N. A. Minton, H. B. Gillenwater

Abstract


Five dosages of methyl bromide were used to fumigate peanut (Arachis hypogaea L.) shells and whole pods of peanuts in l-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. Steeh. 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 seed germination occurred at the 50.9-mg/liter dosage. Key Words: Lesion nematodes, Arachis hypogaea L,
