Efecto del blasticidin en el control del virus del mosaico del tabaco
The inhibiting effect of Blasticidin on Tobacco Mosaic Virus (TMV) was studied Doses of 10, 1, 0.1 and 0.01 ppm were used to estimate the amount of product useful to determine inhibition of the virus. The product was applied 1o the upper leaves, lower leaves and the soil, before, simultaneously and after inoculation with TMV. The toxicity of the product was taken into account as well as its translocation inside the plants The time of application, doses and place of application of the product were not Statistically different, the possible preventive or curative actions were the same with the different doses and in the different places of the plant. The most effective treatments to inhibit TMV on Nicotiana glutinosa without plant toxicity were Blasticidin post inoculated at 0.1 ppm on lower leaves with a mean of 12.18 fewer local lesions than the controls, and Blasticidin pre inoculated at 01 ppm on upper leaves with a mean of 7.68 fewer local lesions than the control. Although other higher doses inhibited infection by the virus, the degree of plant toxicity produced made them not useful. Nine of the 24 treatments resulted in inhibition of TMV The translocation of the product was in both directions up and down. The plant toxicity of this product was evident in the major necrosis produced on the tobacco leaves and its use for inhibition of TMV should be considered only at the experimental level.
