  1. Corrected mortality (CM) ± SD (standard deviation) for L3–L4 larvae of Lobesia botrana caused by Metarhizium anisopliae strain CEP591 at field conditions. All trials were performed in vivo (Vitis vinifera L. cv. Merlot) on an experimental field located in San Juan (Argentina) (31° 58′ 58″ S; 68° 26′ 28″ W). The trial was initiated at early spring (S1) and repeated at early summer (S2) and late summer (S3), comprising a complete vine productive season. Letter’s a, b indicates significant differences between seasons (Fisher’s LSD; p < 0.05)
