Eutypa lata is a significant grapevine pathogen with limited means of prevention and control. The biological control agent Fusarium lateritium can prevent E. lata infection if applied directly onto a vine pruning wound. F. lateritium was suspended and stored in an invert emulsion formulation. A commercially available pruning shear was modified to dispense the formulated F. lateritium onto the cutting blade for direct application onto the pruning wound simultaneously with grapevine cutting. The modified pruner was tested for its ability to cover grapevine pruning wounds using the emulsion formulation. Efficacy of formulated F. lateritium on pruned grapevine canes was also studied using the pruner for application. Addition of grooves in the pruning blade significantly improved wound coverage. Biological efficacy testing determined that applying formulated F. lateritium with the modified pruner was as effective as pipetting formulation directly onto the pruning wound.
