Zina mwa mitundu yokongola ya m'dzinja m'munda wathu ndi asters . Pofuna kukulitsa nthawi zina zimafuna mphamvu ndi kuleza mtima, chifukwa aster amadwala matenda ndipo amaopsezedwa ndi tizilombo tosiyanasiyana, zomwe zikutanthauza kuti kumenyana nawo kumakhala koyenera nthawi zonse.
Matenda a asters osatha ndi apachaka
Zimatsimikizirika kuti aster imakhala ndi matenda oposa 20, kuphatikizapo kukumbidwa ndi tizirombo, koma mankhwala osankhidwa bwino ndi kutha kwa tizilombo tikhoza kuwononga zotsatira zake zoipa. Matenda ena amayamba kukhudza mbande zomwe zili kale mabokosiwo, zina zimachitika pokhapokha pa nyengo zina, ndipo zina zimabisala mpaka nthawi ya maluwa. Tiyeni tiyang'ane pa zomwe zimachitika m'dera lathu la nyengo.
Msolo wakuda
Ichi ndi chithokomiro cha fungal, chomwe zomera zambiri ndi astra zikukumana nacho. Zimakhudza mbande zonse musanadzalemo pansi, ndi zomera zakulira. Chizindikiro cha matendawa ndi tsinde lakuda ndikumera kwa tsinde muzu wa mizu, yomwe imatha kufika kutalika kwa 10-15 masentimita. Mbande, monga lamulo, zimatha msanga kwambiri, kuti zomera zimakula pang'onopang'ono kuzizira ndi kuwonongeka kwathunthu.
Pofuna kuteteza mbewuzo, mbewuzo zimachiritsidwa ndi yankho lamphamvu la manganese musanafese, mosamala mosamala. Ngati zomera zowonongeka kale zikudwala, zimachotsedwa kwathunthu, zimatenthedwa, ndipo nthaka imatsanulidwa ndi njira yothetsera kufalikira kwa bowa.
Mosaic (jaundice)
Matendawa amachititsa kuti anthu asadye, koma mbewu zina zamaluwa. Amakhala ndi chikasu cha masamba, omwe amakhala osayanjanitsika - ndi malo owala komanso amdima, kumene dzinacho linachokera. Matendawa amayamba ndi pakatikati, pang'onopang'ono kulanda mbewuyo. Mafinya amavutika komanso amakhala ndi maonekedwe a chikasu m'malo mwa mthunzi wowala. Mitengo yodwala imachotsedwa muzu ndi kutayidwa, kapena kutenthedwa, ngati mankhwala osokoneza bongo alibe mphamvu yotsutsa matendawa.
Powdery mildew
Chidebe, chofanana ndi ufa wonyansa pa zimayambira ndi masamba a aster amayamba ndi bowa. Icho chingachotsedwe ndi njira yothetsera sulfure kapena soda komanso sopo. Ngati matendawa afalikira, ndi bwino kuononga chomera ndi moto, mwinamwake wintering mycelium imabwereranso ndi asters m'malo abwino.
Fusarium
Kuchokera pokonzekera, kusiyana ndi kuthekera kuti azitha kudwalitsa matenda monga fusarium, chidwi cha Readzol, cobalt chloride, Topsin-M, magnesium sulphate. Imeneyi ndiyo matenda omwe amafala kwambiri mumasamba oyamba omwe amayamba ndi masamba a chikasu, ndipo amawuma, ndipo mikwingwirima yakuda imapezeka pamayambira. Ngati nthawi sichichita kanthu, mbewuyo imamwalira.
Kodi mungapange bwanji asters ku tizirombo?
Kuwonjezera pa matenda, asters ndi tizilombo ting'onoting'ono timayesedwa. Izi ndi izi:
- fosholo;
- kangaude;
- bugwiri;
- penbbering penny;
- chithunzi;
- chisanu cha astrova;
- slug.
Zirombo zonsezi zimavulaza zomera zobiriwira - zimamwa juzi zopatsa moyo,
Kupopera mankhwala ndi chlorophos kudzawononga chiwonongeko, ndipo "Somazol" idzawononga earwig. Kuonjezerapo, pamaso pa tizilombo pamtengowo, m'pofunika kusunga kayendedwe ka mbeu - musabzale zomera ziwiri zaka zotsatira motsatira malo omwewo. Zimayenera kulima nthaka ndikuchotsa namsongole. Kuwona miyezo yaukhondo m'zinthu zambiri kudzasunga munda wamaluwa kuchokera ku mavuto omwe ali ngati matenda ndi tizilombo toononga.
