Exploring options for wound protection to prevent Psa-V infection of cut stems Bruno seedlings

Wound protection continues to be a challenge for kiwifruit growers since the incursion of a virulent strain of Pseudomonas syringae pv. actinidiae (Psa) in New Zealand in November 2010. When several products were tested in the field as wound protectants against natural infection by Psa, there were no significant differences between treatments (Miller et al. 2012). Therefore, there is demand in the kiwifruit sector for a wound protectant suitable for pruning wounds. This project evaluates a range of registered treatments not previously tested for protecting pruning wounds against Psa and explores the use of a penetrant for driving the product into the wound to provide protection in the case of bacteria entering the plant during the cutting process.
