Application:

It has the characteristics of strong striking force and fastkilling speed.It is stable to light and slow to develop pest resistance underthe same use conditions, and it is highly effective to lepidoptera larvae.Canbe used for the prevention and control of cotton crops such as vegetables, tea,fruit trees, caterpillar, aphid, cotton bollworm, moths, cotton aphid, greenblind bugs, yellow jump a small budworm, peach, orange, twenty eight star ladybeetles, tea leaf moth inchworm, tea caterpillar, tea fine moth and otherpests, for mosquitoes, flies, fleas, cockroaches, lice and other health pestsalso has a good effect.For example, cotton bollworm and red bollworm should beprevented and controlled by spraying with 10% emulsion 1000 ~ 1250 timessolution at the peak of egg hatching.When the adult and nymph were in fullbloom, cotton aphid and bollworm were prevented by 10% emulsion spray of 2000 ~3000 times.To prevent and control fruit pests, 3.75ml /100m2 10% emulsion wasused to spray 5.52kg of water.To prevent and control sanitary pests, use 10%emulsion 800 ~ 1000 times liquid spray.10% emulsion spray with 1000 ~ 2000times solution was used to control cabbage insect, peach aphid, diamondbackmoth and night moth.
