Fusarium unoda kuti madomasi - chirwere iri nyore kudzivirira pane mushonga

Vazhinji Chikwata vanokura madomasi mu greenhouses kana kusango ari oga panyika, atarisana ndechokuti pakakwirira yose miriwo anosiya curl they ezasi kutendeuka yeyero uye kufa. Vachiona uyu mufananidzo, vamwe vanosarudza kuti zviri kushayikwa kwezvokudya, vamwe anoratidza zvinoitwa tupembenene nevamwe - siyana zvirwere. Munhu wose ari kuedza kuita chinhu kuti arege kurasikirwa yokukohwa. Mumamiriro ezvinhu akadaro zvakakosha kumisa mhaka uye kwete mwaya riri pedo, achitarisira kuti kushandisa zvinodhaka kuchigadzira.

Munguva ichangopfuura, kwakapararira Fusarium unoda kuti domatisi. The mapikicha munyaya ino inoratidza sei migumisiro tarira zvinoitwa kuti pathogenic notumwe genus pamusoro Fusarium, iyo inouyisa chirwere. On chikamu hosha chirimwa pedyo mudzi zvakajeka kuonekwa mhete rima. Dzimwe nguva mujinga hunde pane chiedza grey kana chichena Negima unhani.

Kare, Fusarium unoda kuti domatisi yaiitwa chete munzvimbo with hot yechirimo, uye zvino kunoratidzwa muna dzinodziya dzinodengenyeka, sezvo nzvimbo idzi vari kuramba akasika zvinhu nokuda kwayo kukura.

Sources uye vatakuri chirwere ndivo mbeu utachiona, ivhu uye perennial rekushongedzesa. The spores of chakuvhe - utachiona hwakakura - refu vari ivhu uye zvisaririra zvinomera akafa. Kana chirimwa kutapata romuzvarirwo, hosha hakuiti unooneka. Zvisinei, yaivhuvhuta ezvinhu uye kunetseka ezvinhu (kuchinja kamwe kamwe ari unyoro uye ivhu tembiricha uye mhepo pachisara mwando, kuoma nechando, ivhu muviri kushaikwa, etc.) kubatsira kukura kwezvirwere zvakadai Fusarium unoda kuti domatisi.

Mugumisiro kukura pasi kunetseka ezvinhu ari kare akacherekedza infiltration pamusoro pathogenic notumwe vari midzi, uye kubva ipapo mukati pedyo chikamu domatisi hunde. Huchiwedzera kuburikidza vascular hurongwa, asi chakuvhe inobata kwete chete madzinde, asiwo muchero. Panyaya iyi, misoro miti droop, mashizha kuva flaccid uye mudzokere yero, unoda uye ipapo iome. Mune zvimwe zviitiko, pangave vakawanda kudzvinyirirwa miti zvibereko diki. Simba miti vakazoroorwa chinobata kwemabhakitiriya nenyunje, uye vanofa.

Fusarium unoda kuti madomasi kunogona kuitika chero padanho kukura. Nhungirwa, zviri pamwe mudzi mudzi rots. Akura chokutambudzika cotyledons mizambiringa yakabva kumwe vanotanga kupera. Zvinoitika kuti madomasi sezvinooneka utano vane Isimba rakadini rinogona kubudiswa chirwere. In chimiro ichi, zviratidzo pachena pava paya nzendo pakukura. Kana mizambiringa yakabva kumwe vanofanira utano, uye munguva Mwaka wokukura akaratidza zviratidzo chirwere, zvinganzi vaifungidzira kuti ivhu utachiona.

Asati yokudyara potting ivhu rinofanira disinfected. Kuti aite izvi, shandisa utachiona chigadzirwa "Trihodermin". The bhokisi Kukura 30x50 zvinofanira akapinda magiramu 4 chete kudzivirira mizambiringa yakabva kumwe kurwisa zvirwere zvakadai Fusarium unoda kuti domatisi. Kurapwa chero rwakazara kuti basa, sezvo kudzivirira anogara nyatsoshanda.

Kudzivirira chirwere panguva uswa , zvinomera vanofanira kuva 4 nguva por mwaka mvura mhinduro pamusoro vakati zvinodhaka, rakasanganiswa mune nhamba 7 magiramu kuti upfu kusvika 2 litres mvura. 500 ml ichi mhinduro zvaidiwa chirimwa chimwe nechimwe dira. Uyezve, madomasi zvinogona sprayed pamusoro mashizha zvinodhaka "Falcon" pane wevasungwa 1 MG pa 3,3 fő mvura.

Fusarium unoda kuti madomasi - a fungal chirwere kuti kwakaoma zvisingaiti kurwa, uye zviri nyore kudzivirira. Unoda kuwana goho rakanaka - kwete usimbe kuita matanho.
