Las pérdidas de producción ocasionadas por el asoleado de frutos en manzanas y peras son elevadas en la mayoría de las regiones frutícolas del mundo. Evaluaciones locales indicaron para la temporada 2002-03 pérdidas de calidad de manzanas exportables de entre un 15 y 55 % según la variedad, determinando una sustancial merma tanto en la cantidad como en la calidad de fruta exportable y comercializable.
The history of the Kershaw Companies in the Yakima Valley began more than 125 years ago when our family headed west from Philadelphia and one of the eight children in the family, my great, great grandfather Robert Kershaw, decided to settle in the Naches Valley. Originally, Robert Kershaw focused on raising cattle, but the expanded availability of irrigation water following the passage of the Reclamation Act of 1902 encouraged him to move into fruit ranching. We started with pear orchards and added apples shortly thereafter.
Testing of Eight Medicinal Plant Extracts in Combination with Kresoxim-Methyl for Integrated Control of Botrytis cinerea in Apples
Botrytis cinerea is a fungus that causes gray mold on many fruit crops. Despite the availability of a large number of botryticides, the chemical control of gray mold has been hindered by the emergence of resistant strains. In this paper, tests were done to determine the botryticidal efficacy of selected plant extracts alone or combined with kresoxim-methyl.
Modern orchards are being developed with small (dwarf) trees at close spacing. The proper distance for setting the trees varies with the variety selected and the fertility and water-holding capacity of the soil.
