- •
Disease attack of septoria tritici blotch (STB) and yellow rust in winter wheat increased with increasing crop biomass.
- •
A significant biomass × fungicide dose rate interaction indicates a potential for optimizing fungicide inputs site-specific.
- •
Spray deposits on 1st leaf and 2nd leaf varied marginally whereas significant differences were observed on the 3rd leaf.
- •
This indicates that spray deposition on the 3rd leaf has a significant influence on disease control and crop yield.
