Kugwiritsa ntchito mankhwala a herbicides koyambirira kumatha kuwongolera bwino mbewu za dzinja

Kumera kusanachitike ndi njira yabwino yothanirana ndi udzu mu dzinja la dzinja.Komabe, chifukwa alimi amayang'ana kwambiri kubzala nyengo ikalola, sizitheka nthawi zonse.
Komabe, mvula yomwe idagwa sabata ino idaletsa anthu ambiri kubzala, ndipo omwe adabzala amatha kusunthira sprayer kwina ngati nthaka ili yabwino.Kupopera mankhwala a herbicides a m'dzinja pa nthaka yonyowa kungathandizenso kuti ntchitoyo ikhale yogwira mtima.
Ngati n'kosatheka kugwiritsira ntchito zochitika zomwe zisanachitike, kugwiritsa ntchito koyambirira pambuyo pa kutuluka kuyenera kugwiritsidwa ntchito momwe zingathere.
Kubzala koyambirira kuyenera kuwongolera udzu wovuta, monga udzu wapachaka kapena bromine wosabala.Komabe, ndikofunikira kupewa kuthira mbewuyo ikadutsa m'nthaka, komanso kuthira utsi wotsikirapo ngati n'kotheka.
Pendimethalin imatha kuletsa udzu wapachaka ndi udzu, ndipo zosakaniza zonse zimakhala ndi DFF kuti zithetse udzu.
Komabe, pamene alimi ali ndi vuto la bromine, ayenera kuyesetsa kupewa kulima balere chifukwa pali njira zambiri zoyendetsera tirigu wachisanu.
Alimi omwe ali ndi vuto la bromine ayenera kuwonjezera acetochlor mu osakaniza.Pa balere, mlingo wa fluorobenzene acetamide uyenera kukhala wokwera, ndipo ungafunike kugwiritsa ntchito zinthu ziwiri monga Firebird.
Amene ali ndi vuto la bromine mu tirigu wachisanu amakhala ndi zosankha zambiri.Akhozanso kusankha kutenga Broadway Star mu kasupe (afunika 8 madigiri kutentha), koma herbicide woyamba kulamulira bromine ayenera kukhala pamaso kapena mwamsanga pambuyo kuonekera.
Olima akuyeneranso kulabadira kukula kwa oats pamalo omwe Avadex Factor amagwiritsidwa ntchito, ndipo sangathe kulima oats mpaka miyezi 12 atagwiritsidwa ntchito.
Njira ina yoti udzu ndi udzu zikhale zovuta ndikuthira mankhwala achiwiri kumutu ngati pali umboni wa udzu pambuyo pa nyengo, chifukwa vutoli likhoza kufalikira kuchokera kumutu kupita kumunda.Zachidziwikire, izi zimangokhala ngati mitengo ndi ma tag amalola.
Komabe, kuyang'anira chikhalidwe ndi njira yoyamba yodzitetezera, ndipo njira zina zonse ziyenera kugwiritsidwa ntchito kuchepetsa kudalira mankhwala ophera udzu.
Kwa alimi ena nthawi yachedwa kusankha njira ina, koma kuchedwetsa kubowola kungathandizenso kuchepetsa vuto la udzu.Tchati chotsatirachi chochokera ku Teagasc chikufotokoza za kumera kwa udzu nthawi zosiyanasiyana pa chaka.
Mwachitsanzo, ngati muyang'ana bromine wosabala, idzawoneka pakati pa July ndi November, kotero kuchedwa kubzala balere m'nyengo yozizira mpaka October kudzachepetsa chiwerengero cha anthu, ndipo kuchedwa kwa tirigu mpaka November kungathandize kuchepetsa chiwerengero cha zomera.
Pali njira zambiri zothanirana ndi udzu kunja uko, kotero onetsetsani kuti mwathira udzu woyenera kwambiri pagulu la udzu.Nkhani zofananira Kuwona momwe namsongole amachitira mbewu zogwiriridwa zitamera.45% ya alimi olima adati kugwiritsa ntchito ukadaulo ndikoletsedwa ndi mtengo
Sabata iliyonse tidzakutumizirani chidule cha nkhani zofunika kwambiri zaulimi ndi ulimi kwaulere!
