I-Pesticide Adjuvants zizinto ezincedisayo ezongeziweyo ngexesha lokusetyenzwa okanye ukusetyenziswa kwemixube yesibulali-zinambuzane ukuphucula iimpawu zabo ze-physicochemical, ezaziwa ngokuba zizincedisi ze-pesticide. Ngelixa ama-adjuvants ngokwawo ngokubanzi engenawo umsebenzi webhayoloji, anokuba nefuthe elibonakalayo kulawulo lwezinambuzane ezitshabalalisayo. Ngokusetyenziswa ngokubanzi kunye nokuphuhliswa kwezincedisi ze-pesticide, iindidi zabo ziye zaqhubeka zanda, okwenza ukhetho lwe-adjuvant olufanelekileyo lube ngumngeni omkhulu wesibini kumafama emva kokukhetha isibulali-zinambuzane ngokwaso.

·Izigcwalisi kunye nabathwali
Ezi ziiminerali ezomeleleyo ezingasebenziyo, esekwe kwisityalo, okanye izinto ezenziweyo ezidityaniswe ngexesha lokusetyenzwa kwemixube eqinileyo yesibulali-zinambuzane ukulungisa ukuxinana kwemveliso yokugqibela okanye ukuphucula isimo sayo somzimba. Izihluzi zisetyenziselwa ukudibanisa isithako esisebenzayo kunye nokuphucula ukusasazwa kwayo, ngelixa abathwali bekwasebenza ukuthengisa okanye ukuthwala izinto ezisebenzayo. Imizekelo eqhelekileyo ibandakanya udongwe, umhlaba we-diatomaceous, i-kaolin, kunye nodongwe lobumba.
Izigcwalisi ziqhelekile ukuba zizinto ezingathathi hlangothi ezifana nodongwe, udongwe lodongwe, i-kaolin, umhlaba wediatomaceous, ipyrophyllite, kunye nomgubo wetalcum. Imisebenzi yabo ephambili kukunciphisa isithako esisebenzayo kunye nokuyibhengeza. Zisetyenziswa ikakhulu kwimveliso yomgubo, umgubo omanzi, iigranules, kunye neegranule ezihlakazeka amanzi. Indibaniselwano yangoku yesichumiso esithandwayo sesibulali-zinambuzane (okanye "izichumisi ezixutywe ngamayeza") sebenzisa izichumisi njengabathwali bezinambuzane ezibulala izinambuzane, ukudibanisa ezimbini ukuze kufezekiswe isicelo esidibeneyo.
Abathwali ayinyibilikisi kuphela isithako esisebenzayo kodwa ikwanceda ekuyibhengezeni, idlala indima ebalulekileyo kuzinzo kuqulunqo.
·Izinyibilikisi
Izinto eziphilayo ezisetyenziselwa ukunyibilikisa kunye nokunciphisa izithako ezisebenzayo ze-pesticides, ukuququzelela ukucubungula kunye nokusetyenziswa kwazo. Izinyibilikisi eziqhelekileyo ziquka ixylene, toluene, benzene, methanol, kunye nepetroleum ether. Zisetyenziswa ngokuyintloko ekuqulunqweni kwee-emulsifiable concentrates (EC). Iimfuno eziphambili ziquka amandla anamandla okunyibilika, ubutyhefu obuphantsi, i-flash point, ukungatsha, ixabiso eliphantsi, kunye nokufumaneka ngokubanzi.
·Emulsifiers
Ii-surfactants ezizinzisa ukusasazwa kolwelo olunye olungagungqiyo (umzekelo, i-oyile) ukuya kolunye (umzekelo, amanzi) njengamathontsi amancinane, zenza i-emulsion e-opaque okanye eyemi-opaque. Ezi zibizwa ngokuba zi-emulsifiers. Imizekelo eqhelekileyo ibandakanya i-polyoxyethylene-based esters okanye i-ethers (umzekelo, i-castor oil polyoxyethylene ether, i-alkylphenol polyethylene ether), ioli ebomvu yaseTurkey, kunye ne-sodium dilaurate diglyceride. Zisetyenziswa ngokubanzi kwi-concentrates emulsifiable, i-emulsion formulations yamanzi, kunye ne-microemulsions.
·Abasasaza
I-surfactants esetyenziselwa ukwakhiwa kwe-pesticide ukuthintela ukuhlanganiswa kwamasuntswana aqinileyo kwiinkqubo ze-slid-liquid dispersion systems, ziqinisekisa ukumiswa kwazo kwexesha elide kwi-liquid. Imizekelo ibandakanya i-sodium lignosulfonate kunye ne-NNO. Ngokuqhelekileyo zisetyenziselwa ukuveliswa kweempuphu ezimanzi, iigranules ezichithwa ngamanzi, kunye nokumiswa kwamanzi.
