Impela kuwumlomo nje ukusho i-pyraclostrobin, kodwa kusho okuthile okubalulekile kubo bonke abalimi nabalimi bezingadi laphaya. Lolu uhlobo lwamakhemikhali oludlala indima ngokukhethekileyo njengesibulala-sikhunta. Ukusho lokhu, okubasiza ukuba bavikeleke ekuthelelekeni ngesikhunta futhi - halten sie sich fest! Kulo mbhalo, sizokhuluma ngokuthi iyini i-pyraclostrobin nokuthi isebenza kanjani ezitshalweni nakwezolimo ngokujwayelekile.
I-Pyraclostrobin iyikhemikhali eyodwa ye-strobilurins. Ngokuvamile kuba impushana emhlophe. Isetshenziswa abalimi nabalimi ukuyisakaza emaqabunga ezitshalo noma eziqwini zayo ukuze zihlale zivikelekile kunoma yiziphi izifo ezingonakalisa izitshalo zazo. I-BASF yinkampani kusukela ngo-1997 ekhiqize le khemikhali futhi manje lo mkhiqizo usetshenziswa emazweni ahlukene, emhlabeni jikelele ukunakekelwa kwezitshalo.
Kulabo abakhula izitshalo nezithelo ezinempilo, izifo zesikhunta yinkinga yazo enkulu. Lezo zifo ziyingozi ezitshalweni ezihlukahlukene, ngakho-ke kukhona zonke izizathu zokufuna izindlela zokuzivikela. Isikhunta siqoqa amaseli ezimpande zezitshalo, njengamacansi afana neshidi ku-biotrophic endophyte encane noma izakhiwo ze-microsclerotial zakudala kwamanye ama-biotrophic amaningi. Izinhlamvu zivame ukusabalala ngokushesha lapho impahla iniselwa, ithwalwa ngumoya futhi inhlabathi ngokwayo izobe isidlulisela amagciwane asuka ezitshalweni ezingumama aye kwezinye izitshalo ezisengozini ngokuhamba kwesikhathi. Uma lezi zinhlamvu zihlala kwesinye isitshalo, ziyaqhuma (ziqale ukukhula futhi zenze izitshalo zigule) futhi lokhu kungaba kubi kakhulu uma kwehla nezitshalo okubangela ukuncipha kwesivuno bese kuncipha ukutholakala kokudla.
I-Pyraclostrobin ivimbela lezi zifo ukuthi zenzeke ngokuphazamisa inqubo esetshenziswa isikhunta ukukhiqiza amandla. Amandla ayadingeka ukuze kubangele ukukhula kwesikhunta, Lapho isikhunta sithatha la mandla ngenqubo ebizwa ngokuthi ukuphefumula. I-Pyraclostrobin ivimbela ukukhiqizwa kwamandla esikhunta ngokuvimbela ukuphefumula. Ngaphandle kwamandla, isikhunta sizolamba futhi ngeke sizalane kwenye indawo.
I-Pyraclostrobin isibulala-sikhunta esibanzi esilwa nezinhlobo ezingaba ngu-20 zezifo zokukhunta ezitshalweni ezihlukahlukene. I-Copper iyasiza futhi ekwelapheni i-powdery mildew, ukugqwala kanye nesikhunta esimpunga. Lokhu kuvumela ukuthi ikhonze izinhlobo eziningi zezitshalo, njengezithelo zesihlahla njengama-apula namawolintshi; ukukhiqizwa kwemifino okuhlanganisa utamatisi kanye nolethisi; ukutshalwa kwezinhlamvu ngokokolo noma ummbila, kungashiyi ngaphandle ukutshalwa okuhle okuboniswa izimbali. Abalimi bangatshala ukudla okwengeziwe, futhi bondle labo abasezweni elisha nsuku zonke ngokugcina lezi zitshalo ziphilile ngosizo lwe-pyraclostrobin.
Kunezizathu eziningi zokuthi kungani abalimi nabalimi kufanele basebenzise i-pyraclostrobin. Ukuqala, kubasiza ukuthi batshale izilimo zabo. Isebenza ngokuvimbela izifo zesikhunta, ivumela abalimi ukuthi bakhiqize ukudla okwengeziwe kanye nomkhiqizo wekhwalithi ephezulu, okudingekile ngokuphelele ukupha abantu ukudla. Okwesibili, kulula ukuyisebenzisa. Abalimi bangawuxuba namanzi bese befafaza esitjalweni sabo, benze ukufaka isicelo kube lula.
Manje, kunezinto ezithile okufanele uziqaphele lapho usebenzisa i-pyraclostrobin Akusona isixazululo esiphelele. Isebenza ngokumelene nama-fungus amaningana, kodwa hhayi wonke. Abalimi bangase baphoqeleke ukuthi bafake amakhemikhali engeziwe ezindabeni zezitshalo ngazinye. Kubalimi, kubalulekile ukwazi ukuthi hlobo luni lwesikhunta ababhekene naso, ukuze bakwazi ukukhetha ukwelashwa okufanele.
Sihlala silindele ukubonisana kwakho.
