Influence of Temperature on Encumberance of Pasteuria penetrans Spores and its Efficacy on Biocontrol of Meloidogyne javanica


Abstract

The bacterial spores of Pasteuria penetrans more readily encumbered on Meloidogyne javanica at 30° and 25.50°-34.0°C than at 10° or 20°C. Application of the bacterial spore powder to soil resulted in significant increase in growth characters of tomato plants. There was 37.20, 23.41, and 40.56 per cent increase in fresh and dry weight of shoot and fresh weight of root. respectively. and 78.1 per cent reduction in total nematode population at a concentration of 600 mg spore powder per kg of soil.
