Diseases
Name of the Disease 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% + Pyraclostrobin 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 Pest 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 Veracious eaters on leaf.
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 75-80 days after transplanting
Yield 35-40 t/ha
Parameter Description
Tip Burn Brown or necrotic spots at the tips and margins of inner leaves within the head linked with calcium deficiency and excessive nitrogen and phosphorus.
Control: Ensure adequate calcium supply through soil amendments or foliar applications, and manage nitrogen and potassium fertilization accordingly.
Splitting / Cracking Cracks or splits appearing on the head due to rapid growth, high humidity, and excessive water pressure within the head can lead to splitting.
Control: Avoid excess irrigation and fertilizers.
Blindness Loss of inner leaves within the head, leaving only the outer leaves due to low and high temperature.
Control: Regulate temperature in the nursery. In case of raised bed nurseries, provide adequate irrigation and shade.
Wiry Stem Elongated hypocotyls in seedlings and in mature seedlings hard stems and lesser leaves caused by excess temperature.
Control: Regulate temperature in the nursery. In case of raised bed nurseries, provide adequate irrigation and shade.
