Managing weeds can be a challenge in truffle orchards while insects and other invertebrate pests are a significant threat to truffle quality and yields. Weeds in many orchard systems are effectively controlled at low cost using herbicides, but there are potential risks that residues will affect truffle quality and quality, so many growers prefer non-chemical practices. 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…

Successful production of truffles requires critical information on optimal soil and climate conditions.  These conditions dictate where truffles should be introduced, and the amendments needed to assure adequate yields. In this TRAPI webinar we discuss the optimal conditions for both European truffles and native North American truffles.  Irrigation is a critical amendment to achieve optimal soil moisture and to extend yield potential into arid environments.  We review what little is known about moisture requirements and discuss well-tested methods used to schedule irrigation to achieve target moisture conditions.
