Abstract
Treatments of 0, 2% and 4% Folicote in water were applied to runoff at 0, 7 and 16 days after bloom (DAB) on ‘Norgold Russet’ potatoes (Solanum tuberosum L.) grown in the greenhouse. Folicote is a wax emulsion antitranspirant (AT) containing 60% solids. Treatments at 0, 7 and 16 DAB with 2% AT reduced water uptake by >20% for 4, 8, and 14 days respectively, following application. AT treatment at 4% reduced water uptake >40% for 10-14 days. There was no significant reduction of tuber yield even at the higher concentration.Keywords
