Re: *Potential Spam* RE: Apple-Crop: Attaching trees to trellis
Bill, Unfortunately, I have been unable to find any commercial source for the Garden Dig-It unit your link describes. I suspect it is no longer on the market. That would argue in favor of a home manufacture approach to obtaining one. Years ago, when we were doing pre-plant soil fumigation for orchard replant problem control, we made soil probes using standard pipe and fittings. We used 3/4 or 1 pipe, a threaded T for the input and 90 o output w/ a short 6 stub (capped) on the far side of the T to provide an additional hand access point to press the probe down into the ground. The long (business) end of the probe was a 42 length of pipe that was screwed into the T. The bottom end of the long pipe had a 2 - 3 length bolt w/ the threads ground off, just the right diameter to fit inside the long pipe and the bolt head built up to a tapered round-pointed tip to enable penetration into the soil. The bolt had an elongated oval slot (~0.5 length x 1/8 width) cut through the shank starting at about 1 above the bolt head; then a single 1/8+ diam. hole was drilled through the bottom of the long pipe at ~1 above the bottom end, the modified bolt inserted into the pipe and turned so that the holes lined up, and a 1/8 diam brass rod pushed through the holes (to allow the end bolt assembly to slide back against the bottom of the pipe to seal it when pushed into the ground and to allow the bolt to slide out from the pipe to open the pipe end when jerked back up after the probe had reached the desired depth for fumigant application -- allowing the fumigant to disperse from around the bolt shank in the pipe into the surrounding soil). We even added a brass ball-valve on the inlet side to allow us to shut off the fumigant once we finished the injection so the fumigant wasn't spewing out of the tip under pressure as we pulled the probe out of the ground. The root-needle fertilizer injector units available from the garden centers have a very similar design (but much smaller and no effective shutoff valve) that allows the water pressure to drill the probe's path down into the root zone. I do have photos ( diagrams) - somewhere in my computer 35mm slide collection - of the probes we made. The question would be how to get them on the web. I'm pretty unskilled at that aspect of webpages -- I suppose I could send them to Jon Clement and he could post them and provide a link. If there is interest in that, I will look for them. My point is that the probe you are talking about for hydro-drilling could easily be made in a similar manner. The difference would be in the pipe bottom structure. Instead of being a sliding tip, one might find a solid tip with a central hole would work better??? One could simply plug the pipe end with a piece of tight-fitting rod w/ a central hole drilled in it to provide an outlet for the water. I suspect one would need to have some lateral outward downward-angled holes to facilitate a lateral drilling function. Any thoughts on how the bottom of the probe/drill should be designed for maximum efficacy / drilling efficiency? The photo in your link looks to have a straight-shot stream coming out of the probe bottom end. Harold L. -- Dr. Harold Larsen Res. Pathologist Ext. Fruit Dis. Specialist Colo.

I used a 400 gallon air blast sprayer, fan turned off, pressure set at 80 psi. The hose to the drill needs to be at least ¾, preferably heavy duty enough to drag around rough ground. With a 100' hose I could drill holes 5-6 rows on either side of the sprayer before it needed to be moved. 75-100 holes could be drilled per 400 gallon tank. The way you form a pipe into a point is to first cut a series of touching triangles out of one end. You end up with a jagged edge that looks like a crown. Then just hammer the triangles inward so the edges and points touch, weld together. **/Bill Fleming/** **/Montana// State University/** **/Western Ag Research Center/** **/580 Quast Ln/** **/Corvallis//, MT 59828/** **/(406)961-3025/**
Apple-Crop: Re: a question about bud terminology
The discussion about TRV has been most interesting, but I have another question about bud terminology. Within the Rose family, we have crops that have differing types of flower-containing buds: - a single flower, no shoots -- Apricot, peach, and nectarine (plus some individual buds on plum) - multiple flowers, no shoots -- sweet tart cherry (+ other cherries), plums (most buds) - multiple flowers + shoot initial -- apples pears The first category, I believe, is termed a simple bud. The third category, I believe, is a type of compound bud termed a mixed bud But what is the plant anatomical / horticultural term for the second category? I had viewed it as a compound bud because of the multiple flower initials, but the typical example used for a compound bud is grape (Vitaceae) which has a primary, secondary, and tertiary bud all enclosed within the bud scales at each node. I have NOT been able to find any source of reference with a term for the cherry and plum type of complex bud. Any ideas / references out there??? I have been putting together an Extension document on evaluating cold injury damage to fruit buds and the evaluation process differs between the bud types. So use of some terms would be helpful in shortening it. The intent is to have it both in printed form and as a PDF document on the web. So I'd really like to have the terminology to be correct!

