The effect of 3 chemical fungicides, Wettable sulphur, Karahtane and Nimrod separate or in combinations with either copper exychloride or diathane was studied on Thompson seedless grapevines growth and mineral leaf composition along with berry moisture and dry matter. All treatments, generally, stimulated internode length and thickness. The weight of pruning also was significantly affected by such treatments. Morever, results obtained revealed that the highest leaf nitrogen content was by using Nimrod alone-Karathane alone increased leaf phosphorus content leaf potassium content was negatively effected by using the afore mentioned fungicides. The effects of these treatments on berry moisture and dry matter was instable in both season of study.
