DIRECTIONS FOR USE
Captan 50 W is a microfine wettable powder for use in water as a spray for the control of certain fungus diseases of fruit, vegetables and ornamental crops, and as a soil treatment for the control of certain seed rots and damping-off diseases. Spray injury may result if captan is used with, immediately before or closely following an oil spray. DO NOT APPLY BY AIR.

COMPATIBILITY
Captan 50 W can be used at recommended dosages in accordance with spray schedules or recommendations by Provincial or Experiment Station personnel. Do not combine with oil and strongly alkaline materials such as hydrated lime, which reduces the fungicidal activity. Do not use this product in combination with, immediately before or closely following an oil spray, or with solvent formulations of Parathion products.

MIXING
Pour recommended amount of this material on surface of water in nearly filled spray tank or pre-mix in a bucket half filled with water and pour mixture through screen into nearly filled spray tank. Add balance of water to fill tank. Keep agitator running during filling and spraying operations. Do not allow mixture to stand.

RECOMMENDATIONS
Unless otherwise specified, rates are given in terms of Captan 50 W per 1000 liters of water. If expressed in kg per hectare, sufficient water to provide thorough coverage should be used. Except as specified, begin applications before or at first sign of disease and repeat as necessary to maintain control but observe limitations. Consult authorities for specific information as the timing, number and rate of applications needed will vary with local conditions.
