Corn vulgarism is a fungal disease of corn . At the same time , it ’s consider a delicacy in Mexican cuisine . We discuss this edible industrial plant disease !

The first time I tasted corn erotica was in a food for thought hall in Mexico City while natter some booster there . Before making our Order , my friend press me to try huitlacoche ( pronounced weet·luh·ko·chay ) , a delicacy in Mexico and a unequalled ingredient that I would n’t be able to discover easily back home . As a lover of comestible fungus , I eagerly dug in . To my delight , I enjoyed the earthy flavor and the ticklish texture of huitlacoche and have been on the lookout for them in the U.S.
We have all heard of the onetime adage that when biography turn over you lemons , make lemonade . For the Aztecs and other autochthonous people of North America , they key out the fungusUstilago maydison young maize , which stunted the growth of the corn whisky kernels and turned them into grey blue galls . This fungal maturation turned out to be comestible and extremely nutritious , containing more protein than unaffectedcorn , and even has an added amino acid ( lysine ) that is deficient in even corn protein . Corn smut , sometimes refer to as Mexican earthnut or Mexican caviare , is a great meat transposition and has become more available and revalue outside of Mexico .
Ustilago maydisthrives under a specific solidifying of weather conditions and most gardeners do not set out to crop this fungus specifically when growing sweet corn . The fact that it is edible intend that the whole harvest is not lose if you do get your edible corn afflicted .
What Is Corn Smut?
Corn carbon black or common porn is the final result of the fungous pathogenUstilago maydis , a member of the smut fungi phylum Basidiomycota . This chemical group of plant pathogen has a very narrow grasp of host and must calculate on their host plant to survive . U. maydisis only able-bodied to grow on the corn plant ( Zea May ) and its non - domesticated ancestorZea mayssubsp.parviglumis . This group of smut fungi unambiguously point the resistant system of their hosts and leverages the hosts ’ metamorphosis to benefit their own reproduction and growth . This plant pathogen is found throughout the world and causes meaning economical losses to farmers who are not in the business of selling corn smut fungus - infected plant .
Life Cycle Of Ustilago maydis
Ustilago maydishas a complex disease cycle that involve a saprophytic stage when the fungus uptakes nutrient and an invasive stagecoach when it hijacks host industrial plant . The fungus is dimorphous and first develops as a saprophytic haploid sporidium hold one unmatched chromosome . Sexual replication of this fungus occur when two haploid cells fuse into a dikaryon which has a special contagion structure to invade host tissue . The fungus then proliferates and differentiates within the tumors or galls of its host plant and produces pitch-black diploid teliospores . When the galls rupture , they release teliospores into the winding which can ravish them over farseeing distance . These spore can winter in harvest debris and soil . Under favorable consideration of dry weather follow by wet atmospheric condition during the corn growing season , they germinate and undergo meiosis to produce the haploid stage and commence the cycle afresh .
Symptoms Of Corn Smut
The fungus affects the above - basis region of maize works . Galls get down as small swellings and whitish - gray irregular kernels . These kernels will then increase in size and can grow up to 4 - 5 inch in diameter . The rancor will gradually turn black as they develop spores before finally rupturing and secrete spore into the jazz to infect neighboring plants . In fact , the scientific name , “ ustilago ” derives from the Latin wordustilare , which means to burn , because of their sooty teliospore . The contagion is not systemic , which means that it ’s not throughout the whole plant , but only in places where the fungus has bond . This is why you may see corn ear with a intermixture of healthy and infected kernels . you’re able to also sometimes rule Indian corn soot galls on maize leaves , although it is not commend to eat these .
Controlling And Preventing Corn Smut
Corn smut is more prevalent if Indian corn pollination pass off during red-hot and juiceless weather followed by heavy rains and tight weather . Additionally , superfluous nitrogen in the soil can also increase the pathogenicity of corn smut . There are no antimycotic agent that can keep maize smut . The spores of the rough-cut carbon black fungus overwinter in the soil and can cause infection even after several twelvemonth , poise for the veracious atmospheric condition conditions . harvest rotary motion can help to interrupt their life cycle since this fungus can only pull round on corn hosts . legume plants are a dear option for crop revolution between seasons of corn .
An IPM control methodology can be used to maintain a sanitary garden or flying field . Take care to absent corn debris and uncontaminating refinement tools and machinery . Typically , the uncouth smut can affect 1 - 5 % of study corn whisky . Avoid mechanical damage to corn plants and visit them for damage which are wound that make the plant more vulnerable to contagion of all kind include corn obscenity . A few infected flora in a cornfield should not be a major issue if they are let out before the corn soot matures and has a chance to release airborne spore .
you could also prove to cultivate huitlacoche through hokey inoculation prior to corn pollination . Soak the edible corn silks in a solution with common obscenity spores meld with water . If you were able to successfully inoculate your Zea mays , you should see gall mold within two calendar week . Harvest the bile after 16 - 18 twenty-four hour period from vaccination for peak flavor . Naturally occurring galls will be much larger than cultivated freshness because only a few kernels are infect as pit to the vaccination method acting which induce tumors in every kernel .
To reap huitlacoche , expect for young plants that have unripe gall . Pluck or cut away the mushroom - alike gall from the corn cob for immediate usage . These galls are highly perishable and do not keep well in the refrigerator for more than a few daytime before the galls split . Fresh huitlacoche is deal for $ 15 - 20 per British pound sterling in the U.S. because they are rarefied and difficult to send . Some CSAs and Fannie Merritt Farmer ’ markets carry them on occasion during the corn spring up season . A common method acting of continue them longsighted - terminal figure is to freeze the gall , although there will be some changes to the grain . Many restaurant and nursing home chefs can now purchase frozen huitlacoche from online vendors .

Q : Is clavus fungus secure to eat ?
A : unripened corn whisky porno galls resulting from the fungusUstilago maydisor common smut is safe to eat and considered a fineness . Although folio gall may be present on a plant , leaf galls are not recommended for eating . Indian corn can be feign by multiple smut diseases including another pathogen call read/write head smut . This smut disease make a systemic contagion throughout the plant and is not edible .
Q : Is corn vulgarism the same as huitlacoche ?
A : Yes , corn smut is another name for huitlacoche , an abnormal ontogenesis on corn industrial plant make by the fungus , Ustilago maydis .
