Henbit control was average. With Harmony GT we can expect the same thing. These two products can provide some corn stunting under cool, wet conditions, especially on light, sandy soils. It's labeled from seedling emergence until the corn reaches 12 inches in height. Suggested use rate is 1.5 to 2.0 quarts per acre.
Pinnacle can provide excellent control of pigweed and lambsquarters under good growing conditions.
If you are in a sensitive area where the Banvel type products cannot be used, Pinnacle could be an alternative. We'll probably see a few new products in 2001. It replaces Turbo which was a blend of Dual II plus metribuzin. It will be either a co-pack or a blend of Command plus Authority. As mentioned in the small grain section, Harmony GT is really Pinnacle.
