California Spring Trials 2013: Armitage Says It’s Time To Get Serious About Biocontrols
Allan Armitage says it’s time for growers to stop finding reasons why biocontrols won’t work in their operations and take steps to incorporate more sustainable products and methods into their overall crop protection programs.

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, […]

Greenhouse Pest 101: Western Flower Thrips
Western flower thrips (Frankliniella occidentalis) are one of the most, if not the most, serious pests of greenhouse floricultural crops. Although the insects’ actual feeding causes damage to leaves and flowers, the most serious consequence of an infestation is that thrips can spead the tomato spotted wilt virus (TSWV) and impatiens necrotic spot virus (INSV). Both of these viruses are serious problems for a greenhouse grower and can cause large-scale losses of plants. Western flower thrips (WTF) feed on most major greenhouse ornamentals, including chrysanthemum, gerbera, fuchsia, petunia, impatiens and roses, as well as hundreds of other plants species. There are six stages in the thrips’ lifecycle: eggs, which are deposited within the leaves, flowers or bracts, two larval stages, prepupae, pupae and adult. The second-stage larvae are quite active, jumping and crawling on the surface of the leaves. Monitoring For Thrips Monitoring for WTF is essential. By the time […]

Biological Controls And Pesticides Can Work Together
Some growers are interested in combining natural enemies — biological control agents, such as parasitoids and predators — with pesticides, which in this case include insecticides and miticides. The goal is to regulate arthropod (insect and mite) pest populations and avoid or minimize plant damage. Combining the two methods may also lead to a reduction in pesticide applications and, thus, fewer problems associated with pesticide resistance. It is important to understand, however, that some pesticides may have direct or indirect effects on natural enemies after exposure. Pesticides And Natural Enemies The impact of pesticides is not solely based on direct effects like mortality. It is also not uniquely based on contact exposure or odors that influence behavior, which affect the ability of natural enemies to locate prey (hosts) on plants. Pesticides may have indirect effects, sometimes referred to as sub-lethal or chronic effects. These effects consist of inhibiting host foraging […]
