Managing spray application in the presence of drape nets. By Engela Duvenage. “Drape netting reduces tree canopy penetration. It influences where and how thoroughly sprays are deposited onto leaves, and the amount of chemicals ultimately deposited on the outside and…
The MABO Dosing Model. By Engela Duvenage. Using more effective application methodologies to apply pesticide sprays, such as faster driving speeds, reduced air assistance and lower spray volumes, could potentially save apple producers up to 40% in working costs. Such…
We examine the science behind the numbers. By Anna Mouton. Growers know the dosage rates for chemicals because the numbers are provided with the products. But how do scientists evaluate deposition parameters when they are researching ways to optimise spray…
Why optimal tractor speed matters. By Anna Mouton. South African apple growers are turning to high-density orchards because these promise to increase profits. High-density orchards improve productivity — which we all know improves the bottom line. But is there more…
Expert insights into achieving good deposition. By Anna Mouton. Effective crop protection is conditional on effective spraying. Growers need to apply the appropriate products at strategic times using correct techniques. Sounds straightforward — except spray application turns out to be…
