Spring Meeting Resources

Resources from the 2020 spring meetings in pdf, recorded webinar, and video format will be linked here as they become available. 

For Upcoming Meeting in this series please check https://lof.cce.cornell.edu/event.php?id=1429

Pruning Honeycrisp for Annual Production Video  - Precision pruning is a strategy to reduce the flower bud number per tree to a pre-defined flower bud number through pruning. This video explains how to manage Honeycrisp flower bud load with an optimum of 1.8 flower buds (left after pruning) relative to final fruit number. Honeycrisp growers should use flower bud counts before and after pruning to precisely leave an optimum number of flower buds to guarantee annual production (and reduce biennial bearing) every year. The video also shows how to dissect and identify a Honeycrisp floral bud from a vegetative bud.  This video focuses on Honeycrisp, however it contains basic pruning techniques that can be applied to all tall spindle orchards.

NYCAMH Fit Testing Requirements

Considering NYCAMH for your respirator fit testing?

Here are some key facts and helpful tips about medical clearance:

Medical Clearance ? Fit Testing (They are not the same!)

Before you can wear a respirator or be fit tested, OSHA requires a medical evaluation under the Respiratory Protection Standard (29 CFR 1910.134). This evaluation must be conducted by a licensed healthcare provider to determine if you are physically able to use a respirator safely.
