Cottony rot

Caused by: Sclerotinia sclerotiorum
Problem Category: Fungal Disease
Symptoms: Small, water-soaked, soft lesions on crown and roots; white fluffy fungal growth all over affected tissues; soft and decaying tissue developing
Comments: Fungus can survive in soil for up to 10 years; disease emergence is favored by soils that are held close to saturation for periods in excess of 2 weeks
Management: Cultural practices play an important role in the control of cottony rot as there are no resistand carrot varieties: in carrot fields, the use of drip irrigation 5-8 cm below the soil surface can provide good control; deep plowing of soil and trimming back carrot foliage to promote air circulation can also be useful; fungicides may be warranted in periods of extended cool, damp weather
Control: spray 2 times Cowdung+Asafoetida solution in 10 days interval to control blight
