Damage and Reproductive Potentials of Pratylenchus brachyurus and P. penetrans on soybean.
Damage and reproductive potentials of Pratylenchus brachyurus and P. penetrans on soybean, Glycine max, cvs. Essex, Forrest, and Lee 68, were determined in microplot tests. Cultivar Essex was generally tolerant to P. brachyurus. Yield of Forrest was suppressed linearly with increasing P(i)'s in the sandy soil (r = -0.92) and loamy sand soil (r = -0.99). Low to moderate P(i)'s in the sandy clay ...
متن کاملControl of Pratylenchus brachyurus with Selected Nonfumigant Nematicides on a Tolerant and a Sensitive Soybean Cultivar.
A field study was conducted to evaluate soybean cultivar sensitivity to Pratylenchus brachyurus and selected nonfumigant nematicides for control of this nematode. 'Essex', a tolerant cultivar, yielded more than 'Forrest' , a sensitive cultivar, in an infested field. Plots treated with aldicarb, carbofuran, and fenamiphos had fewer nematodes 40 days after planting than nontreated plots. Plots pl...
متن کاملMethyl 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...
متن کاملHost 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...
متن کاملComparison 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...
