Makhalidwe Otsika Osauka

Pakhala pali kuwonjezeka kwa downy mildew ku Impatiens zomera posachedwapa. Pang'ono ndi pang'ono mtundu wa mildew umakhudza kwambiri Plasmopara . Iyo imafalikira mofulumira, pansi pa zikhalidwe zoyenera, ndipo kamodzi kachilombo, palibe mankhwala. Komabe, pali njira zina zomwe mungapewere. Koma choyamba, apa pali maziko ena kuti akuthandizeni kumvetsa matendawa.

Downy Mildew ndi chiyani?

Matenda a Downy amayamba chifukwa cha oomycetes kapena zozizira za madzi. Zimakhala ngati bowa, koma zimagwirizana kwambiri ndi algae.

Pali mitundu iwiri ya spoy mildew spores. Mtundu umodzi, zoospores, ukhoza kupunduka ndi madzi kapena kufalikira ndi mphepo. Mtundu winawo, oospores, umakhala mkati mwa minofu ya zomera ndipo ukhoza kufalikira mofulumira ndi m'nyengo yozizira. Panthawiyi, palibe umboni wosonyeza kuti mtundu uwu wa mildew umene umakhudzidwa kwambiri ndi kuchita izi, koma bwanji kutenga mwayi.

Downy mildew imafala m'chaka ndipo imagwa pamene nyengo yozizira, yamvula kapena yamvula imapereka malo abwino.

Kodi Chimachititsa Kuti Mitundu Yabwino Ikhale Yotani?

Malinga ndi e-Grow Alert ya Nora Catlin, Wothirira Zamaluwa, Cornell Cooperative Extension ya Suffolk County, mitundu yotsatilayi ya matendawa imayamba kuchepa.

• Zonsezi zimachititsa kuti IANA , kuphatikizapo mitundu iŵiri ndi ya mini. Izi ndizomwe zimakhala zovuta kwambiri zomwe zimagulitsidwa m'madera olima. ( I. waller IANA hybrids, monga Fusion® mndandanda , sakhala ocheperapo, komabe amawopsa)
• Balsamu Yoperewera / Maluwa a Basamu ( I. Balsamu mu ) Izi ndizitali zazikulu kusiyana ndi zomwe zimachitika Ambiri, ndi masamba omwe amadziwika bwino.
• Ndalama zamtengo wapatali ( I. capers ndi ) Njuchi Zamtchire ( I. pallidum ). Kawirikawiri amaganiziridwa namsongole, koma ngati ali m'dera lanu, akhoza kufalitsa matendawa kumalo anu osakopa.

Amakhumudwa Osakhudzidwa

• Chipewa cha bhalaamu / apolisi ( Impatiens glanduliferous ), mitundu yowopsa komanso yowopsya yomwe imatha kufika mamita 6 mpaka 10 (2 - 3 mamita), imadwala matenda koma imatha kukhala ngati alendo.
• Dziko la New Guinea limapatsa chidwi ( Impatiens hawkers ) ndipo zinyama zake, monga SunPatiens®, zikuwonetseratu kukana.

Zikhoza kukhala ndi zomera zambiri zomwe zakhudzidwa kapena zomwe zimakhala zowonjezera, koma izi ndizomwe zilipo mpaka pano.

Zizindikiro za Makhalidwe Osauka pa Zosayembekezereka

Zizindikiro zoyambirira zimakhala zovuta kuziwona ndipo zingakhale zolakwika chifukwa cha vuto la zakudya.

1. Masamba atakanizidwa kapena chlorotic (chikasu) ndikuwoneka ngati akusowa feteleza.
2. Ntchentche kapena masamba otsika pansi.
3. Nthaŵi zina mabala oyera amatha kukhala pamunsi mwa masamba. Izi ndi spores ndipo kawirikawiri zimawoneka nyengo yozizira, yamvula. (Onani chithunzi patsamba 2.)
4. Pamene nthendayi imakula, zomera zimatha kukula ndikuyang'ana, kudumpha masamba kapena kugwa kwathunthu.

Zimene mungachite pa matenda a downy mildew.

Zomwe Tingachite Ponena za Downy Mildew pa Zovuta

Ngakhale kuti palibe mankhwala othetsera Matenda omwe ali kale ndi matenda a downy mildew, pali njira zomwe mungatenge kuti zisamalike.

Kupewa

Kupewa kugwidwa ndi matenda kwathunthu kungakhale kovuta kwambiri, chifukwa chodalira kwambiri nyengo. Mvula yambiri ndi yozizira, nyengo yamvula sitingapewe nthawi zonse. Koma pali zinthu zochepa zomwe mungapereke, kuti musapangitse zinthu kuipiraipira.

• Perekani mpweya wabwino. Musagonjetsere zomera zanu.
• Madzi ochokera pansi, kuyesa kuti asakamwe madzi masamba akamamwe madzi ndi madzi kumayambiriro kwa tsiku.
• Chotsani zitsamba zilizonse zokayikitsa nthawi yomweyo.

Chikhalidwe cha chitukuko ndi bet yako yabwino. Kamodzi kamodzi kamakhala ndi kachilombo, palibe mankhwala. Ngati mukufuna kuyesa kufalitsa kufalikira kwa matendawa ndi kuteteza fungicide, neem ndi zamkuwa zitsulo zikulimbikitsidwa kwa eni nyumba.

Kodi Zidzakhala Zotentha Kwambiri Ndiponso Zidzakhalanso ndi Zomera?

Pakadali pano, palibe chizindikiro chakuti chimapatsira mbewu, ngakhale kuti ena ali ndi mpweya wochepa - choncho pali mwayi. Matenda ena amatha kutentha kwambiri. Ngakhale kuti zikuoneka kuti sizikuchitika ndi mildy mildew, musatenge mwayi ndi composting zomera zokhudzidwa.

Ngati downy mildew imakhala vuto lalikulu m'munda wanu, muyenera kuganizira kuti musabzalidwe kwa chaka chimodzi kapena ziwiri. Mthunzi wachitsulo njira zina zosayembekezereka ndi New Guinea impatiens, begonias, ndi coleus.

Zoonjezera zothandiza:
Zovuta Zowonongeka - Zowonjezera (Koma Si Zonse) Kuyankha Mafunso
