  • If pest is severe, repeat the above drenching after a month.

  • If infestation is low, drench with Azadirachtin (0.15%) 3ml/litre around main trunk 2-3 litres of mixture/tree with either of the above fungicides.

  •  Avoid water logging and keep soil raked and aerated.

  • Infested trees should be uprooted and burnt, especially the root zone.

  • Pits of uprooted trees should be treated with chlorpyrifos 2.5 ml/litre, by thoroughly drenching.

  • Drench soil with chlorpyriphos 2.5ml/litre around all un-infested tress prophylactically once in six months, followed by a spray on trees with Quinalphos 2.5ml/litre, followed by Azadirachtin 1500 ppm 3 ml/litre. Avoid leaving infested trees in field after uprooting.

  In case of nematode occurrence, need based application of either phorate 25g/ plant or carbofuran 40g/plant to the basins have to be supplemented to bring down nematode population.
