3) It is widely accepted that fungicide applications are generally most effective when applied with small-droplet technology, but such applications are also associated with the highest risk of spray drift... The project is about optimizing pesticide spray applications by: identifying spray technologies and spray settings with low risk of spray drift, applying pesticides in accordance with latest knowledge about pest behaviour in response to pesticides and minimizes the risk of target pests developing resistance, and by using pesticides with documented efficacy against target pests... A key nozzle technology on which we will focus is air-inducted nozzles and we will screen several popular ones first in the wind tunnel to select those that produce good control of droplet size with at least 20% air inclusions by volume...

Avoid spray drift by recognising unsafe conditions.. Spray consultant Bill Gordon, whose work is supported by the Grains Research and Development Corporation (GRDC), says surface temperature inversions commonly develop overnight, when the ground loses heat and the low-level air cools. ".. Meteorologist Graeme Tepper, of MicroMeteorology Research and Educational Services, said when surface inversions exist pesticides in the air can move long distances at high concentrations near the surface and adversely impact non-target receptors, often in directions and locations that could not be estimated from general weather patterns.

Herbicide and pesticide applications to grain and other crops in Australia are likely to be the subject of increasing restrictions from mid 2010 onwards as the Australian Pesticide and Veterinary Medicines Authority (APVMA) imposes no spray buffer zones and other spray drift mitigation measures to prevent off-target pesticide movements onto sensitive areas... For ground-based applications, these models offer few choices of application..... Data to support appropriate spray regulations..

The Services are to increase awareness by growers, advisers, machinery dealers and trainers (primary information providers) in the Northern and Southern grain growing regions of the factors that contribute to spray drift and the tools and techniques available to minimise the potential for spray drift to occur without significantly impacting on product efficacy by: 1) Developing and updating resources and training materials for spray drift management courses and to the GRDC to include the most current information available for spray..... Spray operators can obtain advice on minimising the risk of spray drift by consulting the Grains Research and Development Corporation (GRDC) Fact Sheet Practical tips to reduce spray drift... Resource can help growers plan for summer spraying..

The capacity of the plant to take up potassium is not directly related to potassium in solution... Spraying is best done when there is some wind, and when the operator can be sure that wind direction has stabilised... Driftability of amine formulations The 2,4- D products Surpass and Amicide 625 which were used in the trial are considered to be nonvolatile any drift that is associated with these products will be droplet drift not vapour drift...
