Abstract In 1999 and 2002, pheromone traps were used to survey adult male codling moths, Cydia pomonella (L.) (Lepidoptera: Tortricidae), in commercial cherry (Prunus avium L.) orchards as well as adjoining pome orchards containing apple (Malus Xdomestica Borkh.) or pear (Pyrus communis L.). In 2002, sites containing isolated cherry trees and areas with no codling moth host trees were also sampled. Most codling moths were collected from pome orchards, whereas the lowest numbers were from the commercial cherry orchards. Fruit phenology data indicated that maximum codling moth flight was at a time when fruits were very immature. Cherries make a good candidate for the systems approach to quarantine security because few moths occur in commercial cherry orchards and, if fruit are infested, they would be too damaged to be harvested.
摘要1999年和2002年,在樱桃(Prunus avium L.)果园和邻近的苹果(Malus Xdomestica Borkh.)或梨(Pyrus communis L.)果园,采用信息素诱捕法对成年雄性冷蛾(Cydia pomonella (L.))进行了调查。2002年,还对有孤立樱桃树的地点和没有冷蛾寄主树的地区进行了抽样调查。在桃园中发现的冷蛾最多,而在商业樱桃园中发现的冷蛾最少。果实物候学数据表明,在果实非常不成熟的时候,冷蛾的飞行次数最多。樱桃是检疫安全系统方法的一个很好的候选者,因为在商业樱桃园中发生的蛾子很少,如果果实被侵染,它们将受到太大的损害而无法收获。

Abstract Apple (Malus Xdomestica Borkh.) trees planted in root-restriction bags provided an alternative to dwarfing rootstocks for control of tree vigor. Root restriction suppressed tree growth, reduced the need for pruning, and increased tree flowering, yield efficiency, and fruit color, firmness and soluble solids concentration. Root bags, with hole sizes of less than 2 mm in diameter restricted tree growth and root development more than desirable. Galvanized wire mesh was toxic to roots, limited root and tree growth, and caused significant leaf yellowing. Root bag materials did not inhibit root bag penetration or damage to the apples by voles (Microtus spp.). Only galvanized wire mesh (hardware cloth) and/or screen wire excluded voles from apples.

Abstract In a 3-year trial involving 30 ‘d'Anjou’ rootstock-training systems combinations, significant rootstock-training-system-induced differences occurred in all peel mineral elements measured. Variations in nutrient element concentration occurred among years. Significant combination X year interactions occurred in peel N, Mg, Mn, Fe, and Zn. No one rootstock training system combination was consistently either the “highest” or “lowest” for nutrient content for all the elements evaluated.

Abstract In a 3-year trial involving 28 ‘Bosc’ rootstock-training systems combinations, rootstock-training system induced differences were found in only three of the post-storage problem areas (decay, scab, and limb rub) studied for ‘Bosc’ pears. Significant differences occurred among years; however, no one year was considered “good” or “bad” for post-storage problems. Yearly patterns in post-storage problems varied with the problem. The significant differences that occurred between rootstock-training system combinations may have resulted from root-stock or training system combination effects on vigor or modification of the fruit nutrient content which was then related to the post-storage problem area. Significant combination X year interactions occurred for external cork spot and flesh browning. No one rootstock-training system combination had the greatest or least amount of any of the storage problems.

Abstract Georgia's peach [Prunus persica (L.) Batsch] industry has a long tradition, with the first peaches planted in the state more than 400 years ago and the first commercial production occurring in the middle of the 19th century. Peach acreage expanded considerably in the late 19th and early 20th centuries, resulting in an all-time high production of 236 million kg by 1928. Production, pest management, and marketing challenges that led to a consolidation of the industry during the second half of the 20th century are discussed. On the national scale in recent years, Georgia has ranked second or third in acreage and production of peaches. Although problem areas still exist, the industry enjoys important production and marketing benefits, most notably its proximity to large eastern markets and favorable prices due to early harvest and high-quality fruit production.

