physical properties, and plant safety
Physical incompatibility - (ANSWER)is the failure of the products to stay uniformly mixed in the spray
tank
may settle, layer, curdle, or gel
may be related to pH, chemical composition and temp of carrier
chemical incompatibility - (ANSWER)alter of activity of the pesticide when mixed together either
