University of California, Berkeley cov kws tshawb fawb tau sau npe rau pej xeem txoj kev pabcuam hauv kev taug qab tus kabmob uas tua cov ntoo ntoo.
Tau ob xyoos dhau los, cov kws tshawb fawb tau suav nrog cov neeg nyob hauv los sau cov qauv ntoo thiab xa mus rau tsev kawm ntawv Forest Pathology thiab Mycology Laboratory. Lawv tau siv cov ntaub ntawv los tsim ib daim ntawv qhia kev sib kis ntawm cov ntoo qhib tuag tam sim ntawd.
Tus kab mob tsis paub meej tau pom thawj zaug hauv Mill Valley xyoo 1995 thiab txij li ntawd tau tua ntau txhiab tus ntoo nyob rau sab qaum teb California thiab sab qab teb Oregon. Cov kws tshawb fawb kwv yees tus kab mob, kis los ntawm cov nroj tsuag thiab dej, tuaj yeem tua ntau txog 90 feem pua ntawm California cov ntoo qhib thiab cov ntoo qhib dub hauv 25 xyoo.
Qhov phiaj xwm phiaj xwm, tau txais nyiaj los ntawm US Forest Service, yog thawj lub zej zog kev siv zog los tawm tsam cov ntoo qhib tuag tam sim ntawd. Nws muaj txog 240 tus neeg tuaj koom sau ntau dua 1,000 tus qauv xyoo tas los, hais tias Matteo Garbelotto, UC Berkeley hav zoov pathologist thiab lub teb chaws tus kws tshaj lij ntawm cov ntoo qhib tuag tam sim ntawd.
"Qhov no yog ib feem ntawm kev daws teeb meem," Garbelotto hais rau San Francisco Chronicle. "Yog tias peb qhia thiab koom nrog cov tswv cuab ntawm tus kheej, peb tuaj yeem ua qhov sib txawv loj heev."
Thaum pom qhov chaw muaj kab mob, cov tswv tsev tuaj yeem tshem tawm cov ntoo ntoo, uas tuaj yeem ua rau cov ntoo qhib muaj sia nyob ze li kaum npaug. Cov neeg nyob hauv kuj tau hais kom tsis txhob ua cov haujlwm loj uas tuaj yeem cuam tshuam cov av thiab ntoo thaum lub caij ntuj nag vim tias nws tuaj yeem pab kis tus kabmob.
"Txhua lub zej zog uas paub tias lawv muaj tsob ntoo tuag sai sai hauv lawv cov zej zog yuav tsum hais tias, 'Hav Kuv ua ib yam dab tsi zoo dua,' vim tias thaum lub sijhawm koj pom cov ntoo tuag, nws twb lig dhau lawm," Garbelotto hais.
Nyem qhov no rau ib tsab xov xwm tag nrho ntawm Berkeley kev siv zog los taug qab Sudden Oak Tuag.
