Plant-parasitic nematode management in pineapple

Management of nematodes in pineapple is evolving. For decades after the discovery of 1,3-D in the 1940s, multiple nematicides were used but by the 21^st century only a few products continued to be available for nematode management. In a series of experiments, spirotetramant, abamectin and fluopyram were evaluated for nematode control in pineapple. Spirotetramat was effective in greenhouse tests with a crown dip followed by a 1-month postplant application more effective than a single crown dip. In the field, spirotetramat efficacy was less clear compared to a fenamiphos treatment. Abamectin reduced nematode populations.
