Effect of Triadimefon on Development of Mycorrhizae from Natural Inoculum in Loblolly Pine Nursery Beds
Abstract:Three or four applications of triadimefon at a rate of 6 oz/ac/application to loblolly pine (Pinus taeda L.) nursery beds in the spring to control fusiform rust did not significantly affect mycorrhizal development from natural inoculum, as determined in the autumn and/or winter; higher rates (12 oz/ac and 24 oz/ac) significantly decreased amounts of mychorrhizal roots. The symbiont Pisolithus tinctorius (Pers.) Coker & Couch was more drastically affected than were other mycorrhizal fungi, based on Pt indices. Use of triadimefon at a 4 x rate (24 oz/ac/application) for three consecutive years yielded no evidence of a buildup in soil. South. J. Appl. For. 11(1):49-52.
