Details of Innovation	Diseases of chilli have posed a serious threat in Jodhpur district. A major disease that causes considerable loss in yield is the leaf curl mosaic virus (LCV). The characteristic symptoms of LCV are bright yellow mosaic, leaf rolling, distortion and puckering, reduction in leaf size and stunting of the affected plant. The white fly (Bemisia tabaci Genn)-transmitted gemini virus are the causal organisms of this disease. Gemini viruses in chilli are difficult and expensive to manage. The only strategies available are to spray insecticides or use virus-resistant crop varieties. The seeds of the cultivar, Mandoria were treated with raw cow milk for 24 hours. The seeds were dried and then sown to raise nursery plants. The roots of the seedlings were dipped in milk before transplanting them on the field. In the field, milk was sprayed at intervals of 10 days. The incidence of LCV on the cow milk-treated plants and plants with other treatments along with a control field were tested. The results indicated that in the milk-treated plants, incidence of LCV was recorded at its lowest (30.7 percent) when compared with other treatments. The cow milk treatment controlled the disease by 34 percent. An increased average fruit size, 15.3 cm per plant was also noticed.

PAS_1	"Fruit juice of C. limon, inhibited clinical isolates of Staphylococcus aureus, Escherichia coli, Klebsiellaaerogenes, and Klebsiellapneumoniae.[32] Peel extracts of C. sinensis have marked antibacterial action while C. aurantium revealed higher antifungal activity against Colletotrichumcapsici in comparison with each other.[33] Aqueous extracts of peel and juice from fresh and dried Citrus and sweet lemon reported antimicrobial action against six Gram-positive and eight Gram-negative bacterial and one yeast isolates.[34] C. sinensis seed oil is highly effective as an antifungal agent against Lentinussajor-caju, which causes white rot in wood hence, it can be used as a preservative agent in the management of wood infected with white rot fungi.[35] Propionibacterium acnes, bacterial species that causes Acne vulgaris is reported to be very sensitive to C. limon.[36] Methanolic extract of C. sinensis fruit peel was able to inhibit all the bacteria [Chaudhari, Swapnil&Ruknuddin, Galib&Prajapati, Pradeep.
