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.

De Kock, V.A & Buchanan, R., 2010, ‘Optimum harvest maturity and cold storage potential of Sun Supreme TM plums’, SA Fruit Journal 9(5), 36-37.

 

The Sun SupremeTM plum cultivar was bred by the South African Agricultural Research Council – Infruitec-Nietvoorbij and was released to the stone fruit industry in 2005. The skin as well as the flesh colour of the fruit is yellow. Within the current yellow skinned plum cultivar range, Sun Supreme TM ripens between African PrideTM and Songold. It is normally harvested from the middle to the end of January in the Western Cape. An outstanding characteristic of the cultivar is the excellent fruit size, in the range of 55-65mm fruit diameter…

Buchanan, R., Vos, R. & Trout, A., 2011, ‘Optimum maturity and cold-storage potential of the new SAPO TRUST stone fruit varieties Sweet December and Summer Jewel’, SA Fruit Journal (10)3, 42-44.

 

The commercialisation of new fruit varieties for the South African fruit industry is a robust and competitive business, the success of which is highly dependant on an in-depth understanding of variety performance, from the orchard to the consumer. This knowledge, acquired by way of disciplined process, is a necessity when undertaking informed variety investment and cultivar management decisions.

To enable the effective and responsible commercialisation of varieties, the SAPO Trust has appointed ExperiCo (Fruit Technology Solutions) as their ISO 9001:2008 certified service provider. In this capacity ExperiCo conducts storage trials across the SAPO Trust variety range, with the aim of providing comprehensive commercial harvesting, packaging and storage protocols for successful varieties, upon their release to the South African fruit industry.

ExperiCo conducted post-harvest evaluations on the new ARC Infruitec-Nietvoorbij plum varieties Sunbreeze, Lady West and 4A-35-14, on behalf of the Deciduous Fruit Producers’ Trust (DFPT), during the 2003 and 2004 seasons. The varieties were identified and prioritised by the Stone Fruit Operational Committee as having potential for the South African stone fruit industry.

Fourie, J., Taylor, M., Vos, R. & Van Geyt, P., 2005, ‘A modified atmosphere packaging system for the maintenance of table grape quality during cold storage’, SA Fruit Journal 4(3), 24-27.

 

The supply of good quality table grapes is expected, and demanded by the market and consumers (Eckert, 1975). The maintenance of post-harvest quality of fresh fruit is becoming increasingly important as the emphasis shifts to fresh and high quality produce (Thompson, 1998). South Africa, as an exporter and supplier of fresh fruit, is directly involved in the continuing quest for solutions to overcome the problems related to storage and transport of fruit over long distances.

MAP & OTHER TECHNOLOGIES TO DECREASE THE STORAGE PERIOD OF FORELLE PEARS

 

Crouch, I., Bergman, H., Moelich, D. & Van Zyl, S., 2013, ‘Evaluation of modified atmosphere packaging and other technologies to assist in decreasing the 12 week mandatory cold storage period of Forelle pears’, SA Fruit Journal 12(1), 66-69.

 

South Africa has two main bicolour pear cultivars which are exported to Europe – Rosemarie and Forelle. Forelle sold before 12 weeks cold storage may not ripen normally, and are often astringent, mealy – or both. Consequently, Forelle pears are subjected to a mandatory 12 week cold storage period before they can be sold, creating a gap in the supply of bicolour pears to the market. The urgent requirement to maintain this bicolour supply sometimes results in Forelle being harvested too early, resulting in fruit of unacceptable eating quality.
