Iifungicides

I-fungicides luhlobo lwesitshabalalisi esisetyenziselwa ukulawula izifo zezityalo ezibangelwa yi-pathogenic microorganisms ezahlukeneyo.Imichiza yokungunda yahlulwe yazizichiza zokungunda ezingaphiliyo kunye nezibulala-zinambuzane eziphilayo ngokusekelwe kwimichiza yazo.Zintathu iindidi zokubulala ukungunda okungaphiliyo: imichiza yesulphur, imichiza yokungunda yobhedu, nemichiza yokungunda imekyuri;Imichiza yokungunda ephilayo inokohlulwa ibe yisulfure ephilayo (efana ne mancozeb), trichloromethyl sulfide (efana ne captan), endaweni ye benzene (efana ne Chlorothalonil), ipyrrole (efana nokunxitywa kwembewu), iorganic phosphorus (njenge aluminium ethophosphate), iBenzimidazole (enjalo njengeCarbendazim), i-triazole (njenge-triadimefon, i-triadimenol), i-phenylamide (njenge-metaxyl), njl.

Ngokwezinto zokuthintela kunye nokunyanga, Inokwahlulwa ibe yi-Fungicide, bactericides, virus killers, njl njl.

Ngokomthombo wezinto eziluhlaza, inokohlulwa ibe yimichiza yokwenziwa kwemichiza yokungunda, amayeza okubulala iintsholongwane ezolimo (afana nejinggangmycin, amayeza okubulala umngundo 120), amayeza okubulala umngundo, isityalo seDefensin, njl. imichiza yokungunda.Ngokomzekelo, i-chlorine, i-Sodium hypochlorite, i-bromine, i-ozone kunye ne-chloramine ziyi-bactericides oxidizing;I-quaternary ammonium cation, i-dithiocyanomethane, njl.

1. Izilumkiso zokusebenzisa imichiza yokungundaXa ukhetha imichiza yokungunda, kubalulekile ukuqonda iimpawu zazo.Kukho iintlobo ezimbini zemichiza yokungunda, enye yi-agent ekhuselayo, esetyenziselwa ukuthintela izifo zezityalo, ezifana ne-Bordeaux mix liquid, i-mancozeb, i-Carbendazim, njl.Olunye uhlobo zii-agent zonyango, ezisetyenziswa emva kokuqala kwesifo sezityalo ukubulala okanye ukuvimbela iibhaktheriya ze-pathogenic ezihlasela umzimba wesityalo.Ii-arhente zonyango zineziphumo ezilungileyo kwizigaba zokuqala zesifo, ezifana ne-fungicides edibeneyo efana ne-Kangkuning kunye ne-Baozhida.
