Abstract
Abo-Elyousr, Kamal A., Zakaullah Khan, Magd El-Morsi Award, and Montaser Fawzy Abedel-Moneim. 2010. Evaluation of plant extracts and Pseudomonas spp. for control of root-knot nematode, Meloidogyne incognita on tomato. Nematropica 40:289-299. Fresh leaf extracts of Azadirachta indica (neem), Allium sativum (garlic) and Tagetes erecta (African marigold) and bacterial suspensions of Pseudomonas fluorescens and P. aeruginosa were tested against Meloidogyne incognita on tomato under in vitro, pots and field conditions. All treatments immobilized juveniles (J2); with the highest effect caused by neem leaves extract and the lowest by P. aeruginosa after 24 h and 48 h of exposures. In soil all treatments significantly reduced root galling, nematode population, and enhanced plant growth and yield, with bacterial treatments being the most effective. Nematode populations were reduced greater by nematicide (Vydate 10 G) treatment but the greatest increase in yield (67%) was obtained with P. fluorescens; the treatment reduced root galling by 68-70% and 48% in pot and field experiments, respectively. Among the plant species, garlic demonstrated best control reducing root galls by 57% in pots under greenhouse and 33% in field conditions and increasing fruits yield by 47%. Abo-Elyousr, Kamal A., Zakaullah Khan, Magd El-Morsi Award and Montaser Fawzy Abedel-Moneim. 2010. Evaluacion de extractos de plantas y de Pseudomonas spp. para el control de Meloidogyne incognita en tomate. Nematropica 40:289-299. Se probaron extractos frescos de hojas de Azadirachta indica (nim), Allium sativum (ajo) y Tagetes erecta (clavelon africano) y suspensions bacteriales de Pseudomonas fluorescens y P. aeruginosa para el control de Meloidogyne incognita en tomate in vitro, en macetas y en campo. Todos los tratamientos inmovilizaron los juveniles (J2); observandose el mayor efecto con el extracto de hojas de nim y el menor con el extracto de P. aeruginosa despues de 24 y 48 h de exposicion. En el suelo, todos los tratamientos redujeron significativamente el agallamiento y la densidad de poblacion del nematodo, y aumentaron el crecimiento y rendimiento de la planta, siendo los tratamientos bacteriales los mas efectivos. La mayor reduccion en las poblaciones del nematodo se observo con el tratamiento con nematicida (Vydate 10 G), pero el mayor aumento en rendimiento (67%) se obtuvo con P. fluorescens; cuyo tratamiento redujo el agallamiento en 68-70% y 48% en macetas y campo, respectivamente. Entre los tratamientos vegetales, el ajo demostro el major control de agallamiento, con una reduccion del 57% en macetas y 33% en campo, y un aumento del rendimiento del 47%.
