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 […]

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 WorkBeneficial nematodes, also known as entomopathogenic nematodes or insect-parasitic nematodes, are microscopic, un-segmented roundworms. They are naturally occurring and already […]

How To Avoid Whiteflies In 2012
What steps should greenhouse growers take to build a successful whitefly management program? SAF weighs in with these suggestions: 1. Scout weekly! Use sticky cards to monitor adults, and check the undersides of leaves to monitor the immature population. Visual inspections, sticky cards and product performance-scouting are all necessary. Don’t let the whiteflies get ahead of you, or your treatment options will be more limited. Don’t wait until shipment to find out you have whiteflies! 2. Do not rely on just one or two effective products. Rotate, rotate and rotate some more with different modes of action to decrease the potential for developing resistance. A resistant B-biotype can be just as bad as a Q-biotype! Or, if you are using a product that only kills the B-biotypes and have a mixed population, you will end up with more Q-biotypes, which are harder to control. Growers should also time product applications […]
