Whiptail disorder is caused due to deficiency of molybdenum (Mo). A farmer or anyone related to the field can easily track the disorder studying particular symptoms shown by cauliflower leaves.
Symptoms:
1. Chlorosis of leaf margins occur in young plants, and the whole leaves may turn white.
2. The leaf blades of the plant do not develop properly.
3. When the deficiency is severe, only the midribs develop. This condition is commonly known as 'Whiptail'.
4. The growing point of the plant is also deformed which prevents the curd development.
The deficiency of molybdenum generally occurs in acid soils when the soil pH is below 5.5.
The deficiency of molybdenum generally occurs in acid soils when the soil pH is below 5.5.
Solution: Lime application in acidic soils is done to increase the availability of molybdenum.
Soil application of Sodium Molybdate (10-15 kg/ha) effectively controls the deficiency symptoms.
