PRODUCT INFORMATION
Prefar 4-E is a selective preemergent herbicide that controls weeds by interfering with their normal germination and seedling development. Tests deemed reliable demonstrate that when Prefar is applied to labeled crops according to label directions under normal growing conditions, it is safe to the crop. Normal crop conditions include soil with good water drainage, acceptable soil fertility, and soil temperatures conducive to timely seed germination and plant emergence. Any deviation from normal growing conditions resulting from adverse environmental conditions or changes in production practices may alter a crop’s response to Prefar. The user should strictly comply with the soil preparation and application instructions on this label. Questions concerning the use of the productshould be directed to Gowan Company or local extension agents or university specialists.SOIL PREPARATION: Prepare the soil according to good agricultural practice. Prefar 4-E does not control emerged weeds. All weed growth and crop stubble must be thoroughly worked into the soil prior to application.

APPLICATION INSTRUCTIONS: Spray equipment should be carefully calibrated before use and checked frequently during application to be sure nozzles are free from clogging and are delivering a uniform spray pattern. Apply uniformly the directed rate of Prefar 4-E in 10 to 50gallons of water per acre. See comments for specific crop use directions.

PREPLANT INCORPORATION: Apply to well-worked soil that is dry enough to permit thorough incorporation. Incorporate to a depth of 1-2 inches before planting. One-inch incorporation is optimum, while incorporating deeper than 2 inches will result in reduced weed control or crop injury.

PREEMERGENCE APPLICATION: Apply Prefar 4-E preemergence only on crops where the application is followed by immediate irrigation.
Delaying irrigation more than 36 hours may result in poor weed control. For sprinkler irrigation wet the soil at least 2 to 4 inches deep. For furrow irrigation thoroughly wet the entire bed top (completely black out bed top).

ROTATIONAL CROP INSTRUCTIONS: Carrots and other crops on this label (or crops from labeled crop groupings) may be replanted
following applications of Prefar 4-E without restriction. All other crops should not be planted for 120 days and the soil must be tilled to a minimum depth of 4 inches prior to replanting. Prefar 4-E may be used on labeled crops grown through or under plastic.
