Re: Apple-Crop: Spring 2008
Here in Maine we have about 3' of snow on the ground topped by 1/2 of ice. We have bloom usually towards the end of May. Your are right about the chemical input expenses. They just spiral upwards. The best we can do is to do a good job of soil and leaf analysis and only use what is required. For pest and disease control we do IPM. It's the best we can manage. Dwarf trees help. In my opinion organic is a poor choice for us. Too many trips spraying (30 or more) and too much material(especially sulfur, which can't be good for the soil). Our primary variety is McIntosh which is susceptible to apple scab. Thankfully, we don't need to apply much Nitrogen. Often foliar will do. Smartfresh has made a big difference for us. There seems to be an improving market and a sense of optimism that I have not experienced in many years. Our labor is mostly H-2A (Jamacian) and is experienced, skilled and reliable but very expensive. We had our best crop in several years in 2007 but can only hope for a repeat in 2008. Art Kelly From: Con.Traas To: Apple-Crop Sent: Thursday, February 14, 2008 10:51 AM Subject: Apple-Crop: Spring 2008 Hello all, We are experiencing a lovely warm spell for this time of the year, and St. Valentine's Day. Although warm, the trees are not so advanced as they were a few years ago, when the first Victoria plum trees started flowering at this time. So, at the moment it looks as though (assuming the weather does not remain warm for too long) we will have an early spring, but not one for the record books, which is a relief, as we have often had damaging frosts in early May, which is still a long way off. On our own farm we still have apples in store, and thanks to the Smartfresh treatment, they are really excellent. In fact, they seem to stay that fresh that I need to add far fewer high-acid apples to my juice to get a nice balance between sweetness and acidity. My only problem is to figure out what to do with the high acid apples. In general growers were happy with apple demand this year, but are very concerned about the rising costs of fertiliser (linked to oil prices it seems), and agrochemicals. However, labour is still the number one cost, and it looks likely to remain that way. At least in Ireland it is possible to get labour, whereas in the UK and Holland, it can be very difficult. I would be interested to hear what prospects are like in other parts of the World, and how the spring is shaping up. Right now I've got to go out and do a bit of work. Con Traas

Art Kelly - Original Message - From: Renae Moran To: apple-crop@virtualorchard.net Sent: Monday, March 17, 2008 2:25 PM Subject: Apple-Crop: position available Apple Orchard Manager Position We currently have an opening for a farm manager in our operation. We are Ricker Hill Orchards, a family farm in Turner, Maine, started in 1803. Our apple orchards are located in seven towns in Maine's western foot hills. We produce IPM and organic apples, high bush blue berries, IPM cranberries, and other fruit and mixed vegetables to a much smaller degree. We employ five orchard managers who each manage and maintain 50 to 120 acres of apples. The farm manager spends most of their time on the same farm, pruning, mowing, spraying, and managing the harvest crew. Decisions on chemical control for pest and disease management and thinning are made by the owner. General farm workers are available when extra labor is needed. Record keeping for each farm is done an individual enterprise with expenses and income from the quality and quantity of crop. Managers must be available to work when needed to grow the crop to its top potential. There will be some flexibility on work schedule. Occasionally the manager will work with our packing operation, cranberry operation, or helping on one of the other manager's farms, as needed. This position involves some excessive hours during May/June and September/October. Our regular work week is Monday through Friday, 7 am to 4:30 pm. Base salary is between $27K and 35K, commensurate with experience and education. Manager's share of profits from their farm is 10% up to $10,000. Benefits include a medical and retirement plan, vehicle and clothing allowance. Housing may also be available.

As a rule of thumb, they require about twice the pressure versus a standard nozzle. Generally about 80 psi, but be sure to check the specs and try to operate them in the middle of their pressure range. Gallons per acre shouldn't change. Spray the rate and volume that's worked for you in the past. Nozzling your sprayer with ai nozzles is the same process as with any other nozzle. Work out your desired output for one boom and divide by the number of nozzles. As for row spacing and tree size, again, you should spray the volume and rate that's worked in the past using conventional nozzles - your method needn't change. Again, these are just rules of thumb, but try not to drive faster than 5 km per hour and don't spray less than 500 litres per hectare.

It is also true that most of the new materials are not as directly toxic to the flies as the OPs, and the efficacy of many these new materials appears to be due to their ability to prevent flies from ovipositing as long as they are in contact with their residues. We really don’t know the mechanism of this mode of action, but in many laboratory bioassays the flies will not lay eggs on treated apples, although they remain alive. So far, we would say that in most normal US orchards, which are presumed to be initially free from internal AM infestations and are not near abandoned orchards and other large sources of unsprayed host trees, we have not seen control failures or even increased damage in orchards that are not treated with organophosphates, although AM catches in monitoring traps placed along the edges of these orchards appears to be higher than when they were sprayed with organophosphates. As far as efficacy, Calypso is definitely the most effective of the new insecticides, followed by Assail. Delegate and Altacor also have some activity, but would probably not provide control in orchards with internal infestations or those that are near heavy unsprayed sources of infestations.

I suppose that if the systemic activity of neonics is sufficient to kill Apple Maggot eggs or larvae during a (two week?) period after application, and up to 2 inches rainfall, they could be expected to be as good as Imidan or Guthion, regardless of whether the adults are killed by fruit or foliar contact. Or, perhaps female flies are killed by ovipositor contact with systemic neonic during egg insertion? My guess is that such studies have not

Re: [apple-crop] honeycrisp management
Interstems do make for a more expensive tree. Wasn't the thinking always to use interstems for a free standing, supported early years, well anchored but smaller tree?

We use 1/2 rate from both sides for the coverage as opposed to full rate both sides. Also you can mix for one block and then either add the water or more material for the other block.

Re: [apple-crop] horticulture
Yes, it is relatively high density, Spencer and Honeycrisp on M26 at 5 X15. The limbs average about 2 in diameter and the leader is around 3. Some of the trees have 2-3 of these large limbs. When I pruned them in 2014 and pruned out the highest big limb I often got a vigorous upright shoot that I don't think is going to make a suitable renewal limb. We are talking random trees so the task of maybe spreading these shoots is easily overlooked. I was thinking that if I pruned out the lowest big limb that maybe there would be a little more suppression of that renewal shoot and it would grow at a wider angle and less vigorously.

Assuming this is a high density planting and you like where the branch is placed you can make a “dutch” or bevel cut to renew and weaken the branch. If you have to choose between the two the higher limb would be my first choice.

If you have some trees that have developed some overly large limbs (50% of the diameter where it joins the leader) in the bottom of the tree should you prune out the highest large limb or the lowest large limb, not wanting to prune them all out for fear of over invigorating the tree? I'm heading out to prune now after some paperwork.
