Sezvineiwo, kunyangwe ichipa kutyisidzira kukuru kumatatisi machubhu, maitiro ayo pamashizha embatatisi akanyanya kuderera.
Imwe yemhando inosiyanisa yeUS-23 dhizaini kugadzirwa kwayo kwakanyanya kwesporangia pamadomasi. Izvi zvinoita kuti zvipararire nyore nyore nemhepo, zvichikwanisa kuparadzira utachiona panzvimbo hombe munguva pfupi.

Kune avo vari kubata nekunonoka blight muzvirimwa zvavo, zvakakosha kuti vagare vaine ruzivo nezvezvichangobva kuitika uye maitiro anokurudzirwa. Dr. Willbur aripo kuti apindure mibvunzo nekupa nhungamiro. Anogona kuwanikwa kuburikidza neemail pa willbur1@msu.edu.
Mukupedzisa, kusimbiswa kwekupedzisira blight muSouthwestern Ontario chiyeuchidzo chakasimba chematambudziko akatarisana mukurima kwemazuva ano. Nekunzwisisa kutyisidzira chaiko kunounzwa neUS-23 strain uye nekushandisa nzira dzekutonga dzinoshanda, varimi nenyanzvi dzekurima vanogona kushanda pamwechete kuchengetedza zvirimwa zvavo uye kuona chikafu chakagadzikana.
