Munyika yezvekurima, utachiona hwezvirimwa hunogona kukanganisa goho, zvichikonzera kurasikirwa kukuru kwehupfumi kuvarimi nevaridzi vemapurazi. Humwe hutachiona hwakadai huchangobva kutariswa iTomato Ringspot Virus (ToRSV). Chinyorwa ichi chichaongorora ichangoburwa data paToRSV, kusimukira kwayo, mhedzisiro, uye nzira dzekudzikisa kukanganisa kwayo pakugadzirwa kwezvirimwa.
Tomato Ringspot Virus (ToRSV) utachiona hwechirimwa hunobata zvirimwa zvakasiyana siyana, kusanganisira matomatisi, muzambiringa, apuro, uye peach. Zvinoenderana neazvino data kubva kuUnited States Dhipatimendi Rezvekurima (USDA), ToRSV yakapararira mumatunhu akati wandei, ine chiitiko chepamusoro chakataurwa muWashington, Oregon, neIdaho.
Utachiona hweToRSV hunogona kukonzera zviratidzo zvakasiyana-siyana, zvinosanganisira kumira, kutsvuka, uye necrosis yemashizha, uye zvipembenene zvemhete pamichero, zvinozopedzisira zvaita kuti kuderedzwa kwegoho uye kunaka.
Kubudirira kweToRSV kunonyanya kuburikidza nematodes, ayo anotakurwa nevhu uye anogona kutapurira hutachiona kubva kune hutachiona kuenda kune hutano zvirimwa. Kana hutachiona hwangopinda muchirimwa, hunodzokorora nekukurumidza uye hunopararira muchirimwa chose, zvichiita kuti zviome kudzora.
Mhedzisiro yehutachiona hweToRSV inogona kuve yakaoma, inokanganisa kugona kwehupfumi hwemabasa ekurima. Ongororo yakaitwa neUSDA inofungidzira kuti utachiona hweToRSV hunogona kukonzera kurasikirwa kwegoho kusvika pa30% muminda yemaapuro nemapichisi, zvichikonzera kurasikirwa kwemari inosvika madhora makumi manomwe ezviuru pahekita.
Kudzikamisa kukanganiswa kweToRSV, varimi nenyanzvi dzezvekurima vanofanirwa kuita nhanho dzekudzivirira dzakaita sekuchinjanisa zvirimwa, kupfutisa ivhu, uye kushandiswa kwezvinhu zvakasimbiswa zvekudyara zvisina chirwere. Pamusoro pezvo, kushandiswa kwemidzi inodzivirira nematode kunogona kuderedza kuitika kwekubatwa nematode uye kutapurirana kweToRSV kunotevera.
Mukupedzisa, ToRSV inotyisa yakavanzika kune goho rezvirimwa uye inogona kukonzera kurasikirwa kukuru kwehupfumi kuvarimi nevaridzi vemapurazi. Matanho ekudzivirira, akadai sekutenderedzwa kwezvirimwa, kupfutidza ivhu, uye kushandiswa kwemidzi inodzivirira nematode, zvinogona kubatsira kudzikisira kukanganiswa kweToRSV pakugadzirwa kwezvirimwa.
