I-isopropylthiamide yefungicide, uhlobo olutsha oluhle kakhulu lwezinambuzane zokulawula i-powdery mildew kunye ne-grey mold

1. Ulwazi olusisiseko

Igama lesiTshayina: Isopropylthiamide

Igama lesiNgesi: i-isofetamid

Inombolo yokungena ye-CAS: 875915-78-9

Igama lekhemikhali: N – [1, 1 - dimethyl - 2 - (4 - isopropyl oxygen - i-tolyl esecaleni) i-ethyl] – 2 – ukuveliswa kweoksijini – 3 – i-methyl thiophene – 2 – i-formamide

Ifomula yemolekyuli: C20H25NO3S

Ifomula yolwakhiwo:

Ubunzima bemolekyuli: 359.48

Indlela yokusebenza: I-Isoprothiamide sisibulali-fungi se-SDHI esinesakhiwo se-thiophenamide. Sinokuthintela ukudluliselwa kwee-electron, sithintele imetabolism yamandla eebhaktheriya ezibangela izifo, sithintele ukukhula kwazo kwaye sikhokelela ekufeni ngokuthatha indawo ye-ubiquinone ngokupheleleyo okanye kancinci.

Okwesibini, ingcebiso yokuxuba

1. I-Isoprothiamide ixutywe ne-pentazolol. Kuye kwabhaliswa amayeza axutyiweyo kwamanye amazwe, afana ne-25.0% isoprothiamide +18.2% pentazolol, 6.10% isoprothiamide +15.18% pentazolol kunye ne-5.06% isoprothiamide +15.18% pentazolol.

2. Ulwakhiwo lwe-bactericidal oluqulethe i-isopropylthiamide kunye ne-cycloacylamide oluyilwe nguZhang Xian et al., olunokwakhiwa kwiindidi ezahlukeneyo zemixube, lunokuthintela kwaye lulawule i-crop grey mold, i-sclerotium, i-black star, i-powdery mildew kunye ne-brown spot.

3. Indibaniselwano ye-benzoylamide kunye ne-isoprothiamide ebulala iintsholongwane eyenziwe yi-CAI Danqun et al. inefuthe elihambelanayo kwi-cucumber downy mildew kunye ne-grey mold ngaphakathi koluhlu oluthile, nto leyo enceda ekunciphiseni umthamo wamayeza, ukunciphisa iindleko kunye nokulawula ungcoliseko lokusingqongileyo.

4. Indibaniselwano ye-isoprothiamide kunye ne-fluoxonil okanye i-pyrimethamine ebulala iintsholongwane eyenziwe nguGe Jiachen et al., isetyenziselwa kakhulu ukuthintela nokunyanga i-crop gray mold, enefuthe elicacileyo le-synergistic kunye ne-dose encinci.

5. Indibaniselwano ye-phenacyclozole kunye ne-isopropylthiamide ebulala iintsholongwane eyenziwe nguGe Jiachen et al. Indlela yokusebenza kunye nendawo yokusebenza kwezi nxalenye zimbini zahlukile, kwaye ukuxubana kwezi nxalenye zimbini kunceda ekulibaziseni ukuveliswa kokumelana neentsholongwane ezibangela izifo, kwaye kungasetyenziselwa ukuthintela nokulawula izifo zakuqala, i-downy mildew kunye ne-powdery mildew yemifuno, imithi yeziqhamo kunye nezityalo zasemasimini, njl. Uvavanyo lubonisa ukuba ukuxuba kunempembelelo ecacileyo yokusebenzisana ngaphakathi koluhlu oluthile.
