7 Breakout groups Entomology, Plant Pathology, Weed Science Should we continue funding the same projects in 2016 that were funded in 2015? Within the list of priorities has any become a more serious problem that needs more attention? Are there certain priorities that are of national importance versus regional interest? Are there any new products that really have a lot of potential to the degree that a particular priority should be ranked higher than others? Where do resistance problems exist that need alternatives or how to integrate biopesticides, conventional products and cultural practices to manage the pest? In conclusion, within the groups of Fruit, Organic, Other and Vegetable what are the most important priorities?( Note you can all vote how you choose, this is to facilitate exposure to different opinions and stimulate thought)
