Kuipitsa bakiteriya wa soya ndi matenda owononga mbewu omwe amakhudza mbewu za soya padziko lonse lapansi.Matendawa amayamba ndi bakiteriya yotchedwa Pseudomonas syringae PV.Nyemba za soya zimatha kutaya zokolola kwambiri ngati sizitsatiridwa.Alimi komanso akatswiri a zaulimi akhala akufufuza njira zabwino zothanirana ndi matendawa komanso kupulumutsa mbewu zawo za soya.M'nkhaniyi, tikufufuza mankhwala ophera fungicides streptomycin, pyraclostrobin, ndi copper oxychloride ndi kuthekera kwawo pochiza choipitsa cha bakiteriya wa soya.

Streptomycin ndi mankhwala ambiri omwe amagwiritsidwa ntchito ngati mankhwala opha tizilombo mwa anthu.Komabe, imagwiritsidwanso ntchito ngati mankhwala ophera tizilombo.Streptomycin ili ndi antimicrobial properties ndipo imagwira ntchito poletsa mabakiteriya, bowa ndi ndere.Pankhani ya choipitsa cha bakiteriya wa soya, streptomycin yawonetsa zotsatira zabwino pothana ndi mabakiteriya omwe amayambitsa matendawa.Itha kugwiritsidwa ntchito ngati utsi wa foliar kuti muchepetse kuopsa komanso kufalikira kwa matenda.Streptomycin imathanso kuwongolera matenda a bakiteriya ndi mafangasi a mbewu zina zosiyanasiyana, komanso kukula kwa algae m'mayiwe okongola ndi m'madzi am'madzi.

 

Copper oxychloridendi mankhwala ena ophera bowa omwe amagwiritsidwa ntchito kwambiri paulimi kuthana ndi matenda oyamba ndi fungus ndi mabakiteriya mu mbewu za zipatso ndi masamba, kuphatikiza soya.Ndiwothandiza makamaka ku matenda monga choipitsa, nkhungu, ndi mawanga a masamba.Copper oxychloride yawonetsedwa kuti imagwira ntchito motsutsana ndi Pseudomonas syringae pv.Soya, chomwe chimayambitsa matenda a bakiteriya a soya.Akagwiritsidwa ntchito ngati kupopera, fungicide iyi imapanga chitetezo pamalo a zomera, kuteteza kukula ndi kufalikira kwa tizilombo toyambitsa matenda.Kuthekera kwake kupereka chitetezo chokhalitsa kumapangitsa kukhala chisankho chabwino kwambiri popewa komanso kuchiza choipitsa cha mabakiteriya a soya.

Pyraclostrobinndi fungicide yomwe imagwiritsidwa ntchito kwambiri paulimi ndipo imagwiritsidwa ntchito kwambiri pothana ndi matenda osiyanasiyana a zomera.Fungicide ndi ya mankhwala a strobilurin ndipo imakhala yothandiza kwambiri polimbana ndi tizilombo toyambitsa matenda.Pyraclostrobin imagwira ntchito poletsa kupuma kwa maselo a mafangasi, ndikulepheretsa kukula kwawo ndi kubereka.Ngakhale kuti pyraclostrobin sangayang'ane mwachindunji mabakiteriya omwe amachititsa kuti mabakiteriya a soya awonongeke, awonetsedwa kuti ali ndi machitidwe omwe amatha kuchepetsa kuopsa kwa matenda.Kukhoza kwake kuthana ndi matenda ena oyamba ndi mafangasi a mbewu za soya kumapangitsa kukhala chida chofunikira kwambiri pakuwongolera matenda.

Posankha mankhwala ophera tizilombo toyambitsa matenda a soya, zinthu monga mphamvu, chitetezo, ndi kukhudzidwa kwa chilengedwe ziyenera kuganiziridwa.Streptomycin, copper oxychloride, ndi pyraclostrobin zonse ndi njira zothandiza polimbana ndi matenda owonongawa.Komabe, kusankha kwa fungicides kuyenera kufunsidwa ndi akatswiri a zaulimi, malinga ndi momwe mbewu za soya zimakhalira.Kuphatikiza apo, ndikofunikira kutsatira mitengo yovomerezeka yogwiritsira ntchito komanso njira zodzitetezera kuti muchepetse zoopsa zilizonse zomwe zingachitike pogwiritsa ntchito mankhwalawa.

 

Pomaliza, kuwonongeka kwa bakiteriya ku soya ndizovuta kwambiri kwa alimi a soya ndipo mankhwala ophera bowa amatha kutenga gawo lofunikira pakuwongolera kwake.Streptomycin, copper oxychloride, ndi pyraclostrobin onse ndi mankhwala omwe ali ndi kuthekera kothana ndi matendawa.Komabe, zinthu monga mphamvu, chitetezo, ndi kukhudzidwa kwa chilengedwe ziyenera kuganiziridwa posankha mankhwala oyenera kwambiri othana ndi vuto la kuwononga mabakiteriya a soya.Pokhazikitsa njira zophatikizira zothana ndi matenda komanso kugwiritsa ntchito mankhwala opha bowa, alimi amatha kuteteza mbewu za soya ndikuonetsetsa kuti zakolola bwino.
