After receiving registration approval from the U.S. Environmental Protection Agency (EPA), DuPont Crop Protection has introduced DuPont Afforia herbicide, a preplant herbicide for soybeans and other field crops that provides excellent burndown and residual control of many of the most challenging weeds.
The lack of reliable traits to distinguish Palmer amaranth and waterhemp during vegetative stages complicates efforts at stopping the spread of Palmer amaranth across Iowa.
Although unpredictable weather may delay application timing of spring herbicides, more growers are adding a burndown application in the fall to their weed management program.

Old and new crop soy futures continue diverging. Prospects for a massive autumn harvest keep weighing upon new crop soy prices, especially in the wake of Tuesday’s crop tour results. However, persistent spot market strength and talk of vigorous demand are strongly supporting the nearby bean and meal contracts. Fresh five-year lows in palm oil prices are undercutting soyoil quotes. September soybean futures climbed 7.25 cents to $11.275/bushel early Wednesday morning, while November futures dropped 2.5 cents to $10.5025. September soyoil dipped 0.20 cents to 32.46 cents/pound, but September soymeal surged $6.7 to $406.5/ton.
