Abstract:

An investigation was carried out for evaluating the table grape genotypes against incidence of mites in Sector No. 70, UHS, Bagalkot, Karnataka after fore pruning (October) 2016 at different phenological stages. Results revealed that among 12 grape genotypes studied, significantly lowest mites population was recorded in Red Globe (T12) (8.63 mites/sq. inch of leaf) after 115 DAP. Significantly the highest population of mites was recorded in Fantasy Seedless (T10) (14.48 mites/sq. inch of leaf) after 115 DAP. Correlation studies revealed that the incidence of mites per sq. inch of leaf was significant and high positively correlated with sugar and amino acid. The incidence of mites per sq. inch of leaf was significant and high negatively correlated with phenol and tannin.
