Solution(By Examveda Team)

The appearance of root knots in mulberry is due to Nematodes.
The pathogenic nematode overwinters in the affected roots. During the following spring, the second stage larva infests the mulberry roots and causes the formation of root knots. The root-knot nematode moves slowly in the soil, thus by their active movement the spread of disease is limited.
