Apply Mating Disruption Dispensers Before First Moths Fly

Monday Feb 01, 2021

Mating disruption dispensers work by releasing synthetic pheromone which prevents or delays males from finding and mating with females. Therefore, dispensers need to be placed in your orchard before the first moths fly and mate. First moth flight (= biofix) occurs at around 175 DD. We recommend to place pheromone traps before first apple blossoms open or by 100 DD whichever comes first.

Planning for Fire Blight Prevention

Monday Apr 15, 2019

As Fire Blight season approaches make sure you have your fire blight plan in place. Most products work best when applied within the 12-24 hour window before a wetting event so a good plan is critical to timely execution. Know your high-risk areas, calibrate your sprayers, have products on hand, and be agile to change plans when mother nature and thinning change the reality for you. Check out our newly updated Fire Blight Page for ideas on improving your programs. Any time there are blooms on the tree there is risk of fire blight.

The New DAS

We gave the DAS website a major makeover that will launch in early March. This long-anticipated upgrade entailed an entire rebuild of DAS and was necessary to keep up with browser and mobile capabilities as well as to prepare DAS for modular growth. We kept all of DAS’s functionality while noticeably improving the mobile experience.
