Potential Operator Exposure when Spraying in a Strawberry and Raspberry Tunnel System versus a Conventional Open Field
The pesticide exposure of the operator during the spray application in strawberries and raspberries was measured in a tunnel and a conventional ”open field” cultivating system.When spraying strawberries a front mounted spray boom using four nozzles per row and three rows per swath was used.When spraying raspberries a rear mounted mist blower on a tractor and a trailer sprayer pulled by an ATV were used.A quick and easy passive sampling method was developed in order to get a sensitive and exact measurement of the potential exposure.The samplers consisted of transparent overhead sheets cut to a 10 x 10 em2 standard size.The potential operator exposure was significantly higher for a tunnel system compared with the conventional open field system for strawberry as well as for raspberry.
