Before transplanting the plant, apply 90 kg Urea, 250 kg Single Super Phosphate (SSP), and 100 kg Muriate of Potash (MOP) along with FYM.
Divide 90 kg of Urea into three parts. The first part of urea is given 30-40 days after transplanting, the second part after the next 30 days, and the third installment or part in the form of top dressing at the time of flowering.

Symptoms

Phytophthora rot occurs when fruits are in contact with the soil or mycelia grows through the peduncle into the fruit.

Raised beds are necessary to avoid the problem of waterlogging in heavy soils.
In sandy soils, however, sowing can be taken up in flatbeds.
Raised beds of size 3 x 1 m and 10-15 cm in height are prepared.
About 70 cm distance is kept between two beds to carry out operations of watering, weeding, etc.
The surface of the beds should be smooth and well leveled. Well-decomposed FYM or leaf mold may be mixed with the soil at the time of bed preparation.
To avoid mortality of seedlings due to damping off, the drenching of the beds with Mancozeb 75% WP @400-600 gm/acre, is effective.

The damage to the fruits starts soon after transplanting and continues till harvesting of the fruits.
It can reduce yield by as much as 70%.
Multiple overlapping generations occur in warm climates.
The short pinkish larva of the pest initially bore into the terminal shoots resulting in withering and drying of the shoot.
In the later stage, it bores into the young fruits by making holes and feeds inside and lose their market value fruits plugged with excreta.

Management:

Install pheromone trap @ 5 /acre .
Continuous cropping of brinjal on the same piece of land should be avoided.
Fruits showing boring should be picked and destroyed.
Spray the crop with Cypermethrin 10% EC @ 300ml/acre or Lambda Cyhalothrin 5% EC @ 200-250 ml/acre at fortnight intervals starting from 35 days after transplanting to control the pest.
Best results are obtained when all the affected fruits are removed before spraying.
