What is the Difference Between Pythium and Phytophthora

The main difference between Pythium and Phytophthora is that Pythium primarily attacks monocotyledonous herbaceous plants and some species of Pythium attack mammals, fish, and red algae whereas Phytophthora especially attacks dicotyledonous woody trees, shrubs, and herbaceous plants.

Is Pythium a fungus?

Pythium is a genus of parasitic oomycetes. They were formerly classified as fungi. Most species are plant parasites, but Pythium insidiosum is an important pathogen of animals, causing pythiosis. The feet of the fungus gnat are frequently a vector for their transmission.

Is phytophthora a fungus?

What is Phytophthora? Phytophthora (pronounced Fy-TOFF-thor-uh) is a genus of microorganisms in the Stramenopile kingdom which includes water molds, diatoms and brown algae. Phytophthora species resemble true fungi because they grow by means of fine filaments, called hyphae, and produce spores.

Is phytophthora a bacteria?

Phytophthora infestans is an oomycete or water mold, a microorganism that causes the serious potato and tomato disease known as late blight or potato blight. Early blight, caused by Alternaria solani, is also often called "potato blight".

What is Phytophthora spp?

Phytophthora (from Greek φυτόν (phytón), "plant" and φθορά (phthorá), "destruction"; "the plant-destroyer") is a genus of plant-damaging oomycetes (water molds), whose member species are capable of causing enormous economic losses on crops worldwide, as well as environmental damage in natural ecosystems.

How is Pythium treated?

Treat Pythium Blight

Remove thatch to remove sources of the Pythium fungus and to bring the lawn back to health. Block off the infected area from foot traffic. After mowing or aerating, wipe off your blades and tools and even shoes to prevent further spreading of the fungus.

How do you kill Pythium?

Oxy-Plus (Hydrogen Peroxide) is a brilliant product for disease prevention, but at the concentrations necessary to kill active pythium growth and spores it will also damage plants.

Can Phytophthora be treated?

Phytophthora root rot is a worldwide problem that can be treated but not completely eradicated. Infected specimens will likely die, unless removed and destroyed beforehand.

How do you stop Phytophthora?

The most effective way of preventing Phytophthora rot diseases is to provide good drainage and to practice good water management. Along with the appropriate cultural controls, the fungicide fosetyl-al (Aliette) may be used on a number of ornamental plant species to help prevent Phytophthora infections.

How do you kill Phytophthora?

High temperatures have been used to control Phytophthora in many ways. Steam heat is effective to kill Phytophthora in contaminated soil, media or on planting containers such as pots. If you re-use pots you can soak pre-cleaned pots in hot (180°F) water for at least 30 min or use aerated steam (140°F) for 30 min.

Is phytophthora a virus?

In the past few years, several viruses have been characterized in Phytophthora species, including four viruses from Phytophthora infestans, the late blight pathogen, and an endornavirus from an unnamed Phytophthora species from Douglas fir. Studies on Phytophthora viruses have revealed several interesting systems.

How is phytophthora gummosis treated?

Systemic fungicides can control Phytophthora gummosis and copper sprays can be used to protect against infection.

What bacteria caused the potato famine?

Phytophthora infestans is a destructive plant pathogen best known for causing the disease that triggered the Irish potato famine and remains the most costly potato pathogen to manage worldwide.
