Tomato yekutanga blight chirwere chakajairika chematomatisi, chinogona kuitika pakati nepakati uye pakupera nhanho dzemadomasi seedling, kazhinji mune yakakwira humidity uye kushaya simba kwechirwere chechirimwa, inogona kukuvadza mashizha, madzinde uye michero yemadomasi mushure mekuitika, uye kunyange kutungamirira kune yakakomba matamato mbesa.

1, tomato yekutanga blight inogona kuitika padanho rekudyara, saka tinofanira kuita basa rakanaka rekudzivirira pachine nguva.

2, kana chirimwa chikakanganiswa nenhamo, shizha rakawanda richaratidza kutsvuka, mavara matema, kukunguruka kwemashizha uye zvimwe zviratidzo, mune iyi nyaya, kurwisa chirwere chematomatisi kwakaderera, mabhakitiriya ekutanga echirwere anotora mukana wekutapukira kukanganisa.

3, matomatisi echirwere chepakutanga anotanga makwapa ebrown, dzimwe nguva pachange paine yellow halo yakatenderedza nzvimbo yacho, kusangana kwechirwere kunenge kuri pachena, chimiro chenzvimbo yacho chinowanzoita denderedzwa.

4, madomasi ekutanga blight kazhinji anotanga kubva kumashizha ezasi, uye zvishoma nezvishoma anopararira kumusoro, kunyanya mashizha ezasi haabviswe nenguva (kushanda chaiko kunonzwisisika zvichienderana nemamiriro ezvinhu, kazhinji kusiya mashizha maviri panzeve yemuchero) chirongwa chacho chiri nyore kuitika, nokuti munyaya iyi ichaita nzvimbo duku yakavharwa yakanyanyisa humidity, madomasi ekutanga blight uye zvimwe zvirwere zviri nyore kwazvo kuitika.

5, madomasi ekutanga blight inoitika pakati nepakati uye yekupedzisira nhanho yemashizha ichasanganiswa nenguva dzakasiyana dzechirwere makwapa, aya makwapa achatsemuka kana pakaoma.

6, matomatisi ekutanga blight mavara ari pakati uye ekupedzisira nhanho yevhiri pateni inooneka, iyo vhiri pateni ichaonekwa madiki matema, aya madiki madiki madiki ekutanga blight mabhakitiriya conidium, ane conidium, conidium inogona kuparadzirwa nemhepo, mvura, zvipembenene uye mamwe ma media kune hutano tishu zvinoramba zvichikuvadza.

7, mushure mekuitika kwechirwere chematomato chekutanga, kana kutonga kusina nguva kana nzira yekudzivirira isina kururama, chirwere chechirwere chichawedzera uye chozobatana nehombe.

8, yakabatana muchidimbu chekutanga blight, iyo tomato inosiya yakarasika basa.

9, Kufa kweshizha kunokonzerwa nekutanga blight kunogona kuonekwa mumufananidzo.

10.Tomato early blight inotungamira mukudhonzwa kwembesa.

Kudzivirira uye kurapwa kwekutanga blight yematomatisi

Kupisa kwekutanga kwematomatisi kunogona kudzorwa nenzira dzinotevera:

1.Mbeu nevhu kuuraya utachiona Usati washandura chirimwa, zvakasara zvemadomasi zvinofanira kucheneswa, uye ivhu rinofanira kubviswa utachiona.Mbeu dzematomatisi dzinodawo kucheneswa nemuto unodziya unonyoroveswa nekunyoroveswa nemishonga.

2, dzivisa munda wakavharwa humidity yakakwiriraBvisa mashizha ekare echikamu chepasi chematomatisi panguva yakakodzera uye inonzwisisika kuti uve nechokwadi chekuoma kwemunda uye kugadzira mamiriro asina kukodzera kuitika kwekutanga blight.

3, kunatsiridza kusabatwa nechirwere chematomatisiMaererano nehunhu hwemadomasi anoda fetereza nemvura, kuwedzera kwakaringana kwefetereza nemvura kunogona kuita kuti madomasi akure zvine hutano uye kuvandudza kugona kwematomatisi kurwisa dambudziko rekutanga.Uye zvakare, kushandiswa kwechirimwa immune activator senge activation protein yeyakanyanya chain chain spora inogona kunyatso kumisa immune system yematomatisi, uyezve kuvandudza kugona kwematomatisi kurwisa blight yekutanga kubva mukati kunze.

4, kusarudzwa kwakaringana kwevamiririri vekudzivirira nekudzoraPakutanga kwechirwere chepakutanga, echinyakare akawanda-saiti fungicides senge chlorothalonil, mancozeb uye gadziriro yemhangura inosarudzwa.Methylic acrylate fungicides yakadai sepyrimidon uye pyrimidon inogona kushandiswa.Pakati pekutanga kwechirwere, zvakakosha kuti ubvise chirwere chinorwara kutanga, uye wozoshandisa tsika dzakawanda-saiti fungicides + Pyrimidon/pyrimidon + phenacetocyclozole/pentazolol yekudzivirira nekudzora (compound gadziriro dzakadai sebenzotrimethuron, pentazole, fluorobacterium oximide, zvichingodaro), nechinguva chidiki chemazuva mana Ramba uchishandisa kanopfuura ka2, apo chirwere ichi chinodzorwa kune yakajairika manejimendi, kuve nechokwadi chekuti pfapfaidzo yakafanana uye inofunga.
