Hulless Barley Response to Ethephon Application
Crop Management, 2007Ethephon [(2‐chloroethyl) phosponic acid] is commonly used in mid‐Atlantic barley production to reduce plant height and lodging, but is known to reduce grain yield and test weight in some barley cultivars. Management practices that produce high yield and good grain quality in traditional mid‐Atlantic winter barley have yet to be evaluated for hulless ...

AbstractEs wird eine gaschromatographische Bestimmungsmethode für Ethephon‐Rückstände beschrieben.Die Untersuchungen zum Rückstandsverhalten von Ethephon auf Süßkirschen ergaben nach Behandlung mit 0,05; 0,075 bzw. 0,1%iger Flordimex‐Brühe durchschnittlich 0,88; 1,45 bzw. 1,83 ppm in den Früchten.

Effects of ethephon on macadamia racemes
Journal of Horticultural Science, 1987SummaryEthephon sprays applied to Macadamia integrifolia trees caused the abortion of elongating racemes. The critical concentration of ethephon for early raceme damage was between 400 and 800 mg l−1. Dormant racemes were less sensitive, and rapidly elongating racemes more sensitive to ethephon damage.

Environmental factors affecting ethephon in olive
Scientia Horticulturae, 1978Abstract Inconsistent results of ethephon in field experiments in olive ( Olea europaea L.) are attributed to climatic differences and irrigation regimes. Physical measurements, using 14 C-2-chloroethyl phosphonic acid ( 14 C-CEPA) at pH 6.3 indicated 60% degradation within 5 h at 40° C.

Ethephon Advances Loblolly Pine Needle Cast
Forest Science, 1977Abstract Potted 1-0 loblolly pine seedlings sprayed with 5,000 ppm acid equivalents of ethephon in water in early July promptly abscised most of their year-old fascicles. Neither survival nor current-year needles were affected, and lateral branching was reduced.

Ethephon Alteration of Corn Plant Morphology
Agronomy Journal, 1989AbstractReduction in lodging, and plant and ear height resulting from ethephon application to corn (Zea mays L.) has been reported, but no attempt has been made to determine the influence of ethephon on internode properties and lodging. The objective of this study was to determine the influence of time and rate of ethephon application on plant and ear ...

Ethephon Elicits Protection Against Erysiphe necator in Grapevine
Journal of Agricultural and Food Chemistry, 2008The grapevine (Vitis vinifera) is susceptible to many pathogens such as Botrytis cinerea, Plasmopara viticola, Erysiphe necator, and Eutypa lata. Phytochemicals are used extensively in vineyards to reduce pathogen infections, but the appearance of pesticide-resistant pathogen strains and the need for environmental protection require the use of ...

Modeling ethephon-temperature interactions in cotton
Computers and Electronics in Agriculture, 1995Cotton (Gossypium hirsutum L.) growers are increasingly using growth regulators such as ethephon (2-chloroethyl-phosphonic acid) for crop management. Ethephon is widely used as crop terminator to facilitate early harvest. When applied on cotton, ethephon has been shown to have an effect on defoliation, boll opening, immature fruit abscission, and end ...

Thinning golden delicious apples using ethephon sprays
Journal of Horticultural Science, 1983SummaryIn southern Tasmania ethephon sprays were applied at two stages of bloom and after bloom at concentrations from 350 to 1 400 ppm. At both the balloon blossom stage and 42 days after full bloom (AFB) 350 ppm ethephon caused satisfactory thinning of fruit by decreasing fruit set and increasing the number of fruits 70 mm or more in diameter. Higher
