A drift influencing composition for use with agricultural chemicals for aerial distribution to farm crops or the like comprising a quantity of water soluble friction reducing resin, high molecular weight (300,000 to 4,000,000) polyethylene oxide in solution with water in the concentration range of 70 parts per million by weight to 200 parts per million by weight to retard the drift of aerial sprayed agricultural chemicals, and in the concentration range of one-half parts per million by weight to 70 parts per million by weight to enhance the drift of aerial sprayed agricultural chemicals, which functions to reduce surface tension of the solution and enhance efficient aerial spraying and providing sufficient coagulation to minimize wind induced drift.
