Nahisemo kugerageza imiti yica udukoko kuri soya ku nshuro ya mbere uyu mwaka. Namenya nte imiti yica udukoko ngomba kugerageza, kandi ni ryari nkwiye kuyikoresha? Namenya nte niba ifasha?
Inama y’abajyanama b’ibihingwa bemewe na Indiana isubiza iki kibazo irimo Betsy Bower, Ceres Solutions, Lafayette; Jamie Bultemeier, impuguke mu by’ubuhinzi, A&L Great Lakes Lab, Fort Wayne; na Andy Like, umuhinzi akaba na CCA, Vincennes.
Bower: Reba uburyo bwo guhitamo umuti urwanya udukoko uvanze n'uburyo bwo gukora burimo nibura triazole na strobiluron. Harimo kandi ikintu gishya gikora SDHI. Hitamo kimwe gifite imikorere myiza ku gace k'ikibabi cya frogeye.
Hari ibihe bitatu byo guteka soya abantu benshi baganiraho.Buri gihe gifite ibyiza n'ibibi byacyo.Iyo nza kuba ndi mushya mu gukoresha umuti urwanya udukoko twa soya, nari kwibanda ku cyiciro cya R3, igihe udukoko dutangiye kumera. Muri iki cyiciro, uba utwikiriye neza amababi menshi ari mu gisenge.
Uburyo bwa R4 butinze cyane mu mukino ariko bushobora kugira akamaro cyane niba dufite umwaka urwaye. Ku muntu ukoresha imiti yica udukoko bwa mbere, ndatekereza ko R2, ifite indabyo nyinshi, ari kare cyane ku buryo umuntu atashobora gukoresha imiti yica udukoko.
Uburyo bwonyine bwo kumenya niba umuti wica udukoko urimo kwiyongera ni ugushyiramo agace k'umuti kadakoreshejwe mu murima. Ntugakoreshe imirongo y'impera ku gace k'umuti wawe, kandi menya neza ko ubugari bw'agace k'umuti bungana nibura n'umutwe w'umuti cyangwa umuti uzengurutse.
Mu guhitamo imiti yica udukoko, shyira imbaraga ku bicuruzwa bigabanya indwara wahuye na zo mu myaka ishize mu gihe ushakisha imirima yawe mbere no mu gihe cyo kuzuza ibinyampeke. Niba ayo makuru adahari, shakisha ibicuruzwa binini bitanga uburyo burenze bumwe bwo gukora.
Bultemeier: Ubushakashatsi bwerekana ko inyungu nini ku ishoramari ryo gukoresha imiti yica udukoko rimwe ituruka ku ikoreshwa rya R2 kugeza R3 mu ntangiriro. Tangira gusura imirima ya soya nibura buri cyumweru uhereye igihe itangiye kurabya. Ibande ku ndwara n'umuvuduko w'udukoko ndetse n'igihe cyo gukura kugira ngo umenye neza igihe cyo gukoresha imiti yica udukoko. R3 igaragara iyo hari agace ka santimetero 3/16 kuri imwe mu ngingo enye zo hejuru. Iyo indwara nk'ikibuno cyera cyangwa ikibabi cy'amababi ya frogeye bigaragaye, ushobora gukenera kuvura mbere ya R3. Iyo ubuvuzi bubaye mbere ya R3, ushobora kongera kuyikoresha nyuma mu gihe cy'izuba ryuzuye. Niba ubonye udukoko twinshi twa soya, udukoko duto, udukoko tw'amababi y'ibishyimbo cyangwa udukoko two mu Buyapani, kongeramo umuti wica udukoko mu ikoreshwa ryabyo bishobora kuba byiza.
Menya neza ko usigiye sheki idakozwe neza kugira ngo umusaruro ugereranywe.
Komeza urebe mu murima nyuma yo gukoresha imiti, wibanda ku itandukaniro ry'umuvuduko w'indwara hagati y'ibice byavuwe n'ibitaravuwe. Kugira ngo imiti yica udukoko itange umusaruro wiyongera, hagomba kubaho indwara kugira ngo imiti yica udukoko igenzure. Gereranya umusaruro uruhande ku rundi hagati y'imiti yavuwe n'iyitavuwe mu bice birenze kimwe by'umurima.
Nk'uko: Ubusanzwe, gukoresha imiti yica udukoko mu gihe cy'ikura rya R3 bitanga umusaruro mwiza. Kumenya imiti yica udukoko ikoreshwa mbere y'uko indwara itangira bishobora kugorana. Mu bunararibonye bwanjye, imiti yica udukoko ifite uburyo bubiri bwo gukora n'amanota yo hejuru kuri frogeye leaf spot yagenze neza. Kubera ko ari umwaka wawe wa mbere ukoresha imiti yica udukoko ya soya, nagusigira uduce duke two kugenzura cyangwa imirima igabanyijemo ibice kugira ngo umenye umusaruro w'ibikomoka ku bimera.
