultural acaricide composition and its application. Background technique [0002] Fluazinam is a broad-spectrum and high-efficiency protective fungicide, which is very effective against Alternaria, Phytophthora, Plasmodium, Sclerotinia and Scabella, and is effective against benzimidazole and Botrytis cinerea, a carboximide fungicide, also has a good effect, and it also has a good effect on rice damping-off caused by Rhizopus. The prevention and control mechanism of fluazinam is to block the energy synthesis of mites, and it has good egg-killing and larval-killing effects on a variety of plant pest mites. The mite eggs change color and lose their activity after contacting the liquid medicine, and cannot hatch normally at the same time, with a long lasting effect. [0003] Fenoxycarb belongs to non-terpene carbamate, has stom...
