Similar to the naturally occurring signal-transmitting acetylcholine, imidacloprid can excite certain nerve cells by acting on a receptor protein.It has special efficacy against pests with piercing-sucking mouth such as aphids, rice planthopprs, whiteflies, leafhoppers and thrips. In addition, this product can efficaciously prevent and kill coleopterous, dipterous and lepidopterous pests such as rice borers, rice leaf bettles, rice weevils, citrus leaf miners and potato bettles etc.Because of the excellent systemic activity and the relatively low rate of application of this new insecticide, the active ingredient can be used as seed dressing as well as for foliar and soil treatment.Feature:high efficacy and persistencetoxicity and safetybroad spectrum, excellent systemic activityno cross-resistanceStorage:Sealed tightly and stored away from light in a cool and dry place Shelf life: 2 years.
