Damage of Brinjal Plants

[victorka]

Hello,


I have planted brinjal plants around half acre area 2 months before.
Now I find some of the plants are dried and damaged.
Before a month I found some of of the insect damage the stem and the stem got damped. I have applied monochlorovous and then Bhrahmastra. But nothing happened. The insects are still present. Please view the attached photo.

I will be grateful if someone can give me concrete solution, so that I can save my plants.

Regards,
Siddhartha.

Hello sir,
Shoot and fruit borer, is the most destructive pest of brinjal.

The larva of brinjal shoot and fruit borer burrows into the petioles and tender shoots. It results in drooping of leaves and shedding of flower buds.

Severe damage is mainly caused to the developing fruits by the caterpillars as they tunnel inside the fruits.
management
Continuous cropping or ratooning may be avoided. Adjust the time of planting by transplanting up to 4th week of June. Dip the roots of the seedlings for 3 hours in imidacloprid solution prepared at 1ml/lit before transplanting.

Carry out shoot clipping operation at weekly interval. Collect and destroy affected shoots and fruits.

Apply neem cake at 250kg/ha at 30 days after transplanting. Keep pheromone traps at 12 nos./ha

Spray azadirachtin 0.03 per cent profenophos 0.05 per cent or carbaryl 50WP at 2g/lit starting from one month after transplanting at 15 days interval.

Soil application of carbofuran 3G at 30kg/ha 10 days after transplanting is also very effective. Cultivation of brinjal under protected cultivation (net house condition) is found to reduce the incidence of shoot and fruit borer.

A single caterpillar may destroy as many as 4-6 fruits. Damaged fruits show circular exit holes.

The entry holes on the brinjal fruit can also be seen plugged with excreta thus making the fruits unfit for consumption and marketing.