Abstract Prohexadione-calcium (Phd-Ca) (BAS 125W or 9054 W) applied at petal fall (PF) or within 10 days of PF to apple trees as a single spray or as multiple low-rate sprays reduced the current season's shoot growth. Sprays applied 2 to 3 weeks after PF were less effective. Timing of the initial spray was more important than rate in achieving early growth suppression, but rate was most important for maximum season-long growth control. Reduced shoot growth enhanced spray coverage and reduced dormant pruning time by as much as 23% over control trees. An effective cumulative dose (ECD) of 250 mg·L−1 (based on dilute or tree-row-volume equivalent) active ingredient Phd-Ca applied as a single spray or in several low-rate sprays generally produced season-long control of vigorous shoot growth. However, under some highvigor growing conditions a higher ECD (500 mg·L−1 or greater), applied in multiple low-rate sprays, was required to achieve an acceptable level of growth suppression. When shoots resumed growth in mid-season, a single spray (28 July) at 125 mg·L−1 provided additional suppression of shoot growth. During this 5-year study, there were no adverse effects on fruit quality and little or no effect on fruit size. There was no appreciable carryover effect on the next season's shoot growth or fruit size, and there was no additive effect from successive annual applications.

Abstract A delay in apple harvest caused an increase of fruit diameter, weight, price, and crop value, but allowed for increased fruit drop of ‘York’/MM.111. Economic returns for ‘York’ and ‘Golden Delicious’ were increased approximately 16% by delaying harvest by 3 weeks. Crop load of ‘Golden Delicious’/MM.111 trees (from 50 to 120% crop load) did not affect growth rate of fruit in the critical 6.1 to 6.4 cm diameter category. AVG did not influence the rate of ‘Golden Delicious’ fruit growth, but fruit were more firm and had higher starch levels, which allowed for a harvest delay compared to those not treated. Non-treated samples of ‘Golden Delicious’ taken from the same trees in 1997 and 1998 were 32 days more “advanced” in equivalent fruit firmness, 19 days in starch, 11 days in soluble solids, and 21 days in fruit diameter in 1998, thus demonstrating that in some years the normal harvest date could be delayed to gain additional crop value. Sprays of AVG delayed Gala/M.27 fruit ripening which allowed for an increase in fruit size; however, three sprays of Accel at 10 to 20 mm fruit diameter did not cause a delay in maturity or increased fruit diameter.

Abstract GA3, GA4+7 + BA or ethephon was applied in the spring or summer 1997, 1998 and 1999 to reduce secondary bloom in ‘Bartlett’ pear (Pyrus communis L.). Reduction of secondary bloom could reduce associated fire blight (Erwinia amylovora [Burrill] Winslow et al.) infections. The number of Type I secondary bloom was reduced by 400 mg·L−1 GA3, applied between 33 and 97 DAFB, dates which also reduced normal bloom and fruit set. Summer timings of GA3 at 100 mg·L−1 or GA4+7 + BA at 200 mg·L−1 reduced the number of Type V secondary bloom with no difference between GA3 and GA4+7. Ethephon applied one month after harvest in 1997 and 1998 reduced Type Vs in 1998 but not in 1999. Ethephon also reduced fruit set in 1999. Use of GAs to reduce Type V secondary bloom in a fire blight management program may be possible.

Abstract Aminoethoxyvinylglycine (AVG) applied 2–8 weeks before anticipated harvest significantly reduced preharvest drop of ‘Delicious’ apples. AVG did not affect fruit weight, and it lowered soluble solids slightly in only one of two years. AVG can be considered a legitimate replacement for daminozide for commercial use on ‘Delicious’ apples. AVG and daminozide were comparable in reducing preharvest drop and delaying ripening. AVGappeared to reduce watercore development more than daminozide, while daminozide was more effective at retarding flesh firmness loss on the tree.
