Crop rotations must be selected according to the species of root-lesion nematode present on your farm... Summer crops offer a means of reducing the populations of root-lesion nematodes but only when you know which species of root-lesion nematode is present... Results from a field experiment show that populations at 0-15 cm increased after harvest compared to the populations at planting (striped bar)...

The results of experiments conducted in our PA research program suggest that variations in the soil often explain much of the variation in crop performance... Using Figure 4a as an example, spatial interpolation is used to estimate the yield that would have been achieved from treatment 2 in the strips that actually contained treatment 1, and vice_versa... Interpolation: A term describing a number of mathematical procedures which are used to create continuous map surfaces from values measured at points...

In many cropping soils of south-eastern Australia the presence of nematodes limits field crop production... Recent reports by Murray and Brennan (2009 a & b) estimated that in south-eastern Australia alone, nematodes are currently reducing wheat and barley production by 4.9% ($98 million) and 5.1% ($42 million) respectively, with losses in excess of 20% possible in the absence of appropriate control strategies... Growers can minimise yield loss caused by the nematodes in two ways...

The main objective of this project was to develop improved prediction and better management options for controlling Rhizoctonia disease through identification of critical regulating factors influencing R. solani , microbial activity and host plants... It should be noted that multiple summer rainfall events reduce the Rhizoctonia pathogen inoculum levels from high to lower disease risk, whereas prolonged dry periods can even cause an increase in inoculum levels... Results from multiple sites in SA and NSW indicated that inoculum levels were generally reduced after non-cereal rotation crops including peas, medic pasture and fallowing compared to cereal crops...
