Traps and lures may attract insects by visual or chemical cues. Visual traps, such as yellow, sticky boards, are generally used to monitor insect populations. Lure traps, such as Japanese beetle traps, contain chemical attractants. Electronic and ultraviolet traps are not recommended. Watering in the morning gives plants time to dry during the day.
Drip irrigation prevents the foliage from getting wet.
To prevent fungal infections, leave space between plants for good air flow. Orient rows so winds will help foliage dry quickly after rain or watering. To prevent spreading diseases, stay out of the garden when plants are wet with rain or dew. Revised and updated by Richard A. Ashley, IPM Coordinator, University of Connecticut.
