I-isopropylthiamide ye-fungicide, uhlobo olusha oluhle kakhulu lwe-pesticide lokulawula i-powdery mildew kanye ne-grey mold

1. Ulwazi oluyisisekelo

Igama lesiShayina: Isopropylthiamide

Igama lesiNgisi: i-isofetamid

Inombolo yokungena ye-CAS: 875915-78-9

Igama lamakhemikhali: N – [1, 1 - dimethyl - 2 - (4 - isopropyl oxygen - i-tolyl eseduze) i-ethyl] – 2 – ukukhiqizwa komoya-mpilo – 3 – i-methyl thiophene – 2 – i-formamide

Ifomula yama-molecule: C20H25NO3S

Ifomula yesakhiwo:

Isisindo sama-molecule: 359.48

Indlela yokusebenza: I-Isoprothiamide iyi-fungicide ye-SDHI enesakhiwo se-thiophenamide. Ingavimbela ukudluliselwa kwama-electron, ivimbele ukusetshenziswa kwamandla kwamagciwane abangela izifo, ivimbele ukukhula kwawo futhi iholele ekufeni ngokuthatha indawo ye-substrate ubiquinone ngokuphelele noma ngokwengxenye.

Okwesibili, isincomo sokuxuba

1. I-Isoprothiamide ixutshwe ne-pentazolol. Kubhaliswe amalungiselelo amaningana axubile kwamanye amazwe, njenge-25.0% isoprothiamide +18.2% pentazolol, 6.10% isoprothiamide +15.18% pentazolol kanye ne-5.06% isoprothiamide +15.18% pentazolol.

2. Ukwakheka kwamagciwane okuqukethe i-isopropylthiamide kanye ne-cycloacylamide okwasungulwa nguZhang Xian et al., okungakhiwa ngezindlela ezahlukahlukene, kungavimbela futhi kulawule isikhunta esimpunga, i-sclerotium, inkanyezi emnyama, isikhunta esimpunga kanye nebala elinsundu.

3. Inhlanganisela ye-benzoylamide ne-isoprothiamide ebulala amagciwane eyasungulwa yi-CAI Danqun nabanye. inomphumela wokubambisana ku-cucumber downy mildew kanye ne-grey mold ngaphakathi kobubanzi obuthile, okusiza ekunciphiseni umthamo wemithi, ukunciphisa izindleko kanye nokulawula ukungcola kwemvelo.

4. Inhlanganisela yamagciwane ye-isoprothiamide ne-fluoxonil noma i-pyrimethamine eyasungulwa nguGe Jiachen et al., isetshenziswa kakhulu ekuvimbeleni nasekwelapha isikhunta esimpunga, ngomphumela osobala wokubambisana kanye nomthamo omncane.

5. Inhlanganisela ye-phenacyclozole kanye ne-isopropylthiamide ebulala amagciwane eyasungulwa nguGe Jiachen nabanye. Indlela yokusebenza kanye nendawo yokusebenza kwezingxenye ezimbili kuhlukile, futhi ukuxuba izingxenye ezimbili kusiza ekubambezeleni ukukhiqizwa kokumelana kwamagciwane abangela izifo, futhi kungasetshenziswa ukuvimbela nokulawula izifo zakuqala, i-downy mildew kanye ne-powdery mildew yemifino, izihlahla zezithelo kanye nezitshalo zasensimini, njll. Ukuhlolwa kukhombisa ukuthi ukuxuba kunomphumela ocacile wokubambisana ngaphakathi kobubanzi obuthile.
