Inhibition of mosaic virus of Vigna sinensis Endl. with four chemicals

Four chemicals--gibberellic acid, indoleacetic acid, 2,4-6 and thiouracil were tested for their inhibitory effect against a virus disease of Vigna sinensis (cowpea). All the four chemicals inhibited the virus to a considerable extent in in vitro studies. Pre and post-inoculation treatments were equally effective in inhibiting the virus, viz. local lesion formation on Chenopodium amaranticolor leaves. The level of inhibition subsequently decreased with lower concentration of the chemicals. Seed soaking in the chemicals controlled the virus infection.
