Powdery isikhutha - izimpawu, nokuvinjelwa, ukuphathwa

Lesi sifo izitshalo eziningi zemifino. Ibangelwa ukhunta. Kubonakaliswa ngesimo powdery, umgwengwezi emhlophe. Amaqabunga abangenwa yilo ukhunta, ukoma up bese ewa. Lesi sitshalo buyabuna futhi uyafa maduzane. Impuphu livela kuyo yonke inkathi engadini, "echuma" inyanga emva ukuhluma. Izizathu ukuvela ukhunta phezu Amaqabunga ipulazi obukhulu kakhulu, enhlabathini abampofu, ukuchelela mafutha, ushintsho elibukhali lokushisa nsuku zonke maqondana ebusuku (ashisayo-abandayo).

Powdery isikhutha samanje. Uphawu oyinhloko - ukuvela kokuseshwa ezichazwe ngenhla, hhayi kuphela amaqabunga, kodwa futhi kwi neziqu, ngisho izimbali. Lesi sifo buthakathaka simila ngokushesha. Amahlamvu ukoma up, kodwa ningaweli isikhathi eside. Isizathu salokhu zokutshala eduze futhi ayakhala ayindlala. Isibonelo - isikhutha ku gooseberries: amahlamvu ezisontekile abhashe, ezomile, baphuke, amajikijolo, hhayi vyzrev, sidilike. Ngenxa yalokho - ukuntuleka kwesivuno futhi ukufa izitshalo ngonyaka noma emibili.

Impuphu kungamanga. The main uphawu - ukubonakala "egqwalile" noma ophuzi onsundu kuzindawo kusukela ishidi phezulu, phansi kubonakala isikhunta lemicu empunga elinamathela othini. Lesi sitshalo zibuthaka, kuba amabi. Ukubukeka izithelo kungenzeka, kodwa izinga yabo siphansi, nge nesigqi ezahlukene. Isibonelo salokhu powdery isikhutha on ukhukhamba. Imbangela enkulu yaleli ukhunta phezu isitshalo itholakala ongaphakeme kanye eliphezulu usuku okushisa ebusuku.

Ukwelashwa izitshalo abathintekayo kungenzeka, kodwa kungcono ukugxila zokuvimbela. Gwema ukutshala eduze, khetha indawo ezinomoya, ahlinzeke ukuthambisa njalo, ukuthengwa zezitshalo amelana ukhunta. Ezisusiwe amahlumela abangenwe amahlamvu zishiswa. Umhlabathi phakathi imigqa kanye ngimbe emaceleni sezihlahla whereupon eyenziwa ngokulinganisela sigqoka fertilizer (potassium ne phosphorus-nitrogen).

yi Good unika sprayings isixazululo ezibuthakathaka soda ash (0.5%) kulekelelwa ngensipho abavamile. Wafutha izikhathi eziningana: ngaphambi izimbali, ngokushesha ngemuva, ngaphambi kokuvuna (izinsuku eziyishumi) kanye futhi ngemva kwamasonto amabili.

Uma powdery isikhutha isivele ekuboniseni ngokwayo, aphathe izitshalo abathintekayo (qala ususe amasayithi okunobuthi (amahlamvu ngisho Amahlumela), a fungicide. Kusho zamakhemikhali, ngakho lo mkhosi enkulu futhi ukusetshenziswa imishini zokuzivikela (amagilavu, buso) ziyadingeka. Kanjani ungafunda on the isembozo.

Kahle kuthinta ukusetshenziswa kwezidakamizwa "itopazi". Kudinga ukucutshungulwa double, nakuba kwanele eyodwa kuphela (emva zom)

Enye izidakamizwa ethi esikhundleni Bordeaux ingxube - "IKHAYA". Ezihlabayo wafutha ngaphambi izimbali, ngokulandela imiyalelo.

Ngo bendlala "ikhaya ukwelashwa": sashintsha ibha insipho 20 g we sulfate yakhulela ibhakede lamanzi (10 L). Ehlungiwe isixazululo matte blue iphathwa izitshalo ngokushesha emva zom.

It ingelashwa nge isixazululo of yasendlini insipho (50 g) soda (50 g) ziyoncibilika ibhakede lamanzi. Ezihlabayo ziniselwa kusuka ukuthambisa can nge strainer esihle phambi ukuqhakaza amahlamvu (ku ehlathini - amalitha amathathu isixazululo) nangemva zom.

Esinye, indlela hhayi kakhulu isikhathi esiningi kuzodinga 3 kg umlotha futhi ibhakede lamanzi abilayo (amanzi abilayo wathela umlotha). Ukumnika umlotha wafutha izitshalo ngaphambi zom bese ngemva (samahora acishe abe kwezinsuku eziyishumi).

Yiqiniso, uma zonke izindlela akufanele isetshenziswe - kuzoba Overkill, ungakwazi kuphela babhebhethekisa lesi simo. Kungcono ukukhetha indlela efanele ngaphezulu. Ngokuvamile, ayinalo ukwelashwa ezimbili ngonyaka. Ikakhulukazi, uma ukufika (noma zokutshala) ukhetha izinhlobo ukuthi amelana powdery isikhutha.

Futhi elinye iphuzu elibalulekile: entsha, izitshalo asanda kuluthola, kumele decontaminated. I-ejenti enhle le njongo ukukhonza njengoba isixazululo 1% yethusi sulfate. Izithombo agcinwa kule isixazululo imizuzu 5, sihlanzwe ngamanzi bese batshala.
