Achieve Long Lasting Weed Control in Citrus


Get Ahead of Your Broadleaf and Grass Weed Control with Solicam® DF

Solicam® DF pre-emergence herbicide provides long-lasting, grass and broadleaf weed control in citrus. When applied prior to seed germination, SOLICAM enables growers to get ahead of their weed control.

Product Information

SOLICAM DF must be moved into the weed seed germination zone to be effective. If no rainfall occurs within 4 weeks after application, the product must be incorporated by flood or sprinkler irrigation. SOLICAM DF has no postemergence activity and will not control established weeds. Existing weeds must be mechanically removed or controlled by using a suitable postemergence herbicide.

Multiple or sequential applications can be made, but the total quantity of SOLICAM DF applied within a year must not exceed the maximum recommended rates in the Maximum SOLICAM DF Rates table below or in the specimen label.

Key Benefits

  • Provides pre-emergence control of some of the toughest broadleaf weeds and grasses in citrus orchards.
  • Provides suppression of very difficult weeds such as Nutsedge, bermudagrass and Johnsongrass.
  • Works especially well for new citrus plantings.
  • Group 12 herbicide with a unique mode of action inhibiting carotenoid biosynthesis. Results include bleached, white and dying weeds that are noncompetitive with the crops.
  • SOLICAM is a good resistance management tool.
  • Longer residual effects minimize the need for burn down sprays, optimizing ROI for the grower.
  • Reliable performance in all weather conditions. 
  • Excellent compatibility with a majority of tank mix partners, especially with newer chemistries that may have trouble controlling specific grass species.

Use Guidelines

  • Treat prior to weed germination.
  • The soil should be settled, firm and relatively free of weeds and debris at the time of application.
  • Application rate is dependent on soil texture.
  • Sequential applications can be made. Do not exceed maximum recommended rate in the Maximum SOLICAM DF Rates table on the below or in the specimen label.
  • Mix with paraquat, glufosinate or glyphosate to enhance the control of emerged weeds and grasses.
  • Pre-Harvest Interval (PHI) = 30 days
  • Restricted Entry Interval (REI) = 12 hours

Use Restrictions and Precautions

  • SOLICAM DF should be applied prior to weed seed germination and when rainfall or irrigation is likely to occur within 4 weeks of treatment.
  • SOLICAM DF will not control emerged weeds.
  • SOLICAM DF applications on citrus can be made by ground equipment or through irrigation system / chemigation.
  • Do not apply to erodible soil which may wash into the root zone of sensitive plants and do not apply in greenhouses, as crop injury may occur.
  • An application of SOLICAM DF at the label rate may result in temporary bleaching or chlorosis of the leaves from which the trees will recover.
  • Do not apply in areas with poor drainage.

Restrictions and Precautions

  1. In Florida and Texas, sequential applications of up to 5 pounds of SOLICAM DF per acre may be made during a 4-month period. Do not exceed 10 pounds per acre for each 12-month period. In Florida citrus, a single 10-pounds per acre drench application may be used.
  2. Do not apply to germinating seedbeds in which citrus seed has or will be planted or where citrus in interplanted with palm trees. See instructions below for ring drench application directions.

Citrus: Ring Drench Application (Florida Citrus Only)
SOLICAM DF can be applied to newly planted (nonbearing) citrus as a ring drench treatment in the state of Florida. Refer to label for additional details.
