Foliar Application of Nutrients and PGR on Butea monosperma and Survival of Kerria lacca (Kerr)

The field study was conducted during 2014–15 in Dungariya village, Barghat block, Seoni district, Madhya Pradesh, in RBD format, with four replications and six treatments viz., Micro-nutrients, Zinc, Boron, PGR (Chlormequat chloride 50% SL), Humicacid and Controli.e. waterspray. Meannumber of lac insect settled per 2.5 sq. cm varied from 49.95 to 51.11 at 30 day after broodlac inoculation. It was highest in Zinc (51.11) followed by PGR (51.05), Boron (50.73), Control (50.31), Micro-nutrients (49.98) and Humic acid (49.95). There was no significant difference among the treatments at 30day after BLI. The mean live lac cell count per 2.5 sq. cm at harvest was highest in PGR (30.09) followed by Zinc(28.55), Boron(27.42), Micro-nutrients(23.33), Humic acid(21.19) and Control (19.08). Therewas significant difference in all the treatments over the control. The per cent survival of insect over that at was highest in PGR (58.95) followed by Zinc (55.86), Boron (54.06), Micro-nutrients (46.68), Humic acid (42.43) and Control (37.93).
