Fungal Disease

The wet cloudy weather at planting was fairly conducive to wet weather blight, particularly for some planting dates. Wet weather blight is caused by ascochyta fungus.

Notice that the new leaves look healthy and the symptoms are limited to the cotyledons and older leaves .

Cotton Small, round, whitish spots (up to 2 mm diameter) first appear on the cotyledons and lower leaves of seedlings.  Early plantings may be stunted.Conidiomata are produced in abundance in the older parts of lesions or after the leaves and stalks are dead. 

Leaf lesions may develop more frequently on the midrib, causing it to fracture. Lenticular, dark spots may be found on the stem (Holliday and Punithalingam, 1970).
