ORCHARD SPRAY APPLICATIONS AND TREE PHENOLOGY ON DEPOSITION OF APPLE TREES

2012 FORELLE FEMA PROGRAMME FEEDBACK

 

Van Zyl, S.A., 2018, ‘Impact of selected orchard spray application technologies and tree phenology on deposition properties on the leaf and fruit surfaces of apple trees’, SA Fruit Journal, Dec – Jan, 74 – 79.

 

Growers invest large sums of money spraying crop management products to achieve optimal fruit yields and quality. Nevertheless, from time to time, plant pests and diseases can cause considerable economic loss. Sub-optimal spraying of products, especially under conditions of high infestation or infection pressure, can result in control failure. Consequently, a better understanding of spray deposition dynamics can assist growers to optimally manage this vitally important fruit farming function.
