Phyllis Martin at USDA-ARS, is the first new broad-spectrum microbial insecticide
to enter the market in nearly 50 years.
Targeting larvae is more desirable than controlling adults because the larvae are concentrated in a relatively small area; whatever microbial insecticide
adopted needs to be consumed by mosquito larva and must be applied well before the last larval instar stage (1).
This microbial insecticide
is generally toxic only to leaf-feeding caterpillars; the spray has no effect on adult butterflies and moths.
Next-generation microbial insecticide
raises the bar for modern pest management with broad-spectrum control, complex modes of action, long-lasting performance and application flexibility
Side-effects of the microbial insecticide
PreFeRal WG (Paecilomyces fumosoroseus, strain Apopka 97) on Bombus terrestris.
Research that improved microbial insecticide
formulations also led to environmentally friendly chemical formulations.
The introduction of Grandevo signals the availability of the first new broad-spectrum microbial insecticide
in nearly 50 years and offers growers the ability to employ bioinsecticides in ways never before thought possible.
Other products pending approval include an invasive mussel control product for waterways called Zequanox(TM), a new microbial insecticide
for control of sucking insects and beetle pests, and a new microbial herbicide for controlling weeds in turf, rice, and other grain crops.
PFR-97 is a microbial insecticide
originally developed by scientists at the University of Florida.
PFR-97 microbial insecticide
has been registered by the Federal Environmental Protection Agency (EPA) to control thrips, psyllids, whiteflies, mealybugs and spider mites on fruit and vegetable crops.
Many of the microbial insecticides
