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..

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..... New label instructions and regulations will be the outcome of a current review by the Australian Pesticides and Veterinary Medicines Authority (APVMA) of pesticide applications and spray drift management...

Efficient Spraying to Meet Environmental Demands "learning to spray with coarser sprays" Spraying is about placing the correct dose of chemical at the right place at the right time... Without pesticides the world would find feeding itself a monumental challenge, but this does not mean that the community at large embraces the idea of managing pests with chemicals... As farmers today, I believe we are making some decisions that may lead to increased drift risk...

" Core DRT Database to Support the Ground Application of Pesticides (boom sprayer), accommodating Nozzles, Formulations and Adjuvants.. The Australian Pesticides and Veterinary Medicines Authority (APVMA) recently implemented new policy requiring new pesticides to be assessed for the potential risk of spray drift, but has indicated that it will consider submission of further data by stakeholders to develop a drift reduction factor model, incorporating the use of new technology low drift spray nozzles, shrouds and spray additives... With pesticides accounting for up to 30 per cent of the variable input costs of grain production, ensuring spray operations are effective and that drift is minimised will save money and time...
