Chiwopsezo cha matenda obwera chifukwa cha zomera chawonjezeka kwambiri pamene kutentha kwa dziko ndi malonda a mayiko akuwonjezeka. Mbatata zakuda ndi zofewa zomwe zimayambitsidwa ndi gulu la mabakiteriya a banja la Pectobacteriaceae ndi genera. Dickey ndi Pectobacteria ndi matenda ofunikira omwe amabweretsa kuwonongeka kwachuma padziko lonse lapansi. Ku European Union, iwo amalamulidwa ndi tizirombo tomwe sitikhala kwaokha. Mitundu isanu yomwe imadziwika kuti imayambitsa zizindikiro za blackleg pa mbatata zomwe sizimadziwika. Kwa zaka zambiri, P. atrosepticum Amakhala tizilombo toyambitsa matenda a mbatata m'madera ozizira otentha a ku Ulaya ndi North America, zomwe zimayambitsa matenda a blackleg. Komabe, posachedwapa zamoyo zingapo zatsopano, zosadziwika ku Northern Europe, zatuluka monga tizilombo toyambitsa matenda. Imodzi mwa mitundu iyi ndi D.solani. Ku Finland, D.solani idapezeka koyamba mu 2004 ndipo yakhala ikuyambitsa miliri yayikulu ya blackleg ku Finland kwazaka zopitilira khumi. Dziko la Finland ndi limodzi mwa mayiko asanu ku Ulaya (Germany, England, Ireland ndi Azores Archipelago ku Portugal) omwe amapatsidwa mwayi wapamwamba wolima mbatata. Lingaliro la udindo wa High-Grade ndi udindo wogwiritsa ntchito njira zolimba kuti deralo lisalowedwe ndi tizirombo toopsa komanso tizilombo toyambitsa matenda a mbatata. Zina mwa njirazi ndi monga kulamula katengedwe ka mbeu ya mbatata kumadera amenewa, kugwiritsa ntchito mbeu za certified yapamwamba polima mbatata m’chigawochi komanso kuchepetsa kuchuluka kwa minda ya mbatata (dera) m’madera osankhidwa a High-Grade.
Mgwirizano wogwira ntchito komanso mgwirizano womwe udakhazikitsidwa pakati pa makampani aku Finland omwe amatumiza ndi kupanga mbewu za mbatata ku Finland ndi omwe akumayiko ena akutumiza mitundu ya mbewu ku Finland adakhazikitsa njira yofunika kwambiri yoletsa kufalikira kwa mbewu. D.solani ku Finland popeza nthawi zambiri malonda aulere (kutumiza / kutumiza kunja) ndiye njira yayikulu yokhazikitsira blackleg Pectobacteriaceae kupita kugawo latsopano.
