Facts About Major Greenhouse Pests

A Kansas State University entomologist has published a series of fact sheets on management of major insect pests in greenhouses and nurseries. Written by Raymond Cloyd, a specialist in ornamental entomology and integrated pest management, these two- to eight-page publications cover biology and damage, scouting, cultural and physical management, insecticidal and biological control of common pests. They also provide insight into the importance of dealing with pests holistically instead of solely relying on insecticides. Fungus Gnats Major insect pests in greenhouses and nurseries, they are one of the few insect pests in which the damaging life stage, the larva in this case, is located within the growing medium. (MF-2937) Broad and Cyclamen Mites These mites feed on plants in more than 60 plant families, including houseplants, flowers, strawberries and vegetables. (MF-2938) Bulb Mites Bulb mites feed on plants in the lily family, such as amaryllis, crocus, freesia, gladiolus, hyacinth, lily, […]

Pesticide Free Certification To Include Ornamental Plants

Scientific Certification Systems (SCS) has expanded of its Lab Tested and Certified Pesticide Free program to include ornamental plants. Historically, the certification has helped vegetable and fruit growers offer their customers products that meet the highest levels of safety. The expansion of this certification allows horticultural producers to assure their customers that their flowering and ornamental plants are of the highest quality and safe for their homes and gardens. The Pesticide Free Certification provides the same measure of safety consumers receive when they purchase certified fruits and vegetables. Growers can use certification to demonstrate to retailers that they meet increasingly stringent safety requirements. “We conduct pesticide testing that exceeds government requirements so our clients have the highest confidence in assuring retailers that their products are safe,” says Wil Sumner, director of agricultural testing & certification at SCS.

Pest Confirmed As Present In 13 States

In May, the Canadian Food Inspection Agency (CFIA) notified the Animal and Plant Health Inspection Service (APHIS) about an interception of Duponchelia fovealis larvae in a nursery shipment from San Diego County, Calif. Since then, APHIS and State Departments of Agriculture have confirmed the presence of Duponchelia fovealis in 13 states, including Alabama, Arizona, California, Colorado, Florida, Georgia, Mississippi, North Carolina, Oklahoma, Oregon, South Carolina, Texas, and Washington. Duponchelia fovealis originated in southern Europe and North Africa and can be found in the environment. It is, however, considered a greenhouse pest. The moth’s dispersion is natural, and it is not very cold tolerant. Duponchelia fovealis has a wide range of host plants, including peppers, pomegranates, aquatic plants, bedding plants and nursery stock. APHIS, in partnership with the affected states, plans to examine the regulatory status, options, and next steps, including federally recognized state managed phytosanitary options such as official control […]

SePRO Insecticide Targets Western Flower Thrips

SePRO Corporation’s new Hachi-Hachi insecticide has been approved by the U.S. EPA for use in the U.S. commercial ornamental greenhouse market. Hachi-Hachi contains the active ingredient tolfenpyrad, which is a new broad-spectrum insecticide with a unique mode of action against target insect pests, specifically Western flower thrips. Research trials with Hachi-Hachi have demonstrated excellent control of thrips, aphid, scale, whitefly, leafhopper and lepidopteron insects. Hachi-Hachi is active on all life stages of most targeted insects. In addition, Hachi-Hachi has shown ovicidal and anti-feeding activity on these target insects. “SePRO and IR-4 research efforts with Hachi-Hachi have been ongoing since 2006 in the U.S. ornamental greenhouse market,” says Todd Bunnell, SePRO’s turf and ornamental research manager. “Results have proven Hachi-Hachi to be a very promising tool for growers due to its unique mode of action and by demonstrating no cross-resistance with existing insecticides.” Adds Roger Storey, SePRO’s vice president of the […]

