Measuring Up Kontos
Managing common insect pests successfully usually involves an integration of control tactics aimed at minimizing pest immigration and reproduction in the target crop. Successful pest management also involves maximizing the impact of mortality factors that regulate pest density. When conditions are favorable for insect colonization and development and mortality by weather and natural enemies is low, applications of insecticides may be necessary to minimize crop damage. Whiteflies, mealybugs and leafminers are among the most challenging pests to control. Problems with these pests often start when propagules–usually the less conspicuous and most easily transported life stage of the species–are introduced into the crop. Whitefly, mealybug and leafminer eggs and early instars are very difficult to detect by routine inspection due to their small size and secluded behavior. Once established, populations of these insects can quickly reach unacceptable levels triggering insecticide applications. Fortunately, several new insecticides such as spirotetramat (Kontos) are now […]

4 Pest Control Products
If the rumors are true, there are still insect and mite problems on greenhouse crops. The problems are being caused by the usual suspects–the pest group names have not changed much over the decades (although individual species within groups have varied). There’s just been a periodic reshuffling of the rankings in a kind of whack-a-mole scenario. The current top pest group listing includes aphids, mealybugs, thrips, fungus gnats, whiteflies and spider mites. Also fighting for top rankings are leafminers, caterpillars, shore flies and other mites (i.e. broad mites). As with any ranking of best or worst, you might have another list of top pests depending on what crops are being grown. The reasons why there are a fairly constant group of insects and mites to deal with are already well known (rapid pest reproduction cycle, wide host plant range, growing crops in protected environments, continuous production, etc.). These reasons are […]

Overture Registered For Use In California
Valent Professional Products’ Overture insecticide has been registered in California for use on greenhouse-grown ornamental crops. Overture will provide growers consistent, effective control of thrips and lepidopterous larvae. Overture has a novel mode of action that will help growers in the fight against tough-to-control western flower thrips, the single-most damaging pest in California greenhouse ornamentals. Overture is an excellent resistance management tool and rotation partner for Conserve SC. Overture is also soft on most beneficial insects. Overture works preventively or curatively to kill adult and immature thrips, and it also controls defoliating larvae of many lepidopterous pests. Overture can be used on greenhouse-grown ornamentals, including flowering and foliage crops, groundcovers, shrubs and ornamental trees and non-bearing fruit and nut trees. “The single biggest thing about this registration is it offers California growers a novel mode of action for their resistance management programs,” says Todd Mayhew, regional field development manager for […]
