Mealy dew on petunias: kev tiv thaiv thiab tswj ntsuas

Nrog lub slightest yuam kev nyob rau hauv kev saib xyuas, kev sib tw petunia pib mob. Thawj thawj yeeb ncuab ntawm lub paj yog powdery mildew spores. Qhov txaus ntshai ntawm no tus kab mob fungal lies nyob rau hauv thawj zaug pib cov cim qhia - txawm thaum dawb Bloom tshwm rau ntawm nplooj, ntau growers ua yuam kev xav li plua plav. Vim lub sijhawm poob, cov nroj tsuag tuag taus. Yuav ua li cas thaum tus kaus poom me ntsis tshwm rau ntawm tus kab mob petunias, yam kev mob tshwm sim ntawm tus kab mob thiab txoj kev kho mob muaj nyob - qhov no yuav tham tom qab.

Dab tsi yog qhov txaus ntshai thiab qhov twg nws tuaj ntawm

Fungal mycelium, uas yog cov neeg ua hauj lwm hauv cov kab mob ntawm cov kab mob, nyob hauv cov av thiab ua rau lawv tus kheej tau hnov ​​ntawm cov kev mob thawj zaug rau lawv. Feem ntau cov cwj pwm txuam nrog rau kev ua kom muaj cov kab mob no yog cov huab cua txias thiab cov neeg pluag tsis zoo.

Koj puas paub? Petunia tau xub pom los ntawm botanists nyob rau hauv Uruguayan ib puag ncig thiab muab tso rau lub genus Tobacco. Yog li ntawd, lub paj yog Ameslikas hu ua Nicotiana axillaris.

Raws li cov kws txawj, ua rau txoj kev loj hlob ntawm powdery mildew foci tau:

  • ntau npaum li cas ntawm nitrogenous tshuaj nyob rau hauv lub paj lauj kaub;
  • tsis muaj qhov cua zoo ntawm cov nroj tsuag, uas yog tshwm sim los ntawm cov tuab tuab heev (xws li cov quav yuav tsum thinned);
  • tsis paub txog cov dej, thaum lub florist tso cai rau lub plhaub taum hauv av kom qhuav, thiab tom qab ntawd dauv nws nrog dej, los yog, ntawm qhov tsis sib xws, thaum nws moisturizes yam tsis tau tos pob hau ntais kom qhuav;
  • cov huab cua tsis zoo, thaum cua av qis tshaj 60%, ntawm qhov kub ntawm 15-25 ° C (qhov no ua rau tus kab mob no tsuas yog siv rau txoj kev petunias);
  • cov dej tsis huv;
  • neeg zej zog nrog cov nroj tsuag kab mob los yog kev sib cuag nrog tes uas tau chiv mob foci;
  • radical rejuvenation ntawm Bush;
  • Sudden kev hloov hauv kub;
  • kis los ntawm cua ntawm fungal microorganisms.

Nws tseem ceeb heev! Tus mob Petunias tau raug tua los ntawm sprinkling nrog tshwj xeeb npaj thiab watering. Nyob rau hauv rooj plaub ntawm sab hauv nroj tsuag, lub sill yog kho nrog ib tug sill, ib lub lauj kaub thiab ib phais.

Cov cim ntawm qhov tsos

Tus kab mob pib tshwm dawb plua plav tawg rau cov tub ntxhais hluas tua thiab hov ib feem ntawm cov nroj tsuag, thiab dhau lub sij hawm captures nws ua tiav. Ua ntej ntawm tag nrho cov, nplooj uas ze rau cov av yog cuam tshuam. Nyob rau hauv thawj theem ntawm fungal mycelium, me me ntawm noo noo yog noticeable nyob rau hauv no "plua plav". Yog hais tias koj saib zoo, ces nyob rau nplooj ntoos, qhov twg mycelium txuas, koj yuav saib tau me me ulcers, vim uas petunia txhua hnub ntau thiab ntau languishes. Koj yuav tsum tau ua raws li thawj cov tsos mob ntawm tus kab mob. Lwm yam, kab lis kev cai yuav txo kev tiv thaiv thiab rot yuav tsim.

Powdery mildew kuj raug mob ntawm sab hauv tsev (violets, orchids, Kalanchoe) thiab vaj paj (Roses, hydrangeas, asters, phloxes).

Kev tiv thaiv thiab kev cai agrotechnical

Nyob rau hauv thiaj li tsis xav contemplate dawb Bloom on nplooj ntawm petunia thiab ua txhaum koj lub taub hau tshaj li kho nws, koj yuav tau tshem ntawm fungi thiab cov kab mob resistant hybrids. Tab sis yog hais tias koj muaj lawv nrog kev puas tsuaj tag nrho ntawm cov cai ntawm cultivation, txawm tias genetic tiv thaiv yuav tsis txuag.

Nws tseem ceeb heev! Thaum pom ntawm nplooj ntawm petunia, lub mycelium powdery mildew nres lub paj los ntawm Txau thiab noj nrog nitrogen. Nws yog nqa deb ntawm lwm cov paj rau ib qho chaw tshav ntuj.

