Further development of Pesticide dose Adjustment to the Crop Environment (PACE) for fruit spraying with broadcast sprayers. - PS2002

The proposed research will launch a newly developed PACE system for use in commercial UK apple orchards for further practical evaluation and extend underpinning R & D to a wider range of top fruit crop structures. PACE systems provide user information for the adjustment of pesticide label dose to suit a defined range of crop structures so that the mean and variability of deposition is minimised without significantly compromising biological efficacy. This information will help growers identify practical opportunities to reduce pesticide inputs to fruit production and provide support for drift mitigation purposes (e.g. Reduced dose applications under Local Environmental Risk Assessment for Pesticides for broadcast air-assisted sprayers). The information generated by this research is vital to the future needs of the industry to help them implement DEFRA policy aimed at providing effective methods of pest and disease control that are consistent with protecting the safety of people, animals and the environment. The research has the potential to identify further opportunities to reduce pesticide use and improve the European Community regulatory framework (Directive 91/414/EEC).
1. Launch the PACE system for UK apple orchards and monitor progress.
2. Develop PACE systems further with special attention to: simplifying user calculation, compatibility with agrochemical industry approach based on tree row volume scaling, increasing the range of data available for different top fruit structures, minimising losses beyond the primary target and improving accuracy of LIDAR measurements of crops with high area density.
3. Determine the spray volume deposition characteristics of a wide range of top fruit trees including an assessment of spray losses.
4. Promote European wide aspects of PACE.
