Isifo i-Oomycete senzeka ezitshalweni ze-melon ezifana nokhukhamba, izitshalo ze-solanaceous ezifana notamatisi nopelepele, kanye nezitshalo zemifino e-cruciferous ezifana neklabishi laseShayina. i-blight, i-eggplant tomato ka-cotton blight, imifino I-Phytophthora Pythium izimpande kanye nokubola kwesiqu, njll. Ngenxa yobuningi bamagciwane omhlaba, ukufihlwa kwamagciwane omhlaba, nokungaqiniseki kokudluliselwa kwe-pathogen emoyeni, ekukhiqizeni kwangempela, izifo ze-oomycete zinzima kakhulu. ukulawula.
Ngokwezibalo, ama-oomycete fungicides njengamanje athatha cishe u-20% wesabelo semakethe somuthi wokubulala isikhunta, futhi ngokuthuthukiswa okuqhubekayo kwezinga lokukhiqizwa kwezentengiselwano lemikhiqizo yezolimo, isidingo sokuvimbela amakhemikhali nokulawulwa kwezifo ze-oomycete sizokhula. Ukubaluleka kwama-fungicides. Njengamanje, ama-ejenti okulawula asetshenziswa kakhulu emakethe anemiphumela evelele i-fluthiazolidinone, i-fluorobacillus propamocarb, i-mandipropamid, i-pyrimidine tetrazole, i-dimethomorph, i-flumorph, ne-cyanocream. I-Azole, i-cymoxanil, njll.
I-Picarbutrazox
I-Picarbutrazox yasungulwa futhi imakethwa ngabakwaNippon Soda. NgoSepthemba 2, 2021, Isikhungo Sokulawulwa Kwezinambuzane Zomnyango Wezolimo Nezindaba Zasemakhaya wezwe lami sagunyaza ukubhaliswa kwe-97% pyrimidine tetrazolate technical (PD20211350) kanye ne-Picarbutrazox 10% SC (PD20211363) yaseJapan Soda Co., Ltd. izwe lami. Igama lokuhweba lika-10% picarbutrazoxsuspension concentrate yi-Bixiluo®, ebhaliselwe ukulawula i-cucumber downy mildew. I-Lomton China iyi-ejenti ejwayelekile ekhethekile yemikhiqizo ye-Bixiluo® e-China, futhi inesibopho esigcwele sokuthengisa nokukhiqizwa kwalo mkhiqizo e-China. Ukukhuthazwa Komkhiqizo.
I-Picarbutrazox iyi-carbamate fungicide enesakhiwo samakhemikhali esiyingqayizivele kanye nendlela entsha yokusebenza. Ingakwazi ukulawula ngempumelelo izifo ezibangelwa i-oomycetes, njenge-downy mildew, i-Pythium, i-pseudoperonospermum ne-Phytophthora, njll. I-Picarbutrazox futhi iyithuluzi lokulawula ukumelana futhi ayinakho ukumelana ne-carboxylic acid amide esetshenziswa kabanzi, ama-phenylamide kanye nama-fungicides e-methoxyacrylate.
I-Dimethomorph
I-Dimethomorph iyi-fungicide eqondene ne-oomycetes, isenzo sayo sibonakala ngokucekela phansi ukwakheka kwamangqamuzana odonga lwamaseli, futhi inemiphumela kuzo zonke izigaba zomjikelezo wokuphila we-oomycetes. I-Dimethomorph isetshenziselwa kakhulu ukuvimbela nokulawula izifo zesikhunta, ezifana ne-downy mildew, i-downy mildew, i-late blight, i-blight, i-blackleg nezinye izifo zezitshalo, futhi ingasetshenziselwa izihlahla zezithelo, imifino kanye nezinye izitshalo.
I-Diphenoxymorph iyi-prophylactic futhi iyasebenza, inomsebenzi oyinsalela emaqabunga ezitshalo, ihlinzeka ngesenzo sokuvimbela. Lapho i-diphenoxymorph ifafazwa ezitshalweni, umuthi ungangena esicutshini samaqabunga ngokusebenzisa amaqabunga, futhi ngokusakazwa, uqhube endaweni emaqabunga, angasetshenziswa ukuvimbela nokulawula izifo zezitshalo eziningi ezibalulekile. Lezi zihlanganisa i-cucumber downy mildew, i-grape downy mildew, i-potato late blight, i-tomato late blight, i-cuba black shank nokunye. I-Diphenoxymorph ayinakho ukumelana nemithi esetshenziswa kabanzi manje ye-phenylamide fungicides (njenge-metataxyl), futhi inokusondelana okuhle kwamehlo. Ingaxutshwa nezinye izinhlobo ezihlukene zokubulala isikhunta, njenge-mancozeb, njll., ngaleyo ndlela Nweba i-spectrum yokuvala inzalo kanye nobubanzi bokusetshenziswa.
I-Cyazofamid+Cymoxanil
Izingxenye ezimbili ze-cyanogen frost kanye ne-frost gland cyanogen yizici ezimbili ezihlanganisa i-downy mildew kanye nokulimaza sekwephuzile: i-frost pulse gas inokungeneka okuqinile kanye nokumuncwa kwesistimu, futhi ingabonwa emahoreni ayi-12 ngemva kokuba amagciwane ethinte i-ejenti. Ungqimba lwesikhunta luqala ukoma: isithwathwa somoya sinemisebenzi yokwelapha neyokuvikela, singabulala amagciwane ngokuphumelelayo, futhi singenza izitshalo zikhiqize amasosha omzimba alwa ne-downy mildew kanye ne-blight sekwephuzile, ngakho-ke kuba nomthelela ohlala isikhathi eside, ongcono kunamanye ama-ejenti. ngokumelene Ubude besikhathi sezifo ezibalwe ngenhla. Indlela yokusebenza eyingqayizivele yenza kube nzima ukuthi izithako ezimbili ezisebenzayo zithuthukise ukumelana, futhi umkhiqizo unomjikelezo wempilo ende
Ukuhlola kubonise ukuthi i-Cyazofamizol+Cymoxan inemiphumela emihle esheshayo nehlala isikhathi eside ekubhujisweni sekwephuzile, okungaphezu kwamanye ama-ejenti. Ngisho nenani elikhulu lezifo, lingaphatha futhi livikele ngempumelelo. Kuyisikhali esibulalayo ekuvimbeleni nasekwelapheni okulimazayo sekwephuzile.
