Bacterial wilts of tomato, pepper, eggplant, and Irish potato caused by R. solanacearum were among the first diseases that Erwin Frink Smith proved to be caused by a bacterial pathogen. Because of its devastating lethality, R. solanacearum is now one of the more intensively studied phytopathogenic bacteria, and bacterial wilt of tomato is a ...
Potato rot nematode Ditylenchus destructor. Root knot nematode ... Exact cause(s) unknown, chemical injury, viruses or other pathogens. References
The European potato failure was a food crisis caused by potato blight that struck Northern and Western Europe in the mid-1840s. The time is also known as the Hungry Forties . While the crisis produced excess mortality and suffering across the affected areas, particularly affected were the Scottish Highlands , with the Highland Potato Famine and ...
The chronology of the Great Famine (Irish: An Gorta Mór [1] or An Drochshaol, lit. ' The Bad Life ') documents a period of Irish history between 29 November 1845 and 1852 [2] during which time the population of Ireland was reduced by 20 to 25 percent. [3] The proximate cause was famine resulting from a potato disease commonly known as late ...
Therefore, the most economical and effective alternatives to control potato degeneration are exactly the same as those necessary to control viruses in the crop: to obtain, on the one hand, seed tubers free of viruses and other pathogens through micropropagation or in vitro cultivation of potato varieties and, on the other hand, to develop new ...
They include some of the most destructive plant pathogens, such as the causal agents of potato late blight [9] root rot, [10] and sudden oak death. [11] [12] Despite not being closely related to the fungi, the oomycetes have developed similar infection strategies, using effector proteins to turn off a plant's defenses. [13]
Fusarium dry rot is one of the most common potato diseases. It is caused by fungi in the genus Fusarium.This fungi causes a variety of colored rots in potatoes. This pathogen, while having both a sexual and asexual form, stays in an asexual cycle due to the way it spreads.
