Miti yemadomasi inonyanya kubatwa nezvirwere zvefoliar, izvo zvinogona kudziuraya kana kukanganisa goho.Matambudziko aya anoda mishonga yezvipembenene muzvirimwa zvakajairika uye anoita kuti kugadzirwa kwe organic kuome.
Chikwata chemasaenzi chinotungamirwa nePurdue University chakaratidza kuti matomatisi anogona kunge akanyanya kurwara nemhando dzezvirwere nekuti akarasikirwa nedziviriro yakapihwa nemamwe tupukanana evhu.Vatsvakurudzi vakaona kuti hama dzesango uye matomatisi emusango ane hukama nevhu rakanaka revhu anokura, uye ari nani mukurwisana nekutanga kwezvirwere nezvirwere pane zvirimwa zvemazuva ano.
Lori Hoagland, mutevedzeri wapurofesa wekurima zvirimwa, akati: “Uhu howa hunoparadza zvirimwa zvemadomasi zvomusango uye hunosimbisa gadziriro yazvo yokudzivirira zvirwere.”“Nekufamba kwenguva, takarima matomatisi kuti tiwedzere goho neFlavour, asi zvinoita sekunge vakashaya mukana wekubatsirikana neutachiona hwevhu uhu.
Amit K. Jaiswal, muongorori wepashure kuHoagland nePurdue, akapinza 25 yakasiyana-siyana yematomato genotypes ine ivhu rinobatsira fungus Trichoderma harzianum, kubva kumhando yemhuka kusvika kune yekare uye yemazuva ano emhando dzakasiyana-siyana, iyo inowanzoshandiswa kudzivirira zvirwere zvakashata zveFungal uye mabhakitiriya.
Mune mamwe madomasi emhando yemusango, vaongorori vakawana kuti kana zvichienzaniswa nezvirimwa zvisina kucheneswa, midzi yekukura kwemiti inobatwa nefungi inobatsira yaive 526% yakakwirira, uye kureba kwechirimwa kwaive ne90% yakakwirira.Mamwe marudzi emazuva ano ane midzi yekukura kusvika ku50%, asi mamwe asina.Kureba kwemarudzi emazuva ano kwakawedzera ne10% -20%, iyo yakaderera zvikuru kupfuura yemhando dzesango.
Zvadaro, vatsvakurudzi vakaunza maviri pathogenic pathogens kuchirimwa: Botrytis cinerea (necrotic vegetative bhakitiriya inokonzera grey mold) uye Phytophthora (chirwere chinokonzera chirwere) chakakonzera chirwere muma1840s nzara yembatatisi yeIrish.
Kupokana kwemhando yemusango kuBotrytis cinerea nePhytophthora kwakawedzera ne56% ne94%, zvichiteerana.Nekudaro, Trichoderma inotowedzera huwandu hwechirwere chemamwe genotypes, kazhinji muzvirimwa zvemazuva ano.
Jaiswal akati: "Takaona mhinduro yakakosha yemiti yemusango kune fungi inobatsira, nekukura kwakawedzera uye kudzivirira zvirwere."“Patakachinja tichishandisa mhando dzemhando dzemumba muminda yese, takaona kudzikira kwemabhenefiti.”
Ongororo iyi yakaitwa kuburikidza neTomato Organic Management and Improvement Project (TOMI) inotungamirwa neHoagland, nedonzvo rekuwedzera goho nekurwisa zvirwere zvematomatisi.Chikwata cheTOMI chinotsigirwa nemari neNational Institute of Food and Agriculture yeUnited States Department of Agriculture.Vatsvagiri vayo vanobva kuPurdue University, Organic Seed Alliance, North Carolina State University, University of Wisconsin-Madison, North Carolina A&T State University uye Oregon State University.
Hoagland akati timu yake inotarisira kuona iyo yemusango-rudzi rwematomatisi jena rinokonzeresa kudyidzana kwevhu uye kuidzosera mumhando dzazvino.Tarisiro ndeyekuchengetedza maitiro ayo varimi vakasarudza kwezviuru zvemakore, vachitorazve hunhu huya hunoita kuti zvirimwa zvisimbe uye zvibereke.
“Zvirimwa nemavhu zvinogona kugarisana nenzira dzakawanda uye zvichibatsirana, asi takaona kuti zvinomera zvinoberekana zvine humwe hunhu zvinoputsa hukama uhwu.Mune zvimwe zviitiko, tinogona kuona kuti kuwedzera hutachiona hunoita kuti mamwe madomasi ari mudzimba awane chirwere, ”akadaro Hoagland."Chinangwa chedu ndechekutsvaga uye kudzoreredza iwo majini anogona kupa zvirimwa izvi dziviriro uye nzira dzekukura dzaivepo kare."
Gwaro iri rinodzivirirwa nekodzero.Kunze kwekuita chero kwakanaka kwekudzidza kwakavanzika kana zvinangwa zvekutsvagisa, hapana zvirimo zvinogona kukopwa pasina mvumo yakanyorwa.Zvirimo ndezvekutarisa chete.
