A PHLID Model for Tomato Bacterial Canker Predicting on Epidemics of the Pathogen.

A pathogen, healthy, latently infected, infectious, and diseased plant (PHLID) model for botanical epidemics was defined for tomato bacterial canker (TBC) caused by the pathogenic plant bacteria, subsp. (). First, the incubation period had to be defined to develop this type of model.

An HLD Model for Tomato Bacterial Canker Focusing on Epidemics of the Pathogen Due to Cutting by Infected Scissors.

A healthy, latently infected, diseased (HLD) plant model for botanical epidemics was defined for tomato bacterial canker (TBC) caused by the pathogenic plant bacteria, subsp. (). To estimate the infection probability parameter, inoculation experiments were conducted in which it was assumed that infection is transferred to healthy plants through contaminated scissors used to cut symptomless infected plants.

Biological control for grapevine crown gall using nonpathogenic Rhizobium vitis strain ARK-1.

Crown gall of grapevine, which is caused by tumorigenic Rhizobium vitis, is the most important bacterial disease of grapevine throughout the world. Screening tests of biological control agents resulted in the discovery of a nonpathogenic R. vitis strain ARK-1.

Evaluation of the Nonpathogenic Agrobacterium vitis Strain ARK-1 for Crown Gall Control in Diverse Plant Species.

The nonpathogenic strain of Agrobacterium (=Rhizobium) vitis ARK-1 is a biological agent able to effectively control grapevine crown gall. In this study, treating apple, Japanese pear, peach, rose, and tomato by soaking the roots in a cell suspension of ARK-1 before planting into soil infected with tumorigenic Agrobacterium spp. reduced the number of plants developing crown gall tumors.