Yog li ntawd, muab kev cog lus tsim kho mob:

  1. Ua ib txoj cai: dej lub paj tsuas yog tom qab txheej sab saum toj ntawm lub substrate dries tawm. Dej rau moistening yuav tsum khom thiab sov so rau chav sov.
  2. Ib ntus thawm tawm ntawm pawg cog thiab txhua lub sijhawm tshem tawm cov tuag thiab nyob rau hauv kev sib txuas nrog hauv av nplooj.
  3. Tsis txhob overdo nws nrog nitrogen thaum fertilizing, lub sij hawm no yog tshwj xeeb tshaj yog tseem ceeb thaum lub sij hawm tsim ntawm peduncles.
  4. Tsis txhob neglect cov potassium-phosphate mixtures, uas cov kws txawj pom zoo rau txoj kev loj hlob ntawm lub cev tsis muaj zog ntawm lub paj.
  5. Tshawb xyuas cov stems thiab yoojyim txhua lub limtiam, them nqi tshwj xeeb rau hauv paus hauv paus.
  6. Periodically disinfect cov nroj tsuag nrog biofungicides.

Txoj kev ntawm nriaj tawm tsam "scourge"

Thaum nws lig dhau lawm los tiv thaiv kev tiv thaiv kev ntsuas thiab muaj kev pom tseeb ntawm kev mob ntawm lub paj, pib mus rau kev kho mob tam sim ntawd. Thawj qhov uas yuav tsum tau ua nyob rau hauv xws li ib qho teeb meem yog cais tawm lub thawv petunia los ntawm cov neeg nyob zoo. Txiav tawm tag nrho cov cheeb tsam uas cuam tshuam, txawm tias lawv tseem tsis tau muaj sij hawm qhib qhib. Cov residues no yuav tsum tau hlawv kom tsis txhob kis tus kab mob hauv lub vaj.

Nws tseem ceeb heev! Me me petunias, uas tawm tsam los ntawm powdery mildew, yog tag nrho dipped mus rau hauv kev kho mob daws. Yog li, ob qho tib si av thiab ntsuab loj yog disinfected.

Yog hais tias peb tham txog ib lub chav paj, ces nws yuav tsum tau transplanted rau hauv ib qho tshiab substrate. Ib tug hauv av ib ncig ntawm lub vaj teb petunias sprinkled nrog ib tug 2-cm txheej ntawm ntoo tshauv. Ntxiv dua ua mob ua ke nyob ntawm seb cov kab mob kis tau thiab koj nyiam. Koj tuaj yeem siv cov tshuaj tua pej xeem los tiv thaiv cov hmoov noom moj av los yog cov khoom ua paj ntoo.

Mealy dew infects orchards (currants, gooseberries, txiv hmab txiv ntoo, txiv duaj, txiv apples, txiv ntoo) thiab vaj teb cov qoob loo (cucumbers, txiv lws suav, zaub qhwv, carrots, zucchini, kav dej).

Cov zaub mov txawv

Cov kws paub txog kev paub cov tswv yim yuav tsum tau mus xyuas cov nyiaj no rau cov hom phiaj ntawm kev tiv thaiv thiab nyob rau theem pib ntawm tus kab mob. Yam ntxim saib ntxim ua ntxoov ntxaug yuav ua tau yog tias fungal mycelium tawm tsam koj tus hluas nkauj ntsuab tsis tshaj 4 hnub. Txwv tsis pub, txhua yam kev siv zog yuav tsis muaj txiaj ntsig.

Yog tias koj muaj sijhawm nrog cov hnub kawg, sim npaj kom muaj qhov sib tov "tawg taus" ntawm ntoo tshauv. Ua li no, koj yuav tsum tau tsuas yog 200 g ntawm cov khoom, 5 liv dej rhuab mus rau 40 ° C, thiab 30 g ntawm kua xab npum. Sib tov txhua yam zoo, cia nws zaum me ntsis. Sprinkle nrog ob-hnub interval thiab ua tib zoo soj ntsuam qhov mob ntawm cov nroj tsuag. Ntxiv rau, ntxiv 5 liv dej rau qhov seem uas yog tov thiab ncuav dhau qhov dej.

Koj puas paub? Lub asteroid, uas tau pom nyob rau hauv 1921, yog lub npe hu ua tom qab paj.

Ib qho kev daws teeb meem yog iodine tov, uas yog npaj rau hauv ib qho ntawm 1 ml / 1 l. Dej qab zib tsho kuj muaj kev nyhav dhau los. 10 g ntawm hmoov ib 2 liv dej kub thiab 1 teaspoon ntawm kua xab npum yog txaus rau kev kho lub kab lis kev cai peb zaug nrog ib lub lim tiam caij nyoog. Qij los yog cov dos hauv tandem nrog dej kub thiab iodine muab cov txiaj ntsig zoo. Lub ntsiab lus ntawm qhov kev xav tau yog qhov yuav tsum tau hais kom haum rau 48 xuab moos. Thaum twg lub cuab tam npaj txhij, lub nroj tsuag yuav xav tau ntau cov yeeb tshuaj.

Yuav kom tiv thaiv kom txhob kis tau thiab ua kom cov fungal mycelium yog tau nrog ib qho kev daws ntawm poov tshuaj permanganate (poov tshuaj permanganate), mis nyuj thiab whey. Nyob hauv kev xyuas, cov neeg cog khoob ntsej muag cov ntawv pov thawj ntawm cov saum toj no thiab txawm muab piv nrog cov paub txog fungicides. Piv txwv li, lawv sau hais tias cov tshuaj "Phenarimol" thiab "Benomil" poob rau hauv cov hauj lwm zoo nrog cov mis nyuj nrog dej hauv ib qho ntawm 1:10.

Koj puas paub? Cov neeg ua teb txawv teb chaws uas tshwj xeeb hauv cov khoom noj khoom haus zoo xav cov khoom siv mis los txhaws nrog cov hmoov mothew.
