Late blight of potatoes, caused by Phytophthora infestans, is an example of decay originating in tuber infection in the field. The infection is caused by the zoospores found in the soil or that fall onto the tubers from infected foliage during harvest.

Doctoral thesis. ISSNISBN Potato late blight, caused by the oomycete Phytophthora infestans, is one of the most devastating plant diseases worldwide. Late blight, the disease caused by Phytophthora infestans can grow wherever potatoes are grown, yet is most destructive in cool weather and wet conditions (Marshall ).

The genus Phytophthora, known as the “plant destroyer”, is one of the most important group of disease causing organisms. This genus contains the potato blight pathogen, Phytophthora infestans, and the sudden oak death pathogen, Phytophthora tly the latter species is classified as invasive, and a second one, Phytophthora kernoviae, is about to be placed in this category.
Description Phytophthora infestans 150 EPUB
Potato (Solanum tuberosum L.) is the most important crop and Phytophthora infestans (Mont.) de Bary is the oomycete, which was responsible for infamous Irish potato famine during –45 and it continues to cause worldwide devastation of the potato.
Moreover, this disease is re-emerging in the forms of different genotypes and causes huge yield loss in the potato by: 1. Phytophthora Root Rot. Phytophthora species have such a strong preference for moist soils that they are known as water molds.
The infamous species Phytophthora infestans caused the Irish potato famine in the late s and the death of one million Irish. Despite this term, they are now classed in a separate kingdom (the oomycetes) and are no longer considered fungi.
Disease Cycle Click on any picture to see the enlarged image. In most of the United States and Canada, Phytophthora infestans requires a living host to survive between seasons.
Usually it lives in infected potato tubers (Fig. 2), which can survive in storage or the soil (to become volunteers) after harvest or anywhere potatoes might be discarded. The genome sequences of Phytophthora sojae, P. ramorum, P.
infestans and Hyaloperonospora arabidopsidis are published –. Each genome encodes several hundred putative RXLR effectors.
Each genome encodes several hundred putative RXLR by: Phytophthora infestans is a water mould, that causes the serious disease of the potato, late blight or potato blight.(Early blight, caused by Alternaria solani, is also often called potato blight).This disease was a major culprit in the causation of the Irish potato famine and also the Highland potato organism can also infect tomatoes and some other members of the al: Phytophthora infestans.

Late blight was responsible for the European potato famine in the 19th century .It poses a severe threat to potato production worldwide, with estimated annual economic losses of over six billion dollars, mainly due to yield loss and the high cost of fungicide .Cited by: 3.Phytophthora infestans was the infective agent of the potato blight that caused the Great Irish Famine (–), and still remains the most destructive pathogen of Class: Oomycota.
As a result of recent changes in the Phytophthora infestans population in Great Britain, in particular the dominance of one genotype (13_A2) and the possible implications of this change on host resistance ratings, a coordinated programme of testing between SASA and JHI was initiated.
Over 3 years of trials (–), 49 existing cultivars with published resistance ratings of 5 or greater Cited by:
