Abstract:

Brown spot of rice caused by Drechslera oryzae and rice root-knot nematode caused by Meloidogyne graminicola are serious pest of rice and has become a major constraint in rice production throughout the world. A lab experiment was conducted in Laboratory of the Department of Plant Pathology, SHUATS, Prayagraj, and U.P. during 2018-19 to observed the effect of botanicals viz against Drechslera oryzae and Meloidogyne graminicola of rice. In vitro the selected botanicals Neem, Ashoka, Moringa, Aloe vera, Hibiscus, Curry leaves and Lantana leaf extracts 10% against Drechslera oryzae were tested in food poisoned technique to see the effectiveness. Radial growth (mm) was recorded at 24, 48 and 72 hrs after exposure in the treatments. Among the treatments of botanicals Neem leaf extract shows significant reduce in radial growth of Drechslera oryzae at 24 hrs (7.93), 48 hrs (14.57), and 72 hrs (23.23) as compared with control (18.80, 29.20, 40.73). In the pot experiment infected rhizospheric soil of 2000 larvae/pot (500 gm soil) were filled in plastic pots and selected botanical leaf extracts incorporate the 100 gm of leaves in 100 ml of water (w/v) extracts were superintend in each treatment of four replications for the control of root-knot population of Meloidogyne graminicola of rice. Nematode populations of plants were recorded at 40 days after exposure of the treatments. Among the treatments root-knot population (Meloidogyne graminicola) Aloe vera (7) and Ashoka (7) shows significantly reduced of Meloidogyne graminicola population as compared to control (24). Based on the findings it was concluded that Neem leaf extract was proved to be most effective against Drechslera oryzae and Aloe vera, Ashoka were proved to be most effective against the root-knot population of Meloidogyne graminicola.
