Powdery mildew of Pea is caused by
- Erysiphe
- Puccinia
- Alternaria
- Ustilago
The Correct Option is A
Solution and Explanation
It is caused by Erysiphe. Powdery mildew of pea is a fungal disease that affects the pea plant. There will be reduction in the plant health, stunted growth and decreased pea yield. They thrive in humid conditions and moderate temperatures. The leaves that are infected may curl, distort and become yellow that leads to the reduction in the photosynthesis.
So, the correct answer is (A): Erysiphe

Biological Classification
The process of grouping living organisms into categories is called biological classification. The most modern 5-kingdom classification was put ahead by an eminent scientist R.H.Whittaker. The five-kingdom classification is based on the criteria like cell structure, mode of nutrition, body form, and reproduction. One of the most important characteristics of this system is that it follows the evolutionary sequence of living organisms. The organisms are classified into distinct taxa or levels like Kingdom, Phylum, Division, Class, Order, Family, Genus, and Species. The 5 kingdoms are as follows:
