Abstract

The weed wiping technique is widely used in arable crops and grassland to control volunteer crops like weed beet and general weed populations like bracken, rushes, thistles and ragwort in grassland, red rice in rice field (www.monsanto-ag.co.uk) and volunteer potatoes in sugar beets. The working principle of the machine is generally based on the difference in height between the weed plants and the crops. The European Directive 128/2009 provides that also wiper devices are subject to a mandatory functional inspection. In these type of in Pesticide Application Equipment (PAE), herbicide/chemical mixture concentrated (up to 60%, fig 1 – type A) or herbicide/chemical product not diluted (fig 3 – Type B) is supplied to an absorbent surface (e.g. cotton, sponge roller with carpet for type A, fig 2, and cord for type B). The herbicide/chemical product soaked surface only contacts target that in same case (e.g weed control in rice -sugar beets) can be taller than the crop. Chemical is transferred to the surface of the target as the applicator "wipes" over them. At present no EN or ISO Standards for functional inspections are available. This considered, a Spice Advice on how to make their functional inspection, following when possible the harmonized Standard EN ISO 16122 part 1& 2, has been developed inside the SPISE TWG .
