Nematodes associated with wheat in Queensland
1965
Colbran, R.C. | McCulloch, J.S.
A preliminary survey of nematodes in Queensland wheat fields was carried out in the spring of 1964. Soil samples were taken from four areas regarded as below average in growth on each of 53 farms in the Biloela, Dalby, Goondiwindi, Kingaroy, Theodore and Toowoomba districts. The numbers of farms in each district were 3, 8, 11, 12, 11 and 8 respectively. A sample consisted of approximately 2 lb of soil around the roots of five randomly selected plants. Data on infestations exceeding 50 per lb for the ectoparasitic stunt nematode Tylenchorhynchus brevidens Allen and the endoparasitic root-lesion nematodes Pratylenchus neglectus (Rensch) (syn. P. minyus Sher and Allen), P. thornei Sher and Allen and P. zeae Graham, which are recognized parasites of wheat, are presented in Tables 1-4.
