Powdery pwm - cov tsos mob, kev tiv thaiv, kev kho mob

Tus kab mob ntawm ntau zaub cov qoob loo. Tshwm sim los ntawm ib cov pwm. Nws manifested nyob rau hauv daim ntawv ntawm ib tug powdery, dawb txheej. Nplooj cuam tshuam los ntawm no pwm, curl li thiab poob tawm. Cov nroj tsuag withers thiab tuag sai sai no. Powdery pwm zoo nkaus li thoob plaws hauv lub vaj lub caij, "flourishing" nyob rau hauv ib lub hlis tom qab germination. Yog vim li cas rau cov emergence ntawm lub pwm rau cov nplooj heev tuab plantation, cov neeg pluag av, ywg dej ntshiv, ntse hloov nyob rau hauv txhua txhua hnub kub nyob rau hauv relation mus rau hmo ntuj (kub-txias).

Powdery pwm tam sim no. Lub ntsiab mob - lub rov tshwm sim ntawm ib tug tua tau piav saum toj no, tsis tsuas yog nyob rau hauv cov nplooj, tab sis kuj nyob rau hauv lub stems, thiab txawm paj. Tus kab mob tsis muaj zog txog cov nroj tsuag sai sai. Cov nplooj curl li, tiam sis tsis txhob poob rau ib ntev lub sij hawm. Yog vim li cas rau qhov no ze cog thiab ywg dej scarce. Piv txwv li - pwm rau gooseberries: twisted nplooj nres loj hlob, qhuav, tawg; berries, tsis vyzrev, crumble. Raws li ib tug tshwm sim - tus tsis muaj sau thiab txoj kev tuag ntawm cov nroj tsuag nyob rau hauv ib lub xyoo los yog ob tug.

Powdery pwm yog cuav. Lub ntsiab mob - tsos ntawm "faded" los yog daj-xim av me ntsis los ntawm cov saum toj kawg nkaus daim ntawv, hauv qab zoo nkaus li grayish pwm. Cov nroj tsuag tsis muaj zog txaus, nws yuav dab tuag. Cov tsos ntawm cov txiv hmab txiv ntoo ua tau, tab sis lawv zoo yog tsawg, nrog txawv hom. Ib qho piv txwv yog lub powdery pwm rau dib. Lub ntsiab ua ntawm no pwm ntawm cov nroj tsuag cov lus dag nyob rau hauv cov tsawg thiab siab hnub hmo ntuj kub.

Kev kho mob ntawm cov nroj tsuag yog ua tau, tab sis nws yog zoo dua rau siab rau kev tiv thaiv. Tsis txhob nyob ze cog, xaiv ib tug cua hlob qhov chaw, muab tsis tu ncua watering, purchase ntawm tsob nroj ntau yam uas yog resistant mus rau lub pwm. Deleted kis tus kab mob tua thiab nplooj yog hlawv. Cov av ntawm lub kab thiab khawb nyob ib ncig ntawm lub bushes, whereupon nqa tsawv hnav khaub ncaws chiv (poov tshuaj thiab phosphorus-nitrogen).

Zoo tshwm sim muab sprayings tsis muaj zog tshuaj ntawm dej qab zib tshauv (0.5%) supplemented nrog zoo tib yam xab npum. Tsuag ob peb lub sij hawm: ua ntej flowering, tam sim ntawd tom qab, ua ntej sau (kaum hnub) thiab dua ob lub lis piam tom qab.

Yog hais tias powdery pwm no twb qhia nws tus kheej, kho lub cov nroj tsuag (ua ntej tshem tawm cov kab mob qhov chaw (nplooj thiab txawm twigs), ib tug fungicide. Txhais tau tias tshuaj, li ntawd, lub observance ntawm proportions thiab siv ntawm kev tiv thaiv cov khoom (hnab looj tes, qhov ncauj qhov ntswg) yog yuav tsum tau. Yuav ua li cas koj yuav nyeem tau rau hauv lub ntim.

Zoo muaj feem xyuam rau cov kev siv ntawm cov tshuaj "Topaz". Nws yuav tsum tau muab ob npaug rau ua, tab sis nws yog txaus rau tsuas yog ib qho (tom qab flowering)

Lwm cov tshuaj uas pab leg ntaubntawv kom tau ib tug kev hloov rau Bordeaux sib tov - "TSEV". Fab tsuag ua ntej flowering, raws li cov lus qhia.

Nyob rau hauv cov neeg kis tau "tsev kho mob": softened lub bar ntawm xab npum thiab 20 g ntawm sulfate bred nyob rau hauv ib lub thoob ntawm dej (10 L). Lim tshuaj matte xiav kho cov nroj tsuag tam sim ntawd tom qab flowering.

Nws muaj peev xwm yuav kho tau nrog ib tug daws ntawm tsev neeg xab npum (50 g) thiab dej qab zib (50 g) yaj nyob rau hauv ib lub thoob dej. Fab yog watered los ntawm ib tug watering tau nrog ib tug nplua lim ua ntej blooming nplooj (nyob rau hauv lub hav txwv yeem - peb litres ntawm cov tshuaj) thiab tom qab flowering.

Lwm, tsis dhau lub sij hawm-siv txoj kev yuav tsum tau 3 kg ntawm tshauv thiab ib lub thoob ntawm boiling dej (boiling dej nchuav tshauv). Txoj kev lis ntshav ntawm tshauv tsuag cov nroj tsuag ua ntej flowering thiab ces tom qab (luv ntawm hais txog kaum hnub).

Ntawm cov hoob kawm, ib zaug rau tag nrho cov zaub mov txawv yuav tsum tsis txhob siv - nws yuav tsum tau overkill, tsuas exacerbate qhov teeb meem no. Nws yog zoo dua mus xaiv ib tug ntau txoj kev tsim nyog. Feem ntau, nws yog uas ploj lawm ob kev kho mob rau ib lub xyoo. Tshwj xeeb tshaj yog, yog hais tias tus tsaws (los yog yub) uas koj xaiv yam uas yog resistant rau powdery pwm.

Thiab lwm yam tseem ceeb point: tus tshiab, tshiab khiv nrhav cov nroj tsuag, yuav tsum tau decontaminated. Qhov zoo tshaj plaws neeg sawv cev rau lub hom phiaj no pab raws li ib tug 1% tshuaj ntawm tooj liab sulfate. Seedlings yog khaws cia nyob rau hauv cov tshuaj no rau 5 feeb, ntxuav nrog dej thiab ces cog.
