I-Acer negundo 'Aureomarginatum'
El acer negundo, Eyaziwa ngamagama afana nemephu yaseMelika okanye imephu yebhodi, ngumthi onqabileyo onamagqabi akhumbuza ezo zeFraxinus (imithi yomlotha). Luhlobo olukhula ngokukhawuleza olukhula kwindawo ezinemozulu epholileyo, kodwa ingakhuliswa nakwiindawo ezifudumeleyo, ezinje ngeMeditera.
Nangona ithathwa njengesityalo esinganyangekiyo, inyani kukuba ineentshaba zayo. Sazise zithini izinambuzane nezifo ze acer negundo, nendlela yokubaphatha.
Izinambuzane
Cottony mealybug
Izitshabalalisi ezinokukuchaphazela, ngakumbi kwiinyanga ezifudumeleyo nezomileyo, zingaphezulu kwazo zontathu ezi zinto: mealybugs, i ntwala kunye imibungu. Unokuthintelwa ukugcina ukufuma okuphezulu Ngelixa kusembizeni, nokuba kungokutshiza amagqabi ngemini yasemva kwemvula, amanzi acociweyo okanye osmosis, kodwa nje ukuba ikhule kuya kuba luncedo ngakumbi ukuthatha ubhaka kubulala zinambuzane kwaye uyigcwalise ngedosi eboniswe kwisitya kunye neoyile yeParafini umzekelo, okanye ioyile yeNem.
Kwimeko apho umthi sele unezinambuzane ezithile, ukuba zimbalwa, zinokususwa nge-swab ezindlebeni ezifakwe emanzini ngesepha yesandla esincinci. Kodwa ukuba isityalo sichaphazeleke kakhulu, kuyakufuneka ukhethe iichiza zokubulala izinambuzane njengeChlorpyrifos.
Izifo
Umonakalo wePhytophthora
Izifo ezinokukuchaphazela kakhulu luhlobo lokungunda, okanye yintoni enye, ezibangelwa ngumngundo. Iifungi zizidalwa ezincinci ezithi, ngaphandle kokuziphatha kwezinye izinto eziphilayo, azizizo izilwanyana okanye izityalo, kodwa zezodidi olwahlukileyo.
yakhe Kunzima kakhulu ukuphelisaKuba iimbewu zincinci, zincinci kuneyona mbewu incinci yesityalo, kungoko zinokuqhutywa ngumoya njengothuli. Yiyo loo nto iintsholongwane zinokungena kuwo naliphi na inxeba elincinane lomthi, lihlume kwaye liwenze buthathaka.
Ukuyiphepha, Kubaluleke kakhulu ukuba ungagcini umhlaba okanye umhlaba ngalo lonke ixesha unkcenkceshela, kunye nokwenza uthintelo ngobhedu okanye isalfure. (Lumka kakhulu ukuba unezilwanyana zasekhaya okanye abantwana abancinci, kuba zinetyhefu xa zingenisiwe). Kodwa ukuba umthi sele uqalile ukuba namagqabi amdaka okanye amnyama, ukuba uyakhula nje, kungcono ukusebenzisa indlela yokubulala ukungunda.
Kwaye ukuba ufuna ulwazi ngakumbi, in eli elinye inqaku Sikuxelela ukuba zeziphi iimpawu zezona zitshabalalisi ziphambili nezifo.
Ngaba ubusazi malunga nezitshabalalisi kunye nezifo ze acer negundo?
Ndizibonile iimephu ezimnyama ezichaphazeleka ngumngundo we powdery
Molo Vincent.
Ewe, ukungunda okungumgubo kuchaphazela izityalo ezininzi, kubandakanya imephu emnyama.
