Finding non-chemical ways of inhibiting the growth of weeds from the cracks in concrete block pavements
Reduction of herbicide use in non-agricultural areas is imposed by a growing number of governments, triggering the development of alternative strategies for weed prevention and control. Our weed science unit investigates the weed preventive abilities of different paving types (e.g. paver types, joint filling materials), and determines the required treatment frequency of non-chemical weed control scenarios (based on hot air, hot water, flames, IR, steam) on these pavements. Furthermore, we are optimizing eco-efficiency and efficacy of thermal weed control methods. The negative environmental impact (e.g. atmospheric sink effects) of non-chemical weed control is minimized by integrating weed preventive and curative weed control tools.
A ready to use practical decision tree was developed that will assist landscape designers and architects in designing weed preventive or inhibiting pavements and will assist administrators and contractors in choosing the optimal curative weed control strategy
