Dry conditions may change intended crop use plans. The need for forage may be critical. Several herbicides have a minimum interval between application and crop use for forage or grazing. Tolerances are based on data for intervals shown in the table below. An interval of 30 to 40 days is not likely to be a factor limiting the use of corn for silage. For most fields, a 30 to 40 day requirement will be met by late July or early August. Tolerances for forage or grazing must be established before crop use for these purposes can be recommended. Refer to product label for specific precautions regarding livestock removal prior to slaughter or moving to other grazing areas.
