Beginning in 1993, Florida’s citrus industry has been invaded by citrus leafminer (Phyllocnistis citrella Stainton, Lepidoptera: Gracillariidae), brown citrus aphid (Toxoptera citricida Kirkaldy, Homoptera: Aphididae), and the Asian citrus psylla (Diaphorina citri Kuwayama, Homoptera: Psyllidae). The source(s) of these pests remain unknown but other countries in the Caribbean, as well as Centra...

Bacterial type III secretion systems deliver protein virulence factors to host cells. Here we characterize the interaction between HrpB2, a small protein secreted by the Xanthomonas citri subsp. citri type III secretion system, and the cytosolic domain of the inner membrane protein HrcU, a paralog of the flagellar protein FlhB. We show that a recombinant fragment corresponding to the C-terminal...

Copper is the most efficient pesticide for control of citrus canker (Xanthomonas citri subsp. citri). To mitigate environmental impacts and costs, copper sprays in orchards are being optimized based on tree row volume (TRV). A previous investigation allowed significant reductions spray rates. Nevertheless, results also indicated need additional studies. The aim this work was to assess whether b...

xanthomonas citri subsp citri (xcc) is responsible for one of the most destructive diseases of citrus fruits, asiatic citrus canker. based on the bacterial host range, the pathogenic forms, a, a*, and aw have been identified. a*-type strains are not well characterized and they have been reported to differ from other a-type strains on the basis of biochemical and genetic characteristics. in this...


 Citrus fruit is a plant that very susceptible to disease. Diseases often attack citrus fruits are usually in the form of spots on fruit. Diagnostics diseases carried out by experts manually which can cause results be subjective. Not all farmers diagnosing diseases. Therefore, this study proposes system for using computer vision based deep learning. So model used computers with limited re...
