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)
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)
Loopers and Borers Veracious eaters on leaf.
Control: Chlorphyriphs 50% + Cypermethrin 5% w/w (2ml/L), Emamectin Benzoate 5% SG (1g/L)
Aphids Suck the sap from leaves cause leaf distortion.
Control: Acephate 20 SP% (1g/L)
White Fly Suck the sap from leaves cause leaf distortion.
Control: Diafenthiuron 40.1 % + Actamiprid 3.9 % WP @ 1.5 gm /ltr

Parameter Description
Riceyness It manifests in the elongation on peduncle wearing flower buds, rendering curds granular, loose and somewhat velvety. A premature initiation of floral bud is characterized by riceyness in cauliflower and is considered to be of poor quality for marketing. It can be controlled by cultivation of appropriate varieties and following proper season with recommended cultural practices.
Fuzziness It appears as the flower pedicels of velvety curds elongate. The anomaly is both hereditary and non-hereditary. Cultivation of cauliflower, out of their normal season encourages fuzziness. Sowing good quality seed in right season under proper cultural practices, minimizes fuzziness.
Leafiness / Bracting This disorder is commonly seen by formation of small thin leaves from the curd which reduces quality of curd. Extremely small green leaves appear in between the curd segment due to inheritable or non-heritable factors. Prevalence of high temperatures during curding phase aggravates leafiness. Certain varieties are more sensitive to leafiness or bracketing than other. It can be controlled by selection of varieties according to their adaptability.
Browning (Brown Rot or Red Rot) It is caused by boron deficiency which is influenced by soil pH. The availability of boron decreases at neutral soil reaction. It is characterized by sign on the young leaves that become dark green and brittle. The old leaves puckered, chlorotic and often drops off. This may be controlled by application of borax or sodium borate or sodium tetra borate at the rate of 20 kg/ha a soil application. In case of acute deficiency, spray of 0.25 to 0.50 per cent solution of borax at the rate of 1 to 2 kg/ha depending upon growth, soil reaction and extent of deficiency.
Whiptail Deficiency of molybdenum causes ‘whiptail’ syndrome, especially, in highly acidic soils. Because high manganese concentrations in such soils hinder the uptake of molybdenum which seldom occurs when the soil pH is 5.5 or higher. The young cauliflower plants become chlorotic and may turn white, particularly along the leaf margins. They also become cupped and wither. and extent of deficiency. In older plant, the lamina of the newly formed leaves are irregular in shape, frequently, consisting of only a large bare midribs and hence, the common name “whiptail”. It can be corrected by application of lime or dolomite limestone to raise the soil pH up to 6.5 or higher. Sodium or Ammonium molybdate at the rate of 1-2 kg/ha as soil application can also control “whiptail” of cauliflower.
Buttoning Development of small curds with inadequate foliage in cauliflower is known as buttoning. It is also referred to as premature heading. The leaves are so small that cannot cover the formed head. The curds are non marketable and often malformed and lacks color or compactness .It can be be controlled by using quality seedlings and proper cultural management practices.
