Variable Rate Application of Fungicides

  • Chapter
  • First Online:
Precision Crop Protection - the Challenge and Use of Heterogeneity

Abstract

Plant diseases often occur in patches within the field. But real-time sensor technology for automatic disease detection which would be a prerequisite for demand related fungicide application is commercially not yet available. In heterogeneous fields growth conditions vary greatly due to soil quality differences. Consequently there exist subareas with varying biomass which affect yield at harvest time. In high biomass and yield subareas the Leaf Area Index (LAI) is greater than in low biomass subareas. In cereals LAI can serve as a parameter to adapt application rate to the growth differences in fields. Sensor controlled variable rate field sprayer technology therefore meets the economic and ecological demands of process optimisation in the production of primary plant goods.
