Management of Root-Knot Disease in Phaseolus vulgaris Using Potassium Fertilizer and Biocontrol Agents

Rushda Sharf, Hisamuddin, Abbasi and Ambreen Akhtar

The experiment was conducted to determine the effect of different doses of potassium fertilizer (K2O) along with the biofertilizers, Trichoderma harzianum, and Pochonia chlamydosporia, in the management of the root-knot disease caused by the root-knot nematode (Meloidogyne incognita) and on the growth and physiological parameters of Phaseolus vulgaris. From the result it was observed that the application of potassium along with biofertilizers in the treatment T-7 in which plants were treated with double dose of potassium along with both fungal biocontrol agents and root-knot nematode, improved all the growth as well as biochemical parameters viz, chlorophyll, protein, nitrate reductase, nitrogen and phosphorus contents and reduced the number of galls per root system in comparison to the control and other treatments.
