Reproductive and Damage Potential of Ditylenchus destructor on Six Peanut Cultivars
Abstract
Commercial peanut cultivars were evaluated for host suitability and sensitivity to Ditylenchus destructor. All cultivars were susceptible. Approximately 94% of the final population were in the pods. Highest Pf occurred at harvest on early maturing cultivars. Damage occurred on four of six cuttivars at Pi = 100/3 liters of soil and all six cultivars at Pi = 1,000. Norden and Selmani were the most susceptible cultivars. Sellie was the most tolerant and highest yielding cultivar. This cultivar may be the most profitable one for growers. Key words: Arachis hypogaea, Ditylenchus destructor, economic loss, nematode, pathogenicity, peanut.Downloads
