Wageningen University & Research (WUR) ifufuza mitundu ya mbatata zakutchire kuti ithe kulimbana ndi matenda osiyanasiyana ndi tizirombo ta mbatata.
Njira yotakata imeneyi imapangitsa kuti mitundu ya mbatata yopanda matenda ipangike yomwe ingapangitse kuti mbatata zizikhala zokhazikika padziko lonse lapansi. Kafukufukuyu akuyitanidwa ndi Holland Innovative Potato (HIP) ndi Unduna wa Zaulimi, Zachilengedwe ndi Zakudya Zabwino (LNV).
Mbatata imatseka kuzungulira
Kupezeka kwa nthaka yachonde ndi madzi abwino okwanira pakusintha kwanyengo ndizovuta zomwe tiyenera kuthana nazo mzaka zikubwerazi. Mbatata imatha kugwira ntchito yayikulu chifukwa ndi mbewu yothandiza kwambiri popanga chakudya ndi mafakitale potengera madzi ndi nthaka. Kuphatikiza apo, mbatata imakhala ndi mapuloteni ambiri, chakudya, mavitamini ndi michere, zomwe zimapangitsa kukhala ndi thanzi labwino. Njira zatsopano za kuswana ndi kukonza zakhala zikupezeka m'zaka zaposachedwa ndipo zimapangitsa mbatata kukhala mbewu yofunikira kukwaniritsa zosowa zopanga chakudya chabwino komanso chokhazikika.
Kuchepetsa kuwongolera mankhwala
Kulima mbatata nthawi zonse kumawopsezedwa ndi matenda ambiri ndi tizirombo. Mankhwala ambiri ophera tizilombo akugwiritsidwa ntchito pakadali pano pakufuna mbatata. M'zaka zaposachedwa, kulimbikira kwachitika kuti athane ndi matenda akulu a mbatata omwe amayambitsidwa ndi Phytophthora popanga mitundu yolimbana. Zotsatira zake, kugwiritsa ntchito mankhwala ophera tizilombo kutsutsana ndi matendawa kudzachepa kwambiri m'zaka zikubwerazi. Kuteteza mbewu pang'ono mophatikiza ndi kutentha kwambiri komanso kusiyanasiyana kwamvula chifukwa cha kusintha kwa nyengo, kumabweretsa kuwonjezeka kwa matenda ena ndi tizirombo.
Kulimbana ndi mitundu ya mbatata zakutchire
Matenda enawa ndi tizilombo tina timayamba chifukwa cha bakiteriya, bowa, mavairasi, ma nematode ndi tizilombo, mpaka pano sanalandiridwe chidwi kwenikweni. Wageningen University & Research (WUR) ikufufuza mitundu ya mbatata zakutchire za HIP kuti zitsutse tizilombo toyambitsa matendawa. Mitundu ina yamtchire yothandiza yapezeka kale pakuwunika koyamba.
Mitundu yosagonjetseka ikufufuzidwanso ndi WUR ndipo idzagwiritsidwa ntchito ndi makampani obereketsa omwe ali ndi HIP kuti apange mitundu yatsopano. Cholinga chachikulu ndicho kulima mozungulira mozungulira pogwiritsa ntchito mitundu yopanda matenda.
