Picarbutrazox ndi carbamate fungicide yokhala ndi mawonekedwe apadera amankhwala komanso njira zatsopano zogwirira ntchito. Imatha kuwongolera bwino matenda oyambitsidwa ndi oomycetes, monga downy mildew, Pythium, pseudoperonospermum ndi Phytophthora, ndi zina zambiri, ndipo imakhala ndi mphamvu yowongolera bwino pa mbewu za downy mildew ndi choyipitsa. Picarbutrazox imakhalanso chida chowongolera kukana ndipo ilibe kutsutsana ndi ma carboxylic acid amides, phenylamides ndi methoxyacrylate fungicides omwe amagwiritsidwa ntchito kwambiri.
Dimethomorph
Dimethomorph ndi fungicide yeniyeni ya oomycetes, zochita zake zimadziwika ndi kuwononga mapangidwe a khoma la cell, ndipo zimakhudza magawo onse a moyo wa oomycetes. Dimethomorph imagwiritsidwa ntchito makamaka popewa ndi kuwononga matenda oyamba ndi fungus, monga downy mildew, downy mildew, choipitsa mochedwa, choipitsa, blackleg ndi matenda ena a mbewu, ndipo itha kugwiritsidwa ntchito pamitengo ya zipatso, masamba ndi mbewu zina.
Diphenoxymorph ndi prophylactic komanso yogwira ntchito, yokhala ndi zotsalira pamasamba a mbewu, zomwe zimapereka chitetezo. Diphenoxymorph ikapopera mbewu, mankhwalawa amatha kulowa mumtundu wamasamba kudzera pamwamba pa masamba, ndikufalikira, kumachita m'malo mwamasamba, omwe angagwiritsidwe ntchito popewa ndikuwongolera matenda a mbewu zambiri zofunika. Izi ndi monga nkhaka downy mildew, grape downy mildew, mbatata late blight, tomato late blight, fodya black shank, ndi zina. Diphenoxymorph ilibe kutsutsana ndi ma phenylamide fungicides omwe amagwiritsidwa ntchito kwambiri (monga metalaxyl), ndipo ali ndi mgwirizano wabwino wamaso. Itha kusakanikirana ndi mitundu ina yamankhwala opha fungicides, monga mancozeb, ndi zina zotero, potero Kukulitsa kuchuluka kwa kutsekereza ndi kuchuluka kwa ntchito.
Cyazofamid+Cymoxanil
Zigawo ziwiri za cyanogen frost ndi frost gland cyanogen ndi zigawo ziwiri za downy mildew ndi mochedwa choipitsa: mpweya wa chisanu uli ndi mphamvu zowonongeka komanso kuyamwa mwadongosolo, ndipo ukhoza kuwonedwa patatha maola 12 mabakiteriya agwirana ndi wothandizira. Chosanjikiza cha nkhungu chimayamba kuuma: chisanu cha mpweya chimakhala ndi ntchito zochiritsira komanso zoteteza, zimatha kupha majeremusi, ndipo zimatha kuyambitsa mbewu kuti zipange ma antibodies motsutsana ndi mildew ndi mildew mochedwa, motero zimakhala ndi zotsatira zokhalitsa, zomwe ndi zabwino kuposa othandizira ena. motsutsana ndi Kutalika kwa matenda omwe tatchulawa. Njira yapadera yochitira zinthu imapangitsa kuti zikhale zovuta kuti zinthu ziwiri zomwe zimagwira ntchito zikhale zovuta, ndipo mankhwalawa amakhala ndi moyo wautali
Mayesero awonetsa kuti Cyazofamizol+Cymoxan ili ndi zotsatira zabwino zofulumira komanso zokhalitsa pa choipitsa chochedwa, chomwe chimaposa mankhwala ena. Ngakhale matenda ambiri, amatha kuchiza komanso kuteteza. Ndiwo chida chakupha popewa komanso kuchiza choipitsa mochedwa.
