This project aims to develop recommendations for autumn and post blossom thinning of flowers and fruitlets using plant growth regulator chemicals in plums (Prunus domestica and P. salicina) and potentially other stonefruit (peaches and nectarines).
Hand thinning is one of the largest components of variable costs when producing these crops for fresh fruit consumption.
Chemical thinning of stonefruit directly addresses the two key guiding principles:
Stonefrult exports are rising rapidly due to a combination of increased demand in Asian and middle east markets, a lower Australian dollar and improved market access. Australia's place in these growing markets is by no means assured as we have strong competition from low cost competitor countries.
