pythium การใช้

• Pythium and Rhizoctonia are both seedling diseases of the cotton plant.
• Fungus that causes stem rot are Rhizoctonia, Fusarium and Pythium.
• Seedlings may be killed by " Pythium " damping off.
• Recently, azoxystrobin has proven effective in controlling both rhizoctonia and pythium.
• Such invasive fungi include Fusarium, Pythium, and Lasiodiplodia.
• It is also active against certain oomycetes, such as Pythium, making it useful for controlling damping off.
• "Pythium irregulare ", like most oomycetes, has a life cycle with sexual and asexual stages.
• Both authors wrote that a Cretan deserter informed Perseus, who sent 2000 Macedonians and 10, 000 mercenaries to Pythium.
• In 1902, Butler was transferred to rusts in 1906 and his research on " Pythium " in 1907.
• In order to identify " Pythium irregulare " it is necessary to isolate the organism and observe it microscopically.
• Cultivars from arid sandy areas are very susceptible to root rot fungus on poorly drained soils, specifically Fusarium, Pythium and Rhizotona.
• It can be used to control " Pythium " in a number of vegetable crops, and " Phytophthora " in peas.
• Pythium often develops into these streaks because it is the direction of water movement ( drainage ) most often ruts from golf carts and mowing equipment.
• Hydrogen peroxide is also added to nutrient solutions when there is suspicion that the anaerobic pythium root rot mold has begun to proliferate on the roots'surfaces.
• Damping-Off is a disease in temperate areas caused by soil inhabiting oomycetes like " Phytophthora cactorum " and " Pythium " spp.
• Therefore, growers who plant early are advised to use in-furrow fungicides for control : PNCB and iprodione for Rhizoctonia and etridiazole and mefenoxam for pythium.
• "Pythium irregulare " has a very broad host range, including many agronomically and horticulturally important crops and is found on every continent except for Antarctica.
• The traditional method of culturing is on a growth medium selective against fungi ( and, in some cases, against other oomycetes such as " Pythium " species ).
• In field crops, damage by " Pythium " spp . is often limited to the area affected, as the motile zoospores require ample surface water to travel long distances.
• The species was formerly placed in the genus " Pythium ", but that genus has been divided into five distinct clades, each characterized by the morphology of the sporangium.
