High inoculum levels in Psa-affected flower buds
27 November 2014

Samples of infected Hayward flower buds taken from a site with extensive leaf-spotting and flower-bud browning were tested and showed Psa-V levels of 3.3 x10⁷ on the surface of the flower buds.

This inoculum level is very high and similar to levels used experimentally to inoculate in potted plant trials. The result illustrates potential levels of inoculum in canopies with severe leaf-spotting and the value of effective spray programmes.

Trials continue this season to identify spray programmes that provide efficacy in minimising Psa-V infection through spring. These provide evidence of the value for growers of maintaining a proactive programme to protect vines from leaf and bud infection.

A short video demonstrating the effectiveness of spray applications in Psa-V management compares the health of vines sprayed and unsprayed rows and is available on the ZESPRI Canopy here.

As leaf spot can continue to be an inoculum source, with the edges of spots producing inoculum when high-risk weather conditions favour Psa-V multiplication, continuation of copper spray programmes beyond fruit set are recommended . Copper should be applied at summer rates in response to high-risk weather.  An application is recommended following male pruning to protect wounds. Frequency of sprays can reduce as temperatures increase and moisture levels fall reducing Psa-V infection risk.

The KVH Psa-V Risk Model can be used as a guide for growers in planning timing of orchard activities.

Opotiki region update
27 November 2014

KVH staff visited the Opotiki region this week to discuss how Psa-V was progressing in the region this year. Growers generally commented that although leaf spotting had become more prevalent in the last few weeks, the level of flower-bud infection was thought to be lower than last year on both Hayward and G14 orchards visited.

Overall, orchard managers were pleased with the level of Psa-V control being achieved through the use of comprehensive spray programmes despite wetter and colder spring conditions than in past years.

As with other regions, stressed blocks showed higher levels of Psa-V. One very cold block on tough soil showed around 30% flower-bud drop. This illustrates the effects of environmental impacts on disease expression.

Improved orchard drainage (pictured) was seen as an opportunity to improve general vine health and reduce vine susceptibility to Psa-V.

Ambitious has been widely used in the region as part of protective spray programmes and also as a tool to improve overall leaf health.  Good results were being achieved on many orchards. Excellent male management has also assured good pollen supply from orchards in the region.
