Isopropylthiamide, mtundu watsopano wabwino kwambiri wa mankhwala ophera tizilombo polimbana ndi powdery mildew ndi imvi.

1. Chidziwitso choyambira

Dzina lachi China: Isopropylthiamide

Dzina la Chingerezi: isofetamid

Nambala yolowera ya CAS: 875915-78-9

Dzina la mankhwala: N – [1, 1 - dimethyl - 2 - (4 - isopropyl oxygen - pafupi ndi tolyl) ethyl] – 2 – kupanga mpweya – 3 – methyl thiophene – 2 – formamide

Fomula ya maselo: C20H25NO3S

Fomula yopangira kapangidwe kake:

Kulemera kwa maselo: 359.48

Njira Yogwirira Ntchito: Isoprothiamide ndi mankhwala ophera fungicide a SDHI okhala ndi kapangidwe ka thiophenamide. Amatha kuletsa kusamutsa ma elekitironi, kuletsa kagayidwe ka mphamvu ka mabakiteriya opatsirana, kuletsa kukula kwawo ndi kubweretsa imfa mwa kutenga gawo lonse la ubiquinone.

Chachiwiri, malangizo osakaniza

1. Isoprothiamide imasakanizidwa ndi pentazolol. Mankhwala osiyanasiyana osakanikirana alembedwa kunja, monga 25.0% isoprothiamide +18.2% pentazolol, 6.10% isoprothiamide +15.18% pentazolol ndi 5.06% isoprothiamide +15.18% pentazolol.

2. Kapangidwe ka mabakiteriya komwe kali ndi isopropylthiamide ndi cycloacylamide komwe kanakhazikitsidwa ndi Zhang Xian et al., komwe kangapangidwe m'njira zosiyanasiyana, kamatha kupewa ndikuwongolera nkhungu ya imvi, sclerotium, nyenyezi yakuda, ufa wa ufa ndi malo a bulauni.

3. Kuphatikiza kwa benzoylamide ndi isoprothiamide komwe kunapangidwa ndi CAI Danqun et al. kumathandizira kwambiri pa nkhaka ya downy mildew ndi imvi mosiyanasiyana, zomwe zimathandiza kuchepetsa mlingo wa mankhwala, kuchepetsa ndalama komanso kuwongolera kuipitsa chilengedwe.

4. Kuphatikiza kwa mabakiteriya kwa isoprothiamide ndi fluoxonil kapena pyrimethamine komwe kunapangidwa ndi Ge Jiachen et al., kumagwiritsidwa ntchito makamaka popewa ndi kuchiza nkhungu ya imvi, ndi mphamvu yodziwikiratu yogwirizana komanso mlingo wochepa.

5. Kuphatikiza kwa phenacyclozole ndi isopropylthiamide komwe kumapha mabakiteriya komwe kunapangidwa ndi Ge Jiachen ndi anzake. Kagwiridwe kake ka ntchito ndi malo ogwirira ntchito a zigawo ziwirizi ndi osiyana, ndipo kusakaniza kwa zigawo ziwirizi kumathandiza kuchedwetsa kupanga kukana kwa mabakiteriya opatsirana, ndipo kungagwiritsidwe ntchito popewa ndikuwongolera matenda oyamba, downy mildew ndi powdery mildew ya ndiwo zamasamba, mitengo ya zipatso ndi mbewu zakumunda, ndi zina zotero. Mayesowa akuwonetsa kuti kusakaniza kumeneku kuli ndi mphamvu yogwirizana mkati mwa mtundu wina.
