Fusarium mufuna zomera: chiyambire matendawa

mufuna Fusarium, Fusarium, kapena - ndi matenda a mafangasi matenda imagwira zosiyanasiyana mbewu. Kuyambitsa wothandizila ake a mafangasi etiology (opanda ungwiro bowa Fusarium), lomwe chikhalidwe, pali pafupifupi 70 mitundu. Iwo akhoza zimapezeka monga majeremusi kapena semiparasites, saprophytes kapena symbionts Komabe, maphunziro yaitali asonyeza kuti matendawa amakhudza makamaka zomera, wofooka chifukwa zinthu zina.

Tizilomboti zambiri kulowa mpesa mwa dongosolo muzu ndipo kenako chifukwa ikutha ake. Mwa dongosolo mtima akufotokozera yaikulu ramified mycelium, kotero kuti mbewu akhudzidwa afa. mufuna Fusarium kusiyana kwambiri mofulumira kwenikweni izo zikuchitika masiku angapo pambuyo matenda.

Matendawa kufalikira mu mabacteria onse nyengo. Mu dziko lathu ambiri kumwera, kum'mwera chakum'mawa kapena mu zigawo Far East. Pafupifupi zaka zambiri akumane zokolola za mbewu zosiyanasiyana zikhoza kuchepetsedwa ndi 40%.

mufuna Fusarium wa nkhaka pa siteji Woyamba anapezeka ndi pamwamba yoweramitsidwa mu maola yotentha. Ngati matenda yakula, mbewu umafota kwathunthu ndi yomweyo. Amadwala dongosolo muzu - pa pomwepo kenaka waukulu akamwalira, koma nthambi pambali pang'ono kukhala yotheka.

Mu phwetekere mufuna Fusarium akuyamba ndi kusintha mtundu wa masamba m'munsi. Iwo amakhala chlorotic ndi wilted. Ndi chitukuko cha matenda limasintha mtundu wa mitsempha - iwo kukhala mtundu bulauni. Pang'onopang'ono anayamba kufa masamba onse, necrosis akuwonekera.

Fusarium mufuna wa sitiroberi imayamba ndi lifotabe minofu pa nsonga ya masamba ang'ono ndi wilting. Ndiyeno nkutembenuka mapesi zofiirira ndi masamba, ndi Rosette wotaya elasticity ndi likuphwasuka. Mwina kuvunda pa chinyezi mkulu. Kwathunthu chomera akamwalira pambuyo pafupifupi 1.5 miyezi.

Ambiri, tingathe kuona kuti Fusarium Mufuna angayambe pa siteji iliyonse ya kayendedwe ka zomera, koma nthawi zambiri amapezeka pa nthawi maluwa.

Kodi matenda

Ndiwo matenda - nthaka zakhudzana. Choncho, ambiri amavutika zomera mu wowonjezera kutentha, kumene nthaka sasintha ndipo alibe ntchito kasinthasintha. Chifukwa china pakutchulidwa wa Fusarium - kachilombo mbewu. Bowa kukhala ndi kukula pamodzi ndi zomera, ndiyeno amuphe.

Fusarium mufuna: Kupewa ndi matenda

Etching zakuthupi kubzala chingamulepheretse n'zotheka kulowa tizilombo toyambitsa matenda pa kama wa mbewu. Good nthaka kukumba, kupalira m'malo a gawo lapansi kasinthasintha ndi tizirombo pa zipangizo ndi kukhala ndi kuchepa kuthekera yatsoka matenda. Bowa kukula bwino pa mkulu kutentha mpweya (za 28 ° C), chinyezi mkulu ndi waufupi photoperiod. Choncho, muyenera bwino podutsa mpweya greenhouses. Monga kukonzekereratu ndi zofunika kamodzi pa sabata kuyendera mabedi ndikupeza zomera kachilombo. toyesa matenda achotsedwa ndi kutentha. zotsatira zabwino posonyeza chisanadze steaming wa nthaka ndi disinfection ake ndi nthumwi yapadera kwachilengedwenso pamaziko a muzikangana mafangasi. "Privekur" angagwiritsidwe ntchito mankhwala.
