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 retard spring forcing growth, spray with a 0.50% (5000 ppm) solution of COMPRESS WSG when the new growth has just started to unfold and 4 to 5 pairs of leaves are visible. Apply 2 to 4 weeks after the start of forcing but not later than this time.
For those greenhouse varieties that produce excessive growth during the summer following pinching, spray to runoff with a 0.75% (7500 ppm) solution of COMPRESS WSG when the regrowths are 1 to 2 inches in length, usually in late July, but not after the first week in August.
