The first SI was signed by the Minister of Agriculture in June 2009. It was SI No. 191 of 2009 and forbid the movement of citrus plants to any location in Belize. The idea of this SI was to prevent the movement of citrus plants until a delimiting survey, to determine the spread of the disease, had been completed. This survey would then inform from which location to which location it would be relatively safe to move plants without creating unnecessary risk for spreading the disease around the industry.
The delimiting survey showed that the majority of the incidences of HLB-disease were in the eastern and central, Stann Creek District. As this is also the area where most nursery plants in the industry are produced and as these nursery plants had been produced in the open (un-screened) concerns were expressed that there was strong likelihood that these plants would be infected with the HLB-greening bacteria. The possibility of potentially-HLB-infected plants being moved into areas where low to no incidences of HLB had been found (along the Western Highway, for example), has been and continues to be a major concern for the citrus industry and for conscientious growers.
