Humidity is important in spraying. With the average tank of pesticide being 90 to 99.5% water, evaporation plays an important role in both droplet size and active ingredient concentration. Low humidity causes droplets to evaporate faster, potentially increasing drift and reducing uptake. But relative humidity (RH) isn’t the best way to measure this effect because […]

Horticultural crops cannot be produced commercially without the use of pesticides to manage the impacts of insects and pathogens. Growers recognize the importance of pollinators and in some cases, rely on bees for pollination. Growers are practicing due-diligence to try to minimize the effects of necessary pest management activities on bees. There’s a fine balance […]
We tend to overestimate the effect of a technology in the short run and underestimate the effect in the long run. –Amara’s Law of Computing We tend to overestimate the effect of a stewardship mistake in the short run and underestimate the effect in the long run. –Wolf’s Adaptation of Amara’s Law to Agricultural Stewardship […]
The following question arrived from one of our prairie clients last week: “A retailer is promoting the use of hollow cone nozzles to be used on field sprayers (20” spacing) to apply fungicides which he claims out-perform any regular and twin fan tips. Claims: create an extra fine droplet for maximum coverage on the canopy […]

“What is the right way to apply this pesticide?” It’s one of the classic questions. Applicators know that spray method determines the efficacy of the application as well as its environmental impact. And it has to use time and water resources efficiently to make sense. To answer the question properly, we need to take things […]
