Post-plant control of nematodes in bareroot nurseries

The effect of fenamiphos (Nemacur) on Pratylenchus penetrans under Douglas-fir seedlings was evaluated in a Washington State transplant nursery. Optimum nematode control was obtained using 6 lb ai/a. Nematodes in the roots were reduced by almost 88 percent, and in the soil by 90 percent fifteen weeks after treatment. Nemacur at 3 and 6 lb ai/a increased seedling height by 15 and 23 percent respectively, and root weight by 38 and 43 percent respectively over untreated seedlings. These treatments had little effect on mycorrhizae development.
