Some non-chemical approaches include cover crops, mulching, mowing, cultivation and biocontrol. Invertebrate pests can enter and consume truffles leaving unappealing damage that lowers market value. Threats come from native fungivores and there is a looming threat that European pests will eventually impact truffle crops. Host trees are also susceptible to insect damage with the potential to decrease yields or cause tree mortality. This TRAPI webinar will consider managing weed and insect pests…
