Chlorothalonil (Bravo / Echo / Equus) yog FRAC M5 fungicide, paub tias nws yog ib qho yooj yim mus use raws li ib tug neeg sawv cev khoom los yog raws li ib tug tank mix tus khub, thiab muaj peev xwm tiv thaiv tau ntau yam kab mob.Qee cov piv txwv ntawm chlorothalonil fungicides siv los tswj cov kab mob xws li txiv lws suav ryegrass nplooj blight thiab txiv hmab txiv ntoo rot, lws suav lig blight, txiv lws suav anthracnose ripe txiv hmab txiv ntoo rot, cercospora thiab / los yog xim av nplooj thiab celery petiole blight, Alternaria alternata thiab txiav cercospora nplooj, liab doog nplooj thiab petiole. Cov pob txha ntawm cov asparagus dawb, ntshav me me ntawm dos, qej thiab leeks, thiab Alternaria alternata ntawm dib, taub dag, taub dag thiab melons.Ntxiv nrog rau cov qauv kab mob no, chlorothalonil kuj tseem ua haujlwm tseem ceeb hauv lub tank sib xyaw ua ke thiab tuaj yeem siv los ua cov tshuaj tua kab mob tiv thaiv kab mob downy mildew.Vim nws ntau hom kev nqis tes ua, cov khoom siv tuaj yeem siv ntau zaus thiab ua ntu zus.
Thaum lub sij hawm tsis txaus, lwm yam fungicides siv tau, thiab lwm yam fungicides tuaj yeem raug xaiv los xyuas kom meej tias cov qoob loo tiv thaiv.Michigan State University Extension Department pom zoo kom koj ua tib zoo mloog rau FRAC code thaum txiav txim siab siv lwm yam kab mob fungicide.
Mancozeb muaj xws li Manzate lossis Dithane.Nws yog ib qho dav-spectrum FRAC M3 fungicide nrog cov teebmeem zoo sib xws rau chlorothalonil.Nws tuaj yeem siv los sau ntau qhov khoob uas yuav ua rau muaj teeb meem vim qhov tsis txaus ntawm chlorothalonil.Hmoov tsis zoo, daim ntawv lo mancozeb tsis muaj qee cov ntaub ntawv sau npe qoob loo, suav nrog Brussels sprouts, carrots, broccoli, celery thiab leeks.Ib yam li ntawd, lub sijhawm ua ntej sau qoob rau txiv nkhaus taw yog qhov ntev 5 hnub, uas yuav ua rau nws nyuaj rau siv rau kev loj hlob sai thiab ntau cov qoob loo xws li dib, lub caij ntuj sov squash thiab lub caij ntuj sov squash.Vim nws ntau hom kev nqis tes ua, cov khoom siv tuaj yeem siv ntau zaus thiab ua ntu zus, tab sis qee cov formulations tsuas yog siv rau asparagus plaub zaug ntawm feem ntau thiab vine qoob loo rau yim daim ntawv thov feem ntau.
Hloov yog qhov dav-spectrum tshuaj tua kab mob fungicide uas yog kev sib xyaw ntawm fludemonil (FRAC 9) thiab ciprodinil (FRAC 12).Nws yog active tiv thaiv Alternaria nplooj blight nyob rau hauv carrots, Alternaria nplooj me ntsis nyob rau hauv broccoli, Brussels sprouts, cabbage thiab cauliflower, crater rot nyob rau hauv celery, thiab ntshav me ntsis nyob rau hauv dos.Nws muaj lub sijhawm ua ntej sau qoob loo piv rau cov chlorothalonil.Hauv kev rape, carrots, celery thiab dos, chlorothalonil tuaj yeem hloov chlorothalonil.Nws daim ntawv lo yog txwv rau nplooj zaub thiab hauv paus zaub.Tom qab siv lub Hloov ob zaug, thov tig nws ua cov tshuaj tua kab mob sawv cev rau lwm tus FRAC code, thiab tom qab ntawd rov siv dua
Scala yog ib tug dav-spectrum systemic fungicide ua los ntawm azoxystrobin (FRAC 9).Nws tsis muaj daim ntawv lo rau rape, vines, thiab asparagus.Txawm li cas los xij, nws tuaj yeem hloov cov ntshav me me hauv qej, leeks thiab dos.Nws muaj lub sijhawm tom qab sau qoob loo zoo ib yam li chlorothalonil.
