Crazy roots, hairy roots, crown gall

galls are formed which break open, releasing many bacteria. These are dispersed by rain and wind and by humans and tools. Until now, no bacteria have been [...] excessive root growth. All four species cause the growth of galls on the stems, which are first white and later turn brown. Only Rhizobium radiobacter causes galls [...] roots, crown gall The primary source of infection by Rhizobium rhizogenes has not yet been defined. The assumption is that the bacteria survive in the soil

Southern blight

growth is observed on the plant’s stem, which may also develop on the adjacent soil. Spherical sclerotia, which are initially white and then darken, also [...] observed. The fruiting bodies are asexual and there are no spores, forming dark brown or black sclerotia which are rounded, irregular, or compact. The sclerotia [...] responsible for root and stem rot, wilting and damping-off of seedlings. It has a wide range of hosts, around 500 botanical species, including dicotyledons

Charcoal rot

fungus in warmer regions, causing charcoal rot. It has a very wide range of host crops, many of which are economically important food crops. Damage symptoms [...] crop residues as microsclerotia. In corn stalks, survival of up to 1.5 years has been reported. The density of the microsclerotia in the soil is directly related [...] therefore not a problem. How to prevent Charcoal rot Plant in fields with no history of the disease Use disease-free planting material Rotate with non-host

Pierce's disease of grapevine

fastidiosa is a gram-negative bacterium which is limited to xylem tissue. It has many hosts, many of which show minor or no symptoms. More and more plant species [...] conditions with frost periods in which the bacteria inside the dormant plants die. Also, in many regions there is no overwintering of adult vectors that [...] susceptible cultivars (within 2-3 years) than in more tolerant cultivars, which may survive more than five years.
