Excellence in cold chain management

Scientific facts in cold chain management
Although a scientific approach of post harvest technology for fruits, vegetables and flowers goes back to the 1970’s, many partners in the logistic chain still lack awareness and knowledge of basic principles. All efforts that the producer has made to reach top quality products may be lost within 24 hours by mismanagement of the cold chain. The small gain made by saving on the cold chain is negligible compared to the loss of value it will cause. Proper cold chain management from farm till buyer is an essential condition for the preservation of the quality and the value of a perishable product.

The respiratory metabolism
Cut flowers, harvested fruits and vegetables are still alive and carry on characteristic processes of all living things. The most important process is the respiratory metabolism. It is a natural process of ripening, senescence and deterioration of the plant. The bio-chemical reaction (for 1 mole): C6H12O6 + 6O2 + 6CO2 + 6H2O + 686 kcal 294 kcal of the produced energy is used for internal processes but 392 kcal is heat. Cut flowers, beans and the vast majority of Kenyan fresh produce are climacteric plants and have a very high respiration rate. The respiration is triggered by ethylene, a self-regulatory hormone produced by the plant itself.

Downy Mildew Management in Roses

Description
Downy mildew is a fungal disease that causes destruction of leaves, stems, and flowers of the infected plant. Downy mildew causal organism is called Peronosporasparsa and as the scientific name indicates, the production of spores is sparse and therefore this disease is difficult to diagnose and control.

  • Downy mildew (Oomycete fungi) are referred to as a high risk pathogens because of the following factors;
  • Oomycetes fungi are able to spread in an explosive manner under favorable conditions.
  • Short development cycle (8-10 days under optimum conditions)
  • High potential for reproduction (high quantities of spores)
  • Wide propagation by water and wind
  • Damage is not reversible: The damaged tissues die in general leading quickly to substantial losses at harvest
  • High genetic variability: Rapid appearance of strains less sensitive to specifically acting fungicides possible.

Selecta One, Wagagai Flower Farm

Initiate New Role Model of Trading Fair Poinsettias

Since 2016, Selecta one supplies Fairtrade certified young plants to their poinsettia growers besides conventional ones. All poinsettias are sourced from Wagagai Ltd. in Uganda. Besides improving health and safety measures, enabling freedom of association and collective bargaining the employees benefit from a Fairtrade Premium, which can be used for social projects. Already in 2016, Selecta generated through their poinsettia sourcing at Wagagai a return of 8,000 Euro to local workers as a premium. Independently from this Selecta and Wagagai are fulfilling all environmental and social standards set by Fairtrade to meet the certification requirements.

In Uganda as well as in other developing countries, basic wages in agriculture are well below what would be considered a living wage. Pay is insufficient to allow workers and their families meet their essential needs and afford them a decent standard of living. The absence of a minimum wage in Uganda compounds the problem. Besides that, wages cannot keep up with the rate of price increase. As a consequence people loose purchasing power. In addition many public services like schools are charged in developing countries. Often people do not have enough cash to send their children to secondary school.
