Isonet® L TT and Isonet® L TT BIO, new mating disruption products for the control of Lobesia botrana (Lepidoptera Tortricidae)

Two new mating disruption (MD) products, Isonet® L TT and Isonet® L TT BIO, for the control of Lobesia botrana in vineyards were developed by Shin-Etsu Chemical Co. and CBC (Europe) S.r.l. Both products consist of two parallel capillary tubes (twin tubes) filled with L. botrana synthetic pheromone, and joined and sealed at the ends. Thanks to the gap in the middle, twin tube dispensers are applied easier and faster than conventional single tube dispensers, such as the reference product Isonet® L. The trials carried out in Tuscany (Italy) in 2014 and 2015 on two different grapevine varieties evidenced that both new products are valuable tools for L. botrana control. In fact, efficacy values were always comparable to those of the reference product Isonet® L
