Ensure good spray coverage to run-off for optimal disease control. Sprayers should be calibrated before use.

Under some conditions Karbyon can cause phytotoxic effects on plant leaves. Apply a small amount of the product to susceptible plants and observe for 48 h before spraying the rest of the crop.

Withholding period: Nil

Restraints: DO NOT spray under conditions that give slow drying i.e. high humidity, cool temperatures. DO NOT spray early morning, late evening, or during the hours of darkness. These conditions may give rise to phytotoxic damage to plant or fruit. DO NOT spray plants under stress. As Biostart is not able to test on every plant species and variety, it is recommended that growers test the product on their plants prior to treating large areas, particularly when using higher rates.
