Re: [apple-crop] Southwest Injury
I would think apples and pears have a better chance of recovering than peaches or other tender fruit. It depends on how deep the split goes as well. In severe cold I have seen trees split deep into the heartwood, but its more common to see the only the bark to the cambium. Before trunk painting became commonplace (as well as milder winters), we used to tack the bark down - which excludes some insects and diseases. I was always surprised to see how much the split was able to join together. With some good TLC this season, the tree will be set back but can heal quite well. At one time, we used to say trees need to be 5+ years, but with nursery trees in short supply, it might be worthwhile to try to save younger trees. As Dave says, if you plan on grafting, the wood needs to be collected and stored soon. Don't throw it in an apple storage - ethylene is very damaging. Also, the grafting wax is very important to get a good seal. I'm not sure what is available on the market, so you should source that now too. Here are some old factsheets we have on grafting and repairs. Funny that we were musing if these are worth keeping :) Orchard Grafting Methods http://www.omafra.gov.on.ca/english/crops/facts/98-005.htm Repair Grafting http://www.omafra.gov.on.ca/english/crops/facts/98-003.htm I'm also wondering how much vole damage we will see when the snow melts.

Rosenberger Sent: March-16-14 10:48 PM To: Apple-crop discussion list Subject: Re: [apple-crop] Southwest Injury Hi, Greg - I'm really curious to hear what others suggest. Old-timers in northern NY would sometimes use shingle nails to nail the loose bark back to the trunks of big old winter-injured trees when the bark split away from the trunks due to cold injury during winter. I'm not certain if it did any good, but it might have helped to reduce further desiccation of the loose bark if it was not already killed all the way back to the point of attachment. Obviously, there is no value in nailing back dead bark. So long as there is still live bark on one side of the trees, you might be surprised to see how well the trees recover on their own if you can avoid crop load stress and drought stress for the next year. The damaged trees will never be quite the same, but my bet is that those trees that are not completely girdled will recover if they can be defruited or at least over-thinned this year. Concerning bridge grafting, it's pretty labor intensive, but I've seen it used effectively. Unless you have ideally placed root suckers already growing at the base of affected trees, you would need to gather the grafting wood immediately and refrigerate it so as to have dormant wood for grafting when the bark begins to slip a bit later in spring. Grafting will be more feasible if you had enough snow cover to keep some bark alive above the soil line. If bark is killed all the way to the soil line, you might instead consider inarch grafting with rootstock liners (if you can find any for spring delivery). These can be inserted next to the trunks with a needle-nose spade, stomped to backfill the spade slot, and grafted into the trunks above the damaged area sometime near petal fall after the liners have begun to grow. We did this successfully with some Delicious/MM.106 trees that were dying from union necrosis (ToRSV) back in the early 80s. In that case, we needed several liners/tree because the union was dying all the way around the tree. A single liner/tree might work OK if you still have live bark on one side. But as noted above, the tree may recover on its own if it is still alive on one side. As noted above, grafting is labor intensive, especially if it will be required for many trees/A as in high-density plantings. In addition to the labor required for grafting, additional attention is required to remove buds that will sprout on the inarch pieces and special care will be required to avoid hitting those tender graft pieces when applying contact herbicides.

Re: [apple-crop] Spray program software - Ontario AppleTracker
The Ontario Apple Growers are just releasing AppleTracker, a web-based record keeping software for Ontario apple growers. This is joint project with OMAFRA and DragonFly IT. Here is the article I recently wrote for our grower newspaper; Records - Are Yours Adequate? Let AppleTracker Help I asked this same question in my column last fall - are your records adequate? Although many types of records are required for CanadaGAP, spray records have the most extensive requirements. The latest revision of AppleTracker is here to help. The Ontario Apple Growers (OAG) received funding for the Farm Innovation Program and hired Dragonfly IT, to work with OMAFRA staff to improve this record-keeping software. You have seen this program before, and received your copy on CD a couple years ago, but it was challenging to customize for your farm. This newly released version is truly easy to use. Your farm is displayed as a map, showing individual blocks or rows of orchard (based on your ADaMS records). You enter set-up information on your sprayer equipment once. Spray events can be entered either before application (as a planning tool) or afterwards, by simply clicking and choosing from drop-down menus. All pesticide choices listed in Publication 360 are included, and you can enter others if needed. One big improvement is that the AppleTracker program is accessed through the Internet, and maintained by Dragonfly IT. They are updating both your farm maps from Agricorp and new pesticide registrations daily. Your data is protected by your password and for your use only, similar to doing web banking. The beauty of AppleTracker is the records you can choose to produce. You can print out records for individual blocks, individual cultivars, or for certain packers. And the format is based on the food safety requirements for CanadaGAP. An added feature is a notification of PHI and REIs that can be sent to your email or smartphone if selected. Additional modules will be added to the system in the coming months (for example harvest yields, shipping records and others). Learn more about AppleTracker through upcoming webinars and workshops being organized by the Ontario Apple Growers, who are providing this system access as a member benefit. Growers with email addresses on file with the OAG will receive their usernames and passwords in the mail by early March. www.appletracker.com/ Leslie Leslie Huffman 519-738-1256 leslie.huff...@ontario.ca lorchard.net] On Behalf Of Randall Steffens Sent: March 5, 2012 12:02 PM To: Blaine Bonnar; Apple-crop discussion list Subject: Re: [apple-crop] Spray program software Wow Blaine, this is exceptionally good news!

I asked a number of IT people how one might go about formatting such a document, and found surprisingly few who could offer me specific suggestions without things quickly getting very complex. In the end, we figured out that it's easiest just to take an unformatted text version (which is how I write up each week's issue), and then format the document with small page margins (0.2) and in a large type font (we use Calibri 24 pt), and save it as a PDF. This is what gets posted, and when you access it on a smartphone (regardless of the brand), it just opens in a full screen that you can scroll down as you read. We're tinkering with including some graphics like photos and tables, but this can require more effort to format I haven't gotten any feedback on this version yet, so I really couldn't tell you how many people might be using it.
