Frost Tactics 2 Trial 3: Nutrition high frost risk locations
Aims

to determine if in season applications of potassium and/or copper can lessen damage caused by frost

to determine if other noval products are able to reduce the damage caused by frost either through reduction in INB or making the plant less susceptible to frost damage 

Key messages

Choosing varieties with a phenology that shifts flowering away from when a frost is likely to occur, can reduce frost damage/risk.

Other trial notes

With very small differences in varietial tolerance to frost, one of the easiest management decisions a grower can make in a frosty area is to plant a variety that will flower outside the tradtional frost window. However there is still need to understand the drivers of phenology with the latest varieties and differing sowing times.
