verticillium wilt verticillium dahliae is now a days commonplace in olive orchards in north of iran. root-knot nematode, meloidogyne javanica, as well is one of the most widely disseminated plant parasitic nematodes in olive orchards of iran. this study was arranged to find the effects of two sets of pot beds on these pathogens' interaction. microsclerotia of verticillium dahliae and j2s o...

This study was conducted in 2020 to investigate the influence of melatonin (10, 50 and 100 µM) given three methods (immersion, irrigation, foliar spraying) on some physiological aspects tomato seedlings inoculated with root-knot nematode Meloidogyne incognita [(Kofoid White) Chitwood]. The were 1000 second-stage juveniles M. incognita. Dualex® optic sensor used situ measure total chlorophylls, ...

The effects of pre-planted marigold on tomato root-galling and multiplication of Meloidogyne incognita, M. javanica, M. arenaria, and M. hapla were studied. Marigold cultivars of Tagetes patula, T. erecta, T. signata, and a Tagetes hybrid all reduced galling and numbers of second-stage juveniles (J2) in subsequent tomato compared to the tomato-tomato control. All four Meloidogyne spp. reproduce...

Meloidogyne incognita, the root-knot nematode (RKN), a devastating plant parasitic nematode, causes considerable damage to agricultural crops worldwide. As sedentary root parasite, it alters root’s physiology and influences host’s phytohormonal signaling evade defense. The sustainable management of RKN remains challenging task. Hence, we made an attempt investigate nematicide activity Bacillus ...

Tomato (Solanum lycopersicum L.) is one of the most important vegetables worldwide. productivity limited by, among other factors, biotic constraints including root-knot nematodes (Meloidogyne species) which lower both quality and quantity crop. Two trials were conducted at Horticulture Research Teaching Field, Egerton University, Kenya, to evaluate effects fresh organic manure slender leaf (Cro...
