Weed patches seem to dot the harvested landscape this winter. Delayed harvest and wet conditions coupled with high fuel prices meant less fall tillage to get them under control.
There's new relief. Autumn herbicide from Bayer CropScience can be used as a burndown treatment after harvest, as long as it is applied prior to ground freeze. Next spring, it can be used up to 30 days before planting corn or 90 days prior to planting soybeans, sweet corn, seed corn and popcorn.
Along with dandelion and marestail, the herbicide tackles common winter annuals and perennials, including chickweed, hemp nettle, henbit, horsenettle and purple deadnettle.
Weeds like chickweed and purple deadnettle are easier to control before they bloom and flower in the spring. There's also evidence these weeds help harbor soybean cyst nematode.
