MI spring peach meeting March 5

February 4, 2013  By Bill Shane Michigan State University Extension

February 4, 2013 – Peach growers are always looking for ways to improve their profitability and the 2013 Michigan Spring Peach Update is a good way to learn about this crop.

The meeting will be held March 5 at the Michigan State University Extension Southwest Michigan Research and Extension Center with registration starting at 8 a.m. and the program starting at 9 a.m.

The meeting will focus on fresh market peaches, including new peach varieties, insect management strategies, disease control, marketing strategies, rootstocks, farm marketing and mechanical peach thinning. Special guests include peach specialist Dr. Greg Reighard of Clemson University, award-winning peach grower Robert Fralinger of Bridgeton, N.J., National Peach Council director Kay Rentzel, MSU entomologist Dr. John Wise, and MSU plant pathologist Dr. George Sundin.

Deadline for early registration is Feb. 25. Registration is $30 per person or $25 for current Michigan Peach Sponsor members, with catered lunch included. Registrations mailed after Feb. 25 or at the door is $5 more per person. To pay in advance by check or money order, please download the registration form and mail with payment by Feb. 25. After this time, you may register at the door with check, money order or cash. Credit cards will not be accepted.

An important part of the meeting will be talks by Reighard and Chalmers Carr, a South Carolina peach grower and owner of Titan Farms. The presentations will focus on peach orchard mechanization and orchard design. Two relatively new blossom thinners – the tractor-mounted Darwin thinner and the Cinch handheld thinner – are changing how peach growers manage their plantings. The Darwin thinner has plastic strings along the length of a long revolving pole that remove blossoms, thereby reducing crop and increasing fruit size. This devise requires a flat, narrow peach canopy in order to do effective blossom -thinning. The Cinch, developed by Michigan native Phil Miller, uses the same concept, but with a shorter pole with a cluster of plastic tubes, the unit mounted on a hand-held, battery-powered drill.

The Cinch, although slower and more labour intensive than the Darwin, is handy for blossom thinning more traditionally shaped open-center and central leader trees because the operator can reach inside the center of the tree, which the Darwin misses. At the Spring Peach Conference, Carr will describe the experiences and refinements made by his crew with the 18 Cinch thinners they used in 2012.

Also at the meeting, Reighard will talk about blossom thinning strategies and how to train peach orchards to take advantage of the Darwin string thinner. Current orchard systems in favour for use with the Darwin are the perpendicular Y and the quad tree, both systems with scaffolds tilted into the drive row. The tricky aspect of the Y and the quad trees is training the trees to produce scaffolds at the proper height and orientation. Poor quality, slow growing trees are a big problem for producing Y and quad trees. Typically, the newly planted tree is headed at 1.5 to 2.3 feet from the ground to get side branches. A poor tree will be reluctant to push enough limbs to get good ones in the right position.
