Farmers are spraying medically important antibiotics on their trees
In 2016, the Environmental Protection Agency (EPA) allowed citrus farmers to spray streptomycin and oxytetracycline antibiotics on infected groves to protect uninfected trees and try and stop further damage to those trees already infected with Candidatus Liberibacter asiaticus (C.L.a ) the bacteria causing Huanglongbing (HLB) disease. However, the evidence of effectiveness is not firmly established even though 650,000 pounds of streptomycin were authorized by the EPA could be sprayed on orchards each year. Fears are that using broad-spectrum human antibiotics on crops would encourage bacteria to select for antibiotic-resistant strains. Trana Discovery stands ready to discover selective agents that would only kill C.L.a leaving the surrounding microbiota and humans unaffected.
