After leaving the nozzle, a crop protection agent finally reaches the plant, soil or a pest where the product has to do its job. The product must overcome a number of barriers to achieve high effectiveness, with weather-related processes playing an important role. These processes take place a few days before, during and after spraying. The Sprayplanner calculates the effectiveness of each crop protection product on the basis of the local weather forecast. With the SmartFarm sensors you measure your crop conditions, after which the advice is more accurate.
