Detail:

After transplantation to the field from seedling pan, it is commonly observed that a number of chilli (Capsicum annuum) saplings develop wrinkles in their leaves. This disease is more pronounced in the winter crop, particularly in the months of January and February. The disease first affects the leaves and then the branches of the plant, which become badly curled. When this happens, either the plant wilts away or fails to produce the usual number of fruits. Sakhia who resides in a farmhouse had a guest one day and to entertain the guest, he got some fresh limejuice prepared. A lizard happened to fall in the utensil and the drink had to be thrown away. He poured the juice in a bucketful of water before throwing out and the contents fell on chilli plants nearby. Most of the plants, which had been affected by wrinkle and wilt disease then, were found after a few days to have become healthy. This gave him the idea of using dilute lime juice as a cure for the disease. Dilute the juice squeezed from 500 g of lemon (Citrus limon) fruits with 10 l of water.

"The virucidal activity of many organic acids against the type species of some viral groups (Herpesvirus, Orthomyxovirus, and Rhabdovirus) has been evaluated.The results thus obtained suggest that the activity of the different chemical compounds essentially depends on the functional groups present in the molecule.Some hypotheses on the way in which organic acids can inhibit cellular infection caused by enveloped viruses are also suggested."

"This study was done to investigate antiviral activity of four plants. For this purpose, the extracts of four plants were ready and adjacent to virus. EID50 of virus and virus/extract was calculated for any plant by Reed and Muench method. Antiviral activities were calculated as the difference of virus titer between treated and untreated infected control eggs and expressed by inhibition percentage (IP). The results of this test showed Limon had the most antiviral activity and could reduce viral pathogenicity of NDV as 100 fold. Matricariarecutita L., Allium ascalonicum L. could reduce activity of virus as 3.8 and 40.5 fold respectively, but Rosa damascene did not have any significant effect on virus. Accordingly, three out of four of these extracts were found effective." [Rezatofighi, SeyedehElham&Ebrahimian, &Lordifar, &Mehravar, Neda&Sirnejad,. (2014).
