Powdery mildew - zizindikiro, kupewa, mankhwala

Matenda a mbewu zambiri za m'munda. Amatchedwa bowa. Zikuwoneka ngati chovala choyera, choyera. Masamba omwe amakhudzidwa ndi bowa ili ndi kugwa. Chomera chikufota ndipo posachedwa amafa. Mildew ikuwonekera nthawi yonse yamunda, "ikukula" mkati mwa mwezi mutatha kuwonekera. Zomwe zimayambitsa ma bowa pamasamba ndi izi: zimakhuthala kubzala, nthaka yosauka, ulimi wothirira, kutentha kwakukulu kutentha kwa tsiku ndi usiku (kutentha).

Powdery mildew ndi weniweni. Chizindikiro chachikulu ndi mawonekedwe a chipika chopangidwa pamwambapa osati pamasamba okha, komanso pa zimayambira komanso maluwa. Matendawa amachepetsa msanga. Masamba achoke, koma musagwe kwa nthawi yaitali. Chifukwa chake chiri muzomera zowonjezera ndi kuthirira pang'ono. Chitsanzo ndi powdery mildew pa gooseberries: masamba opotoka amasiya kukula, owuma, kupuma; Zipatso, osati kukula, zimadulidwa. Zotsatira zake - kusowa kwa zokolola ndi imfa ya chomera chaka chimodzi kapena ziwiri.

Powdery mildew ndi wabodza. Chizindikiro chachikulu - kutuluka kwa mawanga "otayika" kapena a chikasu pamwamba pa pepala, m'munsimu amasonyeza nkhungu. Chomeracho chikufooka, kukhala choipa. Kuwoneka kwa zipatso ndi kotheka, koma khalidwe lawo ndilochepa, ndi maonekedwe osiyana. Chitsanzo ndi powdery mildew pa nkhaka. Chifukwa chachikulu cha kuoneka kwa bowa chotero pa chomera chiri mu usiku wochepa komanso kutentha kwa masana.

Chithandizo cha zomera zomwe zakhudzidwa ndi zotheka, koma ndi bwino kuganizira za kupewa. Kuthana ndi kukula kwa kubzala, sankhani malo othamanga ndi mphepo, kupereka madzi okwanira nthawi zonse, kupeza mitundu yambiri ya zomera zosagwirizana ndi bowa. Kuchotsa mphukira ndi kachilombo kumatenthedwa. Nthaka m'mayendedwe ndi kuzungulira tchire imakumbidwa, pambuyo pake feteleza ndi feteleza (nitashi ndi phosphate-nitrojeni) zimapangidwa.

Zotsatira zabwino ndi kupopera mbewu kwa zomera ndi ofooka njira ya koloko phulusa (0.5%) ndi Kuwonjezera kwa samba yowamba zovala. Fukani kangapo: musanayambe maluwa, mwamsanga mutatha, musanakolole (masiku khumi) komanso mu masabata awiri.

Ngati powdery mildew yadziwonetsera kale, yerekezani zomera zomwe zakhudzidwa (kuchotsa malo omwe kale ali ndi kachilomboka (masamba ndi ngakhale nthambi), fungicide.) Mankhwala amatanthauza kuti, kutsata ndi kuchuluka kwa zida zoteteza (magolovesi, maski) ndilololedwa.

Zimakhudza kwambiri kugwiritsa ntchito mankhwala "Topaz". Amafuna mankhwala awiri, ngakhale amodzi (pambuyo pa maluwa)

Mankhwala ena omwe amati amalowetsa Bordeaux osakaniza ndi "HOM". Tchire timayambidwa pamaso pa maluwa, malingana ndi malangizo.

Kwa anthu, "mankhwala a pakhomo" akufala: sopo la sopo lofewa ndi 20 g ya vitriol imathetsedwa mu chidebe cha madzi (malita 10). Njira yothetsera buluu yowonongeka imathandizidwa ndi zomera mwamsanga mutatha maluwa.

Angathe kupatsidwa mankhwala a sopo (50 g) ndi soda (50 g), atasungunuka mu chidebe cha madzi. Mitengo imatsanulidwa kuchokera kuthirira akhoza ndi bwino strainer pamaso masamba kusungunuka (pa chitsamba - atatu malita a yankho) ndi pambuyo maluwa.

Enanso, osati njira yovuta kwambiri, idzafuna 3 kg ya phulusa ndi chidebe cha madzi otentha (phulusa limatsanulidwa ndi madzi otentha). Kulowetsedwa kuchokera phulusa kumafunikira pa zomera pamaso pa maluwa, ndiyeno pambuyo pake (masiku pafupifupi khumi).

Inde, maphikidwe onse sayenera kugwiritsidwa ntchito kamodzi, kudzakhala kuwonekera kosavuta, komwe kungangowonjezera mkhalidwewo. Ndi bwino kusankha njira imodzi, yoyenera. Kawirikawiri, mankhwala awiri pachaka ndi okwanira. Makamaka ngati mutabzala (kapena kufesa) mumasankha mitundu yomwe imatsutsidwa ndi powdery mildew.

Ndi mfundo ina yofunika kwambiri: mbande zatsopano, zomwe zangotengedwa kale, ziyenera kukhala zotetezedwa mosalekeza. Njira yabwino ya cholinga ichi idzakhala 1% mkuwa wa sulphate. Mbewu zimasungidwa mu njirayi kwa mphindi zisanu, kutsukidwa ndi madzi ndikubzalidwa.
