Insect and Mite Management Suggestions for Commercial Poinsettia Production 1
James F. Price, Curtis Nagle and Elzie McCord, Jr.2The vibrant red, pink, white or variegated poinsettia is synonymous with Christmas, and greenhouse, shade house and open field nurseries produce them to coincide with the Thanksgiving to Christmas holiday season. Consumers enjoy poinsettias as hanging baskets, 4 to 8-inch pots and as chest high, single-stem trees, although multiple stem plants in 6-inch pots account for greatest sales. Regardless of growth type, poinsettias add seasonal essence to homes, shopping malls, churches and businesses.
Forty-two major farms produced 4.5 million pots of poinsettias in Florida during 2001 valued at $13.3 million. These were sold in the southeastern U.S.
Important arthropod pests include silverleaf whitefly, fungus gnats, and several others throughout the state. The poinsettia hornworm, or ello moth, is notably important in south Florida.
The Tables in this document list chemicals that are presently available to commercial poinsettia producers in Florida and are organized alphabetically by the following major pest groups:
For each pest presented, products available for control are grouped by active ingredient. Beneficial nematodes and microbial insecticides, components of biological control, are included also. Usually only one example of each formulation is given; however, there may be other products as effective as those listed. Notes taken from labels are provided to qualify some uses.
- Armyworms (see also Caterpillars)
- Caterpillars (see also Armyworms and Poinsettia Hornworm)
- Fungus Gnats
- Mealybugs
- Poinsettia Hornworm (see also Caterpillars)
- Scales
- Shore Flies
- Slugs & Snails
- Spider Mites
- Thrips
- Whiteflies
Precautionary statements, re-entry intervals, restricted use status, and registrants are available in a separate publication, Insecticides, Miticides & Molluscicides Available to Florida's Floricultural Industry (ENY-679) (http://edis.ifas.ufl.edu/IN472 ), to aid in the selection and safe use of appropriate pesticides. When available, hyperlinks to labels are provided in the electronic form. Hyperlinks are to business Web sites and not to any source maintained by the University of Florida and may change without notice.
Many pesticides decompose in the spray tank when mixed with water above pH 7. Growers should test the pH of their water and, when above 7, should add a buffering solution to maintain pH in the 6.5 to 7 range.
This summary is only a guide to aid in selection of pesticides. Care has been given to provide accurate and up-to-date information, but it is possible that through label changes, errors, etc., improper uses may be indicated. In all cases it is the responsibility of the applicator to read, understand, and comply with the label that accompanies each pesticide container.
As an additional precaution, keep the telephone number and address of the nearest county poison control center in a convenient location in case of an accidental poisoning. Also, keep clean copies of labels of all pesticides that are on the premises. In the event of a poisoning, the label of the pesticide involved should be taken to the poison control center or hospital.
