Commercial Foliage and Woody Ornamental Arthropod Pest Management ¹

Lance S. Osborne, Eileen A. Buss, Catharine M. Mannion and James F. Price²

Pest management on foliage and woody ornamentals requires an integrated approach. Integrated pest management (IPM) involves using a combination of management approaches (e.g., biological, cultural, and chemical) to reduce pest problems below levels of economic and ecological damage. No single pest management method will be completely successful.

Monitoring is an essential aspect of an IPM strategy. Regular scouting (once or twice a week) for pest activity, abundance, and amount of damage caused, is necessary to determine optimal treatment timing. Yellow sticky cards placed near plants will quickly indicate the presence of pests, such as whiteflies, aphids, or thrips. Without monitoring, poorly timed, or regularly-scheduled, treatments may be ineffective at controlling the target pest or kill natural enemies. The mere presence of a pest seldom justifies a widespread pesticide treatment.

Understanding insect and mite biology is important to managing infestations. Immatures (e.g., larvae or nymphs) are often the most damaging stage; however, the adults of some insects may also cause damage. Deciding how to control infestations depends on which insect is causing the damage, its life stage, and where or how it is feeding on or damaging the plant. Chewing insects may be easily controlled by contact insecticides, whereas sucking insects, mites, and thrips may be controlled with either contact or systemic materials.

This publication contains pesticide recommendations that may change at any time, as labels and product registrations change. These recommendations are provided only as a guide, and are not endorsements for the products mentioned, nor is criticism meant for products not mentioned. It remains the pesticide applicator's legal responsibility to read and follow all the label instructions on the container of the specific pesticide being used. The labels that may be accessed through this publication are specimen labels and do not take precedence or supercede the pesticide container in your possession.

Federal and Florida Laws state that all pesticides must be handled and applied in strict accordance with the label and worker protection standards (re-entry times, protective clothing, etc.). For complete information pertaining to worker protection standards, visit the EPA Web site.

Be sure to read and follow all label directions and precautions closely. By clicking on the highlighted pesticides, the reader will be linked to a site that contains the label for that particular material. Some sites also have MSDS sheets available in a PDF format.

Remarks: Unlike other whiteflies, the silverleaf whitefly is very difficult to control. To minimize additional resistance problems, one of the above insecticides should be applied two times per week throughout one life cycle (3 weeks) to control an established infestation. (Does not apply to Marathon granules). Insecticidal soap is also effective; however, phytotoxicity may occur when applied repeatedly. Monitor the population to determine if the particular insecticide being applied is reducing whitefly numbers. Some populations may be resistant to one or more of these insecticides. If the infestation persists, use another compound from the above, following the same schedule. Do not apply tank mixes, (except Tame + orthene) as they may enhance resistance. If low numbers of whiteflies persist, apply one of the above insecticides once per week for 3 weeks, then switch insecticides.Undersides of leaves must be covered thoroughly to achieve satisfactory control. Phytotoxicity of these insecticides has not been extensively evaluated. Plants may be damaged, sometimes severely, with any pesticide. Be sure the pesticide is labeled for your particular crop, and closely follow all label directions.
