Uhlobo lwe-fungicide

2.1 Impuphu (DP)
Ngesibulala-zinambuzane sokuqala nesigcwalisi esingenasici esixutshwe ngenani elithile, impushana echotshoziwe nesieved. Ngokujwayelekile isetshenziselwa ukufafaza okuyimpushana ekukhiqizeni.

2.2 Impushana emanzi (WP)
I-pesticide yasekuqaleni, i-filler kanye nenani elithile lezithasiselo, ngokulingana nokuxuba okugcwele nokuchotshozwa, ukuze kuzuzwe ukucoleka okuthile kwempushana. Ingasetshenziselwa ukufafaza.

2.3 I-Emulsion (EC)
Eyaziwa nangokuthi "emulsion". Ngesibulala-zinambuzane sokuqala ngokwengxenye ethile yezinyibilikisi eziphilayo kanye nama-emulsifiers ancibilike oketshezini olunamafutha asobala. Ingasetshenziselwa ukufafaza. I-emulsion kulula ukungena ku-epidermis yezinambuzane, ingcono kune-powder emanzi.

2.4 Okunamanzi (AS)
Ezinye izibulala-zinambuzane zincibilika kalula emanzini, futhi zingasetshenziswa namanzi ngaphandle kwezithasiselo. Njenge-crystalline lithosulfuric acid, i-insecticide kabili, njll.

2.5 Izinhlamvana (GR)
Kwenziwe ngokukhangisa inani elithile le-ejenti enezinhlayiya zenhlabathi, i-cinder, i-brick slag, isihlabathi. Ngokuvamile i-filler ne-pesticide kuchotshozwa ndawonye kube yimpushana ethile, engeza amanzi kanye ne-ejenti eyisizayo ukwenza ama-granules. Ingasakazwa ngesandla noma ngomshini.

2.6 I-ejenti yokumisa okwesikhashana (ukumiswa kwejeli) (SC)
Ukusetshenziswa kwe-ultra-micro-grinding emanzi, impushana yesibulala-zinambuzane ehlakazekile emanzini noma emafutheni kanye nama-surfactants, ukwakheka kokwakheka koketshezi okugelezayo kwe-viscous. I-ejenti yokumiswa exutshwe nanoma iyiphi ingxenye yamanzi ukuze incibilike, ilungele izindlela ezihlukahlukene zokufutha. Ngemva kokufafaza, ingonga u-20% ~50% wesibulala-zinambuzane sokuqala ngenxa yokumelana namanzi emvula.

2.7 I-Fumigant (FU)
Ukusetshenziswa kwama-ejenti aqinile ane-sulfuric acid, amanzi nezinye izinto ukuze asabele ukukhiqiza amagesi anobuthi, noma ukusetshenziswa kwama-agent aphansi abilayo amagesi anobuthi aguquguqukayo, ukufutheka ezindaweni ezivaliwe nakwezinye izindawo ezithile ukuze kubulawe izinambuzane namagciwane okulungiswa.

2.8 I-Aerosol (AE)
I-aerosol iyisisombululo sikawoyela esiwuketshezi noma esiqinile, ukusetshenziswa kokushisa noma amandla emishini, uketshezi oluhlakazekile ekumisweni okuqhubekayo kwamaconsi amancane emoyeni, lube i-aerosol.

Indlela ye-fungicides

3.1 Ithonya ekwakhekeni kweseli kanye nokusebenza

Ama-fungicides avimbela ukukhula nokukhiqizwa kabusha kwamabhaktheriya e-pathogenic ngokuthinta ukwakheka kwezindonga ze-fungal cell kanye ne-plasma membrane biosynthesis. Amanye ama-fungicides enza amangqamuzana e-pathogen angavikelwe ngokucekela phansi ukwakheka kodonga lwamaseli, okuholela ekugcineni ekufeni kwamangqamuzana.

3.2 Umthelela ekukhiqizweni kwamandla eselula

Ama-fungicides angaphazamisa inqubo yokukhiqiza amandla amagciwane ngokusebenzisa izindlela ezahlukahlukene. Isibonelo, amanye ama-fungicides avimbela i-glycolysis kanye ne-fatty acid β-oxidation, ukuze amagciwane angakwazi ukukhiqiza amandla ngokujwayelekile, okuholela ekufeni kwawo.

3.3 Ukuthinta ukuhlanganiswa kwezinto ze-metabolic kanye nemisebenzi yazo

Amanye ama-fungicides enza ngokuphazamisa ukuhlanganiswa kwama-nucleic acids fungal namaprotheni. Lezi zinqubo ze-metabolic zibalulekile ekukhuleni nasekukhiqizeni amagciwane; ngakho-ke, ngokuvimbela lezi zinqubo, ama-fungicides angakwazi ukulawula ngokuphumelelayo ukuvela nokusabalala kwezifo.

3.4 Ukugqugquzela ukuzilawula kwezitshalo

Amanye ama-fungicides awasebenzi nje kuphela kubhaktheriya we-pathogenic, kodwa futhi enza isitshalo ukuthi simelane nezifo. Lawa maphilisi okubulala isikhunta angenza izitshalo zikhiqize “izinto zamasosha omzimba” eziqondene ngqo namagciwane noma zihlanganyele ekusetshenzisweni komzimba ukuze zikhiqize izinto ezisebenzayo ngokumelene namagciwane, ngaleyo ndlela kwandise ukumelana kwesitshalo ezifweni.

Isiphetho

Ama-fungicides adlala indima ebalulekile kwezolimo zesimanje ngokulawula nokuvikela izifo zezitshalo ngezindlela ezahlukahlukene. Izinhlobo ezahlukahlukene zama-fungicides zinezici zazo ngokuya ngesakhiwo samakhemikhali, indlela yokusetshenziswa, izakhiwo zokuqhuba kanye nendlela yokwenza, okubenza basetshenziswe kabanzi ezinhlelweni ezahlukahlukene zezolimo. Ukukhethwa okunengqondo nokusetshenziswa kwezibulala-sikhunta kungathuthukisa ngempumelelo isivuno kanye nekhwalithi yezitshalo futhi kuqinisekise intuthuko esimeme yokukhiqizwa kwezolimo.

FAQ
