BEDDING PLANTS / FLOWERING PLANTS
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.
BEDDING PLANTS / FLOWERING PLANTS (Annual or Perrenial)
Excessive stem elongation of most bedding plants is prevented by a COMPRESS WSG spray made when 11/2 to 2 inches of new growth has developed after transplanting or pinching (approximately 2 to 3 weeks) or when the plants begin to elongate (stretch).
Repeat applications may be made when new growth begins to stretch.
To control the length of the peduncle (flower stalk) on plants such as Kalanchoe and Gerbera, apply COMPRESS WSG at a concentration of 0.12% to 0.50% (1200 to 5000 ppm). For Gloxinia, do not exceed 0.125% (1250 ppm) or injury may occur. Applications should begin 2 to 3 weeks after initiation of short days.
Note: Some varieties of Kalanchoe with cupped leaves have shown a sensitivity to COMPRESS WSG that results in slight phytotoxicity to the oliage. This phytotoxicity occurs when COMPRESS WSG spray solution accumulates, and therefore concentrates, in these cupped areas. To avoid possible phytotoxicity on such varieties, COMPRESS WSG solution should be applied during the late afternoon or evening, and the foliage should then be rinsed thoroughly with water the next morning.
To reduce leaf injury of petunias caused by air pollutant ozone and sulfur dioxide: Make a second application of 0.50% (5000 ppm) one week after the first. COMPRESS WSG will not protect against leaf damage caused by the air pollutant PAN. Growth retardation will be more pronounced and there may be a delay in flowering time from the second COMPRESS WSG application. Plants sprayed for pollution protection will be no shorter than those sprayed for compact growth.
