Product Overview

Gemini Granular Herbicide is a combination of selective pre-emergent herbicides for the control of over 120 listed grass and broadleaf weeds with low risk of phytotoxicity for up to 4 months. It contains the two actives Prodiamine, which inhibits microtubule assembly during cell division and Isoxaben, which disrupts cell wall development. It is formulated with the R-50 Optimizer, a powerful weed management tool to control more by using less. Once applied and water, the R-50 Optimizer moves more of the active off the carrier and spreads it further out to create a wider barrier of protection. This allows for more efficient and effective control with less product use and opening up more flexibility to use Gemini Granular Herbicide up to 3 times a year. Use on field ornamentals, container ornamentals, landscape ornamentals and christmas tree farms. This product comes in a 50 lb bag of granules.
