What are the symptoms of Fusarium Wilt in cotton ?

Fusarium wilt results in stunted plant growth , yellowing of plants and defoliation. Yellowing starts in the edges of leaves and then move inwards. Brown discoloration occurs in stems which is more intense in outer layer of tissues. Infected plants fruit earlier and produce smaller boll. In seedlings and young plants, cotyledons and leaves wilt, may turn necrotic, and even fall off the plant, resulting in bare stems. In mildly affected plants, lower leaves develop symptoms but plants survive, but with reduced vigor and noticeable stunting.
