Ngati powdery mildew ikuwoneka pa petunia - momwe mungachitire ndi mliriwu?

Petunia si chomera chamkati chokha, komanso chomera chakunja chomwe chimagwiritsidwa ntchito kukongoletsa mabedi am'mayiko ambiri.

Ngakhale samadzisamalira, nthawi zina powdery mildew imamukhudza. Kodi ndizotheka kuthetsa matendawa?

Chifukwa chake, kuchokera m'nkhaniyi muphunzira za powdery mildew, momwe zimakhudzira maluwa ndi momwe mungalimbanirane nawo.

Mwachidule za chomeracho ndi mawonekedwe ake

Ma petunias othamanga komanso ampelous amakula mwachangu kuposa wamba. Mukathetsa vutoli ndi kuyatsa kowonjezera, kuwombera kwapakatikati kumapangika mwachangu, kenako kotsatira, kutambasula kuchokera pomwepo. Popanda kuwala, mphukira zam'mbali zimakulirakulirabe ndikukula m'mwamba. Mutha kusintha mawonekedwe amtchire posintha ndende.

Olima alimi odziwa zambiri amatsina tchire nthawi yakukula. Amachita izi kuti achepetse chitukuko cha petunia. Otsatira anabzala mitundu yosakanizidwa, atakhala ndi mawonekedwe abwino a chitsamba. Pakukula iwo, palibe njira zapadera zaulimi zomwe zimagwiritsidwa ntchito. Zidzafunika pakubzala mbewu za ampelous petunias: chitsamba chimapangidwa ndi kutsina, komabe sizingatheke kuyisandutsa "mpira" wowoneka bwino.

Zofunika. Kodi mungapewe bwanji ampelous petunias kuti asamange zazingwe zazitali? Ndikofunika kuteteza maluwa mpaka chitsamba chipangidwe. Izi zimatenga miyezi itatu kapena kupitilira apo.

Basic za matenda

Powdery mildew kapena mycelium wa parasitic powdery mildew ndi tiziromboti tomwe timalowa m'maselo a petunia ndikumwa timadziti tonse timeneti. Mukanyalanyaza pachimake choyera, posakhalitsa masamba am'munsi amasanduka achikasu, amapachika ndikugwa (chifukwa chiyani masamba a petunia amasanduka achikasu?).

Kumalo kumene myceliums amamangiriridwa, zilonda zimapezeka... Minofu yamoyo imazimiririka pamene tiziromboti “timadya”. Powdery mildew ndi ovuta kuzindikira: kusowa kwa michere sikukhudza ma petunias m'njira yabwino kwambiri. Chifukwa chakusokonekera kwa photosynthesis, ifa ngati njira zoyeserera sizikutsatiridwa.

Zoyambitsa

Powdery mildew ndi matenda a fungal omwe amayambitsidwa ndi tiziromboti tomwe timakhala kumtunda kwa nthaka. Sichikugwira petunia ngati wolima amasamalira. Amadziwa kuti ma powdery mildew spores adayambitsidwa motere:

• Mphepo yonyowa yozizira (kutentha kwa usana ndi usiku kuli pafupifupi + 20 madigiri Celsius, ndipo chinyezi chamlengalenga chimapitilira 70%).
• Owonjezera nayitrogeni m'nthaka.
• Kachulukidwe ka zokolola.
• Kuthirira kosayenera komanso kosasinthasintha.

Nthawi zina powdery mildew imakhudza petunia pazifukwa zina. Matendawa samachitika chifukwa chosagwirizana ndi mndende. Tizilombo timafikako kuchokera ku mbewu zoyandikana, kudzera m'madzi kapena chifukwa chosasamala zodzitetezera ndi wamaluwa mwiniyo (kudulira chomera chopanda thanzi komanso chokhala ndi chida chomwecho popanda chithandizo chothira mowa).

Kuzindikira

Kwa nthawi yoyamba iwo anayamba kulankhula za powdery mildew ku Russian Federation kumayambiriro kwa zaka za zana la 20... Wothandizira wake ndi bowa Sphaerotheca pannosa. Ndikosavuta kuzindikira chomera chomwe chili ndi kachilombo:

1. Choyamba, zokutira zoyera zimawonekera. Amawoneka pamasamba ndi inflorescence.
2. Patatha masiku angapo, madontho ngati mame amawoneka pa zimayambira ndi pamakhala.

