COMPRESS WSG is a plant growth regulator for use on container grown ornamental plants. When applied to the plant foliage COMPRESS WSG passes into the leaf, then moves within the plant to the growing points to reduce internode elongation. Treated plants will develop a shorter, more compact growth habit when compared to untreated plants.
FOR USE ONLY ON ORNAMENTALS GROWN IN COMMERCIAL OR RESEARCH GREENHOUSES, SHADEHOUSES AND NURSERIES. IN PRODUCTION AREAS NOT UNDER COVER, USE IS RESTRICTED TO CONTAINERIZED ORNAMENTALS.
- (Use on bed-grown or containerized ornamentals without impervious floors not permitted by the Arizona Department of Environmental Quality.)
- Use the DILUTION TABLE at the label to determine the amount of COMPRESS WSG needed for the required concentration.
The recommended application volume is 1 gallon of COMPRESS WSG spray solution to cover 200 square feet of area. This will provide foliage coverage just to the point of runoff.
Plants should be well watered prior to application of COMPRESS WSG. Wilted plants do not readily absorb COMPRESS WSG and poor results might be obtained if application is made to wilted plants.
The plant foliage should be dry when sprays are applied. Do not syringe or overspray the foliage for 18 to 24 hours after applying COMPRESS WSG to allow the chemical to enter the plant.
Two applications of COMPRESS WSG at 1/2 to 2/3 the label rates may give better control than a single application of the total recommended rate.
To reduce the elongation (stretching) of poinsettias, application of COMPRESS WSG should begin when new growth is 11/2 to 2 inches long.
Seasonably late applications will reduce plant height but may also reduce bract size and delay flowering. For growers scheduling early December flowering, applications should not be made after initiation of short days. As a guide, do not apply after October 1 for areas outside Florida, or after October 25 in Florida.
The recommended rate range is 0.20% to 0.30% (2000 to 3000 ppm). Use the 0.2% dilution in areas north of the sunbelt and 0.3% in the sunbelt. Vigorous growing varieties may require higher rates and repeat applications may be necessary for optimum plant size.
