Abstract
The era of nematode control with effective but toxic products like methyl bromide, EDB, DBCP, ethoprop, and fenamiphos has nearly come to an end in the USA and other parts of the world.
A search for environmentally friendly and effective alternatives for nematode control in pineapple has been underway.
In greenhouse tests, Messenger® (the harpin protein) was not effective in controlling nematode damage to pineapple.
Maxicrop® (the seaweed Ascophyllum nodosum), Mity-Gro® (the rhizobacterium Bacillus sp.), and Agri-50® (potassium phosphate) also did not reduce nematode damage to pineapple in greenhouse experiments.
Actigard®, an inducer of systemic acquired resistance, reduced nematode populations on pineapple by nearly 50% in greenhouse trials.
Dragonfire CPP®, a sesame oil product, increased pineapple growth in nematode infested soil.
Preplant applications of methyl iodide reduced nematode populations densities to numbers similar to treatments of 1,3-D in two field tests.
However, plant crop yields were not as high in the methyl iodide treated plots as compared to the 1,3-D treated plots.
DiTera® (heat-killed Myrothecium verrucaria) reduced nematode damage to pineapple plants, increased early root growth, and resulted in acceptable yields.
Many environmentally friendly products have not proven to be effective in controlling nematode damage to pineapple.
However, a few environmentally friendly products are promising in greenhouse tests and preliminary field trials.
Nematode control in pineapple is in transition and will continue to change as effective, safe and economical controls are evaluated in the field.
