Main dosage form 20% suspension
Mechanism of action Butyl fluoromosteryl ester belongs to the acylacetonitrile class of non-systemic acaricides, mainly through contact killing and gastric toxicity to prevent and control eggs, mites and mites, its mechanism of action is to inhibit mitochondrial protein complex, hinder electron (hydrogen) transmission, destroy phosphorylation reactions, which have a good prevention effect on pest mites at different stages of development.
Features of action Butfluoromosteryl ester is a new type of benzoylacetonitrile acaricide, with high selectivity, is a haptical acaricide, has a high activity against red spiders at all growth stages, especially for newly hatched young mites more active. Long duration of effectiveness, recommended for use at doses, duration of up to 40 days.
Suitable for crop control of pest mites of fruit trees, vegetables, tea, ornamental plants and flowers.
Red spider juvenile mites
Control objects are mainly used to control citrus red spiders, cotton red spiders and red spiders with tumor skin, and can also control red leaf mites and full-clawed leaf mites. It also has a certain control effect on pests such as cabbage moth, twill moth, dimorph borer, rice planthopper, peach aphid and other pests, as well as rice blast, powdery mildew, downy mildew and other diseases.
Use technology
To control citrus red spiders, in the early stage of red spiders, 20% butyromoldate suspension can be used 1500 times liquid to spray evenly. The prevention and control effects were 98.62% respectively. The effect of prevention and treatment in 40 days after the drug is 100%.
Prevention and control of apple two-point leaf mites, full claw mites, in the 1-2 age stage of young mites, with 20% butyromolate suspension 1500 times liquid, the anti-effect effect is outstanding.
