FASFC: Matanho ekurwisa kuora kwebrown muBelgian

Matanho ekurwisa kuora kwebhuruu mumatunhu eAntwerp neLimburg

Brown rot is a disease caused by the bacterium Ralstonia solanacearum and mainly affects potato cultivation. This bacterium has already been found in watercourses in the provinces of Antwerp and Limburg and unfortunately can no longer be eradicated there.

Nekuda kwenjodzi yekushatiswa kwekurimwa kwembatatisi kuburikidza nemvura yepadenga, varimi vanobva kune mamwe maseruya mumatunhu aya vanosungirwa kutora matanho ekudzivirira. Iyo bhakitiriya inongokanganisa dzimwe mhando dzemiti uye haina kuendeswa kuvanhu.

Mahekita zviuru zana, ndiyo nzvimbo inorimwa mbatatisi muBelgium. Iyo FASFC, ichishanda pamwe nematunhu nevarimi, inonyatso tarisa zvirimwa izvi kuitira kuona kuputika kwezvipembenene zvega zvega kubva padanho rekutanga uye, kana zvichidikanwa, zvinopedza. Mu100,000, iyo FASFC yakatora 2019 sampuli yakaongororwa sechikamu chekutarisa uku.

Belgian potato cultivation has remained free of brown rot in recent years, but the bacterium Ralstonia solanacearum is still present in watercourses in the provinces of Antwerp and Limburg. It is impossible to eradicate this bacteria in surface water. The only way to prevent outbreaks in potato cultivation is therefore to strictly apply the protective measures. When the bacterium is discovered in potatoes (both seed and ware potatoes), in addition to other measures, a ban on planting these lots is imposed and it is mandatory to process these lots only under quarantine conditions. If these obligations are not complied with, the potatoes can be destroyed.

Zvinotarisirwa matanho ekudzivirira

Vese varimi vembatatisi kubva ku 45 matunhu akabatanidzwa (PDF) inofanirwa kutevedzera matanho ekudzivirira. Pasina mamiriro ezvinhu havagone kushandisa mvura yemvura pamusoro kudiridza kana zvimwe zvinangwa zvekurima mbatatisi, matomatisi uye maabergines.

Pamusoro pezviyero zvekudzivirira, chero nzvimbo yakarimwa ine nzvimbo inopfuura gumi ares inofanirawo kuziviswa. Kubva gore rino, chirevo kuFASFC hachichadiwe kana murimi atoita zvakadaro kuFlemish Region mune mamiriro eprimiyamu yeCAP (hapana nzvimbo dzekuchengetedza dzinoshanda kuWalloon Dunhu).

Dzvanya apa kuti uwane rumwe ruzivo nezve izvo zvinomanikidzwa kudzivirira.

Varimi vembatatisi vanogona kubata FASFC kuburikidza neLocal Control Unit (LCE) iyo yavanowira pasi payo.

Varimi vese vanobatanidzwa vanosungirwa kutevedzera zviyero izvi. Ivo vanogona neimwe nzira kuve nemhosva zvizere kana paitika kusvibiswa. Pakadaro, kodzero yemubhadharo inogona kukanganiswa (Royal Dare remusi wa5 Zvita 2004 ichisimbisa mipiro yechinguvana yezvikwereti inokweretwa nevarimi vembatatisi kuripira kurasikirwa nekuda kwezviyero zvinorwisa zvipuka zvinokuvadza).

Zviratidzo zvinogona kuoneka pazera ripi zvaro rekurima uye zvinosanganisira kuoma uye kuita yero kwemashizha uye kumira kwemiti. Hosha dzinogona kuve dzakakora mumiti midiki, inotapira uye inogona kuoneka seinokurumidza kusvava mashizha nekudonha kwematemu. Pakutanga, hunde imwe chete inogona kusvava. Kana mamiriro akakwana, mashizha ese muchikomo anogona kuoma nekukurumidza asi osara ari girini. Mashina anogona kuoneka aine mitsetse sehutachiona hwehutachiona hunowoneka. 

 Tuber vascular tishu inowanzo kuve yakasviba grey brown, uye iyo discoloration inogona kuwedzera kuita iyo pith kana cortex. Tuber maziso anoshanduka kuita grey brown, uye inonamira exudate inogona kuumba pameso kana panowanikwa stolon kune iyo tuber. Pakupedzisira, hutachiona hutachiona hwakasiiwa muvhu hunozoshanduka kuita huremu hutete hwakakomberedzwa netaundi rakatetepa rekunze uye periderm
