Bikunze gukoreshwa mu kugabanya ibyago byo gucumbika mu bihingwa bitoshye, abashinzwe imikurire y’ibihingwa (PGRs) nacyo ni igikoresho cyingenzi gifasha imizi no gucunga guhinga mu bihingwa by’ibinyampeke.
Kandi iyi mpeshyi, aho ibihingwa byinshi bigora nyuma yubukonje bwinshi, ni urugero rwiza rwigihe abahinzi bazungukirwa no gukoresha neza ibicuruzwa.
Umuyobozi ushinzwe tekinike muri Hutchinsons, Dick Neale agira ati: “Ibihingwa by'ingano biri hirya no hino muri uyu mwaka.
Ati: "Ibihingwa byose byacukuwe kugeza muri Nzeri no mu ntangiriro z'Ukwakira birashoboka ko byafatwa nk'ibisanzwe muri gahunda yabo ya PGR, hibandwa ku kugabanya amacumbi."
Bikunze gutekerezwa ko PGR irema abahinzi benshi, ariko sibyo.Abahinzi bahujwe no gutanga amababi kandi ibyo bifitanye isano nigihe cyumuriro nkuko Bwana Neale abitangaza.
Niba ibihingwa bidacukuwe kugeza mu Gushyingo, bikagaragara neza mu Kuboza, bifite igihe gito cyo gushyushya amababi no guhinga.
Nubwo nta nteguza yo gukura izongera umubare w abahinzi ku gihingwa, irashobora gukoreshwa ifatanije na azote hakiri kare mu rwego rwo kubungabunga abahinzi benshi nubwo basarura.
Na none, niba ibimera bifite amababi ya tiller yiteguye guturika, PGR irashobora gukoreshwa kugirango ishishikarize gukura kwabo ariko mugihe gusa iyo tiller ihari.
Uburyo bwiza cyane bwo kubikora nukuringaniza abahinzi mukurwanya kwigenga no gushiraho imizi myinshi, ibyo PGR ishobora gukoreshwa mugihe ikoreshejwe hakiri kare (mbere yicyiciro cya 31).
Nyamara, PGR nyinshi ntishobora gukoreshwa mbere yicyiciro cya 30 cyiterambere, itanga inama Bwana Neale, bityo rero reba ibyemezo kuri label.
Kuri sayiri kora kimwe ningano murwego rwo gukura 30, ariko witondere gukura gukura kubicuruzwa bimwe.Noneho kuri 31, dosiye ndende ya prohexadione cyangwa trinexapac-ethyl, ariko nta 3C cyangwa Cycocel.
Impamvu yabyo nuko sayiri ihora isubira inyuma ya Cycocel kandi ishobora gutera amacumbi menshi ukoresheje chlormequat.
Mr Neale noneho yahoraga arangiza sayiri yubukonje mugihe cyikura 39 hamwe nibicuruzwa bishingiye kuri acide 2-chloroethylphosphonic.
Ati: "Kuri iki cyiciro, sayiri iri kuri 50% gusa yuburebure bwayo bwa nyuma, niba rero hari iterambere ryinshi ryigihe cyanyuma, ushobora gufatwa."
Trinexapac-Ethyl igororotse igomba gukoreshwa kuri metero zirenga 100ml / ha kugirango habeho imikoreshereze myiza yabaturage bahinga, ariko ibi ntibizagenga iyaguka ryuruganda.
Muri icyo gihe, ibimera bikenera urugero rukomeye rwa azote kugirango abahinzi bakure, basunike kandi baringanize.
Bwana Neale avuga ko we ku giti cye atazakoresha chlormequat mu porogaramu ya mbere ya PGR tiller.
Kwimukira kumurongo wa kabiri ushyirwa mubikorwa bya PGR, abahinzi bagomba kureba cyane kugenzura imikurire yikura ryuruti.
Bwana Neale aragabisha ati: "Abahinzi bazakenera kwitonda muri uyu mwaka, kuko iyo ingano yatinze gukanguka ikangutse, izajya kujyayo."
Birashoboka cyane ko amababi atatu ashobora kugera kuntambwe ya 31 ntabwo ari 32, bityo abahinzi bazakenera kumenya neza ikibabi kigaragara mukiciro cya 31.
Gukoresha imvange murwego rwo gukura 31 bizemeza ko ibimera bifite imbaraga zumuti bitarenze kubigabanya.
Asobanura agira ati: "Nakoresha prohexadione, trinexapac-ethyl, cyangwa imvange hamwe na 1litre / ha ya chlormequat".
Gukoresha iyi porogaramu bizasobanura ko utarenze igihe kandi PGRs izagenga igihingwa nkuko cyateganijwe aho kugabanya.
Bwana Neale agira ati: "Kora ibicuruzwa bishingiye kuri acide 2 ya chloroethylphosphonic mu mufuka winyuma nubwo, kuko tudashobora kumenya neza icyo imikurire izakurikiraho."
Niba hakiri ubuhehere mu butaka kandi ikirere kirashyuha, hamwe niminsi myinshi ikura, ibihingwa byatinze bishobora kugenda.
Guhitamo gutinda-igihe kugirango ukemure ibyago byinshi byo gutura mu mizi niba hari ibihingwa bitinze gukura mubutaka butose
Bwana Neale aragabisha ati: "Icyakora, uko ibihe by'impeshyi byatera, ibihingwa bitinze gutinda bigiye kugira isahani ntoya."
Ikibazo gikomeye muri uyu mwaka ni ukurara mu mizi ntabwo ari icumbi, kuko ubutaka bumaze kumera nabi kandi bushobora gutanga inzira hafi yimizi.
Aha niho gutanga uruti n'imbaraga bizaba ngombwa, niyo mpamvu gushyira mu bikorwa ubwitonzi bwa PGRs aribyo byose Bwana Neale agira inama muri iki gihembwe.
Yatanze umuburo agira ati: “Ntutegereze urebe hanyuma ube umutwaro uremereye.”“Igenzura ry'imikurire y'ibihingwa ni byo rwose - kugabanya ibyatsi ntabwo ari yo ntego y'ibanze.”
Abahinzi bagomba gusuzuma no gutekereza kubijyanye nimirire ihagije munsi yikimera kugirango babashe kubungabunga no kubicunga icyarimwe.
Igenzura ryikura ryibimera (PGRs) ryibanda kumikorere ya hormone yibihingwa kandi birashobora gukoreshwa muguhuza iterambere ryigihingwa.
Hariho umubare wibice bitandukanye byimiti bigira ingaruka kubihingwa muburyo butandukanye kandi abahinzi bakeneye buri gihe kugenzura ikirango mbere yo gukoresha buri gicuruzwa.
