3. Choose tolerant wheat varieties to maximise yields (go to nvtonline.com.au).. From our research, the optimal temperature for reproduction of Pratylenchus thornei is 22C; populations increased, although at slower rates, from 17 to 28C... We have also found reduced growth and yield of wheat and chickpea following canola in a low phosphorus soil (7 mg/kg Colwell P) in two separate 2-year winter crop rotation experiments...
