Abstract
Anthurium (Anthurium andraeanum) 'root rot and decline' and Radopholus similis, the primary cause of that disorder, are most effectively suppressed by phenamiphos, but traditional nematicides are becoming unavailable to growers for various reasons. Since Dettol, Jeyes Fluid, and bleach are proving very efficacious to disinfest soil and some plant materials of noxious nematodes, these household disinfectants were compared with phenamiphos and cadusafos for control or R. similis in a cv. Kaumana anthurium planting. The treatments were first applied to 12-week old plants, then every five months. Leaf number, leaf width, petiole length and R. similis root populations were measured initially, then at five, 10, 14 and 18 months, and blooms produced over a four-week period starting month 15 were counted, as were suckers per plant and plants per plot at 18 months. After 18 months, petioles of the water-, Dettol-, Jeyes Fluid-, and bleach-treated plants were shorter, and leaves no wider than at the outset, and these plants put on no more that 50% more leaves, while the phenamiphos- and cadusafos-treated plants almost doubled and tripled leaf number respectively. Petioles of phenamiphos-treated plants were marginally shorter than at the outset, but laminae were somewhat wider, while petioles of the cadusafos-treated plant were approximately 20% longer, and laminae 33% or so wider. The cadusafos treatment suppressed R. similis effectively and, at 18 months, saw to the highest levels of sucker and bloom production. There was evidence of injury to plants treated with the household disinfectants.....
