In India, oilseed Brassica are grown over an area of about million hectares with an annual production of million tones with an average yield of 1304 kg/ha whereas in Rajasthan it was still 1422kg/ha. The severe attack of many diseases not only deteriorates the quality of the seed, but also reduces the oil content considerably. Among the diseases, white rust caused by Albugo candida (Pers. Ex Hook) O. Kuntze, is an important disease of a wide variety of Brassica crops. Its infection causes disfiguring white pustules on leaves, flowers stems and pod leading to yield losses. |
