Problems Attack Weed

Growing cotton in a conservation tillage system requires a good burndown treatment for weeds and cover before planting. This is becoming more complicated because of glyphosate-resistant horseweed in many areas.

Some areas are finding this resistant horseweed continuing to emerge after the cotton has been planted. This is causing many farmers to consider residual herbicides in their burndown.

Another weed that emerged suddenly in northern Alabama last year is common groundsel. This weed was difficult to control and served as a host for false chinchbugs. The chinchbugs moved to cotton and killed cotton plants in several fields last season. Determining what weeds are present in the fields before burndown will be critical in determining herbicide combinations to use.
