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

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.

Spring Pink Meeting Videos held on May 11:  Recording on YouTube is separated into 6 individual videos based on the topics below.  See related slides in pdf file below.

NY Herbicide Resistance Survey

With the recent documentation of evolved herbicide resistance in New York, including Palmer amaranth (glyphosate, ALS-inhibitors), waterhemp (glyphosate, ALS-inhibitors), horseweed (glyphosate, ALS-inhibitors, paraquat), lambsquarters (bentazon), Cornell wants to better understand the current "state of the state" with respect to herbicide performance and failure. Specifically, we are surveying growers/land managers/crop consultants/extension specialists/industry personnel, across cropped (e.g. agronomic, vegetable, fruit), ornamental/horticultural (e.g. Christmas tree farms, golf courses), and non-cropped (e.g. industrial, roadsides) systems in NY to describe the distribution of herbicide resistance in the state. This survey is VERY SHORT and should be QUICK to answer. It is also COMPLETELY ANONYMOUS. Your responses will help Cornell weed scientists plan future research and extension projects. Please access the survey using the link below:

New Weed Management Technology Survey

Want to move away from herbicide reliance? Are you using novel technologies to manage weeds? We want to know about it to inform our weed science research. A team of weed scientists from University of California Davis, Oregon State University, and Cornell University are asking berry, tree fruit, tree nut, and vine crop growers to take 5 to 10 minutes and answer this short and anonymous survey.
