Biocontrol Efficacy of Formulated Pseudomonas chlororaphis O6 against Plant Diseases and Root-Knot Nematodes.

摘要: Commercial biocontrol of microbial plant diseases and pests, such as nematodes, requires field-effective formulations. The isolate Pseudomonas chlororaphis O6 is a Gram-negative bacterium that controls pathogens both directly indirectly. This also has nematocidal activity. In this study, we report on the efficacy wettable powder-type formulation P. O6. Culturable bacteria in formulated product were retained at above 1 × 108 colony forming units/g after storage powder 25 °C for six months. Foliar application diluted controlled leaf blight gray mold tomato. displayed preventative curative root-knot nematode (Meloidogyne spp.) Under laboratory conditions commercially grown melon, control was levels comparable to standard commercial chemical nematicide. results indicated can be used nematodes.
