Finally, the GGSPro team possesses a deep
understanding of conventional chemistry, biological
products and BCAs. This knowledge is shared with
our customers in the form of bulletins and integrated
pest control plans. For example, Aphidius colemani
is a key BCA for use in preventing aphids in lettuce
crops. However, these parasitoid wasps won’t be
effective at stopping an established aphid problem
on their own. GGSPro works with customers to
determine if an additional BCA, such as Aphidoletes
aphidimyza or lacewing larvae would be effective,
or if a treatment of Fulfill is warranted.
