C.  aNematode control in pineapples.  c1960  aA problem facing pineapple growers in Queensland is that of declining yields, and fewer ratons on re-plant land. Recent investigations have shown that these conditions are frequently attributable to the nematode complex associated with the roots. The important members of this complex are root-knot nematode which produces root swellings, a root-lesion nematode which feeds within the root cortex, causing premature breakdown of the fibrous roots, and a spiral nematode which feeds externally, producing superficial lesions. the result of nematode infestation is a root system reduced in size and efficiency, a smaller plant and smaller fruit.  aAbacaxi-doencas por nematoides-controle  tQueensland Agricultural Journalgv.86, p.386-388, 1960.
