dc.description.abstractThis study on the determination of residues of carbaryl and endosulfan on/in mango fruits is in partial fulfilment of the M. Sc. (Agri.) Course which VALAND VIT'l'HALBHAI MAGANBHAI has taken up under the direction of Dr. Shah A. R., Professor and Head, Department of Entomology, N. M. College of Agriculture, Navsari. Chemioal and micro bio-assay of residues of recommended insecticides, viz., carbaryl and endo.ulfan which were used at the concentration of 0.2 per cent and 0.075 per cen~respectivel~ as schedule of spraying in 1976-77 and only one spraying in 1977-78 as a part of insect pest management programme in mango crop have been carried out. In the chemical assay the residues of carbaryl on the mango fruits found immediately after the last spraying was 58.15 ppm in 1976-77, and the same after 3rd, 7th and 25th days were 37.22, 18.49 and 10.30 ppm respectively. Similarly, it was 52.56 ppm as initial deposit in 1977-78 and the same after 3rd, 7th and 19th day of one spraying were 38.00, 20.50 and 8.80 ppm respectively. 'thus the reduction percentage of carbaryl residue found were 36.00, 50.32 and 65.71 per cent in 1976-77 and 27.70, 61.00 and 83.26 per cent in the year 1977-78 on 3rd, 7th and 25th/19th day after spraying of oarbaryl respectively. The half life of carbaryl residues wes· 3.19 and 3.00 days in 1976-77 and 1977-7.8 respectivelyen_US
