Ndigqibe ekubeni ndizame amayeza okukhunta kwiimbotyi zesoya okokuqala kulo nyaka. Ndingayazi njani ukuba ndizama yiphi imithi yokukhunta, kwaye ndifanele ndiyisebenzise nini? Ndingayazi njani ukuba iyanceda?
Iqela labacebisi bezityalo abaqinisekisiweyo base-Indiana abaphendula lo mbuzo liquka uBetsy Bower, uCeres Solutions, uLafayette; uJamie Bultemeier, ingcali yezolimo, i-A&L Great Lakes Lab, eFort Wayne; kunye no-Andy Like, umlimi kunye ne-CCA, eVincennes.
Bower: Khangela ukukhetha imveliso yefungicide eneendlela ezahlukeneyo zokusebenza eziza kuquka ubuncinane i-triazole kunye ne-strobiluron. Ezinye ziquka nesithako esitsha esisebenzayo i-SDHI. Khetha enye enomsebenzi omhle kwibala leqabunga le-frogeye.
Kukho amaxesha amathathu okukhula kweembotyi zesoya abantu abaninzi abawaxoxayo.Ixesha ngalinye linezibonelelo kunye neengxaki zalo.Ukuba bendisandula ukusebenzisa i-fungicide yesoya, bendiya kujolisa kwinqanaba le-R3, xa iipods ziqala ukwakheka. Kweli nqanaba, ufumana ukugquma okuhle kumagqabi amaninzi akwikhanopu.
Ukusetyenziswa kwe-R4 kusemva kwexesha kodwa kunokuba luncedo kakhulu ukuba sinonyaka wesifo esincinci. Kumsebenzisi we-fungicide okokuqala, ndicinga ukuba i-R2, eqhakaza ngokupheleleyo, isekutsha kakhulu ukusebenzisa i-fungicide.
Eyona ndlela yokwazi ukuba i-fungicide iyaphucuka na kukufaka umcu wokujonga ongafakwanga entsimini. Musa ukusebenzisa imigca yokugqibela kumcu wokujonga, kwaye qiniseka ukuba wenza ububanzi bomcu wokujonga ubuncinane bube bubukhulu bentloko yokudibanisa okanye i-combine round.
Xa ukhetha amayeza okubola, gxila kwiimveliso ezibonelela ngolawulo lwezifo oye wadibana nazo kwiminyaka edlulileyo xa uhlola amasimi akho ngaphambi nangexesha lokuzaliswa kwengqolowa. Ukuba olo lwazi alufumaneki, khangela imveliso ebanzi enika iindlela ezahlukeneyo zokusebenza.
I-Bultemeier: Uphando lubonisa ukuba imbuyekezo enkulu kutyalo-mali lokusetyenziswa kanye kwe-fungicide iphuma ekusetyenzisweni kwe-R2 ukuya ekuqaleni kwe-R3. Qala ukukhangela amasimi eembotyi ubuncinane ngeveki ukususela ekudubuleni. Gxila kwizifo kunye noxinzelelo lwezinambuzane kunye nenqanaba lokukhula ukuqinisekisa ukuba ixesha elifanelekileyo lokusetyenziswa kwe-fungicide. I-R3 iphawulwa xa kukho i-pod eyi-3/16-intshi kwenye yee-nodes ezine eziphezulu. Ukuba kuvela izifo ezifana ne-white mold okanye i-frogeye leaf spot, unokufuna ukunyanga ngaphambi kwe-R3. Ukuba unyango lwenzeka ngaphambi kwe-R3, ukusetyenziswa kwesibini kunokufuneka kamva ngexesha lokuzaliswa kwengqolowa. Ukuba ubona ii-aphids zesoya ezibalulekileyo, ii-stinkbugs, ii-bean leaf beetle okanye ii-Japanese beetle, ukongezwa kwesibulali-zinambuzane ekusetyenzisweni kunokucetyiswa.
Qiniseka ukuba ushiya itshekhi enganyangwanga ukuze i-yield ithelekiswe.
Qhubeka uhlola intsimi emva kokufaka, ugxile kumahluko kuxinzelelo lwesifo phakathi kweendawo ezinyangiweyo kunye neendawo ezinganyangwanga. Ukuze iifungicides zibonelele ngokwanda kwesivuno, kufuneka kubekho izifo ezikhoyo ukuze ifungicide ilawuleke. Thelekisa isivuno ecaleni kwelinye phakathi kweendawo ezinyangiweyo kunye neendawo ezinganyangwanga kwiindawo ezingaphezu kwesinye zentsimi.
Njengoku: Ngokwesiqhelo, ukusetyenziswa kwe-fungicide kwinqanaba lokukhula kwe-R3 kunika iziphumo ezilungileyo zesivuno. Ukwazi i-fungicide engcono kakhulu onokuyisebenzisa ngaphambi kokuqala kwesifo kunokuba nzima. Ngokwamava am, i-fungicides eneendlela ezimbini zokusebenza kunye nenqanaba eliphezulu kwi-frogeye leaf spot isebenze kakuhle. Ekubeni ingunyaka wakho wokuqala nge-fungicides yesoya, ndingashiya imicu embalwa yokujonga okanye amasimi ahlukeneyo ukuze ndibone ukusebenza kweemveliso.
