The Plant Industry Bureau's Plant Protection Section works with "regulated" pests and disease-causing organisms such as viruses, bacteria or fungi that the state and/or federal government have taken legal actions to control or eradicate. This involves well-known pests like the gypsy moth and emerald ash borer, which we already have in Wisconsin. It also involves many less well-known insects and diseases that threaten our agricultural crops, nursery industry, or forests. Some have already been detected in Wisconsin; others have not, and we would like to keep it that way.
Here are the main pests we are already dealing with or trying to prevent from entering Wisconsin.
