Page 12—Grower and Marketer, Lancaster Farming, Saturday, May 20, 2000 The Farmstand: Direct / Maifcettagj^^P^ 2000 SUMMER ORCHARD TOUR JULY 18-19 This year we will be having a summer orchard tour in the south central area of the state in cooperation with the State Horticultural Association of Pennsylvania. The dates are July 18-19. The tour will start at 10 a.m. at Strite’s Orchard just out side of Harrisburg. After that we will be traveling, by per sonal vehicle, down to Adams county for stops at orchards and markets in that area. Stops in Adams county on the 18th will include Weiser’s Orchard and Farm Market and Adams County Nursery Orchards. Tuesday evening we will have a picnic supper at a local park. On Wednesday, July 19, we will visit Hollabaugh Brothers Orchards, Market and Storage, Bear Mountain Orchards and Packing House, Knouse Foods’ Coop erative at Peach Glen, Rice Fruit Company Packing House, and R&L Orchards. The Days Inn in Gettys burg has set aside a block of rooms for Tuesday night. We have also reserved three buses for Wednesday. On Tuesday travel will be by your personal vehicle. On Wednesday we will have air conditioned motor coaches to transport the group. Regis tration for the tour will in clude dinner on Tuesday night, bus transportation on Wednesday and lunch on Wednesday.

If you have patches that are doing poorly, dig up some plants from these areas and slice through the main roots lengthwise. One diagnostic symptom of red stele (Phytophthora root rot) shows up when the soil is cool, and becomes less obvious as the soil warms. If the plants have this disease, there will be a reddish disco loration in the center (the stele) of the root. Also, check for root weevil larvae (small white grubs) in the top inches of soil. Slice through the crown of the plant, too. You may find tun nels made by grubs or the grubs themselves. The crown should be creamy white throughout. If you notice a brown or reddish discoloration, the plants may have been cold-injured, though some diseases also cause discolorations of the crown. Starting before bloom, check weekly for tarnished plant bugs (they cause but ton-berry) and clipper. Sample in a V-shape across the field. For tarnished plant bugs, tap at least 30 flower clusters over a white plate. More than 0.25 nymphs per cluster before 10 percent bloom or more than 0.5 nymphs per cluster during mid to late bloom are the thresholds for a spray appli cation. Insecticide sprays during bloom are to be avoided if at all possible be cause of risk to pollinators. If no tarnished plant bug nymphs are found until mid bloom, delay spray applica tion until after bloom to protect pollinators. For clipper, check 5 to 10 - 2-foot sections of row. An av erage of 1 clipped bud per foot of row is the threshold for control. If your planting borders woods, check some additional sections in the border rows near the woods. Sprays of these border rows may be sufficient.

The ever increasing number of deer in the commonwealth poses a severe threat to the profitabil ity of any produce operation. First a few deer facts: Deer will eat anything if they are hungry enough. There was a time when the author believed that garlic was completely out of the question, but hungry deer will even take an occasional bite of garlic. A little deer math: start with a hypothetical herd of 24 deer eight are bucks and 16 are does). Now use some method of effective hunting: six bucks and eight does are harvested during hunting season. This leaves two bucks and eight does for this coming breeding season. Each doe has 1.7 fawns on average in good habitat. We now go into next season with 23 deer and this is after kill- IDEAL for FARM MARKETS: BAKING MIXES: In Fowler’s Mill Cloth Bags: 6 Pancake Mixes 5 Muffin Mixes 4 Fruit Mixes (the consumer adds fruit) In Private Label Paper Bags (consumer adds fruit): 4 Apple Mixes (crisp, cake, muffin, pancake) 3 Peach Mixes (crisp, cobbler, muffin) 3 Cherry Mixes (crisp, cobbler, muffin) 7 Other Mixes (shortcake, pancake, biscuit) Fowler’s Milling Company • Chardon, Ohio Call 800-321-2024 ing more than half of the herd. No amount of deer control is effective long term without intensive herd population management as ever increas ing numbers of deer will overwhelm any barriers we create. Repellents don’t work, at least for very long. There are numerous repellents on the market. Most will work for a short period, but seldom for more than 2-3 weeks and most need to be reapplied regularly. Hungry animals have been shown to pay little attention to repellents. Some methods of deer con trol worth consideration: •Radio-collared dogs. Cor nell evaluated in one research project a greatly beefed-up dog radio collar system called off-limits. This system has been shown effective on areas as large as 30-50 acres per en closure depending on terrain, dog’s abilities, and desired control levels. Since dogs are highly territorial, they essen tially stake out the area as their own and will chase any varmints or deer from inside the antennae area. Selection and training of the dogs as well as the placement of shel ter, food and water sources is imperative for this to work well. Dogs that are not used to people may be a problem in “pick your own” opera tions. Some dogs tire of the chase without ever catching the deer and quit chasing them. Cost: approximately $4,000 for 30-50 acres. •Full-height barrier fences. Nothing beats a full height (8-10 foot) fence for deer con trol. If you can afford to sur round a planting with a barrier that deer cannot get over, under or through you’ve got good deer control. The big problem with this method is short and long term cost. Initial installation is expensive as even inexpen sive plastic mesh materials can run $1 per foot, 10-12 foot posts are not cheap and annual maintenance can be time consuming. •Slant fence. Slant fence systems using high-tensile wire and an electric charger are quite effective, as deer do not readily jump over a bar rier with depth. This five foot tall fence is up to eight feet deep. Drawbacks to this system are the initial cost of installation and the need to maintain a weed and grass free strip under the fence. •Low-cost two-wire elec tric fence. Baited, low-cost, polywire fencing can provide highly effective deer control with minimal capital outlay. A typical polywire fence of this type has two wires on fi berglass posts set at 20-30 foot spacing. The top wire is 30-36 inches off the ground and the low wire is 18-20 inches off the ground. Pieces of aluminum flashing that resemble pup tents are crimped along the top wire at 10-15 foot intervals. Peanut butter is then smeared under these tents. The wires are charged and when the deer come to investigate the (Turn to Pago 13)
