Engqungqutheleni emangalisayo embonini yezolimo,I-Trichloroisocyanuric Acid(TCCA), isibulali-magciwane esinamandla nesiguquguqukayo, muva nje sithole ukuqashelwa okuphawulekayo njengesibulali-magciwane esisebenza kahle kakhulu ezindaweni zokulima. Njengoba yasungulwa futhi yakhiqizwa ochwepheshe abaphambili kulo mkhakha, i-TCCA ivele njengesixazululo esishintsha umdlalo esisiza ukuvikela impilo nenhlalakahle yemfuyo, ngesikhathi esifanayo ibhekana nokukhathazeka okukhulu kwabalimi mayelana nokuphepha kwezinto eziphilayo kanye nokuvimbela izifo.
I-TCCA, etholakala ku-cyanuric acid futhi esetshenziswa kabanzi ezinqubweni zokubulala amagciwane, ibonakale iyithuluzi elibalulekile lokulwa namagciwane nokuqeda amagciwane ayingozi ezindaweni zokulima. Ukusebenza kwayo kulele ekhonweni layo lokubulala amagciwane ngokushesha ezindaweni, imishini, kanye nemithombo yamanzi, kunciphisa ngempumelelo ingozi yokudluliswa kwezifo kanye nokungcola. Lesi sixazululo esikhiqizwa efektri sokubulala amagciwane asisebenzi nje kuphela ngokushesha kodwa futhi sihlinzeka ngemiphumela ehlala isikhathi eside, sinikeza abalimi indlela ephelele neqhubekayo yokugcina indawo yokulima ephephile nenempilo.
Enye yezinzuzo ezibalulekile zokusebenzisa i-TCCA njengesibulali-magciwane umsebenzi wayo obanzi wokulwa nezinhlobo eziningi zezifo ezibangelwa amagciwane, okuhlanganisa amabhaktheriya, amagciwane, kanye nesikhunta. Leli khono elimangalisayo liqinisekisa ukubulala amagciwane okuphelele, okungashiyi ndawo yokusinda nokwanda kwamagciwane ayingozi angalimaza impilo yezilwane kanye nokukhiqiza. Ngaphezu kwalokho, ukuzinza kwe-TCCA kanye nokuphila isikhathi eside eshalofini kwenza kube ukukhetha okuhle kakhulu kwemisebenzi yokulima emikhulu, okuvumela abalimi ukuthi bathuthukise izinsiza zabo futhi banciphise izindleko ezihambisana nokubulala amagciwane njalo.
Ukwamukelwa kwe-Trichloroisocyanuric Acid njengesithako sokufutha ezindaweni zokulima kuye kwaletha ukuthuthuka okuphawulekayo empilweni nasekuphepheni kwemfuyo. Ngokusebenzisa izinqubo zokubulala amagciwane ezisekelwe ku-TCCA, abalimi babike ukwehla okukhulu kokuqubuka kwezifo, inhlalakahle yezilwane ethuthukisiwe, kanye nokukhiqiza okuthuthukisiwe. Lokhu kuphumelela akugcini nje ngokuguqula imikhuba yendabuko yokulima kodwa futhi kuhlinzeke ngenye indlela eqhubekayo nenobungani nemvelo kuneyendabuko.izibulali-magciwane zamakhemikhali.
Njengoba izindaba zisakazeka ngezinzuzo ezimangalisayo ze-TCCA, abalimi abaningi bayasamukela lesi sixazululo esisha ukuqinisekisa ukuphepha okuphezulu kwe-bioefektri emapulazini abo. Ngokuthuthuka okuqhubekayo kobuchwepheshe befektri yokubulala amagciwane, ukukhiqizwa kanye nokutholakala kwe-TCCA kulungele ukuhlangabezana nesidingo esikhulayo, okuqinisa isimo sayo njengesithako esisetshenziswa kakhulu ezindaweni zokulima emhlabeni jikelele.
Ekuphetheni, ukwanda kwe-Trichloroisocyanuric Acid njengesifutho esisebenzayo ezindaweni zokulima kuphawula ingqophamlando ebalulekile emkhakheni wezolimo. Ukusebenza kwayo okuqinisekisiwe, umsebenzi wayo obanzi, kanye nesimo sayo esiqhubekayo kushintshe indlela abalimi ababhekana ngayo nokuphepha kwezilwane kanye nokuvimbela izifo. Ngokufaka i-TCCA emikhubeni yabo yokubulala amagciwane, abalimi bathatha izinyathelo zokuthuthukisa impilo nokuphepha kwemfuyo, ukuqinisekisa uhlelo lokulima oluchumayo noluqhubekayo iminyaka ezayo.
