NEXGROW 6441HVXR alfalfa has improved disease resistance, cold tolerance, persistence and HarvXtra forage quality. Offers excellent harvest flexibility for optimal balance of quality and yield. Features industry leading UltraCut™ alfalfa disease package.
HarvXtra® are genetically modified alfalfa products with the Roundup Ready® trait for improved forage quality, production and weed control. The technology maximizes forage quality by reducing the amount of lignin in the plant and enables growers to optimize their cutting schedules and maintain field cleanliness and productivity.
Roundup Ready® offers a significant establishment advantage for both yield potential and quality, as a result of improved weed control and crop safety. These varieties offer high levels of pure alfalfa and haylage through low acid detergent fiber (ADF), low natural detergent fiber (NDF) and high relative feed value (RFV).
The UltraCut alfalfa disease package helps you grow a healthy alfalfa crop even in field conditions susceptible to Anthracnose and Aphanomyces disease strains.
