Australian cereal growers adopting harvest weed seed control systems (HWSC) are driving down weed populations to lower levels on their farms, and extending the life of the herbicides they use... Dr Walsh said the problem of herbicide resistant weed populations globally was particularly severe in production systems where herbicide dependence resulted in a lack of weed control diversity... "Although herbicides remain the number one weed control tool in Australian cropping systems, it is now clear that the inclusion of HWSC systems in weed management programs is enabling weed populations to be driven to very low levels, providing some insurance for the sustainability of remaining herbicide resources," he said...

The results of the experiments have given Jeff the confidence to realise that he does have a viable, cost-effective alternative knockdown herbicide to glyphosate... Double knockdown (T 2.2b, page 128) Weather permitting, a double knockdown is implemented on resistant ryegrass paddocks prior to sowing using two non-selective herbicides (glyphosate followed by paraquat + diquat or paraquat, the choice being dependent upon the range of weeds present)... Helpful advice The Grays still enjoy the challenges and can see that they have made enough progress to feel they are being successful in managing a serious annual ryegrass problem...
