To look at Serenade Prime as product to increase marketable potatoes and uniformity in tuber size through two applications during the growing season.
In the field the ability for the QST713 strain to colonise the root zone and improve the active interface between the soil, plant roots, bacteria and some of the exudate biochemical has been widely recorded. This delivers benefits across a wide range of crops (in WA benefits have been recorded in avocado, citrus, potato and leafy greens trials to date) with increases in nutrient levels in leaves and fruit to assist quality and shelf life among the improvements recorded. The application timing of the product is vital across crop type in order to achieve effective root colonisation. Generally timing should coincide with root flush timings for the respective crop but will also be influenced by the following factors:
Crop type and season length
Application method
Irrigation frequency and volume
Pests to be targeted
As a crop health product in horticulture, more research must be done and as grower experience increases with the product we will find out its BMP and how to best apply within different systems to get the optimum results.
Benefits to look for in potatoes are:
Yield consistency
Tuber size and grade %
Skin finish
Shelf life
The defining element that governs $ROI/ha in the trial is the pack shed pricing for various potato grades. This will fluctuate as will the demand for various grades which can see some of the results above skewing the $ROI. An example is a higher price for gourmet, chats and plain grade in 2016 due to shortages on the east coast which would cause the lower three grades to lose money in the trial as compared to the treated but overall the GM would still be positive.

Plant Breeders’ Rights (PBR)
Some crop varieties used in research trials may be covered by Plant Breeders' Rights (PBR). Users should confirm PBR status of relevant varieties by searching the IP Australia PBR database, http://pericles.ipaustralia.gov.au/pbr_db/ or Variety Central (http://varietycentral.com.au/) and contacting variety owners for further information if required. Where possible, varieties have been listed according to their registered PBR name, although OFT cannot and does not guarantee that the information is accurate or complete.
