Late blight inokonzerwa nefungus Phytophthora infestans, iyo inogona kukurumidza kupararira nekuparadza zvirimwa zvese. Maererano neruzivo rwazvino, chirwere ichi chinodyira varimi pasi rose mabhiriyoni emadhora mukurasikirwa gore rega rega. Asi masayendisiti awana nzira itsva inokatyamadza yekurwisa kunonoka kupera: nekushandisa musanganiswa unongoitika wega unowanikwa mumashizha ezvimwe zvirimwa.
Komboni iyi, inodaidzwa kuti compound beta-caryophyllene (BCP), yakawanikwa ichimisikidza nzira dzedziviriro dzechirimwa kurwisa chirwere ichi. Kana yakafumurwa kuBCP, chirimwa chinoburitsa mazinga epamusoro ekudzivirira makomisheni anogona kubatsira kurwisa fungus. Kuwanikwa uku kunogona kuve nemhedzisiro yakakosha kuvarimi, sezvo ichipa nzira nyowani yekudzivirira zvirimwa zvavo pasina kuvimba nemishonga inodhura uye inogona kukuvadza makemikari.
Nepo tsvagiridzo ichiri mumatanho ekutanga, pane chikonzero chekuve netarisiro pamusoro pezvakanakira kuwanikwa uku. Pamusoro pekugona kwayo kuchengetedza mbesa dzembatatisi nematomatisi kubva kunonoka blight, BCP inogona zvakare kuve nekushandiswa mune dzimwe nzvimbo dzekurima, sekudzivirira zvimwe zvirimwa kubva kune zvipembenene nezvirwere.
Kuwanikwa kwemabhenefiti angangove eBCP mukudzivirira mbesa dzembatatisi nematomatisi kubva kunonoka blight ibudiriro inonakidza mukurima. Nepo kumwe kutsvagurudza kuchidikanwa kuti unzwisise zvizere kushanda kwayo uye mashandisirwo angangoita, kuwanikwa uku kunopa chishandiso chitsva chevarimi kuchengetedza zvirimwa zvavo uye kuderedza kuvimba kwavo nemishonga yemakemikari.