Olima alimi odziwa zambiri amati matendawa amafalikira kuchokera kumunsi kwa masamba mpaka kumtunda, kuphatikizapo masamba. Popanda kuchitapo kanthu, chomeracho chidzaola ndi kufa.

Chisamaliro. Njira yabwino yodziwira ngati powdery mildew ikukula pa petunia ndikuyang'ana kwambiri masana.

Kodi mungathetse bwanji vutoli?

Pochiza petunia, mndende zikusinthidwa:

1. Amathirira madzi pafupipafupi ndipo pokhapokha atazindikira kuti dothi lapamwamba lauma.
2. Wokulitsa maluwa amasiya kupopera mankhwala, ndikuyika mphika wamaluwa pazenera, lomwe "limayikidwa" m'mawala a dzuwa.
3. Amatola masamba omwe ali pafupi ndi m'mphepete mwa nthaka. Izi zimathandiza kuti matendawa asafalikire kumtunda kwa chomeracho.

Osati onse omwe amalima amagwiritsa ntchito mankhwala osokoneza bongo polimbana ndi powdery mildew, ngakhale akudziwa za mphamvu zawo. Amakhulupirira kugwiritsa ntchito njira zowerengera. Petunia adzachira ngati atalandira yankho lokonzedwa kuchokera:

• 250 ml ya mkaka;
• 750 ml ya madzi;
• 1 tsp mchere.

Mutatha kusakaniza zinthu zomwe tatchulazi, tsanulirani mu botolo ndikupopera petunia ndi botolo la kutsitsi.

Algorithm mankhwala ndi fungicidal mankhwala

1. Kusintha momwe zinthu zimasamaliridwira. Amachotsedwa pazenera lomwe limamira m'mazira a dzuwa ndipo samakonda kuthiriridwa ndi petunia.
2. Madera omwe ali ndi kachilombo amachotsedwa, i.e. masamba, achikasu ndi masamba osalala.
3. Dothi lapamwamba limachotsedwa, ndipo m'malo mwake, lina limatsanuliridwa - kukonzedwa.
4. Utsi ndi fungicides, kuwasakaniza malinga ndi malangizo a wopanga.
5. Onetsetsani kuti yankho lifika pamagawo onse a petunia.
6. Zikakhala zovuta kwambiri, chomeracho chimamizidwa mu chidebe ndi yankho.

Zothandiza wowerengeka azitsamba

1. Njira yothetsera sopo ndi kuwonjezera phulusa la soda... Pokonzekera, tengani magalamu 20-25 a soda, malita 5 a madzi otentha ndi magalamu 5 amadzi (sopo wochapira). Chosakanizacho chazirala, kenako nkuchipopera muzu wa nthaka. Pafupipafupi wa ndondomeko ndi kawiri pa masiku 7-10. Osazichita, powona kuti zizindikiro za powdery mildew zatha.
2. Njira yofooka ya potaziyamu permanganate... Amakonzedwa pothetsa magalamu awiri a potaziyamu permanganate mu 10-13 malita a madzi. Pafupipafupi pokonza kamodzi pamasiku asanu. Chiwerengero cha ndondomekoyi ndi 3.
3. Kusakaniza kwa sopo ndi phulusa... Amakonzedwa kuchokera ku 1 kg ya phulusa la nkhuni ndi malita 10 amadzi otentha. Pambuyo poyambitsa ndikulimbikira masiku 5-7, onjezerani magalamu ena a sopo kwa 5-10 ndikukonzekera chitsamba. Zisanachitike, zosefa. Phulusa silitayidwa ndi kuthiridwa mumphika wodyetsera.

Bungwe. Mankhwala azitsamba omwe tafotokozazi sangathandize ngati mlimiyo atazindikira powdery mildew pa petunias mochedwa.

Ndi iti mwa "chemistry" yomwe ndiyabwino kukonza?

