Conference Object The Effect of Sodium Bicarbonate on Powdery Mildew in Tomato(International Society for Horticultural Science, 1999) Demir, S.; Gui, A.; Onogur, E.In this study on the integrated control of diseases and pests of cucumber and tomatoes in greenhouses, the effectiveness of sodium bicarbonate (NaHCOs) against powdery mildew on tomatoes was tested. Three chemical treatments; namely, wettable powder (WP) sulphur, a fungicide with the active ingredient triforine which is not harmful to natural enemies of pests and NaHCC<3 were used. These treatments were applied to three tomato varieties in the greenhouse at the first appearance of powdery mildew symptoms. Treatment with WP sulphur completely prevented powdery mildew disease after two applications, whereas five triforine and NaHCC<3 were required.In addition,no statistically significant differences were determined between the treatments in each of the tomato varieties in terms of yield.
