2022 fungicide guides for pulse crops

After several good seasons in 2020 and 2021 that produced record yields in many areas of Australia, rainfall has been variable over summer in many regions. NSW and Queensland have had good rainfall over summer that has given full soil moisture profiles (some paddocks waterlogged). South Australia started with dry conditions for sowing winter crops but have recently received adequate rain to get crops germinated. Victoria had early plant establishment with warm soils and good soil- moisture in most areas, resulting in a higher disease risk. In Western Australia conditions have been very favourable for sowing crops and regular rain events have followed. This season will be favourable for many diseases as we head into spring. Many of these diseases need only limited moisture to infect crops (heavy dew or fog provides enough moisture), so monitoring needs to be continued throughout the season. Later in the season after canopy closure, higher water rates will aid in canopy penetration. Timely fungicide applications ahead of rain events will give the crop the best chance of a high yield. Susceptible crops need continuing fungicide protection for good pod fill so timely application of fungicides by ground sprayers will give the spray coverage required. Growers are recommended to rotate and mix fungicides from different group to minimise the risk of fungicide resistance developing in the pathogen populations.

Pulse Australia acknowledges the input of the state government pathologists in the preparation of this seasonal guide : Kurt Lindbeck (NSW DPI), Sara Blake (SARDI), Josh Fanning (Vic DPI), Geoff Thomas (WA DPIRD).

Australian Fungicide Resistance Extension Network (AFREN is a major GRDC investment) has additional materials available regarding fungicide use in crops.
