“…Tulsi is preeminent medicinal plant and scientific research is now confirming its beneficial effects (Cohen, 2014). Dheeba et al (2015) published that tulsi leaf extract is effective against early blight of tomato. In a previous study, it was found that Thankuni and Nishinda were effective plant extracts inhibiting Fusarium caerulium causing dry rot disease of potato (Rifat, 2014).…”

Aqueous extract of some indigenous plant parts were evaluated for its efficacy to control sheath blight of rice. Six treatments were applied, viz. T1-control (water spray), T2-Tulsi (Ocientific tenuiflorum) extract (1:10), T3-Nishinda (Vitex negundu) extract (1:10), T4-Thankuni (Centella asiatica) extracts (1:10), T5-Biskatali (Polygonum hydropiper) extract (1:10) and T6-Proud (Propiconazole @ 0.2%) as a positive control. Effect of these plant extracts on percent tiller infection and percent relative lesion height of sheath blight of rice cultivar BRRI dhan 49 was determined at 55, 75 and 95 day after transplanting (DAT). Number of infected tillers per hill differed significantly among the different treatments. The highest number of infected tillers was observed in control treatment. The lowest and statistically similar number of infected tillers was found in fungicide, Proud (Propiconazole)-and Biskatali-treated plots. Reduced number of infected tillers was observed in Tulsi, Thankuni and Nishinda. Highest percent tiller infection was recorded in control and lowest percent tiller infection was recorded in Proud and Biskatali, which were statistically similar. Nishinda, Tulsi and Thankuni had reduced tiller infection in compare to control. Percent reduction of tiller infection over control was achieved by proud followed by Biskatali. The highest lesion height was observed in control and lowest lesion height was found in Proud followed by Biskatali. The highest percent relative lesion height was recorded in control followed by Thankuni. The lowest percent relative lesion height was recorded in Proud preceded by Biskatali. Highest percent reduction of relative lesion height over control was achieved by proud followed by Biskatali. Thus, plant extracts of Biskatali, Tulsi, Nishinda and Thankuni are effective to control sheath blight of rice. Among the plant extracts, Biskatali showed highest control of sheath blight disease of rice.

“…Preventive fungicides and botanicals inhibit the spore germination and penetration but pathogen can derive resistance against fungicide application so repeated application of fungicides at proper dose and interval of time is mandatory (Hossain and Hossain, 2009;Kumara et al, 2010). Application of fungicides and botanicals against early blight has been reported in India by various workers (Arunakumara et al, 2010;Dheeba et al, 2015). Unplanned and wide use of fungicides often leads to serious environmental problems besides affecting the health of users and consumers.…”

“…31 Foliar treatment of tomato plants with 30% aqueous extract of O. sanctum increased the antioxidant enzymes. 32 Drought triggers a variety of response at molecular level, by modifying a range of genes expression. Among various genes, aquaporins and dehydrins play a major role in providing drought tolerance in plants.…”

Ocimum leaves are highly enriched in antioxidant components. Thus, its leaf extract, if applied in plants, is believed to efficiently scavenge ROS, thereby preventing oxidative damage under drought stress. Thus, the present study was performed in kharif 2013 and rabi 2014 season to evaluate the effect of aqueous leaf extract of Ocimum sanctum against drought stress in 2 rice genotype under glass house conditions. Here we show that various morpho-physiological (chlorophyll fluorescence, leaf rolling score, leaf tip burn, number of senesced leaves and total dry matter) and biochemical parameters (proline, malondialdehyde and superoxide dismutase content) were amended by Ocimum treatment in both the seasons. Application of Ocimum extract increased expression of dehydrin genes, while reducing expression of aquaporin genes in drought stressed rice plant. Thus, application of Ocimum leaf extract under drought stress can be suggested as a promising strategy to mitigate drought stress in economical, accessible and ecofriendly manner.
