Growth of Potato and Control of Pratylenchus penetrans with Oxamyl-treated Seed Pieces in Greenhouse Studies.

摘要: Oxamyl was applied to both uncut and cut potato tubers in aqueous solutions of 1,000 32,000 [mu]g/ml. Emergence greenhouse pots delayed for a day or more after soaking tuber pieces After 10 weeks plant growth greater, relative the control, when Pratylenchuspenetrans-infested soil planted with soaked 20 minutes Soaking 40 did not increase nematode control nor affect growth. at [mu]g/ml reduced numbers P. penetrans by 20% roots 35%; [mu]g/ml, were 73-86% 86-97%. The plants developed from over period weeks, but lesion nematodes had begun soil. Key words: chemical root-lesion nematode, Solanum tuberosum, Vydate.
