Mr Perrett said the Department of Agriculture and Food (DAFWA) would conduct the research into some of the key priority areas facing WA grain growers including break crops, plant disease, soil acidity, pests and spray drift.
Methods such as no-spray zones, to control spray drift into fields and surface waters, have been introduced in the United Kingdom and other European countries.
This information will allow farmers to avoid spraying pesticides when weather conditions indicate spray drift is likely.
And, when spraying, wear a protective mask and watch out for spray drift on breezy days.
Additional tests in an apple orchard demonstrated that the new sprayer reduced spray loss beyond tree canopies between 40 and 87 percent, airborne spray drift by up to 87 percent, and spray loss on the ground between 68 and 93 percent.
It addresses types of pesticides and crops; approval of pesticides; their application; operator exposure; spray drift, bystander, resident, and worker exposure; environmental aspects of spray drift; residues in food; and the future of pesticides.
Spray drift review: The extent to wich a formulation can contribute to spray drift reduction.
Reduction of spray drift by using air-induction nozzles, improved control of boom height, and an improved understanding of the mechanisms that lead to spray drift as explored in computer simulation models.
The assessment of spray drift is necessary to reduce the pollution of ecosystem, but it is particularly complex and very difficult to repeat spray drift measurements in the field with a high degree of reliability because weather conditions cannot be controlled [8-9], which was the major reason to develop wind tunnel protocols for the measurement of spray drift in controlled conditions.
Over the longer term, there's likely to be common ground between the wine and cannabis industries--shared land, shared concern for spray drift, shared need for agricultural labor, a shared place at the value-added agricultural table.
