Host Specificity of Four Populations of Pratylenchus brachyurus.

Four populations of the lesion nematode Pratylenchus brachyurus were tested in a greenhouse on seven selected plant species to determine host suitability and usefulness in identifying physiological races of the nematode. The differential plants were 'Florida 77' alfalfa, 'Harvester' snap bean, 'Rough Lemon' citrus, 'Pioneer 304C' corn, 'Florunner' peanut, 'Braxton' soybean, and 'Rutgers' tomato...

Methyl Bromide Fumigation of Pratylenchus brachyurus in Peanut Shells.

Five dosages of methyl bromide were used to fumigate peanut (Arachis hypogaea L.) shells and whole pods of peanuts in 1-liter flasks for 24 hr at 25 C. Methyl bromide dosages as low as 24.5 mg/liter killed all Pratylenchus brachyurus (Godfrey) Filip. &Sch. Stech. in peanut shells. Dosages of 44.6 and 50.9 mg/liter killed all but one or two nematodes in shells of whole pods. A 15% reduction in s...

Comparison of Populations of Pratylenchus brachyurus Based on Isozyme Phenotypes.

Enzymes from females of five Pratylenchus brachyurus populations and one P. scribneri population were analyzed by isoelectric focusing electrophoresis. Of the 18 enzyme systems investigated, only malate dehydrogenase (MDH), phosphoglucomutase (PGM), and phosphoglucose isomerase (PGI) were detected from all five P. brachyurus populations and P. scribneri. Faint bands were detected for isocitrate...
