Abstract
  • During 2007 and 2009, aerial spray trials were carried out in order to evaluate the effectiveness of four Bacillus thuringiensis kurstaki (Btk) formulations against gypsy moth infestations in North Sardinian cork oak forests. Based on randomized-blocks, the experimental design involved three replicates on 25-50ha-plots for each of the following thesis: 1. Untreated Control; 2. Foray 48B(S), flowable concentrate formulation used for standard application, containing 12.7 BIU/L; 3. Foray 48B(N), flowable concentrate formulation including new safety ingredients, containing 12.7 BIU/L; 4. Foray 76B, flowable concentrate formulation containing 20 BIU/L; 5. VBC-60074, dry flowable formulation containing 64 BIU/kg. A good efficacy was recorded in trials with Foray 48B(S), Foray 48B(N) and Foray 76B. These formulations caused mortality rates greater than 80% and adequately protected trees from defoliation. The dry flowable formulation, VBC-60074, produced the lowest efficacy probably in relation to a higher evaporation of spray droplets resulting in less overall coverage of target foliage. (literal)
