A new wheat variety Scepter is being promoted as a step-change in yield and rust resistance in taking forward the advances delivered in the successful Mace variety that was released in 2009... The breeding company Australian Grain Technologies (AGT) - of which the GRDC is a shareholder - says Scepter takes these gains further... Tim Harvey, the Commonwealth Bank's general manager regional and agribusiness banking New South Wales, says the research findings show that younger growers are excited about the future: "Younger growers understand the importance of being proactive in building their business and their focus is very much on investing for the future," he says...

The yellow dwarf diseases of cereals have now been divided into two groups, barley yellow dwarf virus (BYDV) and cereal yellow dwarf virus (CYDV)... Where resistant varieties are not an option the management of aphid activity in crops especially early in the season to prevent its spread and or delayed sowing to avoid the main aphid flights in the autumn can reduce YDV infection... Later sowing to avoid the main aphid flights will reduce the incidence of YDV but this needs to be weighed up against possible yield reduction from delayed sowing...

Hart Winter Walk: virus explained to growers.. Ms Davidson explained that when growers first started reporting widespread damage in June it was initially put down to incorrect herbicide use, but as more crops started showing yellowing leaves a different picture emerged... Crops such as chickpeas, lentils and field peas had not emerged when the first round of the virus hit, but Ms Davidson told growers that pulses will also be susceptible to BWYV in spring...

While the recent cold weather has impacted aphid numbers and activity, the pressure earlier in the season means that there is a level of primary infection in some crops which could escalate rapidly if aphid numbers build significantly in spring... According to NSW Department of Primary Industries plant pathologist Joop van Leur, testing to identify the virus species present in faba bean is still in progress early indications are that the main virus present is Bean yellow mosaic virus (BYMV) with smaller incidences of Bean leafroll virus (BLRV) and other luteoviruses... Consultants and growers are being urged to monitor aphid populations closely in the lead up to spring and implement control strategies early to avoid severe virus infection later in the season...

Ms Davidson explained that when growers first started reporting widespread damage in June it was initially put down to incorrect herbicide use, but as more crops started showing yellowing leaves a different picture emerged... "If crops show patchy infection it may be necessary to control the aphids to prevent further spread of the virus into unaffected parts of crops during late winter and spring.".. Crops such as chickpeas, lentils and field peas had not emerged when the first round of the virus hit, but Ms Davidson told growers that pulses will also be susceptible to BWYV in spring...

A near-perfect start with good summer and autumn rain coupled with mild temperatures saw crops jump out of the ground... Insect pests including green peach aphid (GPA) and the resulting beet western yellows virus (BWYV or synonym, turnip yellows virus) and diamondback moth (DBM) both proved headaches for growers at different stages of the growing season... Mr Baker says the colonisation of DBM in canola crops this year looks to be at a lower level for much the same reason as the risk of GPA and BWYV is this year - a much drier summer and early autumn than last year and less of a green bridge on which to survive...

Canola attack spurs resistance campaign.. In Australia, the green peach aphid (GPA) primarily attacks canola by sucking sap from leaves and flower buds... For example, pirimicarb is not recommended for GPA control in canola crops in Western Australia, Queensland and South Australia due to the widespread levels of resistance to this chemical in these states...
