Insect and Mite Control For Commercial Ornamental Greenhouses

Transcription

1 E & PP Insect and Mite Control For Commercial Ornamental Greenhouses Frank A. Hale Professor University of Tennessee Extension Insect and mite control in commercial greenhouses is often difficult because the artificial conditions found in most greenhouses create a favorable environment for the rapid development and multiplication of these pests. Monitoring for pests is very important. Much too often, insect and mite populations are overlooked, resulting in the increase in population levels and subsequent damage to ornamentals. Greenhouses should be scouted for insect pests on a regular basis to reduce economic damage. The following table lists suggested materials for use against insects and mites in commercial greenhouses. This table is not exhaustive and the chemicals listed serve only as a guideline. Some chemicals may be phytotoxic to certain varieties of plants. Therefore, read the chemical label for a list of plants susceptible to phytotoxicity. Horticultural oil such as SunSpray Ultra-Fine Spray Oil should not be used more than once per week and should not be used on poinsettias after the bracts start to show color. 1
