I-Fluopicolide , i-picarbutrazox, i-dimethomorph… ngubani onokuba namandla aphambili ekuthinteleni nasekulawuleni izifo ze-oomycete?

Isifo se-Oomycete senzeka kwizityalo zemelon ezifana nekhukhamba, izityalo zesolanaceous ezifana neetumato kunye nepepile, kunye nezityalo zemifuno e-cruciferous ezifana nekhaphetshu yaseTshayina. i-blight, i-eggplant ye-tomato blight blight, imifuno Phytophthora Pythium ukubola kweengcambu kunye nokubola kwesiqu, njl. ukulawula.

Ngokweenkcukacha-manani, imichiza yokungunda i-oomycete okwangoku ithatha malunga ne-20% yesabelo sangoku semarike yesichiza sokungunda, kwaye ngokuphuculwa okuqhubekayo kwinqanaba lemveliso yorhwebo yeemveliso zezolimo, imfuno yothintelo lwemichiza kunye nolawulo lwezifo ze-oomycete iya kwanda. Ukubaluleka kwemichiza yokungunda. Okwangoku, iiarhente zolawulo eziqhele ukusetyenziswa kwimarike ezineziphumo ezibalaseleyo yifluthiazolidinone, fluorobacillus propamocarb, mandipropamid, pyrimidine tetrazole, dimethomorph, flumorph, kunye necyanocream. I-Azole, i-cymoxanil, njl.

I-Picarbutrazox

I-Picarbutrazox yaphuhliswa kwaye yathengiswa yiNippon Soda. Ngomhla we-2 kuSeptemba, i-2021, i-Pesticide Control Institute yeSebe lezoLimo kunye neMicimbi yaseMaphandleni yelizwe lam yavuma ukubhaliswa kwe-97% pyrimidine tetrazolate technical (PD20211350) kunye ne-Picarbutrazox 10% SC (PD20211363) yaseJapan Soda Co., Ltd. ilizwe lam. Igama lokurhweba le-10% picarbutrazoxsuspension concentrate yi-Bixiluo®, ebhaliselwe ukulawula i-cucumber downy mildew. I-Lomton yaseTshayina yi-arhente eqhelekileyo yeemveliso ze-Bixiluo® e-China, kwaye inoxanduva olupheleleyo lokurhweba kunye nokuveliswa kwale mveliso e-China. Ukunyuswa kweBrand.

I-Picarbutrazox yi-carbamate fungicide enesakhiwo esisodwa sekhemikhali kunye nendlela entsha yokusebenza. Iyakwazi ukulawula ngokufanelekileyo izifo ezibangelwa yi-oomycetes, ezifana ne-downy mildew, i-Pythium, i-pseudoperonospermum kunye ne-Phytophthora, njl. I-Picarbutrazox ikwasisixhobo sokulawula ukuxhathisa kwaye ayinayo ukuchasana ne-carboxylic acid amides esetyenziswa ngokubanzi, i-phenylamides kunye ne-methoxyacrylate fungicides.

Idimethomorph

I-Dimethomorph yi-fungicide ethile kwi-oomycetes, isenzo sayo sibonakaliswe ngokutshabalalisa ukubunjwa kweembrane zodonga lweseli, kwaye ineempembelelo kuzo zonke izigaba zomjikelo wobomi be-oomycetes. I-Dimethomorph isetyenziswa kakhulu ukuthintela nokulawula izifo zokungunda, ezifana ne-downy mildew, i-downy mildew, i-late blight, blight, i-blackleg kunye nezinye izifo zezityalo, kwaye ingasetyenziselwa imithi yeziqhamo, imifuno kunye nezinye izityalo.

I-Diphenoxymorph i-prophylactic kwaye iyasebenza, kunye nomsebenzi oseleyo kumagqabi ezityalo, ukubonelela ngesenzo seprophylactic. Xa i-diphenoxymorph ifafazwe kwizityalo, iyeza lingangena kwi-tissue yeqabunga ngokusebenzisa umphezulu wamagqabi, kwaye ngokusasazwa, iqhube kwindawo yamagqabi, engasetyenziselwa ukukhusela nokulawula izifo zezityalo ezininzi ezibalulekileyo. Ezi ziquka cucumber downy mildew, grape downy mildew, iitapile late blight, tomato late blight, icuba black shank, nokunye. I-Diphenoxymorph ayinayo ukuchasana nomnqamlezo kunye ne-phenylamide fungicides esetyenziswa ngoku ngokubanzi (efana ne-metataxyl), kwaye inobudlelwane obuhle bamehlo. Isenokuxutywa nezinye iintlobo ezahlukeneyo zokubulala umngundo, njenge-mancozeb, njl.njl., ngokwenjenjalo Yandisa uluhlu lokuvala inzala kunye nomda wokusetyenziswa.

I-Cyazofamid+Cymoxanil

Amacandelo amabini eqabaka yecyanogen kunye neqabaka icyanogen ziikhompawundi ezimbini ze-downy mildew kunye ne-blight blight: i-frost pulse gas inokungena okunamandla kunye nokufunxa kwenkqubo, kwaye inokubonwa kwiiyure ezili-12 emva kokuba ibhaktheriya idibene ne-arhente. Umaleko wokungunda uqala ukoma: iqabaka yomoya inemisebenzi yonyango kunye nokukhusela, inokubulala ngokufanelekileyo iintsholongwane, kwaye inokubangela ukuba izityalo zivelise izilwa-buhlungu ezichasene ne-downy mildew kunye ne-blight emva kwexesha, ngoko ke inefuthe elihlala ixesha elide, elingcono kunezinye ii-arhente. ngokuchasene Ubude bexesha lezi zifo zikhankanywe ngasentla. Indlela ekhethekileyo yokusebenza yenza kube nzima ukuba izithako ezimbini ezisebenzayo ziphuhlise ukuchasana, kwaye imveliso inomjikelezo wobomi obude

Uvavanyo lubonise ukuba i-Cyazofamizol+Cymoxan ineempembelelo ezilungileyo ezikhawulezayo kunye nezihlala ixesha elide kwi-blight kade, engaphezulu kunezinye ii-arhente. Nokuba kwimeko yezifo ezininzi, inokunyanga kwaye ikhusele ngokufanelekileyo. Sesona sixhobo sokubulala ekuthinteleni nasekunyangelweni kobhubhani kade .
