pratylenchus thornei

Catalogue: GRDC Publications
Over the three survey years this allowed 307 comparisons ofFusarium DNA levels assessed at sowing using PreDicta B with the actual incidence of infection that developed by harvest as determined from laboratory plating (Table 1)... The predicted risk of crown rot development at sowing using PreDicta B was within one category of the actual level of infection measured after harvest in 121 paddocks (39%, light grey shading)... Some newer wheat varieties have a measurable improvement in their tolerance to crown rot but these current levels are not a complete solution to crown rot...

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...

Know your nematodes and set up a crop defence system in 2014.. WA growers are encouraged to find out what species and levels of root lesion nematodes (RLN) are present in their soils during the growing season... DAFWA research has indicated crops that are resistant to P. penetrans are often highly susceptible to P. neglectus or P. teres, highlighting the importance of knowing which species of RLN is present - as management of one RLN species may be causing an increase in another...

For Pratylenchus thornei , a moderately tolerant wheat variety (such as EGA Gregory) could return another 1.9t/ha compared to an intolerant wheat variety such as Petrie (or extra $450/ha with wheat valued at $239/t)... This year we'll present new information on the role of winter crops grown in rotation with wheat and details about the potential role of more resistant wheat in management of root-lesion nematodes... Our research has shown that nematicides will only reduce populations in the top soil layers...

Author/s: Soil Microbiology Section Published: 2010.. Root-lesion nematodes can take half your yield... Break up the soil by hand in a bucket so that all pieces are less than 1 cm in size keeping the six lots separate (Failing to do so may incur a processing fee of $78.41)...

On-going vigilance by testing soil for nematodes is essential when susceptible crops are planted... Populations of P. thornei after growing sorghum, sunflower and maize were similar to bare fallow (range of 2,900-4,500/kg soil at 0-15 cm (Figure 2)... Populations of P. thornei increased after growing soybean or mungbean compared to sunflower, sorghum, maize or clean fallow (Figure 2)...

On-going vigilance by testing soil for nematodes is essential when susceptible crops are planted... Populations of P. thornei increased after growing mungbean or soybean compared to sunflower, sorghum, maize or clean fallow (Figure 2)... Overall, populations increased five times compared to before planting the summer crops, but remained below 250/kg soil (Figure 4)...
