Over the last few seasons, SACOA has been conducting research into aphid control with BIOPEST in canola.

While the yield loss from aphids transmitting Beet Western Yellow Virus (BWYV) still causes conjecture, it is generally understood that the earlier aphids come in, the greater the yield loss may be at the end of the season.

BIOPEST® is a highly refined biorational pesticide designed for use as a carrier, fungicide, insecticide and to manage aphid-transmitted viruses such as BWYV.

The following video shows the rapid mortality effect BIOPEST® delivers to aphids.

Mode of Action

As a biorational pesticide, BIOPEST® has two key functions in the management of aphid-borne viruses:

  1. Plant Virus Management
  2. Insecticide

Plant Virus Controller

Stylet-borne plant viruses can be transmitted by the probes of winged aphids in less than 20 seconds after landing on the upper leaf surface of host plants.

BIOPEST® interferes with the virus transmission process preventing the pest from inoculating healthy plants and transmitting the virus from diseased ones.


BIOPEST® effectively manages aphids in two ways

  1. Behaviour modification, primarily by modifying insect feeding and egg laying behaviours
  2. By suffocation (anoxia)
