Management of Meloidogyne incognita by using potassium humate in Brinjal (Solanum melongena L.)

Experiments were conducted under green house and field conditions to test the efficacy of potassium humate for the management of root knot nematodes in brinjal. Two g of potassium humate/kg soil was found to be effective in reducing the gall index and nematode population. The reduction in the reproduction factor (1.3) of the nematode may be responsible for the decrease in root knot indices. All the dosage of potassium humate had a significant effect in terms of nematode reduction and yield increase (58.1%) under field conditions. Management practices for nematodes are changing due to increased costs, non-availability of chemical nematicides when needed, hazardous nature and restrictions on nematicide use.
