How To Manage Mealybugs In The Greenhouse
A mealybug outbreak can be very frustrating for growers because managing these pests is very difficult. Mealybugs are nearly impervious to most insecticides because they have a protective wax covering. Adult females, egg sacs (ovisacs) and some species of older nymphs have this waxy covering. Read more about the challenges of dealing with mealybugs and control and insecticide management advice in this Tech Tip from Syngenta Flowers.

Greenhouse Pests 101: Whitefly
Whiteflies are one of the most easily identified of all greenhouse insect pests. True to their name, whiteflies are tiny (about .06 inches long) whitish insects with four white wings. There are several species of whiteflies, collectively infesting more than 250 ornamental plants. Favorite hosts include lantana, poinsettia, nicotiana, tomato, bean, hibiscus, eggplant and geranium. Whiteflies cause damage by sucking sap from the leaves of plants. Heavily infested plants will weaken and leaves will turn yellow and drop. Whiteflies, like other insects that feed on sap, excrete a sugary substance called honeydew, which is quite sticky. Black sooty mold grows on the honeydew and further discolors the leaves. Eggs, nymphs and adults can be easily seen on the undersides of the leaves. Adults will fly up quickly if the leaves are brushed. Because of this, even a low-level infestation, while not immediately harmful to the plant, will turn off customers. […]

Cool-Season Insect Control
AS growers ramp up production in late winter and into the early spring, they are often caught off-guard when they discover insects or mites feeding on the crops very early in the growing cycle. It can be very frustrating for growers to have to deal with insect pests this early in the season. Although the amount of insect activity and crop injury is usually minimal this time of the year (particularly when the production temperatures are low), if undetected, the populations of these pests can gradually increase and lead to significant crop injury later in the production cycle as temperatures rise. The presence of insects and mites in the early spring occurs frequently with perennials and woody ornamentals that have been overwintered, but they commonly occur in other crops under cool growing conditions, as well. In some instances, there are dormant life stages and eggs that overwinter on plant debris, […]
