As farmers prepare to tackle summer weeds, NSW Farmers' Agricultural Science Committee chair Alan Brown said they should be mindful of several key precautions.

“Simple steps such as using the appropriate spray nozzle and spraying as close to the target as possible go a long way when it comes to preventing drift,” Mr Brown said.

“Monitoring weather conditions regularly while spraying is also crucial, and while we all want to get the job done, it’s vital that you stop spraying as soon as conditions become unfavourable for the job.

“Understanding the impact of new adjuvants and formulations of popular chemicals when selecting your spray mix is also essential to reducing spray drift, and consulting your agronomist will help ensure you have the latest information you need to spray this season.”

Off-target spray drift can occur when agricultural chemicals or vapour become airborne and drift outside the intended area when sprayed. This can happen if chemicals are applied at the wrong time of day, or during the wrong weather conditions.

As growers look to control weed pressure this summer, Mr Brown said continued vigilance was key to prevent damage to crops when spraying.

“Previous seasons saw significant damage as a result of off-target spray drift incidents, so it’s vital that we stay alert and take the relevant precautions to prevent further instances,” he said.

“Failure to do so can have extensive repercussions, on not just production and profitability but livelihoods, relationships and communities for years to come.”
