Abalimi abaninzi baye bafumana i-phytotoxicity xa besebenzisa i-mancozeb ngenxa yokukhetha ngokungafanelekanga imveliso okanye ukufakwa kwexesha elingachanekanga, idosi kunye nezihlandlo. Iimeko ezingephi zikhokelela kumonakalo wamagqabi, iphotosynthesis ebuthathaka, kunye nokungakhuli kakuhle kwesityalo. Kwiimeko ezimandundu, amachokoza amdaka (amachokoza amdaka, amachokoza atyheli, amachokoza omnatha, njl. njl.) akhula kumphezulu wesiqhamo kunye nomphezulu wamagqabi, kwaye abangele amachaphaza eziqhamo, umphezulu weziqhamo ezirhabaxa, kunye nomhlwa weziqhamo, nto leyo echaphazela kakhulu ixabiso lentengiso yesiqhamo, nto leyo ebangela ilahleko enkulu kumafama. Ngesishwankathelo, kufunyenwe ukuba izizathu eziphambili ze-phytotoxicity zezi zilandelayo:
1. Iimveliso ze-mancozeb ezingafanelekanga zikhokelela kwiziganeko eziphezulu ze-phytotoxicity.
I-mancozeb efanelekayo kufuneka ibe yi-manganese-zinc complex yemancozeb acideveliswa yinkqubo yokudibanisa i-thermal. Kukho amashishini amancinci kunye nabenzi bomgunyathi emarikeni abamveliso yabo ayinakubizwa ngokuba yi-mancozeb ngokwenyani. Ngenxa yokuthintelwa kwezixhobo zemveliso kunye neteknoloji, kuphela inxalenye encinci yeemveliso zala mashishini amancinci anokuthi adityaniswe kwi-mancozeb, kwaye uninzi luyimixube ye-mancozeb kunye neetyuwa ze-zinc. Ezi mveliso zinombala ongacacanga, umxholo wokungcola okuphezulu, kwaye zivame ukuthotywa xa zibonakaliswe kumswakama kunye nobushushu. Ukusebenzisa ezi mveliso kunokwenzeka ukuba kubangele i-phytotoxicity. Umzekelo, ukusebenzisa i-inferior mancozeb ngexesha lesiqhamo esincinci sama-apile kunokuchaphazela ukugalelwa kwe-wax kumphezulu wesiqhamo, kubangele umonakalo kwi- peel yesiqhamo kwaye kubangele amabala ajikelezayo e-phytotoxicity, athi ayanda njengoko isiqhamo sikhula.
2. Ukuxutywa ngobumfama kwezibulali-zinambuzane kuchaphazela ukhuseleko lokusetyenziswa kwe-mancozeb.
Xa uxuba i-pesticides, iinkalo ezininzi ezifana nezithako ezisebenzayo, iipropati zomzimba kunye neekhemikhali, iziphumo zokulawula, kunye nezinambuzane ezijoliswe kuzo kufuneka ziqwalaselwe. Ukuxuba okungaboniyo akugcini nje ukunciphisa ukusebenza kodwa kwandisa umngcipheko we-phytotoxicity. Umzekelo, isiko eliqhelekileyo lokuxuba i-mancozeb kunye nezibulali-zinambuzane zealkaline okanye iikhompawundi zentsimbi enzima ezinobhedu zinokunciphisa ukusebenza kwe-mancozeb. Ukudibanisa i-mancozeb kunye neemveliso ze-phosphate kunokukhokelela ekwakhekeni kwe-flocculent precipitates kunye nokukhutshwa kwegesi ye-hydrogen sulfide.
3. Ukukhetha okungafanelekanga kwexesha lokutshiza kunye nokulungelelaniswa ngokungaqhelekanga kokugxilwa kokutshiza kwandisa umngcipheko we-phytotoxicity.
Kusetyenziso lokwenyani, amafama amaninzi athanda ukunciphisa umlinganiselo wedilution ukuya kugxininiso oluchazwe kwimiyalelo okanye asebenzise ugxininiso oluphezulu kakhulu kunolucetyiswayo ukuze kwandiswe ukusebenza kakuhle. Oku kwandisa umngcipheko we-phytotoxicity. Kwangaxeshanye, amafama axuba amayeza okubulala izitshabalalisi amaninzi eempembelelo ze-synergistic, enikela ingqalelo kuphela kumagama ahlukeneyo orhwebo kodwa angahoyi izithako ezisebenzayo kunye neziqulatho zazo. Ngethuba lenkqubo yokuxuba, i-dosage yesithako esisebenzayo esifanayo siqokelela, kwaye ukuxinwa kwe-pesticide kwanda ngokungangqalanga, kudlula ukuxinwa okukhuselekileyo kwaye kubangela i-phytotoxicity. Ukusebenzisa izitshabalalisi phantsi kweemeko zobushushu obuphezulu kwandisa umsebenzi wokubulala izitshabalalisi. Ukutshiza i-pesticides ephezulu yokuxilisa kwandisa umngcipheko we-phytotoxicity.
4. Umgangatho wemveliso uchaphazela ukhuseleko lwe-mancozeb.
Ukucoleka, izinga lokunqunyanyiswa, ipropati yokumanzisa, kunye nokuncamathela kwamasuntswana e-mancozeb kuchaphazela ukusebenza kunye nokhuseleko lwemveliso. Iimveliso ze-mancozeb zamanye amashishini zineziphene kwizalathisi zobugcisa ezifana nokucolwa, izinga lokunqunyanyiswa, kunye nepropathi yokumanzisa ngenxa yonyino lwenkqubo yemveliso. Ngexesha lokusetyenziswa kwangempela, into eqhelekileyo yokubeka izitshabalalisi kunye nentlenga evalela umbhobho ixhaphakile. I-sedimentation ye-pesticide ngexesha lokutshiza ibangela ukugxininiswa okungahambelaniyo ngexesha lenkqubo yokutshiza, okubangelwa ukungasebenzi ngokwaneleyo kwiindawo eziphantsi kunye ne-phytotoxicity kwiindawo eziphezulu. Ukubambelela kakubi kwe-pesticide, kudityaniswe nomthamo omkhulu wamanzi asetyenziselwa ukutshiza, kubangela ukuba i-pesticide ingasasazeki kakuhle kwi-surface yamagqabi, ekhokelela ekuqokeleleni isisombululo se-pesticide kwiincam zamagqabi kunye nesiqhamo seziqhamo, okubangela ukugxila okuphezulu kwendawo kunye namabala e-phytotoxicity.
