Wine grapes: Bud break carbohydrates rule the roost
Wilmé Brown (Plant Physiologist) and Dr. Elmi Lötze (Head of ITEST™CARBOHYDRATES, ITEST™LEAF and Research and Development) Carbohydrates and viticulture The vine needs carbohydrates to survive the winter (the time during which leaves are absent and active photosynthesis cannot occur) and also to support vegetative growth during the coming season until new leaves emerge. While […]
Small grain leaf analyses tell a story
Nicola Kotzé, Senior Agronomist Dr. Elmi Lötze, Head of ITEST™CARBOHYDRATES and ITEST™LEAF Leaf analyses speak volumes Leaf analyses on small grains can identify mineral deficiencies even before visually observed, allowing farmers/growers to address deficiencies at an early stage, thus saving costs. Leaf analyses are generally used with great success in permanent crops, as well […]

The crucial role of formulation in the efficacy of nutrient foliar products by Rochelle Thuynsma, Head of Products: Technical and Dr. Elmi Lötze, Head of ITEST™CARBOHYDRATES and ITEST™LEAF Introduction Foliar-applied fertilisers have become an integral and significant part of sustainable and productive crop management worldwide. Successful application of nutrients in permanent crops has been reported […]
The role of carbohydrates in alternate bearing in pecans
The role of carbohydrates in alternate bearing in pecans by Dr Elmi Lötze (Head of ITEST™CARBOHYDRATES and ITEST™LEAF) and Deon Claassen (Senior Horticulturist) Alternate bearing Carbohydrates play an important role in the alternate bearing cycle of many fruit types, including pecan trees. Alternate bearing refers to the phenomenon where trees produce a large crop in […]
The critical role of MAJESTIC™ during fruit production
The critical role of MAJESTIC™ during fruit production By Rochelle Thuynsma, Head of Products: Technical Introduction In fruit crops, flowering time and intensity depend on the species, tree age and the prevailing climatic conditions.(1) Flower induction is the first phase of floral meristem growth and determines final flower intensity and ultimately, fruit set and yield.
