New research by the NSW Department of Primary Industries (DPI) will focus on the fungal disease Verticillium wilt to help the Australian cotton industry manage the risk associated with the disease.
An international team of researchers has uncovered an important link to a disease which, left unchecked, could prove devastating to wheat.
A three-year research initiative has analysed samples of yellow spot – arguably Australia’s most economically damaging wheat disease – generating valuable knowledge that will help breeders develop varieties with improved disease resistance.
Chickpea growers and agronomists are being advised to `watch and act accordingly’ when it comes to managing the fungal disease Ascochyta blight this season.
Farmers in Victoria are being warned that a trio of factors has increased the risk of cereal crops suffering from foliar disease this season.
The devastating chickpea disease, Ascochyta blight, has made an early appearance this season with agronomists detecting the first outbreaks of the disease in emerging crops in southern Queensland.
With the 2017 cropping season shaping as a high risk year for barley leaf rust and wheat leaf rust in Western Australia, it is not too late for growers to control regrowth from last season’s crops that can harbour rust pathogens.
A virulence change in the Ascochyta blight pathogen has broken down the resistance of chickpea varieties to the devastating disease, with all current varieties now rated as either susceptible to moderately susceptible to infection.
Growers across the southern cropping region are avoiding extensive yield and economic losses by knowing the risk of soil-borne diseases before they begin sowing this year’s crops.
Predicta B DNA-based soil tests across northern NSW and southern Queensland so far this year suggest the risk of crown rot and root lesion nematode (Pratylenchus thornei) for 2017 crops is similar to 2016, with 26pc and 49pc of paddocks recording medium to high risk levels respectively.
