Agrisure GT provides exceptional tolerance to in-crop applications of glyphosate-based herbicides. Corn hybrids with Agrisure GT are carefully selected to provide not only outstanding glyphosate tolerance via the trait, but also to preserve the genetic potential of the hybrid via the proven inbred line conversion process.

Agrisure CB/LL allows hybrids to reach their maximum yield by providing excellent control of European corn borer (ECB) plus other damaging insects. Agrisure CB/LL features the Bt11 event, which has been protecting cornfields since it was introduced in 1997. In addition, all hybrids with Agrisure CB/LL are tolerant to LIBERTY® herbicide, providing growers with another option for weed control.

Agrisure RW offers excellent built-in control of Northern, Western and Mexican corn rootworms in leading hybrids, offering outstanding yield results. Agrisure RW has been placed in leading Syngenta genetics utilizing an industry-leading trait conversion process that ensures hybrids will reach their full yield potential. Innovative stacked combinations are available including Agrisure GT/RW, Agrisure GT/CB/LL, Agrisure CB/LL/RW, and Agrisure GT/CB/LL/RW.

Common Refuge Planting Requirements

A common refuge is a field or area of corn that does not contain Agrisure CB/LL/RW or other trait products for controlling corn borers and/or corn rootworms. Each grower planting corn hybrids with Agrisure CB/LL/RW must plant his own refuge. The refuge may be planted in a variety of configurations as illustrated in this stewardship guide. Specific requirements for the common refuge are as follows:

1. A minimum of 20 percent of field corn acres must be planted to corn hybrids that do not control corn borer and/or corn rootworm. If you plant corn hybrids with Agrisure CB/LL/RW in cotton-growing regions, you must plant a minimum of 50 percent refuge.
2. Common Refuge planting options include blocks adjacent to AGrisure CB/LL/RW corn fields, perimeter strips or in-field strips.
   1. The common refuge must be planted within or immediately adjacent (e.g., across the road) to Agrisure CB/LL/RW corn fields.
   2. Common refuge planted as in-field or perimeter strips must be at least 4 consecutive rows wide, but the preference is for 6 rows.
3. A neighbor's field does not meet the refuge requirement.
4. Common Refuge Insecticide Treatment requirements:
   1. Insecticide treatment for controlling European Corn Borer (ECB), corn earworm and/or Southwestern Corn Borer (SWCB) may be applied to the refuge if economic thresholds are reached for one or more of these target pests. Contact local or regional professionals, such as your county extension agent, if you have questions regarding the economic threshold of target pests.
   2. Bt-based microbial insecticides may not be applied to the corn refuges.
   3. The common refuge corn acres can be treated for corn rootworm larvae and other soil pests with a soil-applied or seed-applied insecticide.
   4. Insecticides labeled for control of corn rootworm adults can be applied to the common refuge provided the field with Agrisure CB/LL/RW hybrids is treated in a similar manner.
5. The common refuge should be planted with a hybrid that is agronomically similar to and managed similarly to your corn with Agrisure CB/LL/RW.
6. The common refuge should be planted in fields with a similar history as the Agrisure CB/LL/RW.
   1. If the common refuge is planted in a field that is in a crop rotation system, the corn hybrids with Agrisure CB/LL/RW must also be planted in a field that is in a crop rotation system.
   2. If the common refuge is planted on continuous corn, the corn hybrids with Agrisure CB/LL/RW may be planted on either continuous or in a crop rotation system.