New Grant to Support IPM In Pennsylvania

The Pennsylvania IPM program recently received a multi-year grant to continue its mission to reduce pesticide use in agricultural and urban settings. The grant, awarded by the U.S. Department of Agriculture, National Institutes for Food and Agriculture (USDA/NIFA), will help Pennsylvania IPM further its extension and outreach efforts to promote integrated pest management practices that are economical and protect human health and the environment. The program will work in both rural and urban areas to provide technologies, resources and educational opportunities across the state. For specialty crops, PA IPM will continue to build on previous projects. The program will work with high-tunnel vegetable growers in Lancaster County to incorporate beneficial insects to control pests and reduces pesticide use. PA IPM will also work with Amish and Mennonite growers about using an IPM approach to manage pests. The Pennsylvania IPM program is a collaboration between Penn State University and the Pennsylvania […]

Battle Of The Bugs

Interest in alternative pest control strategies seems to come and go based on the efficacy of the products currently available to growers. But when their tried and true formulations stop working, there’s a collective scramble to find out what else can be used to manage pest populations. The Pest & Production Management Conference hosted by the Society of American Florists and Greenhouse Grower in Orlando, Feb. 25-27, was the place to be to get the most current information. Growers also are pursuing alternative methods to help with their sustainable and organic certification initiatives. They want to gain experience with what really works before they abandon or supplement traditional control products. Margins are not forgiving enough for crop failures. Experimenting With Essential Oils Raymond Cloyd and his students at Kansas State University have been testing the efficacy of essential oils derived from plants for pest control. The oils are harvested through […]

A Step Forward For Pesticide Safety Training

The Environmental Protection Agency (EPA), of course, requires all greenhouse operations using pesticides to train workers in their native language about safety. For years, growers have trained their employees by popping in short videos that meet the safety standards. But growers in Virginia are taking pesticide safety training a step further by welcoming a bilingual pesticide trainer from the Telamon Corporation to their operations for more hands-on instruction. “Our service goes a step beyond,” says Nicholas Zetts, the pesticide safety trainer for Telamon. “We offer an informal classroom setting and you have interaction with a trainer–and it’s bilingual. You’re going over information workers understand. They’re also now free to ask questions to the trainer. And it’s a completely free service. “When you’re watching a video, no one is there to assist you.” Zetts’ pesticide safety training sessions range from as short as 45 minutes to as long as two hours.

Molt-X: BioWorks’ New Insecticide

BioWorks has added a botanical insecticide, Molt-X, to its product line. Molt-X was recently EPA approved and it has multiple modes of action to provide broad-spectrum control over pests like aphids, whiteflies, thrips, mealybugs, scales, plant-parasitic nematodes and others.   Molt-X works primarily as an insect growth regulator that disrupts the molting process in insects. Once treated with Molt-X, insects become sluggish, stop feeding and fail to mature and reproduce. Molt-X also acts as an insect repellent, antifeedant and ovipositional deterrent. These multiple modes of action make it a highly effective tool for use in a resistance management program.   Other key features of Molt-X are it: –Leaves no residue on plant foliage and flowers–Has no phytotoxicity issues on most plants–Is generally safe on beneficial insects and bees; and –Is compatible for tank-mixing/rotation with other registered inputs, including BotaniGard and SuffOil-X.  “This is an excellent compliment to our existing products,” […]

Kontos Held Up In Court

SAF is urging growers to contact the Environmental Protection Agency (EPA) before February 8 and ask the agency to allow the continued production and use of Kontos insecticide, pending a new registration. Kontos is manufactured by Bayer Crop Science and distributed by OHP. It’s used to control adelgids, aphids, leafhoppers, mealybugs, psyllids, spider mites, spittlebugs and whiteflies. It was approved for ornamentals in greenhouses, nurseries and interiorscapes by the EPA in August 2008. A recent court order, however, requires re-registration and could prevent use of supplies growers already have on hand. EPA intends to issue a cancellation order for the insecticide as a result of a U.S. District Court decision in December, when the court ruled that the EPA’s failure to provide an opportunity for comment on registration applications vacates the registrations of that chemical. Even though EPA had approved the applications for Kontos, the registration will no longer be […]
