Mphere wa tirigu ndi matenda ofala padziko lonse lapansi, omwe makamaka amayambitsa choipitsa mbande, kuwola kwa khutu, zowola tsinde, zowola ndi makutu.imatha kuwonongeka kuyambira mbande kupita kumutu, ndipo chowopsa kwambiri ndi kuvunda kwa khutu, komwe ndi matenda oopsa kwambiri a tirigu.

Ndi ma fungicides ati omwe angagwiritsidwe ntchito kuwongolera?

Carbendazim ndi mtundu wa benzimidazole fungicide, womwe umagwira ntchito ku ascomycetes ambiri ndi Deuteromycetes.Chifukwa chake, carbendazim imakhudza kwambiri nkhanambo ya tirigu.Ndi mankhwala oyamba achikhalidwe kuletsa nkhanambo ya tirigu ndi mtengo wotsika.

Thiophanate methyl, ngati carbendazim, ndi mtundu wa benzimidazole fungicide.Ikhoza kusinthidwa kukhala carbendazim mu zomera, zomwe zimasokoneza mapangidwe a thupi la spindle ndi magawano a maselo.Chifukwa chake, makina ake owongolera ndi ofanana ndi carbendazim, koma poyerekeza ndi carbendazim, imakhala ndi mayamwidwe amphamvu komanso okhalitsa.Kwa zomera zomwe zili ndi kachilombo, mphamvu yolamulira inali yabwino kuposa carbendazim.

Tebuconazole ali ndi mphamvu yolamulira pa powdery mildew, dzimbiri ndi matenda ena.Tebuconazole ndi mankhwala othandiza komanso oyenera kuwongolera nkhanambo ya tirigu.Kugwiritsa ntchito moyenera Tebuconazole kumakhudza bwino nkhanambo ya tirigu, ndipo ndi imodzi mwa mankhwala opha fungicides othana ndi nkhanambo ya tirigu.

Kupyolera mu kuphatikiza kwa zinthu zosiyanasiyana zogwira ntchito, ndi njira yodziwika bwino komanso yolunjika yochepetsera nkhanambo ya tirigu, ndipo imatha kuchedwetsa kukula kwa fungicide kukana.

Mankhwala ophatikizika omwe ali ndi mphamvu zambiri pa nkhanambo ya tirigu ndiwowonjezera mphamvu ku mankhwala ophera tizilombo toyambitsa matenda a nkhanambo.
