Integrated control of Meloidogyne incognita on brinjal Kuriyan K. John, Sheela M.S. College of Agriculture, Vellayani. Presented at Nematology Symposium held at Coimbatore, India in February, 1981 Abstract The effect of cultural operations and nematicides as nursery treatment and as spot application in the control of root-knot nematodes, M. incognita on brinjal was studied in a field trial. Normal digging (10 cm), deep digging (20 cm), nursery treatment of metham sodium @ 25 ml/sq.m. and spot application of aldicarb @ 1 kg a.i./ha at the time of transplanting were tried in different combinations. The growth parameters like number of leaves, height of plants, shoot weight arid root weight showed no significant difference in the main field. However, at final harvest of the plants normal digging plus nursery treated seedlings plus aldicarb, applied plants gave a significantly higher number of leaves. Also, deep digging plus nursery treated seedlings plus aldicarb applied plants gave the highest shoot and root weight of 136.5 g and 16.68 g, respectively. The yield did not vary significantly between treatments, but normal digging plus nursery treated seedlings plus, aldicarb applied plants gave the highest yield of 13.63 kg from 25 plants, closely followed by deep digging plus nursery treated seedling, plus no aldicarb application, with 13.3 kg from 25 plants. Though the soil nematode population was not significantly different between treatments, deep digging plus. nursery treated seedlings plus aldicarb applied plants had the minimum number of root-knots and minimum number of root population between treatments. This indicates that deep digging decreases the nematcde population prior to transplanting and when the seedlings raised from nematicide treated nursery, are transplanted, there is less chance of increase of nematodes.
