What are the reasons for occurrence of root rot disease and suggest control measures?
In the case of shoot rearing practices, shoots are frequently pruned and lichens grow on the shoots. This will be resulting in decaying of barks and stems to cause root rot. As soon as symptoms of sudden withering of leaves and drying / death of plants take place, uproot the infected plants and burn it. Remove the soil up to one foot from the infected spot. Dust the pit with 3-4 g Dithane M-45 and new sapling be planted after treating the root system with1 % Dithane M-45 solution. Besides, a biofungicide Raksha @ 1kg for 100 plants may be applied (mix 1 kg of Raksha with 50 kg of FYM,keep under shade for one week & then apply). Each plant may be applied with 500 g of the mixture in the root zone, but for new sapling, 500 g may be put in the pit and root of sapling should be treated with1 % Dithane M-45 solution for 30 minutes. After covering the root with soil, irrigation may be given.
