Kiwifruit Bacterial Canker (KBC)

Comparison between area heavily affected by kiwifruit bacterial canker and neighbouring area* treated with BioAksxter® (Bigo Mauro farm, Verzuolo - CN).

* The plot, called “Sabbioni”, has been treated with BioAksxter® since April 2009. The surface area is 1.2 hectares planted with kiwi fruit of the Hayward variety about 20 years old. The plot is located in Falicetto di Verzuolo (CN), one of the areas of the province most affected by the bacterial disease.

14 May 2010 | Border crops NOT treated with BioAksxter® M31

The first symptoms of kiwi bacteriosis appear. The disease, present in several places in the area, manifests itself as leaf necrosis surrounded by discoloured areas. The affected plants show branches with withered leaves and shoots and browning of the inflorescences.

14 May 2010 | Plot TREATED with BioAksxter® M31

Only a few spots on the leaves are noticeable. Neither shoot desiccation nor browning of the flowers can be observed. 

18 March 2011 | Untreated neighbouring crops

The characteristic reddish exudate emerges from 30% of the plants in several places.

18 March 2011 | Plot TREATED with BioAksxter® M31

Exudate escape affects 10% of the plants. In contrast to untreated crops, exudate escape is lower.

13 May 2011 | Untreated neighbouring crops

90% of the plants were strongly affected on most shoots. The crops were uprooted.

13 May 2011 | Plot TREATED with BioAksxter® M31

Throughout the plot the disease is stationary. In the part least affected by the disease there are no affected plants, while in the part bordering the grubbed-up crops 30% of the plants show symptoms on half of the branches.

14 July 2011 | Other neighbouring crops NOT treated and not yet eradicated

The disease continues to spread in the fruit-growing area and new outbreaks occur. Plants that have now been pruned show symptoms of the disease again on new shoots.

14 July 2011 | Plot TREATED with BioAksxter® M31

The disease is contained, and no new infections are evident. The affected plants show considerable vegetative activity and the shoots of the branches that have been cut show no symptoms.

09 September 2011 | Other untreated neighbouring crops close to grubbing-up

In the other untreated neighbouring crops, the disease caused a heavy yield loss.

09 September 2011 | Plot TREATED with BioAksxter® M31

No new infections are recorded. The shoots of the previously affected and cut plants show no symptoms of the disease; the fruits develop with regular shape and size.

Plants unaffected by the disease have unprecedented growth, development and production.

Although some of the plants are producing less due to the removal of branches, the estimated total production is 260 quintals per hectare, which is equal to the average of other years.

Even in all the other plots on the farm, where the disease did not occur or only affected a negligible percentage of plants, a significant increase in production was observed following treatments with BioAksxter® M31.

The estimated total production is at least 30% higher than the average of other years.
