Abstract
The resistance inducers, i.e. Ammonium bicarbonate, Bion, Photophor, Oxalic acid and Salicylic acid as well as the fungicide Teldor 50% caused significant reduction in the linear growth of the fungus Botrytis cinerea on PDA medium. This reduction was increased by increasing the concentration of these chemicals. Furthermore, the fungicide Teldor 50% was the most efficient in this regard compared with the tested resistance inducers.
Application of the tested chemicals as dipping, spray and dipping + spray resulted in significant reduction in the gray fruit rot caused by B. cinerea. This reduction was, somewhat, in the same trend of the reduction in the linear growth. Also, the reduction in the infection by fruit-rot reflected on the obtained marketable fruit yield.
Application both resistance inducers and the fungicide Teldor 50% caused considerable increases to the activity of oxidation reduction enzymes, i.e. polyphenoloxidase, peroxidase and ascorbic acid.
In general, combined treatment was superior in this regard.
