Funso: Kodi ndi bwino kuchiza udzu kuti uteteze nkhanu tsopano, kapena tizidikirira kuti ikule tisanauphe ndi mankhwala ophera udzu?M'chilimwe chatha, ndinayika mankhwala ophera udzu.Ndi zokwanira?Kodi mukuganiza kuti verbena adapulumuka m'nyengo yozizira?Mbali ina ya udzu wanga ndi yofesedwa kumene.
Yankho: Chomera cha hawthorn chomwe mudabzala paudzu wanu chaka chatha chafa.Komabe, asanamwalire, ambiri amatha kutulutsa njere zambirimbiri, zomwe tsopano zidzamera paudzu wanu m’masabata angapo otsatira.Njira yopewera kuphulika kwa mpunga ndi kuthetsa vutoli, osati kuyesa kupha namsongole atakhazikika pa udzu wanu.
Ngakhale kuti nthawi yophukira ndi nthawi yabwino yochizira namsongole ndi mankhwala a herbicides, palibe phindu lochulukirapo pogwiritsira ntchito zoletsa za verbena mu kugwa, chifukwa verbena imakhala pachaka m'chilimwe ndipo imamera kumayambiriro kwa kasupe m'malo mwa kugwa.Kuzizira kwambiri m'nyengo yozizira kukafika, zomera zimafa.Mbeu za verbena zisanayambe kumera ndikukula, verbena preventive (“pre-emergent herbicide”) iyenera kugwiritsidwa ntchito.
M'kapinga kumene mwabzalidwa kumene, muyenera kusankha ndi kugwiritsa ntchito mankhwala ophera udzu mosamala kwambiri kuti mupewe kupha kapena kuwononga udzu watsopano womwe mwabzala.Pakati pa mwezi wa March mpaka pakati pa mwezi wa April ndi nthawi yabwino kwambiri yogwiritsira ntchito mankhwala ophera udzu asanatuluke kuti athetse udzu wa horsetail.Mankhwalawa amawapaka udzu usanamere.Amatha kuteteza mbeu za horsetail kuti zisamere kapena kupha mbande za horsetail zikayamba kumera.Onetsetsani kuti mankhwala omwe mumagula atha kugwiritsidwa ntchito bwino pa udzu watsopano womwe uli ndi zinthu zogwira ntchito monga siduron (Tupersan).Izi zitha kugwiritsidwa ntchito pobzala kapena mutabzala masika.Ikhoza kulamulira udzu wa horsetail ndi udzu wa nkhandwe.
Pa udzu wokhwima, mutha kusankha njira zambiri zowongolera udzu wa kavalo usanamere, udzu wa foxtail ndi nthenga za tsekwe, kuphatikiza befen+trifluralin (Team), benzsulfone (Betasan, PreSan, Lescosan), ndi Austrian Sand pine (Ronstar), pendimethalin ( Kuwongolera udzu, Pre-M, Halts, Pendulum), dithiopyr (Dimension), Prodiamine (Barricade) ndi bensulide + oxadiazon (foie gras/crab grass control).Kumpoto kwa Kentucky, mankhwalawa ayenera kugwiritsidwa ntchito pamaso pa April 15. Tsatirani pambuyo pa masabata asanu ndi limodzi ndikugwiritsanso ntchito mobwerezabwereza kuti muwonjeze maulendo olamulira m'nyengo yonse yachilimwe.Ngati gooseweed ndiye udzu womwe mukufuna, chonde chitaninso kachiwiri pa Meyi 15.
Udzu ukafesedwa, pa kapinga watsopano kapena pansi womwe udzafesedwe m'masabata angapo otsatira, kuletsa udzu wambiri si njira yeniyeni, chifukwa mankhwala ophera udzu ambiri amapha ma dandelion, clover, ndi plantain Grass, violets, ivy, ndi zina zotero. Zokhala ndi 2,4-D kapena zinthu zina zofananira, zimatha kupha kapena kuwononga udzu womwe wangophuka kumene.Yang'anani chizindikiro cha mankhwala kuti mudziwe zambiri, koma mankhwala ambiri a herbicides amatha kuikidwa pa udzu watsopano atadulidwa pafupifupi kanayi.Ngati mankhwala ophera udzu agwiritsidwa ntchito pa namsongole musanapale, muyenera kudikira milungu ingapo mutathira mankhwalawo musanafese mbewu za udzu.Yang'anani zomwe zili patsamba lazoletsa.
Pa udzu wokhwima popanda kubzala kwambiri, mutha kugwiritsa ntchito mankhwala ophatikizika okhala ndi 2,4-D kupha udzu wamasamba monga plantain, adyo wakuthengo, ndi dandelion.
Kuti mumve zambiri za kasamalidwe ka udzu ndi malo, komanso zosintha zamaphunziro ataliatali omwe akubwera, komanso kuti mupambane mbewu zamasamba zaulere m'munda wanu wamasika, chonde pitani ku www.facebook.com/BooneHortNews kapena www.twitter.com/BooneHortNews.
