Effect of Rotylenchulus reniformis on Groundnut in presence or absence of Rhizoctonia bataticola

The interaction between reniform nematode Rotylenchulus reniformis and dry root rot fungus Rhizoctonia bataticola was studied on groundnut cv. M-13 under glass house conditions. The effect of the nematode in combination with the fimgus enhanced the suppression of plant growth characters. Maximum reduction in plant shoot weight (35.33 g) was observed when nematode was inoculated one week prior to fimgus. The nematode reproduction rate was also observed to be lowest (4.64), when nematode and fungus inoculated simultaneously.
