Gowan Launches Improved Biopesticide Formulation

Gowan Company has launched an improved formulation of Aza-Direct biopesticide. Aza-Direct contains the active ingredient azadiractin, which is extracted from the seed of the neem tree. Azadiractin-based products are susceptible to degradation once formulated and packaged. The result is a time-sensitive burden for growers to use these products. Gowan Company chemists seized the opportunity and set out to develop a superior product by means of stabilizing and improving the formulation. The project started with Gowan formulation chemists identifying the root cause of degradation and replacing the infringing components with more stable components. With the new components in place, the improved formulation proved to be highly superior in all field performance trials. “Aza-Direct is a wonderful tool for growers because it has a favorable label, is soft on beneficial insects and is certified organic so it fits well into conventional and organic production,” says Chad Dyer, product manager for Gowan Company.

Molt-X Insecticide/Nematicide Now OMRI Listed

BioWorks‘ EPA-registered Molt-X botanical insecticide/nematicide is now listed by the Organic Materials Review Institute (OMRI) for use in organic production. Molt-X works primarily as an Insect Growth Regulator (IGR) 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. Molt-X is an emulsifiable concentrate containing 3 percent azadirachtin. While it is derived from neem seed, Molt-X is not a neem oil. It has a four-hour Restricted Entry Interval, zero-day pre-harvest interval and is labeled for use on a broad range of turfgrass, outdoor shrubs, trees ornamentals and food crops, as well as on greenhouse ornamentals and crops produced in shadehouses and nurseries. Other key product features of Molt-X are […]

Perspective: Terry Higgins, Vice President & General Manager, OHP

If people think it’s difficult to live in a world with pesticides, they should try living in a world without them. OHP’s Terry Higgins admits he wasn’t the first person to speak those words. But having spent 35 years in crop protection, Higgins is a big believer in that message and the need for pesticides. “Sometimes, I wish we as an industry could pull all of our products off the marketplace,” Higgins says, “because I can guarantee you in two years, people would be begging and clamoring for us to bring them back.” Some things, such as the pressures crop protection providers and their users face, never change. But crop protection as a whole is continuously evolving, and Higgins, because of his experience, has a unique perspective on the industry’s development. Recently, we caught up with Higgins to get his perspective on the developing market of generic crop protection products, […]

Pesticide Resistance In Natural Enemies

Pesticide resistance is always a concern because once an arthropod (insect or mite) pest population can no longer be adequately suppressed with existing pesticides, then management options become limited. Resistance is the genetic ability of some individuals in an arthropod pest population to survive an application or multiple applications of a pesticide. In other words, the pesticide no longer effectively kills a sufficient number of individuals in the arthropod pest population. Resistance develops at the population level and is an inherited trait. As such, surviving arthropod pests can pass traits genetically onto their offspring or next generation, enriching the gene pool with resistant genes (alleles). The amount of “selection pressure,” or the frequency of applying pesticides, is the main factor that influences the ability of an arthropod pest population to develop resistance to pesticides. This then increases the proportion or frequency of resistant individuals. However, there are sometimes inquires or […]

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 […]
