Whiptail disease of cauliflower plants is caused by deficiency of(a) Mo
(b) B(c) Fe
(d) Ni

Answer 1

Answer:

A) Mo

Explanation:

Whiptail disorder is caused due to deficiency of molybdenum. In young plants the deficiency symptoms are chlorosis of leaf margins and the whole leaves may turn white. The leaf blades do not develop properly. When the deficiency is severe, only the midribs develop. This condition is commonly known as 'Whiptail'. 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.
