The label will list any crop rotation restrictions that might affect your replanting options. That's especially true if you'll be planting grain sorghum after failed cotton. You'll also want to keep the herbicide-treated soil away from new plants while cultivating the new crop, for a while at least. If you applied Dual herbicide, you can plant safened grain sorghum seed and have little risk of plant injury. Late-planted grain sorghum is more susceptible to insect damage, so it may require insecticide applications, the agronomist added.
Sunflowers are another option.
Oilseed sunflower contracts, including the newer mid-oleic oilseeds which offer a small price premium, are readily available to South Plains farmers, he added. Oilseed sunflowers are cheaper to produce than confectionary sunflowers, and a later planting date can reduce the need to treat for head moths. Black-eyed peas are another option if producers can overcome low market prices, and limited seed and contract availability, said South Plains Extension horticulturist Roland Roberts. Peas are a good soil-builder if properly inoculated, and they are compatible with cotton herbicides such as Treflan.