Mafungicides amathandiza kulimbana ndi powdery mildew. Amawononga kapangidwe ka bowa, ndikuletsa kukula kwake m'maselo amaluwa.

Fundazol

Fungicide iyi ndiyotakata kwambiri. Zimathandiza ngati matenda a masamba, masamba ndi mbewu amapezeka pazomera zamkati. Kuchita bwino kwa Fundazole kumachitika chifukwa cha kupezeka kwa benomyl.

Izi zimalowa mmera kudzera m'masamba ndi mizu. Pambuyo pake, amasandulika carbendazim, yomwe imawonetsa mawonekedwe abwino kwambiri a fungicide. Pambuyo pokonza, Fundazol imakhalabe pamtunda. Amangolowa m'mbewu pang'ono. Chifukwa cha ichi, petunia amatetezedwa bwino ku kachilombo koyambitsa matenda a powdery mildew.

Fundazole imagulitsidwa m'thumba la 10 gramu. Mtengo - 17 rubles. Njira yotsukira - 1 gramu / 1 tsp. madzi. Pambuyo poyimitsidwa koyambirira, kuchuluka kwa njira yothetsera ntchito kumabweretsedwa ku 1 litre... Ndikofunika kuphatikiza kuthirira ndi kupopera mbewu mankhwala kuti muchotse bowa. Pakati pa nyengo, chomeracho chimachiritsidwa kawiri, ngati koyamba sizinali zotheka kuwononga.

Zowonjezera

Mafungowa ophatikizana ndi othandiza polimbana ndi matenda ambiri, kuphatikizapo powdery mildew. Ndi chithandizo chake:

• yonjezerani nyengo yokula;
• kuonjezera kugwiritsa ntchito bwino madzi;
• sintha kusintha kwa zithunzi, kusintha kwa nayitrogeni;
• ziletsa mapangidwe a ethylene.

Amistar extra ndi mankhwala omwe amapangidwa ngati yankho lamadzimadzi. Ku Russia, amagulitsa m'mazitini a lita imodzi pamtengo wa ma ruble 1,500 / lita imodzi. Njira yothetsera vutoli imakonzedwa ndikusakaniza fungicide ndi madzi pamlingo wa 1: 10 kapena 1: 4. Pambuyo pa kugwedeza, chomeracho chimathandizidwa nacho.

Kuthamanga

Mutha kuchiza petunia mukagula kukhudzana ndi systemic fungicide Skor pamtengo wa ma ruble 8300 pa 1 litre. Chofunika kwambiri mmenemo ndi difenoconazole.

Kwa chithandizo, kuchepetsa 2 ml ya mankhwala mu malita 10 a madzi. Sigwiritsidwe ntchito pokonza nthawi yomweyo itatha. Patatha masiku makumi awiri, petunia amachiritsidwa katatu.

Chithunzi

Mu chithunzi chomwe mwapereka pansipa, mutha kuwona momwe petunia yomwe yakhudzidwa ndi powdery mildew imawonekera komanso momwe mungathanirane ndi matendawa kunyumba:

Njira zodzitetezera

Powdery mildew ndi matenda wamba. Mukatsatira malangizo omwe ali pansipa, petunia sadzadwala..

• Kukulitsa petunias mumphika pazenera lowala bwino.
• Miphika yomwe ili pazenera imayikidwa patali kwambiri kuchokera ku imzake kuti iteteze kufalikira kwa tizilombo ta fungal.
• Ngati palibe malo okhala pa petunia, amawononga kuti asapatsire ena.
• Chomeracho chimathiriridwa m'mawa kuti chiwonjeze kulimbana ndi matenda.
• Ngati mumadyetsa, ndiye phosphorous ndi potashi yokha, osati feteleza wa nayitrogeni.
• M`pofunika kuti utsi iye ndi decoctions wa horsetail kapena tansy nthawi.

Mapeto

Ngati mupanga nyengo yoyenera kukula ndi maluwa, powdery mildew sichidzawopseza petunias. Ataona chovala choyera, amachitapo kanthu mwachangu. Atataya nthawi, chomeracho chimatha kufa, ndikupatsira ena atayima pafupi pazenera.
