Nahisemo kugerageza fungiside kuri soya kunshuro yambere uyu mwaka.Nabwirwa n'iki fungiside yo kugerageza, kandi ni ryari ngomba kuyikoresha?Nabwirwa n'iki ko bifasha?
Itsinda ryabajyanama ba Indiana ryemerewe gusubiza iki kibazo ririmo Betsy Bower, Ceres Solutions, Lafayette;Jamie Bultemeier, agronome, A&L Laboratoire y'Ibiyaga Bigari, Fort Wayne;na Andy Nk, umuhinzi na CCA, Vincennes.
Bower: Reba guhitamo ibicuruzwa bya fungiside hamwe nuburyo buvanze bwibikorwa bizaba birimo byibuze triazole na strobiluron.Bamwe barimo kandi ibikoresho bishya bya SDHI.Hitamo kimwe gifite ibikorwa byiza kumababi ya frogeye.
Hano hari ibihe bitatu bya soya abantu benshi baganira.Buri gihe kigira ibyiza byacyo nibibi.Iyaba nari shyashya gukoresha soya ya fungiside ya soya, nashakaga icyiciro cya R3, mugihe udusimba dutangiye kuboneka.Kuri iki cyiciro, urabona ubwirinzi bwiza kumababi menshi muri kanopi.
Porogaramu ya R4 yatinze cyane mumikino ariko irashobora kuba ingirakamaro cyane mugihe dufite umwaka windwara nke.Ku nshuro yambere ukoresha fungiside, ngira ngo R2, indabyo zuzuye, ni kare cyane kugirango ushire fungiside.
Inzira yonyine yo kumenya niba fungiside itezimbere umusaruro ni ugushyiramo igenzura ridafite porogaramu mu murima.Ntukoreshe umurongo wanyuma kugirango ugenzure neza, kandi urebe neza ko ukora ubugari bwumugozi wiburiburi byibuze ubunini bwumutwe wa kombine cyangwa uruziga.
Mugihe uhitamo fungicide, wibande kubicuruzwa bitanga kugenzura indwara wahuye nazo mumyaka yashize mugihe wasaka umurima wawe mbere no mugihe cyo kuzuza ingano.Niba ayo makuru adahari, reba ibicuruzwa byagutse bitanga uburyo burenze bumwe bwibikorwa.
Bultemeier: Ubushakashatsi bwerekana ko inyungu nini ku ishoramari ryo gukoresha imiti imwe ya fungiside kuva mu mpera za R2 kugeza hakiri kare R3.Tangira gushakisha imirima ya soya byibura buri cyumweru utangire kumera.Wibande ku ndwara n’umuvuduko w’udukoko kimwe nintambwe yo gukura kugirango umenye neza igihe cyo gukoresha fungiside.R3 izwi mugihe hari podo ya 3/16 kuri imwe murwego rwo hejuru.Niba indwara nkibibabi byera cyangwa frogeye ibibabi bigaragara, ushobora gukenera kuvura mbere ya R3.Niba ubuvuzi bubaye mbere ya R3, porogaramu ya kabiri irashobora gukenerwa nyuma yo kuzuza ingano.Niba ubonye aphide ya soya ikomeye, impumuro nziza, inyenzi zamababi yibishyimbo cyangwa inyenzi zo mubuyapani, kongeramo imiti yica udukoko mubisabwa birashobora kuba byiza.
Witondere gusiga cheque itavuwe kugirango umusaruro ugereranwe.
Komeza gushakisha umurima nyuma yo kubisaba, wibande ku itandukaniro ryumuvuduko windwara hagati yibice bivuwe kandi bitavuwe.Kugirango fungiside zitange umusaruro wiyongere, hagomba kubaho indwara zihari kugirango fungiside irinde.Gereranya umusaruro kuruhande hagati yavuwe kandi itavuwe mubice byinshi byumurima.
Kanda: Mubisanzwe, gukoresha fungiside hafi ya R3 yo gukura itanga umusaruro mwiza.Kumenya fungiside nziza yo gukoresha mbere yuko indwara itangira birashobora kugorana.Mubunararibonye bwanjye, fungicide ifite uburyo bubiri bwibikorwa hamwe nu rwego rwo hejuru ku kibabi cya frogeye cyakoze neza.Kubera ko ari umwaka wawe wambere hamwe na soya ya fungicide, nasiga imirongo mike yo kugenzura cyangwa gutandukanya imirima kugirango menye imikorere yibicuruzwa.
