5.2 Kpekpeɖeŋunana ƒe dodokpɔ le dɔbiagbalẽvi nu

• Gbewutikewo:  tsɔ ɖekawɔwɔ kple drift control ɖo nɔƒe gbãtɔ → medium to coarse droplets.

• Fungicides/Insecticides:  doa dzidzɔ na aŋgba ƒe nutsyɔnu → tsitete siwo le titina va ɖo esiwo le sue.

• Foliar feed:  tsitete siwo sɔ; kpɔ pH kple tsi ƒe nyonyome dzi.

6) Tiatia nozzle nyuitɔ le dɔwɔwɔ nu

6.1 Nyametsotso kabakaba ƒe matriki

• Yaƒoƒo, drift‐sensitive: ya‐induction flat fan; boom si le anyime; PSI si sɔ gbɔ wu.

• Aŋgba siwo le kpekpem/siwo le tsitrenu: twin‐fan alo hollow cone; ɖo kpe agbɔsɔsɔme kple PPE dzi.

• Gbeƒãɖeɖe si le ʋuʋu ɖi: standard/low‐drift flat fan; 110° ƒe dzogoe; ɖo kpe edzi be woƒo ƒu ɖe wo nɔewo dzi.

• Gli ƒe fliwo / gadzraɖoƒewo: deflector/boomless; woɖo kpe swath dzi; ɖe duƒuƒu dzi kpɔtɔ na goawo.

• Ami si me tsi le: aɖaŋuɖoɖo siwo ku ɖe tsi si sina toa eme ŋu; ƒo asa na dzobibi; ɖo kpe rate dzi kple pans.

6.2 Dzogoe & lolome tiatia (se siwo woatsɔ awɔ dɔe) .

• Tia dzogoe si sɔ kple boom ƒe kɔkɔme si dzi woate ŋu aɖu.

• Upsize nozzle orifice na agbɔsɔsɔ si lolo wu PSI si gbɔ eme manɔmee.

• Ðe PSI ƒe lolome dzi kpɔtɔ alo nàkɔe ɖe dzi ne coverage le seɖoƒe (susu ƒe ʋuʋu).

7) Dzadzraɖo: kɔ eŋu, lé ŋku ɖe eŋu, eye nàɖɔlii

• Filters & strainers: sɔ mesh kple nozzle ƒe lolome; dzadzɛnyenye le dɔ ɖesiaɖe megbe.

• Nozzle wear: ne sisi dzi ɖe edzi ~ 10% tso spec, ɖɔli abe set ene.

• Dzadzɛnyenye dedie: de tsi kple brɔs falɛfalɛ; ƒo asa na pin kple ka.

• Spare set rotation: dzra spare set dzadzɛ ɖo be nàɖɔli le agblea me.

8) Dedienɔnɔ & sedziwɔwɔ ƒe gɔmedzenufiafiawo

• Wɔ ɖe mɔfiame siwo woŋlɔ ɖe edzi dzi hena tsitete ƒe lolome kple tsi ƒe agbɔsɔsɔme.

• De bubu buffer zones kple ya ƒe dzidzenuwo ŋu; ƒo asa na fesre siwo me dzoxɔxɔ le, siwo ƒu, eye ya ƒoa xlã wo.

• Zã PPE si sɔ; tsi tsi eye nàtsɔ rinseate aƒu gbe le nutoa me sewo nu.

• Dzra beléle na wo ŋuti nuŋlɔɖiwo kple dzidzedzekpɔkpɔ ŋuti nuŋlɔɖiwo ɖo.

• Cranking PSI for coverage → te orifice si lolo wu alo dzogoe bubu kpɔ.

• Boom si kɔkɔ akpa → dzia drift kple uneven overlap ɖe edzi.

• Aɖabaŋeŋe ƒu azɔlizɔzɔ ƒe duƒuƒu dzi → gbugbɔ ɖɔe ɖo na dɔwɔla ɖesiaɖe kple agba.

• Klɔƒe kple ka → gblẽa nu le aɖaŋuɖoɖowo ŋu; tsi + brɔs falɛfalɛ boŋ.

• Mesh si mesɔ o → dɔwuame siwo le sue akpa la sina; coarse akpa ɖea mɔ na clogs.
