Two different pest control programs were applied on 8-year-old 'Ryoka'/M.26 apple trees (Malus domestica Borkh.). Lime sulfur or Bordeaux mixture with emulsified oil were applied 12 times from late March to mid-September as organic treatment, and synthetic chemicals were 7 times applied as control...

Sunburn is a major type of solar radiation injury that leads to significant economic losses in several fruits, including apples. Here, the efficiency of a new product, called 'Sun Protect', in protecting apples (cv. Granny Smith) against sunburn was tested. The effect of 'Sun Protect' application...

The effect of two-spotted spider mite populations (Tetranychus urticae Koch) on the yield and growth parameters of the early-season apple cv. Katja was evaluated during a 3-year study. In the case of the colonisation of apple trees exceeding 1,462, 2,760 and 1,548 cumulative mite days (CMDs) in the ...

This proceedings contains 12 papers focusing on the benefits of the use of copper as a fungicide in the control of fungal pathogens in horticultural crops, such as apples and grapes. The risks associated with prolonged copper fungicide use to man and the environment are also discussed.

A comparison trial of 23 apple scab resistant cultivars was started in spring 2009. The trial was located in southern Estonia at the Polli Horticultural Research Center (58°07′N, 25°32′E). Trees were grafted on dwarfing rootstock B396 and planted in an orchard with the distance 2×4 m (1250...

The effect of the essential oils of thyme (Thymus vulgaris), cinnamon (Cinnamomum verum) and sweet orange (Citrus sinensis) on conidial germination of Venturia inaequalis was investigated in vitro. Moreover, the effect of cinnamon oil was further studied by analyzing its preventive and curative...

Various types of unit packaging methods were applied for 'Fuji' apples during short-term cold storage and export simulation. Gas tightness of the package was controlled stepwise in the successive two-year experiments using different perforation treatments (none, punch hole, or pinhole) and sealing...

This study aimed to evaluate the fruit quality characteristics and incidence of flesh browning in response to air storage at 0±1°C after controlled atmosphere storage (CA condition: O₂ 2.5±0.5%, CO₂ 1.5±0.5%) at 0±1°C in 'Fuji' apples (Malus domestica Borkh.). The storage system was performed as...

The measurement of ethylene concentration in the apple core is considered a good method of determining OHD, but requires high accuracy and expensive equipment. The measurement of ethylene production seems to be a technologically easier method. During research conducted in the years 2003-2008,...

The iron has a very important role in the growth and development of the plant, iron deficiency causes chlorosis in apple trees. The main producing areas of apple in China just iron deficiency, therefore, filter out iron-efficient resources from rich apple germplasm resources, and breeding new...
