Kuwonongeka kwa phwetekere koyambirira ndi matenda wamba a tomato, omwe amatha kuchitika pakati komanso mochedwa magawo a mbande ya phwetekere, makamaka pakakhala chinyezi chambiri komanso kukana matenda ofooka, amatha kuvulaza masamba, zimayambira ndi zipatso za tomato zitachitika, ndipo ngakhale kuyambitsa mbande zazikulu za phwetekere.

1, phwetekere choipitsa oyambirira akhoza kuchitika pa mmera siteji, choncho tiyenera kuchita ntchito yabwino kupewa pasadakhale.

2, pamene chomera chikukhudzidwa ndi mavuto, tsamba lonse lidzawonetsa chikasu, mawanga amdima, kupukuta masamba ndi zizindikiro zina, pamenepa, kukana kwa phwetekere kumachepa, mabakiteriya oyambirira amatenga mwayi wowononga kuwonongeka.

3, phwetekere matenda oyambirira mawanga oyambirira bulauni mawanga, nthawi zina padzakhala chikasu Halo kuzungulira malowo, mphambano matenda ndi zoonekeratu, mawonekedwe a malo nthawi zambiri zozungulira.

4, phwetekere choipitsa choyambilira nthawi zambiri chimayamba kuchokera m'munsi masamba, ndiyeno pang'onopang'ono chimafalikira m'mwamba, makamaka masamba otsika samachotsedwa munthawi yake (ntchito yeniyeniyo ndi yololera malinga ndi momwe zilili, nthawi zambiri amasiya masamba awiri pa khutu la zipatso) chiwembu n'zosavuta kuchitika, chifukwa mu nkhani iyi adzapanga malo ang'onoang'ono cha kutsekedwa mkulu chinyezi, phwetekere choipitsa oyambirira ndi matenda ena n'zosavuta kwambiri.

5, phwetekere oyambirira choipitsa amapezeka pakati ndi mochedwa magawo masamba adzakhala wothira nthawi zosiyanasiyana matenda mawanga, mawanga adzaswa pa nkhani youma.

6, phwetekere oyambirira choipitsa mawanga pakati ndi mochedwa siteji ya chitsanzo gudumu likuwonekera, chitsanzo gudumu adzaoneka ang'onoang'ono mawanga wakuda, mawanga ang'onoang'ono wakuda ndi oyambirira choipitsa mabakiteriya conidium, amene ali conidium, conidium akhoza kufalikira ndi mpweya, madzi, tizilombo ndi zofalitsa zina ku minofu yathanzi zikupitiriza kuvulaza.

7, pambuyo pa zochitika za phwetekere oyambirira matenda, ngati ulamuliro si yake kapena njira kupewa si zolondola, matenda malo adzakulitsa ndiyeno agwirizane mu lalikulu.

8, olumikizidwa mu chidutswa cha choipitsa oyambirira, phwetekere masamba kwenikweni anataya ntchito.

9, Kufa kwamasamba komwe kumachitika chifukwa cha kuvulala koyambirira kumawoneka pachithunzichi.

10.phwetekere koyambirira choipitsa kumabweretsa mmera kukoka.

Kupewa ndi kuchiza oyambirira choipitsa wa phwetekere

Kuwonongeka koyambirira kwa tomato kungathe kulamuliridwa ndi njira zotsatirazi:

1.Kuphera tizilombo toyambitsa matenda ku Mbewu ndi nthaka Musanasinthe mbewu, zotsalira za phwetekere ziyenera kutsukidwa, ndipo nthaka iyenera kupha tizilombo toyambitsa matenda.Mbeu za phwetekere zimafunikanso kutetezedwa ndi tizilombo toyambitsa matenda ndi sopo wotentha komanso kuthira mankhwala.

2, pewani munda womwe watsekedwa chinyezi Chotsani masamba akale a m'munsi mwa phwetekere munthawi yake komanso moyenera kuti mutsimikizire kuuma kwamunda ndikupanga zinthu zomwe sizoyenera kuchitika koyambirira kwa choipitsa.

3, onjezerani phwetekere kulimbana ndi matenda Molingana ndi momwe phwetekere amafunikira feteleza ndi madzi, feteleza wokwanira wamadzi ndi madzi amatha kuonetsetsa kuti phwetekere ikule bwino komanso kuti phwetekere amatha kulimbana ndi choyipitsa choyambirira.Kuphatikiza apo, kugwiritsa ntchito ma activator a chitetezo chamthupi monga ma activation a protein ya unyolo wabwino kwambiri wa spora amatha kuyambitsa chitetezo chamthupi cha phwetekere, ndiyeno kukulitsa luso la phwetekere kukana choipitsa choyambirira kuchokera mkati.

4, kusankha kolondola kwa zida zopewera ndi kuwongoleraMatenda atangoyamba kumene, mankhwala opha mafangasi opezeka m'malo osiyanasiyana monga chlorothalonil, mancozeb ndi mkuwa amasankhidwa.Methylic acrylate fungicides monga pyrimidon ndi pyrimidon angagwiritsidwe ntchito.Kumayambiriro kwa matenda, m'pofunika kuchotsa minofu ya matenda poyamba, ndiyeno mugwiritse ntchito mankhwala ophera tizilombo toyambitsa matenda osiyanasiyana + Pyrimidon/pyrimidon + phenacetocyclozole/pentazolol pofuna kupewa ndi kulamulira (mankhwala okonzekera monga benzotrimethuron, pentazole, fluorobacterium oximide), etc.), ndi nthawi ya masiku 4 Pitirizani kugwiritsa ntchito nthawi zoposa 2, pamene matendawa akuyang'aniridwa ndi kayendetsedwe kabwino, kuonetsetsa kuti kupopera ndi yunifolomu komanso moganizira.
