Yakakosha Yambiro yeVarimi veMbatatisi: Kugadzirisa Kunonoka Blight muMichigan
Kunonoka blight, chirwere chinoparadza chezvirimwa zvembatatisi, chakasimbiswa mumunda wekutengesa muSt Joseph County, Michigan, maererano nemushumo waDr. Amanda Gevens kubva kuYunivhesiti yeWisconsin-Madison. Kusimbiswa kwePhytophthora infestans pathogen, genotype US-23, kunosimbisa kukosha kwekukurumidza uye nekuvandudza nzira dzekudzivirira zvirwere kuvarimi vembatatisi mudunhu.
Tsanangudzo yeKupararira
Dambudziko rekupedzisira rakaonekwa musi waChikunguru 23, 2024, muchikamu chidiki chemamita masikweya mashanu munzvimbo yekutengeserana iri kumaodzanyemba kwakadziva kumadokero kweSt Joseph County, kumuganhu neIndiana. Rob Schafer weMid-Michigan Agronomy akakurumidza kushanda pakuongorora uye akagovera ruzivo rwakakosha, zvichiita kuti vagadziri venzvimbo vatore matanho nekukurumidza kuderedza kupararira kwechirwere ichi.
Yakakurudzirwa Maitiro Ekutungamirira
Pakutarisira iyo US-23 genotype yePhytophthora infestans, phenylamide fungicides, kusanganisira mefenoxam uye metalaxyl, inowanzoshanda. Varimi vanokurudzirwa kuita zvirongwa zvekudzivirira mbesa uye kuchengetedza goho zvine hungwaru kudzivirira kuwedzera kupararira. Ngozi iripo yekunonoka blight muMichigan inotangira kubva pasi kusvika pakati, asi dzimwe nzvimbo dzakasangana nemamiriro ezvinhu anokonzeresa chirwere nekuda kwezviitiko zvemvura zhinji uye zvakanyanya mumavhiki apfuura.
Monitoring uye Forecasting
Kufembera kwanonoka blight kuUpper Midwest kunogona kuwanikwa kuburikidza neUW-Madison Vegetable Disease & Insect Forecasting Network, iyo inopa ruzivo rwakakosha mumazinga enjodzi uye inobatsira varimi kutora matanho ekutanga. Chinongedzo chemuenzaniso wekufanotaura ndeichi: YAKO-Madison Vegetable Disease & Insect Forecasting Network.
Zvisinei nemishumo yekutanga muna Chikunguru yekunonoka kuparara mumatunhu eKent neElgin muOntario, Canada, hapana kumwe kuwonekwa kwedunhu kwakanyorwa. Kuenderera mberi kwekuyedza neMSU Mbatata neShuga Beet Pathology chirongwa hachisati chaona Phytophthora infestans DNA mumasamplers e spore akaiswa mukutsvagisa nekutengesa minda muMontcalm County.
mhedziso
Kusimbiswa kwekunonoka kwechirwere ichi muSt. Joseph County kunoshanda sechiyeuchidzo chakakosha kuvarimi vembatatisi kuti varambe vakangwarira uye vakasimba mumaitiro avo ekudzivirira zvirwere. Nekushandisa mishonga yefungidziro inoshanda, kuongorora mamiriro echirimwa, uye kushandisa maturusi ekufanotaura, varimi vanogona kuchengetedza zvirimwa zvavo uye kuchengetedza goho.
