Why do the malligai leaves become yellow and how to rectify this?
It is caused by three factors viz., iron deficiency, nematode infection and root rot disease. i) Iron deficiency: Spray Ferrous sulphates 5 g/l at monthly intervals until the chlorotic symptoms disappear. ii) Nematode: Test the soil for nematode infection. Apply 10 g of Phorate granules near root zone and irrigate. iii) Root rot: Drench the soil around the plant with Copper oxychloride at 2.5 g/lit.
