Recent research has identified that northern grain-growing soils are capable of suppressing root-lesion nematodes, especially in the top layer (0-15 cm) of soil, and this capacity can be enhanced by increasing the biological activity of that soil, mainly through carbon inputs and minimising soil disturbance... Results from 600 samples tested in 2010-13 showed that 50% of paddocks had populations above 2 nemotodes/g soil... A recent survey in Central Queensland found that 28% of paddocks had RLN, with 26% of those paddocks containing P. thornei...

There are two important species of root-lesion nematode in the northern grain region, Pratylenchus thornei (the most commonly found species) and Pratylenchus neglectus ... Root-lesion nematodes feed and reproduce inside plant roots (endoparasitic nematodes)... Root-lesion nematodes in the northern grain region can be found deep in the soil profile and in some cases peak populations occur 30-60 cm deep in the soil...

" Nematode Resistance relates to the effect of the variety on the nematode density present within the paddock... There will be a reduction in nematode densities when these varieties are grown... Growing the varieties will, to a lesser degree than growing a resistant variety, reduce the density of the nematode in question and reduce yield loss in subsequent intolerant crops...

The key to management of root lesion nematodes relies on three important points: 1... Growing tolerant and resistant crops to keep root lesion nematode populations at low, manageable levels... Figure 2: We followed populations of P. thornei in the soil profile during a 4 year crop rotation trial at Formartin (70km W of Toowoomba)...

Summary Root-lesion nematodes are found throughout the northern grain region and have the potential to reduce wheat yields by up to 50% and chickpea yields by 30%... Best management practices rely on choosing tolerant varieties (that will yield well when nematodes are present) and growing resistant crops (to keep nematode populations low)... The most reliable way to tell if nematodes are present on farms is to have soil tested in a laboratory because symptoms of nematode damage can be difficult to distinguish - often attributed to "a dry finish", "a poor season" or "nutrient deficiencies"...

" Crop sequences to manage soil pathogens and reduce the yield gap of northern grain production... The aim is to answer the question: By how much will my current cropping sequence promote or decrease nematode populations The process of understanding the sympathetic and antagonistic interactions of crops and nematodes in the northern grain region will also provide information to answer the broader question... It is intended that this approach combining the use of modelling and the efficiency frontier will help evaluate and inform individual farmer decisions and enable testing of decisions beyond the seasons experienced during the project...