Re: Apple-Crop: Apple maggot in plums
Lorraine, You might have a different species of Rhagoletes fruit fly instead of the apple maggot species. You might be able to obtain adult flies to ID by placing the infested fruit onto moist, sandy soil put a plastic bag in a box to allow the larvae to finish growing and then crawl out of the infested fruit and down into the moist soil to pupate. Once the pupae are formed, you can keep them in a cool room for a couple of months (some of our entomologist participants may have more info on specifics here), sieve the soil to harvest the pupae, and then store them at room temperature in a screened lid container to let the adult flies emerge from the pupae. Once you have adult flies, compare the wing patterns. The wing patterns for Rhagoletes species are pretty specific and comparison with wing patterns for the emerged adults should facilitate a correct ID.

Re: Apple-Crop: deer
An interesting idea. One would need to keep weed growth within the flat fence area under control so that it would be obvious to those animals that might be considering traversing it. Any idea on what the necessary border strip width might need to be? Raccoons probably wouldn't need more than 3-4 ft, but deer can jump much further than that. I suspect bear likely would not be to comfortable with it either! -- Dr. Harold Larsen, Interim Manager - WCRC Res. Pathologist Ext. Fruit Dis. Specialist Colo.

Re: Apple-Crop: Re: Pristine apple tree
Dave, The reason for my comment was that very small, bumpy, deformed apple fruit can be the result of rosy apple aphid feeding on young fruit at early stages. Campyloma bug feeding on young fruit also can cause deformed fruit. Both are problems best addressed by entomologists within our audience (rather than me, a plant pathologist). However, the restriction of the symptoms to just the Pristine with the Sundance apples immediately adjacent being unaffected would argue against an insect cause, I would think.

The fruit tend to be oblate shaped and with distinct lobing that makes them look a little misshapened. I suspect if pollination isn't optimum, that trait may be pronounced. Harold may be on to an important issue as well. Further, I was not impressed by the quality of fruit early, but over time I learned its peak maturity and have become a fan of it as an apple for fresh eating. I've given them away to a number of people in recent years to learn their response and have had only favorable responses. So I think it's an apple that needs a little patience and a learning curve, but is rewarding in the end. Its certainly become a consistently good apple in that maturity window, which has little else to offer in northern Illinois. Bill I planted Pristine, Sundance and Pixie Crunch in 2002. I am having consistent annual problems with the Pristine. Despite what is implied by its name, I am having a uniquely bad apple quality from this tree. Spray schedule: 1/ dormant oil 2/ Fertilome Blight Spray (streptomycin) was applied during bloom. 3/ Following bloom drop - every 7 - 10 days with Imidan and Captan. Every year, the fruits are notably irregular shaped, bumpy and malformed. They are certainly not smooth and pristine. They are the only variety out of 20 I have that do this. And the malformation is noticeable when fruit is just forming - finger tip sized. Any idea what is causing this? Everything else about the growth of this Pristine Apple is fine. Thanks.

Re: Apple-Crop: Ethryl
Interesting variation on spelling of the material. Here it is spelled Ethrel. To my understanding, its use here in Colorado is more to enhance return bloom (I think by enhancing thinning in conjunction w/ other thinners prior to flower initiation -- but I could easily be wrong on that).
