Tis the season of webinars! If you're looking for recordings of past tree fruit webinars Cornell ENYCHP has been involved in, they could be in one of a few locations….. we compiled them all into this post for you. Simply click on the webinar title to be taken directly to the recording.  We recommend bookmarking this page if you'd like to come back to them in the future, and we will continue to update this listing as new webinars occur.

Thorough incorporation of adequate amounts of lime prior to planting a new orchard is essential. The topsoil (0-8 inch depth) should be adjusted to pH 7 and subsoil (8-16 inch depth) to pH 6.5. An adequate liming program based on soil tests should be the first consideration in developing orchard fertilization   plans. Lime is the most economical source of calcium and magnesium. Regulation of soil pH through liming is also necessary to achieve optimal response to other nutrient elements. Fruit from Honeycrisp plantings can suffer from a physiological disorder called bitter pit (BP).  The mitigation of BP requires the implementation of multiple tactics, of which the maintenance of soil pH around 7.0 helps.

High tunnel systems vary a lot - from super simple to all the bells and whistles - depending on grower goals, crops, finances, etc. so it's hard to make one list of improvements that fits everyone's situation. Maybe you've done all these things, or maybe you don't need to. Hopefully there's something in the list below that's helpful to your high tunnel management in the coming year!    

There is a lot of speculation about a herbicide shortage for the 2022 growing season, which will impact weed management decisions starting with fall applications.  The two main active ingredients that we're hearing about right now are glyphosate (Roundup, others) and glufosinate (Liberty, others), both associated with an increase in cost.  There will likely be limited supplies of other pesticide active ingredients as well, but in the short term, a shortage of these two active ingredients poses some major challenges for corn and soybean production.  The purpose of this article is to discuss ways to minimize the impact of herbicide shortage on corn and soybean production in the Midwest.  As you search for alternatives to these two herbicides you may have already determined that weed control guides produced by University Extension and Industry will become your most important tool for planning your herbicide purchases for many years to come. 

Soil sampling is an important part of managing your crops, but it's important to do it correctly. In this video, ENYCHP vegetable specialist Amy Ivy demonstrates how to take a soil sample.

This is a recording of an hour long webinar held by Amy Ivy and Chuck Bornt of the Eastern NY Commercial Horticulture Program and Mike Davis of the Cornell University Willsboro Research Farm on Nov 8, 2018.

A copy of the PowerPoint is included in the 'read details' section below. With funding from the Northern NY Agricultural Development Program.

Fall is the best time to test your soils so that any amendments you add, especially if you need to change your pH, have time to take effect before the next growing season. Both lime (which raises pH) and sulfur (which lowers pH) need months to work. If you put this off until spring your soil may be too wet and the soil labs get backed up with all the other last minute samples, so try to get this important task done this fall.

Adjusting Water pH and alkalinity improves the performance of pesticides and other products you use during crop production.  In high tunnels and greenhouses, injecting sulfuric or citric acid avoids nutrient tie up in soil and media.

Flooding in 2011 spread Phytophthora capsici into fields with no history of the disease. Growers who have not managed P. capsici previously could inadvertently and permanently spread the disease to additional fields and could experience high rates of crop loss due to improper management of the disease.  Understanding of P. cap will reduce the probability of these negative outcomes on eastern NY farms.
