JEMSTAR is a broad-spectrum insecticide used to control a wide range of lepidopteran pests in various crops, including cotton, vegetables, fruits, and ornamentals. It is an avermectin insecticide that works by disrupting nerve function in insects. Emamectin benzoate is a highly effective insecticide that provides residual control of lepidopteran pests.

Active Ingredient

The active ingredient in JEMSTAR is emamectin benzoate, an avermectin insecticide with the molecular formula C51H77NO13. It is a white, odorless, and crystalline solid.

Mode of Action

JEMSTAR works by disrupting nerve function in insects. Emamectin benzoate binds to glutamate-gated chloride channels (GluCls) in insect nerve cells, preventing the flow of chloride ions. This disruption of nerve function leads to paralysis and death of the insect.

Application Methods

JEMSTAR can be applied as a foliar spray or a soil drench. Foliar spray is the most common application method. It involves spraying the insecticide onto the foliage of the plants using a backpack sprayer or a boom sprayer. Soil drench involves applying the insecticide to the soil around the base of the plants.

Restrictions

JEMSTAR should not be applied to crops that are under stress from drought, flooding, or other environmental factors. It should also not be applied to crops that are grown on sandy or gravelly soils.

Precautions

JEMSTAR is a moderately toxic insecticide, so it is important to wear protective clothing, such as gloves, goggles, and a respirator, when handling and applying the insecticide. JEMSTAR is moderately toxic to fish and other aquatic organisms, so it should not be applied near water sources.

Storage and Disposal

JEMSTAR should be stored in a cool, dry place out of reach of children and pets. The insecticide should not be stored for more than one year. Empty containers should be rinsed three times with water and disposed of according to local regulations.

Additional Notes

Emamectin benzoate is a highly persistent insecticide that can remain in the soil for several months. It is important to follow the recommended application rates and application methods to minimize the risk of environmental contamination. Emamectin benzoate is also a potential groundwater contaminant, so it should not be applied in areas where groundwater is used for drinking water.
