This graph shows the number of water traps analysed by CSL each year, from 1996 to 2005. Many of our customers have joined the scheme because of personal recommendation by another commercial grower. If you would like to join this expanding number of growers concerned with aphid transmitted diseases, then please e-mail the scheme administrator with your details and you will be contacted either immediately or in advance of the 2006 growing season (your choice) to discuss the details.
