Prothioconazole yog ib tug broad-spectrum triazolethione fungicide tsim thiab launched nyob rau hauv 2004. Nws muaj lub luag hauj lwm ntawm kev tiv thaiv, kho thiab tshem tawm, thiab muaj zoo systemic zog. Nws yog tsuas yog siv los tiv thaiv thiab tswj ntau yam kab mob ntawm cov qoob loo cereal (xws li nplej, barley, thiab lwm yam), rape, txiv laum huab xeeb, nplej, taum qoob loo thiab lwm yam. Nws tuaj yeem siv los ua cov tshuaj tsuag foliar lossis ua tshuaj kho cov noob. Kev ntsuam xyuas kev ua tau zoo qhia tau hais tias prothioconazole tsis tsuas yog tswj cov pob txha pob txha, tab sis kuj txo qis gibberellin.
Thioconazole tau tsim sai heev txij li thaum nws tso tawm nyob rau hauv 2004 thiab tam sim no tau dhau los ua lub thib ob loj tshaj plaws fungicide kev lag luam thiab ntau yam fungicides loj tshaj plaws rau cov nplej.
Tam sim no lub khw tseem ceeb rau prothioconazole tseem yog cov teb chaws Europe thiab Tebchaws Meskas, nrog rau cov lag luam Esxias tsawg dua.
Mechanism ntawm kev ua thiab kev siv
Piv nrog cov tshuaj triazole fungicides, prothioconazole qhia txog thione qauv rau hauv cov qauv molecular. Nws cov txheej txheem ntawm kev ua haujlwm yog inhibit qhov demethylation ntawm 14- txoj hauj lwm lanosterol los yog 2, 4-methylenedihydrolanosterol, tus precursor hauv fungi, uas yog, demethylation inhibitors (DMIs). Nws tsis tsuas yog muaj kev ua haujlwm zoo, kev tiv thaiv zoo heev thiab kev ua kom tshem tawm, tab sis kuj muaj cov nyhuv ntev.
Los ntawm ntau qhov kev sim teb, cov txiaj ntsig tau pom tias prothioconazole muaj qhov dav ntawm cov kab mob bactericidal dua li cov tshuaj triazole fungicides, thiab tsis tsuas yog muaj cov tshuaj lom neeg lom neeg zoo los tswj cov hom phiaj. Nws tseem muaj kev nyab xeeb rau cov qoob loo thiab ib puag ncig, muaj kev tiv thaiv kab mob zoo thiab kev kho mob, thiab ua rau muaj kev tsim khoom ntau.
Vim hais tias prothioconazole muaj cov yam ntxwv ntawm kev ua haujlwm siab, dav spectrum thiab kev nyab xeeb, nws yog dav siv hauv cov nplej, taum, rapeseed, mov, txiv laum huab xeeb, qab zib beets, thiab lwm yam thoob ntiaj teb. Piv txwv li, nws muaj ib tug dav bactericidal spectrum thiab muaj kev tswj zoo ntawm cov kab mob, thiab muaj kev tswj zoo heev ntawm yuav luag tag nrho cov kab mob fungal ntawm cereals. Xws li powdery mildew, scab, sheath blight thiab xeb, thiab lwm yam. Nws tuaj yeem tiv thaiv thiab tswj cov kab mob hauv av ntawm rape thiab txiv laum huab xeeb nrog rau cov kab mob loj, xws li grey pwm, xim av, xim dub, xeb thiab dub shank. . Raws li kev tshawb fawb, cov pa ib txwm noj ntawm prothioconazole yog nyob ib ncig ntawm 200g / hm2. Ntawm qhov koob tshuaj no, kev ua haujlwm zoo dua lossis sib npaug ntawm cov tshuaj fungicides, xws li epoxiconazole, tebuconazole, cyprodinil, thiab lwm yam.
Prothioconazole tam sim no tau sau npe rau ntau yam kab mob qoob loo hauv cheeb tsam sib txawv, tab sis nws qhov ntau npaum li cas yog siv rau cov nplej (xws li cov nplej, barley, oats, buckwheat, thiab lwm yam) thiab taum pauv, tshwj xeeb tshaj yog cov nplej thiab taum pauv.
Kev Ua Lag Luam Cia Siab
Prothioconazole muaj qhov zoo ntawm cov kab mob dav dav, kev ua haujlwm zoo, kev tiv thaiv siab, kev kho thiab tshem tawm kev ua haujlwm, thiab lub sijhawm siv tau ntev. Hauv kev lag luam thoob ntiaj teb, prothioconazole muaj txiaj ntsig zoo rau cov kab mob pwm, kab mob, kab mob thiab xeb hauv cov qoob loo xws li taum pauv thiab nplej thiab tau siv ntau xyoo. Prothioconazole tseem tuaj yeem cuam tshuam nrog kev tiv thaiv los ntawm kev siv lub sijhawm ntev ntawm ib tus neeg sawv cev thiab kev npaj ua ke xws li carbendazim, thiram, thiophanate-methyl, epoxiconazole, prochloraz, tebuconazole, thiab hexaconazole. Tam sim no, prothioconazole tau dhau los ua cov tshuaj pom zoo los ntawm Agricultural Technology Center rau kev tiv thaiv thiab kho "ob kab mob" ntawm cov nplej. Nws muaj kev ua lag luam zoo daim ntawv thov kev cia siab thiab tsim nyog ntawm kev nce qib thiab kev thov tshawb fawb.
