CWT Informational Meeting, Orchardists Focus On This Season’s Fruit (Continued from Page A 23) Krawcyzk. However the treatment also re quires washing of fruit, unless it is applied early in the season and al lowed to wash off by harvest time. George Perry, horticulture exten sion agent, covered sprayer calibrat ion. There are various ways to cali brate sprayers, he said, and he offered a simple way for producers to calibrate their equipment. One way to measure miles per hour on the tractor is to measure a distance of 88 feet. The producer should drive the tractor across the distance at the same speed that they will spray. Measure the seconds that it takes to go 88 feet, said Perry. The time is then divided into 60 to get the miles per hour. For example, if it takes IS sec onds to go the distance, and IS di vided into 60 is four, then the speed is four miles per hour. “There’s no such thing as a right speed or a wrong speed. It’s whatev er you are comfortable with,” said Perry. However “four miles an hour is pretty common and you’ll have good control.” At four miles an hour with a four foot-wide swath, the sprayer will cover an acre in 31 minutes. Perry also recommended setting the nozzle of the sprayer and then catch water for one minute. Multi ply the amount of water times 31, which equals the gallons per acre. “The most important thing is knowing how much water you’re going to need per acre. Get the gal lons per acre of water, then add your active ingredient,” he said. Record-keeping is important, according to Perry. “Over the years, pumps and nozzles change,” so not only calibrate your sprayer but keep your records, he said.

The main dwarfing rootstocks in the industry right now are the M 9, Bud 9, and the M 26 in apples. For intermediate size “the EMLA 7 rootstock is still the work horse for a semi-dwarf size tree,” he said. EMLA 111, EMLA 106, and Bud 490 are the large semi- dwarf root stocks. In addition, “there are several new Cornell rootstocks that are on the horizon that are known as the CG series but are still considered to be in the testing stage,” he said. Commercially available are CG 16, an M 9 size tree, and CG 30, an EMLA 7 size tree. “We (Adams County Nursery) recommend them only for trial purposes, mainly because we’re still trying to find their faults. “There are newer CG series that will replace them and will be com mercially available in the next 3-4 years,” he said. Backbone apple rootstocks are still the M 9, the Bud 9, a full dwarf; the EMLA 26 and the (M 91 EMLA 111 interstem) rootstock, a stronger dwarf. The EMLA 7 (EMLA 106), EMLA 111 are semi dwarf, according to Callahan. “The newer CG series that we’re looking at are the CG 41 (an M 9 size tree), the CG 11 (an M 26 size tree), the CG 935 (an M 7 size tree), and CG 707 (an M 111 size tree),” said Callahan. Other rootstocks that show promise are the Vineland series: V 3 (a size M 9 tree) that is fire blight resistant and the V 1 rootstock (an EMLA 7 size tree) that is also fire blight resistant and more preco cious it bears fruit at an earlier tree age. These rootstocks are commerci ally available on a limited basis this year, said Callahan. Management Policy Session, Lancaster Farm and Home Center, 1 p.m.-3 p.m., (877) 245-6442, ext. 8128.
