Grandex is a post-emergent, granular insecticide used to control a wide range of insects on turfgrass, ornamentals, and agricultural crops. It is a contact insecticide, meaning it must come into direct contact with the insects in order to be effective.

Mode of Action

Grandex works by disrupting the insect's nervous system, leading to paralysis and death. It specifically targets the nicotinic acetylcholine receptor (nAChR), which is a neurotransmitter receptor that is critical for the transmission of nerve impulses. When Grandex binds to the nAChR, it prevents the normal transmission of nerve impulses, leading to paralysis and death of the insect.

Benefits of Grandex

• Wide-spectrum activity against a wide range of insects
• Contact activity for protection on both above- and below-ground insects
• Rapid and long-lasting control
• Effective against a variety of insects, including beetles, caterpillars, grubs, and ants
• Safe for most crops and the environment
• Easy to use as a granular application

Application Rates and Methods

The recommended application rate of Grandex varies depending on the crop, the insect being controlled, and environmental conditions. For granular applications, it is typically applied at 40 to 100 pounds per acre.

Safety Precautions

Grandex is relatively safe to use when handled properly. However, it is a good idea to wear gloves, long sleeves, and pants when applying the product to avoid skin contact. Wash thoroughly with soap and water after handling the product.
