Brassica juncea, the Indian mustard supplies a big amount of edible oil demand in India. Biotic and Abiotic factors were responsible for serious reductions in B. juncea production in India. Several control measurements had been taken to prevent the losses in crop. Biochemical control, Biological control and Genetic control are some of the preventive methods used in this study to evaluate the yield loss in Indian Mustard. In India around 39 million hectares of land was under mustard cultivation with a production of 10 million tonnes. It was estimated that the demand for oilseed in India will be around 34 million tonnes by the year 2020. 41% of this demand (14 million tonnes) had to be met by mustard alone. Apart from its use as oil, it has got some medicinal properties too. Among the oilseed crops grown in India, mustard (Brassica sp.) was one the most important ones. In India around 26.11 million hectares of land was under mustard cultivation during the year 2009-2010 (4 th advanced estimates released on 19.07.2010 by Ministry of Agriculture, Govt. of India). It was estimated that the demand for oilseed in India will be around 34 million tonnes by the year 2020. 41% of this demand 14 million tonnes must be met by mustard alone. The production of Indian mustard was severely affected by mustard aphids. In this review, we had studied some of the control method to avoid aphid infestation, which will severely affect the crop production.
