The COMPASS system uses computer modelling to help growers apply the optimum amount of pesticide, reducing the amount of chemicals used while maximising crop yields. It can also be used by pesticide developers to design products that are safer and more reliable.
Accuracy
The system was tested on four sites in the USA over ten years where it was found to have 92 per cent accuracy.
The project was led by Professor Colin Brown in the University’s Department of Environment and Geography, in collaboration with colleagues Dr Annika Agatz and Dr Roman Ashauer. The project was funded by Innovate UK in conjunction with agrochemical company Syngenta.
Professor Brown said: “The system takes into account issues such as soil conditions, seasonal variations and the physiology of crops to develop smart pest control strategies that give an accurate estimate of the amount of pesticide required.
“The aim is to boost agricultural productivity but also reduce the environmental burden of excessive pesticide use.”
Applications
The model focused on root damage in maize caused by the corn rootworm but it is expected to have applications across a wide range of agricultural pests.
