Nick Poole from the Foundation for Arable Research says new tools to fight leaf diseases and respond to crops' nitrogen needs could be worth hundreds of dollars a hectare to high-rainfall zone growers... PHOTO: Kellie Penfold New tools to fight leaf diseases and respond to crops' nitrogen needs have been developed for cereal growers in the high-rainfall zone (HRZ), following a three-year project by the Foundation for Arable Research... "For example, our previous research gave confidence to cereal growers to delay nitrogen and fungicide decisions until stem elongation," Mr Poole says...

Until, a few years down the track, herbicide resistance emerges as a result of using below recommended label rates... AHRI postdoctoral fellow Dr Roberto Busi warns that Sakura (Group K) is a great pre-emergence herbicide to control ryegrass, but using below-label rates poses a risk of rapid evolution of ryegrass resistance and should be avoided... To develop a cost efficient herbicide budget, AHRI suggests growers consider using the more expensive herbicides at full rates over smaller areas and concentrating on doing a good job - rather than cutting rates over bigger areas...

Inter-row weed control in wide row lupin using knockdown-based tank mixes Dr Abul Hashem 1, Ray Fulwood 2and Chris Roberts 3, 1Senior Research Officer, Department of Agriculture and Food, Northam, 2Farmer, Meckering, WA, 3Technical Officer, Department of Agriculture and Food, Northam.. Weed dry matter was reduced (Figure 2) but due to the dry season, only marginal increases in lupin yields compared to the broadcast treatments were realised due to the likely competition for water... Enhancing the depletion of the existing seedbank is just as important as controlling seasonal seed set...
