Prunetec - Invitro study of Psa survival in PruneTec (Wound protectant)

The purpose of this trial was to carry out an invitro study of Psa survival in wound protectant (PruneTec).

Wound protectants are used to protect wounds following pruning and grafting. Kiwifruit vines are pruned to remove excess wood in summer and to structure the vine in winter. Pruning wound dressings generally contain a bactericide that aimed at providing protection from bacterial infections. This report presents the evaluation of PruneTec 20001948 wound protectant tested against Psa-V to determine efficacy under laboratory conditions.

Impact of covered structures on the progression of Psa-V, Phase Two

Trials were set up in the kiwifruit growing season of 2012–13 on three orchards to test whether plastic, breathable covers erected over existing kiwifruit vines could reduce the incidence, progression and severity of Pseudomonas syringae pv actinidiae (Psa-V) infections. These structures had been erected in an attempt to slow the progression of Psa-V. Vines were already infected with Psa-V, with varying levels of symptoms expressed. Across the three sites the varieties Actinidia chinensis ‘Zesy002’ (Gold3), A. chinensis ‘Zesy003’ (Gold9), A. deliciosa ‘Zesh004’ (Green14) and A. chinensis ‘Hort16A’ were assessed, along with Gold3 scions that had been notch grafted onto existing rootstocks. Grafted seedlings were planted out at each site and used as trap plants that would indicate infection from Psa.
