Annual bluegrass (Poa annua L.) is a problematic weed on creeping bentgrass (Agrostis stolonifera L.) putting greens. Annual bluegrass produces extensive seedheads in spring, and plant growth regulators (PGRs) are frequently used to suppress seedhead formation.

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 ...

Studies on the residual behaviour of Ethephon on black and red currants showed that the fruits contained on an average 0.39, 0.81, 2.2 and 0.64, 1.14, 1.04 p.p.m. of Ethephon, respectively, after application of 0.04, 0.06 and 0.08%. Flordimex mixture. When a concentration of 0.08% was applied to gooseberries, the fruits contained on an average 0.31 p.p.

Ethephon and the Delay of Early Budding in Chrysanthemums
Journal of Horticultural Science, 1979SummaryDelayed flower bud formation was recorded when a single spray of 200 ppm ethephon was applied to rooted chrysanthemum cuttings three days after planting in long days. The cuttings were of three American garden cvs and an autumn-flowering cv known to bud readily in long days.

Ethephon and Nitrogen Use in Winter Wheat
Agronomy Journal, 1989AbstractThe plant growth regulator ethephon ([2‐chloroethyl] phosphoric acid) has often been used to reduce height and lodging of intensively managed soft red winter (SRW) wheat [Triticum aestivum (L.) em. Thell]. The effect of ethephon on traits that determine grain yield has not been widely studied.

Effect of Ethephon on Dormancy Breaking in Beechnuts
1997The ability of ethephon to reduce the cold requirement of dormant beechnuts was investigated. Several pretreatment methods were tested applying ethephon solutions at different concentrations and different cold durations to 3 seedlots. Ethephon strongly stimulated both germination percentage and rate whatever the cold duration but ethephon application ...

Spring Wheat and Barley Responses to Ethephon
Agronomy Journal, 1988AbstractEthephon [(2‐chloroethyl) phosphonic acid] has recently been introduced in North America as a regulator to control lodging in cereals. A 3‐yr study (1983‐1985) was conducted to determine how widely grown spring wheat (Triticum aestivum L.) and spring barley (Hordeum vulgare L.) cultivars in the North Central United States responded to ethephon.

The authors describe a gas chromatographic method for determing Ethephone residues. Studies on the residual behaviour of Ethephon on sweet cherries showed that the fruits contained 0.88, 1.45 and 1.83 p.p.m. of Ethephon after applications of 0.05, 0.075 and 0.1% Flordimex mixture, respectively.

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 ...

The potential uses of ethephon in apple growing
Annals of Applied Biology, 1975ABSTRACTThe effects of ethephon on growth, fruit bud formation and abscission in apple will be discussed in relation to the possible use of this chemical in orchards. It is possible, for example, to accelerate the ripening of fruit on trees and yet avoid abscission effects by combining ethephon with other growth regulators.
