Spraying resource for growers

Date: 21 Mar 2012


Grain growers in the southern cropping region are being provided with a new resource to help them plan and effectively execute pesticide spray applications to avoid spray drift.

The Grains Research and Development Corporation (GRDC) has just published Weather Essentials for Pesticide Application which aims to help those applying pesticides to understand, observe and interpret local weather elements to ensure the safe and efficient control of pests and diseases in agricultural crops.

Author and meteorologist Graeme Tepper, of MicroMeteorological Research and Educational Services (MRES), says unsuitable weather conditions can further shorten the opportunity for growers to safely spray.

“It is therefore essential that spray applicators are able to identify and react to weather conditions at a local scale,” Mr Tepper says. “The weather factors that are important to the application of pesticides can be significantly and critically different to conditions indicated by weather forecasts, weather maps and off-site weather observations – especially overnight and into mid-morning.”

Mr Tepper says it is essential that all spray applicators understand microclimates that impact on the effectiveness of spray applications and spray drift. Growers need to be vigilant and be prepared to change application techniques or halt operations in order to minimise the risk of spray drift and maximise the potential for the pesticide to reach the appropriate target.
