Average coverage in most spray applications is far more than needed to control/kill the pest. Usually as little as 10-20% coverage is adequate. Does killing dead bugs more dead with higher average coverage really indicate you made a better spray? Our philosophy when designing to canopy deposition studies is to help you find and understand the least-covered, and therefore most vulnerable, areas in your post-emerge or horticultural sprays. Focus on least-coverage, rather than average coverages, provides powerful insight and better correlations to spray efficacy. Specialists in low and ultra-low volume spray evaluations, and fine-droplet spraying. (of course we do all the other stuff too). Qualitative and quantitative methods to suit your needs.
