• "Cochliobolus miyabeanus " may cause wide range of symptoms.
• Its sexual stage ( teleomorph ) is called " Cochliobolus victoriae ".
• Other known severe crop loss cases caused by " Cochliobolus miyabeanus " are globally distributed.
• Crosses between different species of " Cochliobolus " are possible, producing offspring differing in conidial morphology.
• Rainfall and drought-The first factor affecting " Cochliobolus miyabeanus " life cycle is rainfall and drought.
• Temperature and humidity-Another factor affecting disease development for " Cochliobolus miyabeanus " is temperature and humidity.
• The teleomorphic state of the type species " Curvularia lunata " is " Cochliobolus lunatus " ( Fam.
• ""'Cochliobolus lunatus " "'is a fungal plant pathogen that can cause disease in humans and other animals.
• "Cochliobolus miyabeanus " is an important pathogen because it causes a common rice disease happening worldwide that results in high level of crop yield losses.
• The anamorph of this fungus is known as " Curvularia lunata ", while " Cochliobolus lunatus " denotes the teleomorph or sexual state.
• The genus " Cochliobolus " is distinguished by the presence of dark to black ascomata with a unilocular, globose pseudothecium and a short, cylindrical neck.
• Variation in mycotoxin production by " Cochliobolus " species is used to distinguish some taxa and these mycotoxins are host-specific and non-host specific.
• Among the plant pathogens that affect this genus are the sac fungus " Cochliobolus sativus ", which has been noted on common barnyard grass, and rice hoja blanca virus.
• They are, however, the same biological entity . " Cochliobolus lunatus " is the most commonly reported species in clinical cases of reported " Cochliobolus " infection.
• They are, however, the same biological entity . " Cochliobolus lunatus " is the most commonly reported species in clinical cases of reported " Cochliobolus " infection.
• The sac fungus " Bipolaris sorokiniana " ( anamorph of " Cochliobolus sativus " ) and others can cause fatal root rot in plants of this genus if the roots get too wet and cold.
• United States treated this pathogen as a biological weapon when attacking Japan during the Second World War; " Cochliobolus miyabeanus " was used as the biological anti-crop agent that attacked staple foods in Japan, which was rice.
• In recent years, Helminthosporium leaf blights ( HLB ), caused by both " Cochliobolus sativus " and " Pyrenophora tritici-repentis ", have emerged as serious concerns for wheat cultivation in the developing world . overall 22 % to complete failure of crop under severe epidemics.
• It is likely that these two systems act caviae " which feed on " Rhizoctonia solani ", " Sclerotium rolfsii " and " Fusarium oxysporum ", and some myxobacteria which feed on " Cochliobolus miyabeanus " and " Rhizoctonia solani ".
• Infection efficiency is influenced by humidity level of the leaves, and lowered minimum temperature for crop cultivation favors its epidemics . " Cochliobolus miyabeanus " grows well at lower temperatures during its developmental stages compared to the grown up stage, so if high temperature is maintained in the area it is likely that the farmers can restrict growth of the pathogen.
