Special practices – Training
• Brinjal growing on single rows on 2m wide beds with 2 parallel shoots trained vertically, one on each side of the row, or in double rows on 3m wide beds with 3 shoots trained vertically in the plane of row. • The latter system, fruiting began earlier and the
proportion of good quality fruit and total fruit yield were higher.(Miyamoto and Hara 1988),• Highest returns/m2 with a combination of 2stems/plant.

Fruit and shoot borer• Tiny larvae enter terminal shoots – wilting & drooping infected fruit – bore holes + plugged excreta
• Bore leaf axil & main stem cover excreta & Frass. Young shoots wither & older plants stunted.
Remove and destroy the affected tender shoots, fallen fruits and fruits with bore holesAvoid continuous cropping of brinjal cropResistant varieties: Annamalai and Pusa purple roundGrow the varieties with long and narrow fruits in endemic areasBacillus thuriengiensis var. kurstaki @ 1500 ml/ ha (750 lit of spray fluid)Encourage the activity of larval parasitoids:
Pristomerus testaceusCremastus flavoorbitalisShirakia schoenobiiBracon greeni
Egg parasitoid:Trichogramma chilonis @ 50,000/ ha, four times from 30 DAT at 20 days interval
Stem borer
Epilachna (Hadda) beetle• Scrape & stripped to
mid-veins –skeletons. Feed fruits hollow fruit surface.
Jassids
• Control by malathion 0.1%• Locate
resistant varieties Arka Shirish
• Suck lower leaves. Infected plants pale & finally bronze. Transmit little leaf. Leaves cup-Shaped.
Control • Spray carbaryl
0.1% or Dimethoate 30 % EC 7ml/10litre of water
White fly• Hot and dry
conditions.• Suck the plants, turn
yellow – honey dew – sooty mould
Control• yellow sticky trap @
12/ha. Spray Neem oil 3% plus Teepol 1 ml/lit or spray NSKE 5 %
Cpg horti – 2013
Aphids• Suck sap. Leaves
curl, fade, & dry up in severe.
Spider mites Control • Dicofol 18.5 EC
@ 2.5 ml or any other acaricide like wettable sulphur 75 WP @ 3 g/l.• neem
soap/pongamia soap 1% on the under surface of the leaves
• 1st instar larvae of Green lace wing predator (Chrysoperla carnea) @ 10,000/ ha. • Phosphamidon 40 %
SL 1.5 ml/lit.
• White specks – silken webs – leaves drying in severe -
Leaf roller Larva fold leaves – tip to downwards – scrapping green matter and dry up.
Leaf minor• Larva mines into
the veins of leaves, midribs, leaf stalks – resulting in gall like swelling and blotches near leaf tips
Bud worm• bore inside flower
buds & feed. Shriveling, low fruit set and prevents fruit formation drop off.
Integrated Pest Management Strategies for Brinjal - National Centre for Integrated Pest Management(ICAR) Pusa Campus, New Delhi
• Bird perches @ 10/ acre - field visits of predatory birds.•Delta and yellow sticky traps @ 2-3/ acre - hoppers, aphids and white fly etc.•Give 2 to 3 sprays of 5 % NSKE against sucking pests. Sprays of NSKE also bring down the borer incidence significantly. • Neem oil (2%) also reducing borer infestation, marginally. If incidence of leaf hopper and other sucking insect pests is still above ETL, then apply imidacloprid 17.8 SL @ 150 ml/ha.• Pheromone traps @ 5/ acre should be installed for monitoring and mass trapping of shoot & fruit borer Leucinodes orbonalis. Replace the lures with fresh lures after every 15-20 day interval.• Release egg parasitoid Trichogramma brasiliensis @ 1 – 1.5 lakh/ ha for shoot & fruit borer, 4-5 times at weekly interval.
Conti….• neem cake @ 250 kg/ ha (in two splits) in soil along the plant rows at 25 and 60 DAT for reducing nematodes and borer damage. Don’t apply neem cake when there is heavy wind velocity or temperature is above 30˚C.• Clipping of borer damaged shoots and collection & destruction of damaged fruits i.e. clean cultivation helps in management of borer and phomosis disease effectively.• If the borer incidence crosses ETL (5% infestation), apply cypermethrin 25 EC @ 200 g a.i/ha (0.005%) or carbaryl 50 WP @ 3 g/litre of water. Continuous cropping of Brinjal leads to more borer and wilt infestation. Therefore, crop rotation with non solanaceous crops should be followed.• Periodically collect and destroy the egg masses, larvae and adults of hadda beetle.• Rogue out the little leaf affected plants from time to time.• Use of green manure, mulching with polythene, soil application with bleaching powder will reduce the infection of bacterial wilt disease.
• Only healthy, uninfected seedlings should be transplanted to the field.
• If the seedling nursery is close to an infected field, EFSB may lay eggs on the seedlings before transplantation.
• Seedlings can be grown under netting to ensure there is no Infestation.
