Reminder on spray drift
AS planting and spraying operations increase across Queensland this summer, all chemical users are being reminded of their responsibility to minimise spray drift and protect surrounding areas.
Key tips for responsible spraying include checking weather conditions, using appropriate equipment, keeping detailed spray application records and communicating with neighbours about nearby crops that may be at risk.
Department of Primary Industries (DPI) and Cotton Australia are partnering to promote best practices, including reading chemical labels carefully to ensure products reach their intended targets.
They also encourage sprayers to connect with neighbours to identify susceptible crops and coordinate activities.
Michael Reid, general manager of Plant Biosecurity and Product Integrity at DPI, emphasised the importance of timing and monitoring conditions.
“The best time to spray is during light, steady breezes and moderate temperatures,” he said.
“Avoid spraying on windy days or during thermal inversions. If conditions aren’t suitable, postponing is often the safest choice.”
Cotton Australia general manager Michael Murray highlighted the importance of monitoring inversion conditions.
“Inversion conditions, which increase spray drift risks, are common during summer evenings and nights,” he said.
Factors such as weather, droplet size, boom height, travel speed, and application method all influence the likelihood of spray drift.
To comply with the Chemical Usage (Agricultural & Veterinary) Control Regulation 1988, users must also measure and record weather conditions at the application site.
