The Department of Primary Industries and Regional Development’s (DPIRD) Season 2022 webpages have been updated with all the latest information and advice to help farmers navigate the problematic end to the growing season.

Sprouting, staining and crop diseases, as well as flystrike are all presenting as end of year challenges for farmers because of protracted late season rainfall.

Regional intelligence and adoption manager Brendan Nicholas said that while the State was on track for another record harvest, grain quality would be impacted by rain in some areas.

“With harvest well underway, there have been widespread reports of pre-harvest sprouting and staining, hay damage and summer weeds in recent weeks,” he said.

“The Season 2022 webpages have a detailed article on the Falling Number Index for measuring sprouting, including susceptibility and managing the risk.

“While there is little that can be done now about staining and sprouting, the 2023 WA Crop Sowing Guide has Falling Number Index ratings to be considered alongside other factors when selecting suitable varieties and strategies to reduce the risk.”

The protracted rainfall has stimulated weed germination and crop regrowth, elevating the risk of disease carryover into the 2023 season.

“This vegetation can serve as a ‘green bridge’ for diseases and pests, with powdery mildew and leaf rust in wheat of particular concern for carryover into 2023 after being found in WA crops in 2022,” Mr Nicholas said.

“The Season 2022 webpages have a link to the recent PestFacts article on green bridge management strategies over summer, as well as advice for managing sclerotinia in lupin and canola crops.”

Summer weeds could also be a challenge for growers, which remove soil moisture and soil nutrients and can reduce crop emergence.

The Season 2022 webpages harness summer weeds information on control options, including chemical treatment, grazing and mechanical removal.

The wet conditions have also created conditions conducive to flystrike, particularly in southern districts.

The Managing flystrike in sheep article has advice on prevention, as well as treatment options.

The department’s free Flystrike Assist app is a valuable tool to help producers manage strict chemical withholding periods for both treatment and prevention.

The FlyBoss website also has several tools to assist wool producers to treat individual sheep or the whole flock, identify products and estimate wool residues, as well as decision support tools and management plans.

It is also important for producers to treat sheep showing signs of flystrike promptly and not transport them to saleyards while infested.

The rainfall has also seen increased worm burdens in sheep from across the agricultural region, prompting the need to treat young sheep with an effective drench.

Further advice on sheep worms and links to the Worm Boss website are available on the department’s website.
