Keep the Spray on the Weeds!
AGnVET is committed to ensuring the safety and well being of its farming communities. With summer spraying requirements not too far away it is essential everyone is aware of their legal requirements and obligations when it comes to safe spraying practices.
Off-target spray drift is a significant issue for summer cropping in Australia, causing injury and economic damage to a range of crops and the environment.
It is important that chemical users “keep the spray on the weeds” not only from an efficacy standpoint but also to prevent off-target injury to crops.
Spraying agricultural chemicals, whether from the ground or the air, needs to be properly planned and carefully monitored and executed, to maximise effectiveness and to minimise the risk of off-target chemical movement.
The environmental conditions in summer are conducive to inversion conditions which can lead to large plumes of chemicals moving considerable distances off-target. Many of the causes of off-target spray drift are a result of:
- Poor equipment set up
- Product selection of high volatility products
- Application in environmental conditions which are not suitable
