Scarring of the rind of citrus fruit can prompt packinghouse operators to downgrade the fruit from fancy to choice or even juice.  If you as the grower can recognize the different types of scars you can differentiate between symptoms that indicate biological (e.g., insect, mite, disease, or snail), mechanical (e.g., equipment, hail, or wind rubbing), or chemical e.g., phytotoxic burn) damage. Once you know the causal agent you can take steps to reduce injury to future crops.

In 2017 citrus producers in the Eastern and Western Cape reported abnormal levels of premature fruit drop in a range of different citrus cultivars. In some orchards fruit drop levels of up to 80% of the total yield were recorded. This report is based on an investigation conducted in May 2017 which considered as many potential contributing factors as possible. It aimed to describe the nature of the fruit drop problem and provide future recommendations.

Africa will be key as it is home to two-thirds of the world’s uncultivated arable land.

The BBC’s Taurai Maduna has been to South Africa’s Western Cape to see how drones and data analytics are set to change the game.

As presisieboerdery vir jou ’n mikpunt is, is Aeroview ’n uitstekende hulpmiddel in jou boerdery.

Aerobotics, ’n tegnologiemaatskappy van Kaapstad, se digitale platform is nou bekostigbaarder en gebruikersvriendeliker as ooit. Die maatskappy is al meer as drie jaar lank gemoeid om dataverwerking vir die landbou bruikbaar te maak.

Mnr. Hein Gerber, sitrusboer van die First Fruit Farms by Simondium naby die Paarl, sê Aeroview, Aerobotics se dataverwerkingsplatform, is die gebruikersvriendelikste platform wat hy nog teëgekom het.

“Vir die boer wat bereid is om moeite te doen en ’n behoefte het om in meer detail presisieboerderypraktyke toe pas, sal hierdie platform gewis van waarde wees.
