The mechanism of action is the same as that of fenvalerate and cyfluthrin. The difference is that it has a good inhibitory effect on mites. It can be used in the early stage of mites occurrence to inhibit the increase in the number of mites. When a large number of mites have occurred, the number cannot be controlled, so it can only be used for both insects and mites. , Can not be used for special acaricides.
Usage
High-efficiency, broad-spectrum, quick-acting pyrethroid insecticides and acaricides, mainly contact and stomach toxicity, no systemic effect. It has a good effect on Lepidoptera, Coleoptera, Hemiptera and other pests and other pests, as well as spider mites, rust mites, gall mites, tarsal mites, etc. It can treat both insects and mites concurrently, and can prevent cotton red Bollworms and cotton bollworms, cabbage caterpillars, pipe aphid, tea looper, tea caterpillars, tea orange gall mites, leaf gall mites, citrus leaf moths, orange aphid and citrus spider mites, rust mites, peach heartworm and pear heartworm, etc., It can also be used to control a variety of surface and public health pests. For example, to control the red bollworm and cotton bollworm, in the second and third generation of eggs, spray with 2.5% emulsifiable concentrate at 1000-2000 times to cure spider mites, bridge worms, and cotton bugs; control Pieris rapae and vegetable aphids respectively Spray with a concentration of 6-10mg/L and 6.25-12.5mg/L; control citrus leaf miner spray with a concentration of 4.2-6.2mg/L.
Control object
Used in wheat, corn, fruit trees, cotton, cruciferous vegetables, etc. to control malt, midge, armyworm, corn borer, beet armyworm, heartworm, leaf roller, leafworm, swallowtail butterfly, fruit sucker, cotton bollworm, red Instar insects, Pieris rapae, etc., used in grassland, grassland, dry field crops to control grass borers, etc.
Instructions
