Fall Seeded Crops and Herbicide Residues in the Soil
Herbicide applications made to corn, sorghum, and soybeans must be reckoned with where alfalfa or winter wheat is being considered for fall planting on drought stricken fields.
The guidelines that follow come from labels, product literature, research, and experience. They have been established to protect the user and manufacturer and contain safety factors for average growing conditions. Drier than normal June, July and August weather has undoubtedly prolonged soil longevity of some products.
We have chosen to discuss herbicides that may present a problem. Herbicides not discussed are expected to present no problem. Discussions below are for each individual herbicide. Where combinations have been used, the most phytotoxic material should be used to determine the planting decision.
