Effecf of nitrogen and phosphorus application on the incidence of fruit borer in hybrid brinjal COBH 1

The effect of nitrogen and phosphorus on the Incidence of the fruit borer Leucinodes orbonalis was studied in brinjal hybrid COBH 1 during kharif and rabi seasons of 2000–01. The fruit damage caused by L. orbonalis weight basis ranged from 11.01–31.00 per cent. Both the seasons the fruit damage had a positive response with the level of increase in nitrogen. At the same time high levels of phosphorus promoted the early maturity and hardening of plant tissues which enabled the plants to escape the injuries of the borer.
