Tomato and pepper
XANTVE
Xanthomonas vesicatoria causes bacterial spot in tomatoes and peppers. It produces symptoms such as leaf spots, fruit spots, and defoliation, particularly in warm and humid conditions. The pathogen is seedborne and is considered a high-risk quarantine pest.
2 Known Hosts
Capsicum annuum
pepper
Yes
CABICPC, ISFRPLD, XANTVE-1, XANTVE-3, XANTVE-4, XANTVE-6
Seed is a known pathway for Xanthomonas vesicatoria and has been considered a major source of inoculum.
Yes
dilution plating, identification PCR, pathogenicity assay
These are the recommended methods by ISHI as of July 2017.

biological, chemical, Cultural
Biological: the use of resistant varieties may help. Chemical: hot water and chemical treatments have shown some effectiveness but could reduce germination. Cultural: Using disease-free seeds is critical. Sterilization of tools used is important in reducing spread. Crop rotation is also recommended to prevent carryover in volunteers and crop residues.
