Environmental & other issues

Preplant herbicide injury can cause emergence problems in certain cases. Some herbicides, such as Treflan and Fargo, cause these problems if used improperly and when cold, wet conditions follow planting. Treflan can cause short, thickened coleoptile and stunted roots when wheat is planted directly into herbicide-treated soil. It should be surface-applied or shallowly incorporated and the wheat planted below the incorporation zone.
