Mukapeza chovala choyera choyera pa masamba kapena masamba a bulauni, zomera zimakhudzidwa ndi powdery mildew. Kuvala kowala kumayamba kuchepa ndipo mapeto ake amapeza chophimba. Izi ndizomwe zimangokhala ngati mycelium yomwe imakhala ndi zomera. Brown mipira ndi bowa spores. Kuopsa kwa matendawa ndi motere: chomeracho chimataya kwathunthu kukongola kwake, ndipo malo okhudzidwawo amayamba kutembenuka wakuda ndikufa. Ngati inflorescences akhudzidwa, sangathe kupanga mazira. Komanso, matendawa amachepetsa kukana pa nthawi yozizira.
Monga lamulo, kuyamba kwa matenda kumachitika kumayambiriro kwa chilimwe. Panthawi imeneyi, spores amasulidwa ku chipatso thupi la bowa. Mu nthawi youma nthawi ya kutentha, pamene pali lakuthwa kusinthasintha mu kutentha ndi chinyezi, malo abwino kuti chitukuko cha powdery mildew kuonekera. Zimapezeka kuti maonekedwe a matendawa amachititsa kwambiri ntchito ya nayitrogeni feteleza. Ngati kudulira kolimba kumatheka, chomeracho sichitha.
Powdery mildew ndi matenda a fungal. Amapititsidwa ndi mphepo kapena kupuma kwa madzi pa ulimi wothirira.
Kodi kuchotsa powdery mildew?

Nkhondo yolimbana ndi powdery mildew iyenera kuyambika pa nthawi, mwinamwake imayambitsa mliri wonse. Bowa limakonda nyengo yozizira pamtunda, kotero ndikofunika kuchotsa nthawiyo ndikuwotchera kapena kukulitsa m'nthaka.
Pa tchire la gooseberries ndi currants ayenera kudula bwanji zatha malekezero m'chaka. Onetsetsani kudyetsa tchire ndi feteleza "zolondola". Asanayambe komanso pambuyo maluwa, m'pofunika kuchiza chomera ndi calcined koloko. Kamodzi mu 2-3 zaka ndi ololedwa kugwiritsa ntchito kuthetsa kupopera mbewu mankhwalawa ndi zitsulo sulphate yankho.
Mu strawberries, tchire ndi tizilombo toyambitsa matenda, matenda amakhudza mbali yokhayokha. Pachifukwa ichi, masamba amayamba kuwomba ndi kugwa. Mukhoza kupopera zomera ndi sulfure yamakono kamodzi pa sabata. Nazi maphikidwe ochepa:
- Sakanizani 50 g wa sulfure ndi 5 g zamkuwa sulphate ndi kuchepetsa mu 10 malita a madzi;
- Sakanizani 100 g ya sopo yowatsuka ndipo muonjezerepo 5 g ya vitriol, yonse iwonetsedwe mu malita 10 a madzi;
- mungathe kukonzekera yankho la mullein mu chiŵerengero cha 1:10, ndikuumiriza maola 4.
Palinso njira zambiri zomwe munthu angathe kuchotsera mame a powdery. Nazi maphikidwe ochepa:
- mu madzi okwanira 1 litre, sungunulani 4 g wa soda phulusa ndi 4 magalamu a sopo yophika zovala. Njira yothetsera vutoli imayambitsidwa ndi zomera kawiri mlungu uliwonse;
- 1 lita imodzi ya madzi otentha sungani theka la galasi la phulusa. Kuumirira masiku awiri. Sungunulani yankho lanu ndi kuwonjezera pamenepo 4 g wa sopo losungunuka. Pangani zomera kawiri pamphindi pa sabata.
Powdery mildew pa maluwa
Kwa wolima maluwa, vuto ili ndi lofunika kwambiri, chifukwa matendawa amakhudza maluwa amkati.
Koma chimodzimodzi, njira zothetsera powdery mildew pa maluwa alipo. Pofuna kusunga chomera, muyenera kuchitapo kanthu mwamsanga. Pali njira yapadera ya powdery mildew, yomwe ingagulidwe m'masitolo a florists. Mankhwala "Topaz" amagwiritsidwa ntchito molingana ndi malangizo a zomera zonse, ngakhale zathanzi. Nthawi zambiri zimatha kukonza maluwa kamodzi.
