Indlela yokwenza imichiza yokungunda

3.1 Impembelelo kulwakhiwo lweseli kunye nomsebenzi

Iifungicides zithintela ukukhula kunye nokuveliswa kwakhona kweebhaktheriya ze-pathogenic ngokuchaphazela ukubunjwa kweendonga zeeseli zefungal kunye ne-plasma membrane biosynthesis. Ezinye ii-fungicides zenza iiseli ze-pathogen zingakhuselekanga ngokutshabalalisa i-synthesis yodonga lweseli, olukhokelela ekugqibeleni ekufeni kweeseli.

3.2 Impembelelo kwimveliso yamandla eselula

I-fungicides inokuphazamisa inkqubo yokuvelisa amandla e-pathogens ngeendlela ezahlukeneyo. Ngokomzekelo, ezinye ii-fungicides zithintela i-glycolysis kunye ne-fatty acid β-oxidation, ukuze iintsholongwane zingakwazi ukuvelisa amandla ngokuqhelekileyo, nto leyo ekhokelela ekufeni kwabo.

3.3 Ukuchaphazela ukuhlanganiswa kwezinto ze-metabolic zeselula kunye nemisebenzi yazo

Eminye imichiza yokungunda isebenza ngokuphazamisana nokudityaniswa kwefungus nucleic acids kunye neeproteni. Ezi nkqubo zemetabolism zibalulekile ekukhuleni nasekuveliseni iintsholongwane; ngoko ke, ngokuthintela ezi nkqubo, imichiza yokungunda inokulawula ngokufanelekileyo ukwenzeka nokusasazeka kwezifo.

3.4 Ukukhuthaza ukuzilawula kwezityalo

Amachiza athile okubulala umngundo akasebenzi ngokuthe ngqo kwibhaktiriya ye-pathogenic kuphela, kodwa abangela ukuba isityalo simelane nezifo. Ezi zibulali zifo zokungunda zisenokwenza izityalo zivelise “amachiza” asebenza ngokuthe ngqo kwintsholongwane okanye athabathe inxaxheba kwimetabolism ukuvelisa izinto ezisebenza ngokuchasene nentsholongwane, ngaloo ndlela kwandisa ukuxhathisa kwesityalo kwizifo.

Ukuqukumbela

Imichiza yokungunda idlala indima ebalulekileyo kwezolimo zanamhlanje ngokulawula nokuthintela izifo zezityalo ngeendlela ezahlukeneyo. Iindidi ezahlukeneyo zefungicides zineempawu zazo ngokubhekiselele kwisakhiwo sekhemikhali, indlela yokusetyenziswa, iipropati zokuqhuba kunye nendlela yokwenza izinto, ezenza zisetyenziswe ngokubanzi kwizicelo ezahlukeneyo zezolimo. Ukukhethwa okunengqiqo kunye nokusetyenziswa kwefungicides kunokuphucula ngokufanelekileyo isivuno kunye nomgangatho wezityalo kunye nokuqinisekisa uphuhliso oluzinzileyo lwemveliso yezolimo.
