Epidemiological Studies and Management of Urdbean Leaf Crinkle Virus

Judicious use of fertilizer is a serious feature in allowing crops to recognize their full yield potential. It is an unfriendly and expensive practice to use chemicals against vector. The resistance of plants to diseases is mainly related to genetics. However, the ability of the plant to express its induced resistance to a particular disease is affected by mineral nutrition. Nutrient elements either single or combined application of boron with zinc had significant effect in reducing viral diseases in winter mungbean. It appears that resistance or tolerance of plant is metabolically boosted up by the application of nutrients. Use of resistant crop varieties is regarded as an economical and durable method for controlling plant diseases especially those caused by viruses. Epidemiological factors play an ideal role in the development of ULCV.
