Leaves Of Seedlings Of Rice (Oryza Sativa) Becomes White In Colour
About the Practice
When leaves of seedlings of paddy (Oryza sativa) becomes white, use tobacco (Nicotiana tabacum) powder for protection. After 25 to 30 days of plantation of seeds of rice, seedlings of rice (Oryza sativa) had white coloured leaves, leads to retardation of growth consequently loss to in yeild. 500 g tabacco (Nicotiana tabacum) powder per 10 x 10 m plot areas is sprinkled to protect plants against this disease condition. Other farmers also use this treatment for betterment of their rice crops.

PAS 1:
"Nicotiana tabacum L., used at the concentration of 2 mg/ml, showed the highest corrected mortality (92.0%) with a lethal time (LT50) value of 12.9 h. The extract was followed in its efficacy by Allium sativum L. (88.0%), Zanthoxylum piperitum (L.) De Candolle (70.0%), and Sapindus mukorossi Gaertner (65.0%), when mortality was assessed at 20 h after exposure. Against adult fruit moths (< 5 d old), N. tabacum also showed the highest corrected mortality among tested extracts, being 85 and 100% in adult females and males, respectively, at 168 h after exposure. However, there was no synergistic effect of the combined application of any of the top four extracts in either laboratory or greenhouse assays. Oviposition by G. molesta on peach twigs was reduced 85–90% when N. tabacum was applied at 4 ml/ twig compared to control (methanol), demonstrating that N. tabacum may have potential for use as a botanical insecticide against G. molesta.
