Host Suitability of Soybean Cultivars for Meloidogyne incognita and M. arenaria.
The suitability of five maturity group (MG) III and five MG IV soybean, Glycine max, cultivars as hosts for Meloidogyne incognita and M. arenaria was evaluated in a greenhouse. 'Forrest', a MG V cultivar, was used as the standard of comparison for M. incognita resistance. With M. incognita, root-gall and egg-mass indices and reproductive factors for 'Asgrow 3307', 'FFR 398', and 'Pioneer 9442' ...
متن کاملExpression of Resistance to Meloidogyne incognita in Kenaf Cultivars (Hibiscus cannibinus) under Field Conditions
Field studies were conducted in 2003 and 2004 to investigate the reaction of 10 varieties of kenaf to natural infestation of Meloidogyne incognita. Ten weeks after planting, ten randomly selected plants per variety were assessed for root galling. Plants were carefully uprooted soil adhering to roots was washed off under a gentle stream of tap water and roots then were observed using a stereo mi...
متن کاملTrichoderma harzianum reduces population of Meloidogyne incognita in cucumber plants under greenhouse conditions
Trichoderma harzianum strain ESALQ-1306 was assessed for its potential biological control against Meloidogyne incognita race 4 under in vitro and greenhouse conditions. In vitro, we noticed 64% of conidial attachment on eggs and second-stage juvenile immobilized by the fungus. In greenhouse, cucumber plants were treated with different concentrations of conidial suspensions before and after inoc...
متن کاملHost Suitability of Commercial Corn Hybrids to Meloidogyne arenaria and M. incognita.
The host suitability of 64 commercial corn hybrids for a Meloidogyne arenaria race 2 population and a M. incognita race 4 population was determined in greenhouse experiments. 'Northrup King 508' and 'Pioneer Brand 3147' maintained M. arenaria below and at the initial population level, respectively, indicating that these hybrids are relatively poor hosts for this species. RF values (final egg nu...
متن کاملReaction of Trifolium repens Cultivars and Germplasms to Meloidogyne incognita.
Ten cultivars and 13 germplasms of white clover (Trifolium repens) were evaluated in the greenhouse for resistance to the southern root-knot nematode, Meloidogyne incognita race 4. One hundred plants of each cultivar or germplasm were rated for percentage of the root system galled (PRSG) at 60 days after inoculation with root-knot nematode eggs. Tillman (9%) and SRVR (19%) had the highest perce...
