First tests of spatially variable rate herbicide application on Durum wheat in Sicily

Abstract

Using the conventional farming system, durum wheat requires the spraying of high herbicide rates. Herbicide residues can cause pollution of soil and ground water. This paper refers to first tests of spatially variable rate herbicide application on durum wheat. The tests showed the effectiveness of the variable rate herbicide application, which allowed an almost even grain yield over the entire field and a saving of 27% of herbicide mixture.
