8/9/20 - In Riwaka, with 100 hectares of export pipfruit, Cederman Brothers’ orchard manager Nathan Binns and apprentice Tyler Cederman appreciate tools that enhance management. Approaching their fourth season using ADAMA NZ thinner Brevis, Nathan and Tyler also used the Brevis companion web-based prediction tool BreviSmart for the 2019/2020 season with the help of their Fruition consultant Greg Dryden.
Brevis is a photosynthesis-inhibiting fruitlet thinner, which mimics shading. It is applied when fruitlets are about 8-14 mm in size, does not require the addition of surfactants and is rain-fast within two to three hours. Block re-entry is possible after three days, minimising disruption. Brevis also has an excellent fit with IPM programmes.
Determining the best timing with BreviSmart
BreviSmart helps determine the best timing for Brevis applications, factoring in solar radiation, temperature, fruitlet size and variety. Developed in conjunction with IBM, BreviSmart uses weather data and forecasts from The Weather Company, an IBM business. The Weather Company delivers one of the most accurate weather forecasts, utilising an extensive network of weather stations globally and locally.
Actual weather data from weather stations closest to the orchard from
5 days before the calculation and the forecasted weather for 5 days
after (incl. the calculation day) are used in calculations. In
addition, growers will consider block history, vigour, cultural
techniques, and spraying conditions.
