Along those lines, our favorite pest-control tip of the month is the following tip from Growing & Marketing Ginseng, Goldenseal & Other Woodland Medicinals by Persons and Davis:
It is said that a decoction of the entire may apple plant is a good defense against potato bugs. Mash up then boil may apple plants in water. Spread this mixture around your potato plants to deter the pests. It is also said that parts of the may apple plant are poisonous to people. Please use caution, let us know if you try this, and tell us if it works!
