Controlling Weeds Using Biological
SELECTING SUITABLE BIOLOGICAL CONTROL AGENTS
|Selection of a suitable biological control agent begins where the
noxious weed originates. After careful consideration of potential
agents, one species is selected, collected and rigorously screened by
I.I.B.C. to ensure that it will harm only the target weed. Any selected
agent that attacks non-target plant species native to North America or
crops of economic importance is rejected.
Sphenoptera jugoslavica (shown in its larval and adult stages) is used to control diffuse knapweed. It originates in eastern Europe.
