摘要
Incorporation of nematocide granules by L-bladed rotavator gave more reliable [potato] yield increases and better control of cyst-nematode increase than incorporation by Roterra (rotary harrow), and measurements of granule distribution suggested that this could be attributed to the deeper distributions of granules achieved by rotavation. Pot tests showed that the variability of the granule distribution in the field is unlikely to limit the efficacy of oxamyl, but may limit the efficacy of fenamiphos, and these differences can be attributed to the greater mobility of oxamyl in soil.
