Registered Uses Corn/atrazine.
Benefit Improved postemergence activity of atrazine.
Mode of Action Partially dissolves waxy cuticle of weeds allowing atrazine to penetrate more readily.
Mixing Fill spray tank with water allowing space for subsequent addition of atrazine and oil; engage agitation and pour in premixed slurry of atrazine in water; add Kornoil last. Avoid excessive agitation of the spray mix as this may cause coagulation or buttering out.
Unique Characteristics To prevent a build-up of oil in the sprayer, empty the tank as completely as possible before refilling. Some injury may occur if the crop is stressed (cold weather or hot, dry weather).
