I-Chlorothalonil

I-Chlorothalonil kanye nesikhunta esivikelayo

I-Chlorothalonil ne-Mancozeb womabili ama-fungicides avikelayo aphuma ngeminyaka yawo-1960s futhi abikwa okokuqala ngu-TURNER NJ ekuqaleni kwawo-1960. I-Chlorothalonil yafakwa emakethe ngo-1963 yi-Diamond Alkali Co. (kamuva yadayiselwa i-ISK Biosciences Corp. yase-Japan) yabe isithengiswa ku-Zeneca Agrochemicals (manje eyi-Syngenta) ngo-1997. I-Chlorothalonil iwumuthi wokukhunta ovikelayo obanzi onezindawo eziningi zesenzo, ongasetshenziselwa ukuvimbela nokwelashwa kwezifo ezithinta utshani. Ukulungiswa kwe-chlorothalonil kwabhaliswa okokuqala e-United States ngo-1966 futhi kwasetshenziselwa utshani. Eminyakeni embalwa kamuva, yathola ukubhaliswa kwesibulala-sikhunta samazambane e-United States. Kwakuyisibulala-sikhunta sokuqala esigunyazwe izitshalo zokudla e-United States. Ngomhla zingama-24 kuZibandlela, 1980, umkhiqizo wokugxilisa ingqondo othuthukisiwe (i-Daconil 2787 Flowable Fungicide) wabhaliswa. Ngo-2002, umkhiqizo wotshani owawubhaliswe ngaphambilini i-Daconil 2787 W-75 TurfCare waphelelwa yisikhathi e-Canada, kodwa umkhiqizo wokugxilisa u-suspension usetshenziswa kuze kube namuhla. NgoJulayi 19, 2006, omunye umkhiqizo we-chlorothalonil, i-Daconil Ultrex, wabhaliswa okokuqala ngqa.

Izimakethe ezinhlanu eziphezulu ze-chlorothalonil zise-United States, France, China, Brazil nase-Japan. I-United States iyimakethe enkulu kunazo zonke. Izitshalo ezisetshenziswa kakhulu izithelo, imifino kanye nokusanhlamvu, amazambane, kanye nezicelo ezingezona izitshalo. Okusanhlamvu namazambane aseYurophu yizitshalo eziyinhloko ze-chlorothalonil.

Isibulali sikhunta esivikelayo sisho ukufafaza phezu kwesitshalo ngaphambi kokuba isifo sesitshalo sigweme ukuhlasela kwamagciwane, ukuze isitshalo sivikeleke. Ama-fungicides anjalo avikelayo athuthukiswa ngaphambili futhi asesetshenziswe isikhathi eside kakhulu.

I-Chlorothalonil iyisikhunta esine-spectrum esibanzi esinezindawo ezivikelayo ezinezenzo eziningi. Isetshenziselwa kakhulu ukufafaza ngamahlamvu ukuvimbela nokulawula izifo ezihlukahlukene zezitshalo ezihlukahlukene njengemifino, izihlahla zezithelo kanye nokolweni, njengokubola kwangaphambi kwesikhathi, ukubola okuphuzile, i-downy mildew, i-Powdery mildew, i-leaf spot, njll. Isebenza ngokuvimbela ukuhluma kwe-spore kanye nokunyakaza kwe-zoospore.

Ngaphezu kwalokho, i-chlorothalonil iphinde isetshenziswe njengesilondolozi sezinkuni kanye nesengezo sikapende (anti-corrosion).
