Fortress® 2.5G - Granular Insecticide for Corn

Will secondary pests and corn rootworm threaten the Midwest's corn crop this spring? There's simply no way to tell. . . until it's too late. Any pest can reduce stand populations, weaken plants, slash yields and make harvest a challenge. Successful growers turn to the same proven technology they have come to rely on for corn rootworm control --Fortress 2.5G Granular Insecticde from AMVAC.

Fortress 2.5G is a granular soil insecticide for use on corn (field, sweet, popcorn, and seed) for the control of northern, western, and southern corn rootworms, wireworms, cutworms, seedcorn maggots, white grubs, and symphylans. It can be applied to conventional, conservation, and no-till corn.

Fortress 2.5G is applied at planting in a T-Band with incorporation in the top one-inch of soil or In-Furrow. It is not designed for use as a surface band behind the press wheel. The amount applied per acre varies from 4.9 lbs. for 40-inch row spacing and 9.8 lbs. for 30-inch row spacing. This is a use rate of 6.0 to 9.0 oz. per 1,000 feet for any row spacing.

Fortress 2.5G rapidly binds to the soil and has very low water solubility, resulting in low soil mobility, which minimizes leaching and runoff potential. It performs well under low soil moisture conditions due to its vapor activity.

Corn can be rotated anytime, but all other crops may be planted 30 days after the application of Fortress 2.5G. Fortress 2.5G is not systemic and will not interact with corn herbicides. Fortress 2.5G is non-corrosive to equipment and is nonflammable.

Fortress® 2.5G Management:

Fortress 2.5G should be applied as a T-Band over the row or applied In-Furrow at planting with a granular pesticide applicator properly calibrated to assure accurate placement and proper application rate. DO NOT apply as a surface band behind the press wheel.

Granules exposed on the soil surface in the turn areas at the row ends and in loading areas must be incorporated into the top one-inch of soil immediately after treating fields by discing, harrowing, or other suitable means.

Under windy conditions the use of wind shields is recommended to ensure proper placement of granules.

All registered corn herbicides may be applied to Fortress 2.5G treated corn.

T-Band Application at Planting

Fortress 2.5G can be applied in conventional, conservation, or no-till corn as a T-Band treatment. Place the granules in a band over the row behind the planter shoe and in front of the press wheel. Granules must be incorporated into the top one-inch of soil using tines, chains, or other suitable equipment.

Heavy infestations of cutworm may result in sufficient numbers of larvae surviving the treatment and damaging the corn. If this occurs, apply a rescue treatment with another insecticide registered for this use.

In-Furrow Application at Planting

Fortress 2.5G can be applied in conventional, conservation, or no-till corn as an In-Furrow treatment. Place the applicator tube either directly into or behind the planter shoe, so the granules drop into the seed furrow.

The In-Furrow application method provides optimal control of seedcorn maggots, wireworms, and white grubs.

Always read and follow label recommendations prior to use.
