The disease is spread via rain splash and infection on the top three leaves is a driving factor for yield loss. Septoria tritici blotch (STB) was prevalent across the state in 2022, with higher-than-average spring rainfall causing substantial disease development in some areas. use of support tools such as the StripeRustWM App.proactive foliar fungicide applications.up front fungicide applications – in furrow, seed dressings, coated fertiliser.variety selection – avoid susceptible varieties.A successful stripe rust integrated disease management plan will include: Growers should be prepared for the rust epidemic to begin early in the season and have an integrated disease management plan ready to implement. Green bridge control will be essential in the lead up to sowing, as volunteers host the rust inoculum. The stripe rust disease risk is expected to be high in 2023 with high inoculum loads across the state from the 2022 season. Paddocks that avoided susceptible varieties, had fungicides applied at seeding, and had timely foliar fungicide applications achieved the greatest stripe rust control. Wet cool conditions for the remainder of the season maintained a high level of disease pressure from stripe rust in susceptible varieties. Stripe rust epidemics began early in these growing regions in 2022 and South Australia followed suit with the first stripe rust report in late July. Summer rainfall through 20 caused flooding in QLD and NSW, driving a green bridge between the growing seasons and allowing stripe rust inoculum to proliferate. Stripe rust caused substantial damage and yield loss to wheat crops in the eastern states in 2022. Australian rainfall deciles for 2022 showing above average rainfall in South Australia, Commonwealth of Australia 2022, Bureau of Meteorology. Integrated disease management strategies were particularly important in this season with variety selection, proactive fungicide management and non-chemical farm management (for example, green bridge control, crop rotation and stubble management) providing the best opportunity for effective disease control.įigure 1. Many paddocks experienced yield losses, reduction in grain quality and/or grain defects from disease pressure. These conditions were very conducive for foliar disease development and wheat crops particularly suffered from powdery mildew, stripe rust and septoria tritici blotch. Wet conditions continued late into spring and early summer affecting conditions during grain fill and harvest. The 2022 growing season in South Australia received above average rainfall in most areas of the state (Figure 1). Inoculum levels will be high going into 2023: green bridge control, variety selection and fungicide strategies should be prioritised.Septoria tritici blotch, usually damaging in the HRZ, caused yield losses of 20% in the LRZ.2022 season resulted in high stripe rust disease.Above average rainfall in 2022 favoured disease development. Research, Development and Extension Data.Rust has also added fishing, underground rail network side tunnels, ice lake improvements and new Underwater Ambience & Effects.Business development and commercialisation “If you like to take risks, the occasional mess hall room will allow you to play some high stakes poker, listen to music with your group and cook some meats before heading back to pick a fight with the NPCs that are dwelling in the corridors.” You will also find microphones in some rooms that let you broadcast your commands into the entire base’s network. The new and improved player map will also let you see the layout of the base for each floor. “The bases have a wide network of CCTV cameras you can connect to to plan your exploration ahead of time. From there, make sure you have come prepared to face the various puzzles on offer. "You enter them from a ‘moonpool’ in which you re-surface with your submarine. They will come in a variety of shapes and sizes, and for now, with two entry points. “The new underwater labs are fully procedural dungeons that reside on the ocean floor.
