APPLICATION VOLUMES AND SPRAY COVERAGE:
Thorough spray coverage is essential to achieve maximum product effectiveness. Spray coverage is affected by choice of equipment, nozzle selection, and spray boom setup as well as spray pressure, plant size, and canopy density. For both air and ground applications, it is important to choose an equipment setup that will assure thorough coverage of plant canopy (foliage and fruit). The actual spray volume required will vary with the size and density of the plant canopy and the equipment used. In California and Arizona, use a volume of no less than 5 gallons per acre for aerial applications.
DO NOT MIX QUALI-PRO ETHEPHON 2 SL WITH AMMONIUM THIOSULFATE. SUCH TANK MIXTURES MAY RESULT IN FORMATION OF TOXIC FUMES.
Mix only the amount of spray you expect to use each day. Do not allow mixed solution to stand overnight. Avoid spray drift to nearby crops as this product will cause modification in plant growth. Plant injury or reduced yields will result. Do not plant another crop within 30 days after treatment. Do not use Quali-Pro Ethephon 2 SL with additives other than recommended on this label. Avoid spills of concentrated product on spray equipment or airplane parts. IMMEDIATELY RINSE ANY SPILLS WITH PLENTY OF WATER, AS QUALI-PRO ETHEPHON 2 SL IS CORROSIVE.
Quali-Pro Ethephon 2 SL will remove dwarf mistletoe shoots in ornamental conifers and leafy mistletoe from ornamental deciduous trees.
UNDESIRABLE FRUIT ELIMINATION (For Use Only on Ornamentals):
Quali-Pro Ethephon 2 SL will reduce or eliminate undesirable fruit development on apple, crabapple, carob, and olive trees.
*This recommendation is not intended to be used on commercial fruit production as a thinning agent.
Quali-Pro Ethephon 2 SL is a plant growth regulator that may be used to suppress the formation of seedheads of various plants including Poa annua and white clover. It may also be used to suppress the growth of certain cool season grasses. Quali-Pro Ethephon 2 SL is foliarly absorbed and is most effective on actively growing healthy turf. For best results, apply in sufficient volume of water to provide uniform coverage. Use of spreader/sticker with an application of Quali-Pro Ethephon 2 SL is not necessary. Quali-Pro Ethephon 2 SL is rainfast within 2 hours. Do not allow entry into treated area until Quali-Pro Ethephon 2 SL has dried. For maximum performance, delay mowing until the day after application.
Precautions and Restrictions:
Seedhead Suppression: Foliar application of Quali-Pro Ethephon 2 SL will provide suppression of Poa annua and white clover seedheads. Make the initial application prior to the emergence of new seedheads. A period of 2-3 weeks after application is required for maximum performance. Repeat applications may be made to predominately Poa annua or white clover sites as needed, but not less than two weeks after the previous application.
Poa annua and White Clover Seedhead Suppression: 5 fl. oz./ 1000 sq. ft. - 1 to 2 gal per sq. ft.
Reapplication interval: 2 weeks or greater for all labeled grasses.
*Do not use in California on greens, tees, or Bermudagrass unless accompanied by supplemental labeling.
Tank Mixture with Products containing the active ingredient Trinexapac-Ethyl: Tank mixtures of Quali-Pro Ethephon 2 SL at 5 oz./1000 sq. ft. and trinexapac-ethyl-containing products such as T-NEX or Primo MAXX at 0.125 or 0.25 oz./1000 sq. ft. can be used to promote seedhead suppression as well as turfgrass quality. Multiple applications of the tank mix combination may be needed. The number of applications must not exceed recommendations for rates or timings for either product applied once. Follow the recommendation on each product label for the most restrictive application interval for each turfgrass. Application of this tank mixture during frost periods may cause temporary turf discoloration.
Growth Suppression: An application of Quali-Pro Ethephon 2 SL slows the growth of turfgrasses, thus reducing the required frequency of mowing and the volume of clippings collected. For best turfgrass growth regulation, apply Quali-Pro Ethephon 2 SL when daytime air temperatures are 65 degrees F and rising. Quali-Pro Ethephon 2 SL should only be applied once turfgrass mowing heights have been established for the season. Avoid multiple applications of Quali-Pro Ethephon 2 SL in areas where excessive thatch has accumulated.
Turfgrass Growth Regulation
Rate: 5 fl. oz. per 1000 sq. ft. - 1 to 2 gal per sq. ft.
Do not contaminate water used for irrigation or domestic purposes. Do not apply directly to water, to areas where surface water is present, or to intertidal areas below the mean high water mark. Do not contaminate water when disposing of equipment washwaters. Avoid spray drift to nearby crops, as this product will cause modifications in plant growth. Plant injury or reduced yields may result. Do not plant another crop within 30 days after treatment. Drift and runoff may be hazardous to aquatic organisms in water adjacent to treated areas.

and T-Nex are both plant growth regulators; however, they have different active ingredients and are labeled for different uses. Ethephon SL is also labeled to disrupt the growth of any unwanted fruit in certain trees such as crabapple, apple, olive, and carob trees. It is also formulated to eliminate dwarf and leafy mistletoes. Ethephon SL is to be applied by professionals for agricultural and commercial use and is not for residential purposes.
T-Nex is labeled to reduce the growth of cool and warm season grasses while helping improve their quality and stress tolerance. This is labeled for residential use.
What is the difference between T-Nex and Ethephon? They seem to do the same thing?
Ethephon 2SL has a 3-5 year shelf life when stored properly (out of direct sunlight and away from extreme temperatures).
