Protozoan diseases causes in plants?
Protozoan diseases in plants are relatively rare. One example is Plasmodiophora brassicae, which causes clubroot disease in cruciferous vegetables like cabbage and broccoli. Another example is Phytophthora infestans, a water mold that causes late blight in potatoes and tomatoes.
Is Potato blight a bacteria or virus?
Potato blight, also known as late blight, is caused by a water mold called Phytophthora infestans, which is neither a bacteria nor a virus. It is a type of oomycete, which is a group of fungus-like microorganisms that can cause plant diseases.
Fungus like protist that includes some types of what?
Phytophthora is a fungus-like protist that includes some types of water molds. These organisms are known to cause diseases in plants and are considered a significant pathogen in agriculture. Phytophthora infestans, for example, is the causal agent of late blight in potatoes and tomatoes.
What are examples of plant diseases that water molds cause?
Water molds can cause diseases such as downy mildew, pythium root rot, and phytophthora blight in plants. These diseases are characterized by symptoms such as yellowing leaves, wilting, and root decay, which can ultimately lead to plant death if left untreated. Preventive measures such as proper drainage and fungicide treatments can help manage water mold diseases in plants.
What are some genus species names of fungus like protists?
Some examples of genus species names of fungus-like protists are Phytophthora infestans (causes late blight in plants), Plasmodiophora brassicae (causes clubroot disease in cruciferous plants), and Dictyostelium discoideum (a cellular slime mold).
What type of microbe causes potato blight?
It depends on which type of potato blight you are referring to.Early blight -- caused by Alternaria solani, a fungal pathogen.Late blight -- caused by Phytophthora infestans, an oomycete.

What is an example of Oomycota?
An example of Oomycota is Phytophthora infestans, which causes late blight in potatoes and tomatoes. Oomycota are fungus-like organisms that can cause plant diseases.
Common name of Phytophthora infestans?
Potato Blight, Potato Late Blight Agent, Potato Late Blight Fungus
What organisms are affected by the blight?
Blight can affect a variety of plants, including potatoes, tomatoes, peppers, and other crops. The specific organism causing blight can vary; for example, late blight is caused by a fungal-like organism called Phytophthora infestans, while early blight is caused by a fungus called Alternaria solani. These organisms infect and damage the leaves, stems, and fruits of the affected plants.
Why did the potato blight happen?
Only very few varieties of potato were brought to Europe from the New World and so the potatoes cultivated in Europe weren't sufficiently robust to offer strong resistance to diseases, since they lacked genetic diversity. The European potato was, therefore, unable to fight the potato blight, or late blight, and many crops were destroyed. The impact was most felt in Ireland, which had become highly dependent on potatoes: the country lost about a quarter of its population.
Is Potato blight a bacteria or virus?
Potato blight, also known as late blight, is caused by a water mold called Phytophthora infestans, which is neither a bacteria nor a virus. It is a type of oomycete, which is a group of fungus-like microorganisms that can cause plant diseases.
What organism caused the Irish patato blight?
The Irish potato blight, also known as the Great Famine, was caused by a water mold known as Phytophthora infestans. This pathogen spreads rapidly in wet conditions, leading to the widespread destruction of potato crops in Ireland in the mid-19th century.
How did they get to the new world potato famie?
Potatoes are native to the New World, specifically the Americas, and were brought to Europe from there by the Spanish. Is that your question? If your question is about potato famines, the best-known and most drastic and far-reaching was the Irish Potato Famine, between 1845 and 1852. It was caused by a disease known as potato blight, or late blight, which affected potato crops all over Europe. It is generally considered the blight had such a devastating effect because only a very few varieties of potatoes were brought to Europe from the New World and so those farmed in Europe had no real resistance to the disease, which spread rapidly as a result.

What does tomato blight look like?
There are several varieties of tomato blight, many of which are readily distinguishable from each other as well as conditions caused by water or nutrient deficiencies. "THE blight," however, usually refers to late season blight, aka potato blight. It is the primary killer of autumn and winter tomato crops, made even more hazardous by the fact that, as its more colloquial name implies, it can also infect and spread among several other edible plants, most infamously potato crops (having caused the Irish Potato Famine). Distinguishing between late season blight and a less threatening disease that causes similar symptoms in tomato plants, Septoria Leaf Spot, is critical to determining whether diseased tomatoes should be sprayed in an effort to control the disease, or destroyed quickly before an entire community's winter food supply is wiped out. Symptoms of late season blight are the initial appearance of moist brown spots on leaves and fruits. As these spots grow, they become thin brown rings surrounding an irregularly shaped greasy gray area. Eventually the gray areas on the leaves turn dry and papery, though they do not usually fall out as with other types of blight. Black spots may appear on stems as the blight spreads, and in especially damp areas a white fungus may develop on the brown ring surrounding the gray matter. Eventually the leaves turn yellow and die, while the fruits fall from the plant early and become breeding grounds for even more blight. Septoria leaf spot is nearly identical in appearance to late season blight, differing only slightly in pattern of attack (spreading to older leaves and stems earlier than blight). The one distinct difference is the fact that the gray areas on the fruit and leaves develop tiny raised brown pimple-like growths, which are essentially a fruiting body for the leaf spot fungus that late season blight lacks.
