Adopt Biological Control Agents For Greenhouse Crop Production

Many greenhouse growers no longer rely exclusively on conventional pesticides to control pests. Most have increased their use of mechanical and biological control agent (BCA) methods. While pesticide resistance issues have driven much of this change in management philosophy, many growers are now discovering how well BCAs work and how to easily incorporate them into pest management programs. Many greenhouse growers have found that BCAs can be used to achieve commercially acceptable levels of control. However, a few remaining growers believe that BCAs are not practical to implement. The barriers that impede adoption of BCAs typically include the perception that they are less effective than their conventional pesticide counterparts and require special skills and knowledge for success. Performance barriers often can be addressed by implementing preventative use strategies and by fully adopting principles of integrated pest management (IPM) rather than as a direct replacement to conventional pesticides. Development of pest […]

SePRO Corporation Introduces New Preferal Biological Insecticide

SePRO Corporation announced on January 26, 2012 that it will introduce its new Preferal Biological Insecticide to the United States commercial greenhouse, nursery and landscape markets.  Preferal contains blastospores of a naturally-occurring strain of the fungus Isaria fumosoroseus, which has demonstrated very good control of whitefly, aphid, thrips and spider mites.  Certis USA,has entered into a marketing-and-supply agreement with SePRO to market and further develop Isaria fumosoroseus in the U.S. greenhouse, nursery, landscape and turf markets.  Preferal is being used successfully by European growers today in integrated pest management programs to provide control of all life stages of whitefly.  This insecticide is formulated as a water dispersible granule that is mixed with water and applied as a spray.  Spores of Preferal then attach and penetrate the cuticle of targeted insect pests.  The fungus grows inside the insect, causing its death.  Under favorable environmental conditions, the fungus will emerge from killed […]

Kontos Label Revised

The Kontos insecticide/miticide label was recently revised to help increase product performance. Soil drench application rates have been increased and thrips and scale crawlers have been added to the label. Kontos has unique features that set it apart from most other products such as true up-and-down movement in the plant.  It is both foliar and root absorbed. Kontos is phloem-active, meaning users can spray and be assured the active ingredient, spirotetramat, moves down in the plant. When applied as a foliar spray, a spreader-sticker may improve performance. Growers can also soil drench Kontos. Because it is xylem-active, the active ingredient will move up systemically through the roots to the growing tips. Soil drench rates have been increased to offer better control of hard-to-control insect pests. “The best way to use Kontos is early in the crop cycle when insect populations are low and the product has time to work,” says […]

Total Release Pesticide Application Saves Growers Time And Labor

Modern total release (TR) technology – commonly known as aerosol foggers – is rooted in convenience. Nearly 70 years ago, when the U.S. government sought a more convenient way to spray malaria-carrying insects, researchers developed a compact aerosol can pressurized by gas. While that invention has evolved dramatically since, its user benefits, including ease of use, accurate application and time and labor savings, continue in today’s technology. Total release pesticide delivery for greenhouses was brought to market in 1978 by Whitmire Micro-Gen, which licensed active ingredients from other manufacturers to develop TR products. These first-generation TR products required canisters the size of 20-pound propane tanks. Current TR micro-pro technology-based products, such as those from BASF Professional Turf & Ornamentals, contain less propellant and broader-spectrum, more efficacious active ingredients. As a result, a 2-ounce and 6-ounce TR canister can now treat up to 3,000 and 4,500 square feet of greenhouse, respectively. […]

Biopesticides: Are They Immune To Resistance?

Pesticides used in horticultural cropping systems are generally divided into two categories: conventional and selective (alternative). However, it is often difficult to distinguish between the two categories because, depending on your perspective and bias, a selective pesticide may be considered conventional, and vice versa. Conventional pesticides generally are those that typically belong, although they’re not limited to, the chemical classes organophosphate, carbamate, pyrethroid and neonicotinoid. But what really is a conventional pesticide, and how can it be distinguished or differ from a selective pesticide? Additionally, what about terms like “biopesticide,” “biorational” and “reduced-risk pesticide.” Sometimes, these, as well as selective pesticides, are also referred to as “soft” pesticides. All of these terms, particularly “biopesticide,” have been used to separate certain insecticides from the more conventional types. So what are biopesticides? They are pest control materials that are placed into several distinct classes: The Classes 1. Microbial pesticides (or myco-insecticides). This […]

Biopesticide Resistance And Selective Pesticides

Insects Resistant To Biopesticides There are many instances in which insect pest populations have developed resistance to selective (alternative) pesticides or biopesticides. Here are several examples: • Green peach aphid (Myzus persicae) resistant to azadirachtin (e.g., Azatin) • Western flower thrips (Frankliniella occidentalis) resistant to spinosad (e.g., Conserve) • Leafminer (Liromyza trifolii) resistant to both spinosad (e.g., Conserve) and abamectin (e.g., Avid) • Greenhouse whitefly (Trialeurodes vaporariorum) resistant to buprofezin (e.g., Talus) • Sweet potato whitefly B-biotype (Bemisia tabaci) resistant to pyriproxyfen (e.g., Distance) • Diamondback moth (Plutella xylostella) resistant to Bacillus thuringiensis spp. kurstaki (Dipel) Selective Pesticides Categories of pesticides (insecticides and miticides) used in greenhouses or nurseries that may be considered as either selective (alternative) pesticides or biopesticides, including the common name (=active ingredient) and trade name (in parentheses): Insect Growth Regulators • Azadirachtin (Azatin, Ornazin, Molt-X and Azatrol) • Buprofezin (Talus) • Cyromazine (Citation) • Diflubenzuron (Adept) […]

Beneficial Nematodes: Exploring Their Role & Value

While great strides have been made in the development of effective beneficial nematodes over the past several years, there is still confusion among growers about these little worms. Are they safe? How do they work? Do they cause damage? To help clear things up, we have put together a three-part series all about beneficial nematodes. With a variety of factors drive pest management changes in horticultural operations, many professionals are looking to expand their use of biological control agents (BCAs), including their use of beneficial nematodes. Growers find beneficial nematodes to be an attractive addition to existing pest management programs because they reduce or eliminate restricted-entry intervals, have limited impact to worker and customer safety, promote environmental stewardship and are valuable pesticide resistance and residue management tools. How Beneficial Nematodes Work Beneficial nematodes, also known as entomopathogenic nematodes or insect-parasitic nematodes, are microscopic, un-segmented roundworms. They are naturally occurring and […]
