Diseases

Name of the diseases

Symptoms & management

Black Rot

First signs of the disease often appear along the margins of leaves as chlorotic regions and the chlorosis progresses in the direction of the mid rib forming a V shaped area. Symptoms may appear from any side and centre of the leaves. The bacteria are transmitted through seeds.  

Control: use of disease free seeds, use of resistant hybrids

spray of Copper Oxy Chloride 50% Wp + K Cycline (2.5g + 0.5g/L)

Leaf blight 

Pin-sized black specks found on the leaf surface or stem. The specks enlarge concentrically, creating a distinct target spot or bull’s eye lesion with a yellow halo. 

Control: Fluxapyroxad 250 G/L + Pyraclostrobin 250 G/L  SC 0.3 ml/L

Downy Mildew

Small brownish spots on leaves, on lower surface whitish powdery mass observed at cloudy weather, cause defoliation

Spray: Fenamidone 10% + mancozeb 505 WG (2.5g/L)

Metiram 55% + Pyraclostrobn 5% WG (2g/L)

Black leg

On seedlings black pucnidea as visible as small dots on hypocotyl and in the advance stages the stem shows greyish brown whole spots often with purple and black margin

Control : COC @ 2 gm / ltr, Streptocyclin 0.5 gm /ltr, Thiophenate methyl @ 2 gm / ltr

Pests

Name of the pests

Symptoms & management

DBM

DBM causes damages to leaves by making wholes on leaves cause severe damage

Control: Chlorantraniliprole 18.5% SC (0.3ml/L)

Spinosad 45% SC (0.15ml/L)

Pheromone traps with lures @ 30 traps /ha

Borers & Loopers

Control:  Chlorphyriphs 50% + Cypermethrin 5% w/w   (2ml/L), Emamectin Benzoate 5% SG (1g/L)

Pheromone traps with lures @ 30 traps /ha

Aphids

Suck the sap from leaves cause leaf distortion

Control: Acephate 20 SP% ( 1g/L)

Flea beetle

Scrap the chlorophyll content of the leaf and skeletonize the leaf

Control :  Spinosad 45% SC (0.15ml/L), Bifenthrin 10 % EC @ 1.5 ml/ltr

Cabbage Butterfly

Adult butterflies lay eggs on the under surface of the leaves , upon hatching the caterpillar feeds on the leaves causing stunted growth

Control :  Chlorphyriphs 50% + Cypermethrin 5% w/w   (2ml/L), Emamectin Benzoate 5% SG (1g/L)

Pheromone traps with lures @ 30 traps /ha

Harvesting

Harvesting is done when the heads are well developed and firm, usually ready by 55-60 days after transplanting

Yield