Tanos yog dav-spectrum, hauv zos systemic thiab hu rau bactericide, kev sib xyaw ntawm famoxalone (FRAC 11) thiab cyclophenoxy oxime (FRAC 27).Nws muaj txiaj ntsig zoo hauv kev tswj hwm Alternaria alternata thiab tau siv los ua lub tank sib xyaw nrog cov kab mob fungicides tshwj xeeb.Tsis muaj cov ntawv sau rau asparagus, broccoli, Brussels sprouts, cabbage, carrots, broccoli los yog celery.Nws tuaj yeem siv rau txhua lub vines, txiv lws suav, kua txob, dos, qej thiab leeks.Feem ntau, lub sijhawm luv luv ua ntej sau qoob loo luv dua li cov khoom Mancozeb, tab sis rau cov qoob loo, txiv lws suav thiab kua txob, lub sijhawm sau qoob loo tseem yog peb hnub ntev dua li cov khoom chlorothalonil.Yog tias siv ntau zaus, cov khoom hauv FRAC 11 muaj kev pheej hmoo siab dua ntawm cov tshuaj tiv thaiv kab mob.Thaum siv Tanos hauv qhov kev pab cuam txau, ib txwm tig nws mus rau lwm tus FRAC code.
Pristine yog ib tug dav-spectrum, hauv zos systemic thiab cross-layer bactericide, uas yog tsim los ntawm combining cov bactericides FRAC (FRAC 11) thiab Carboxamide (FRAC 7).Tam sim no, nws tsis tau sau npe asparagus, canola, txiv lws suav, kua txob thiab qos yaj ywm.Nws tuaj yeem siv rau qhov chaw ntawm Bravo rau Alternaria nplooj blight nyob rau hauv vines thiab carrots, Alternaria nplooj nyob rau hauv celery, thiab liab doog nyob rau hauv qej, leeks thiab dos.Lub caij ua ntej sau qoob loo zoo ib yam li chlorothalonil.Qhov siab tshaj plaws daim ntawv thov txwv rau vine qoob loo yog plaub zaug hauv ib xyoos, thiab qhov siab tshaj plaws daim ntawv thov txwv rau dos, qej, thiab leeks yog rau lub xyoo.Pristine tsuas yog tso cai siv celery ob zaug hauv ib xyoos.Nyob rau hauv cov txheej txheem txau, nco ntsoov kom deb ntawm FRAC 11 cov khoom txhua zaus koj siv Pristine.
Quadris / Heritage, Cabrio / Headline lossis Flint / Lub pov haum yog dav-spectrum topical system FRAC 11 fungicides.Cov tshuaj strobilurin-based fungicides tau sau npe siv rau hauv feem ntau cov qoob loo zaub, thiab feem ntau lub sijhawm ua ntej sau qoob loo yog 0 hnub.Cov khoom no muaj keeb kwm zoo ntawm kev kho ntau yam kab mob fungal.Txawm li cas los xij, FRAC 11 cone globulin muaj peev xwm tsim cov tshuaj tiv thaiv kab mob los ntawm kev siv dua.Txhawm rau tiv thaiv kev siv strobilurin thiab ncua kev txhim kho ntawm kev tiv thaiv, cov ntawv tam sim no txwv cov kev tswj hwm sib law liag tau tso cai hauv ib xyoos.Rau feem ntau cov qoob loo, Quadris / Heritage tsuas tso cai rau ob daim ntawv thov sib law liag, Cabrio / Headline tsuas tso cai rau ib daim ntawv thov txuas ntxiv, thiab Flint / Lub pov haum tsuas pub plaub daim ntawv thov siab tshaj plaws.
