Question

Wheat paddy and sugarcane generaly are susceptible to what diseases

Answer 1

The spindle leaves (3rd & 14th)) display drying. At a later stage, stalks become discoloured and hollow.

Acervuli (black fruiting bodies) develop on rind and nodes. After splitting open the diseased stalk, a sour smell emanates.

The internal tissues are reddened with intermingled transverse white spots.

Survival and spread

In rainy season, the disease spreads so fast that whole crop dries and not a single milleable cane is obtained

Favourable conditions

Primary transmission through soil and diseased setts, while the secondary transmission through air, rain splash and soil.
