To preserve the benefits and insect protection of the YieldGard® Family of corn technologies, an Insect Resistance Management (IRM) plan must be part of every grower’s short-term and long-term production strategies. IRM plans are mandated by the U.S. Environmental Protection Agency (EPA), and Insect Resistance Management is a requirement for purchasing YieldGard Corn Borer, YieldGard Rootworm, YieldGard Plus, YieldGard VT Rootworm/RR2® and YieldGard VT Triple® corn. Continued use of the YieldGard products listed below depends on compliance with EPA registration conditions: YieldGard Corn Borer insect-protected corn provides while-season, in-plant protection against European corn borer, southwestern corn borer, sugarcane borer, and southern corn stalk borer. YieldGard Corn Borer also suppresses corn earworm, fall armyworm, and stalk borer. YieldGard Rootworm insect-protected corn provides effective and consistent, in-plant control of western corn rootworm, northern corn rootworm, and Mexican corn rootworm throughout the larval feeding period. YieldGard Plus insect-protected corn combines the insect protection spectrum of YieldGard Corn Borer and YieldGard Rootworm technologies and provides effective and consistent control of born borer and rootworm throughout the larval feeding periods. NEW - YieldGard VT Rootworm/RR2 insect-protected corn provides improved consistency and better control, compared to current rootworm-protected products of western corn rootworm, northern corn rootworm, and Mexican corn rootworm throughout the larval feeding period. NEW - YieldGard VT Triple insect-protected corn combines the insect protection spectrum of YieldGard VT Rootworm/RR2 and YieldGard Corn Borer technologies and provides affective and consistent control of corn borer and rootworm throughout the larval feeding period. Combat Resistance with a Refuge Resistance has developed in nature to some pest control tactics. The risk of insect resistance is real, but may be minimized with proper planning. The best way to preserve the benefits and insect protection of YieldGard corn products is to develop and implement an IRM plan. The key component of any YieldGard IRM plan is a con refuge. A refuge is simply a block or strip of corn that does not contain a Bacillus thuringiensis or B.t. technology for controlling targeted corn insect pests. The primary purpose of a refuge is to maintain a population of corn insect pests that are not exposed to the B.t. proteins found in YieldGard technologies. The lack of exposure to B.t. proteins allows susceptible insects nearby to mate with any rare resistant insects that may emerge from B.t. corn. Susceptibility to B.t. technology would then be passed on to their offspring, helping to preserve the long-term effectiveness of YieldGard technologies. The refuge should be planted with a similar hybrid, as close as possible to, and at the same time as, the YieldGard corn technologies to help reduce the risk of corn borer and/or corn rootworm developing resistance. With an effective IRM plan in place, growers will continue to benefit from the effective and consistent corn borer and rootworm protection and top yield potential found in YieldGard corn. As a condition of registration of YieldGard products by the EPA, seed companies are required to conduct IRM compliance assessments during the growing season to ensure grower compliance. Failure to follow IRM guidelines and properly plant a refuge may result in the loss of access to YieldGard technologies. Please do your part to ensure these technologies are preserved by fully cooperating in refuge management. |
