■ Manufacturer: Bayer CropScience

Brand Name: Autumn (Label Change)
Active Ingredient: Iodosulfuron-methyl-sodium
Crop Designation: Corn; Soybeans.

University trials show a burndown application of Autumn delivers outstanding weed control on tough weeds, including: Canada thistle, common chickweed, dandelion, hemp nettle, henbit, horsenettle and marestail.

Along with the spring application option, growers can use Autumn in the fall as a burndown to eliminate winter annuals. Fall burndown applications of Autumn have the added bonus of helping to manage pest pressure from black cutworms, as they cannot survive in fields without the cover provided by winter annual weeds. In addition, a clean field reduces the support of nematodes and grubs.

Autumn provides a residual that other herbicides do not. It is also flexible and can be used with various tankmix partners for a broader spectrum of weed control.

Additionally, chemigation will mean immediate activation and incorporation of Chateau into the soil for a more streamlined treatment process and fewer trips across the fields for resource-stressed growers. In addition to its superior long-lasting control, Chateau is broad spectrum, farm-friendly (rotational flexibility) and can be used on all potato varieties. It requires minimal PPE and is clean and easy to handle and apply. Chateau contains the active ingredient flumioxazin, a PPO inhibitor that binds to the soil and has low water solubility.
