Ndakasarudza kuedza mishonga yefungicide pasoya kekutanga gore rino. Ndingaziva sei kuti ndoedza mushonga wefungicide upi, uye ndinofanira kuushandisa riini? Ndingaziva sei kana zvichibatsira?
Dare remazano ezvirimwa rakanyoreswa muIndiana rinopindura mubvunzo uyu rinosanganisira Betsy Bower, Ceres Solutions, Lafayette; Jamie Bultemeier, nyanzvi yezvekurima, A&L Great Lakes Lab, Fort Wayne; naAndy Like, murimi uye CCA, Vincennes.
Bower: Tarisa kusarudza mushonga wefungicide une nzira dzakasiyana dzekushanda dzinosanganisira triazole nestrobiluron. Zvimwe zvinosanganisirawo chinhu chitsva chinoshanda SDHI. Sarudza chimwe chine basa rakanaka pafrogeye leaf spot.
Kune nguva nhatu dzekudya soya dzinokurukurwa nevanhu vazhinji.Nguva imwe neimwe ine zvayakanakira nezvayakaipira.Dai ndiri mutsva pakushandisa mushonga wesoya, ndaizotarisa danho reR3, apo mapods achangotanga kuumbwa. Padanho iri, unowana kufukidzwa kwakanaka pamashizha mazhinji ari mudenga.
Kushandiswa kweR4 kwanonoka asi kunogona kushanda zvakanaka kana chirwere chedu chisina kukwira. Kune munhu anoshandisa mushonga wefungi kekutanga, ndinofunga kuti R2, inotumbuka zvizere, inguva pfupi yekuisa mushonga wefungi.
Nzira chete yekuziva kana mushonga wefungi uri kuwedzera goho ndeyekuisa mutsetse wekutarisa usina kuiswa mumunda. Usashandise mitsara yekupedzisira pamutsetse wako wekutarisa, uye iva nechokwadi chekuti upamhi hwemutsetse wekutarisa hunenge hukuru hwemusoro wekubatanidza kana musanganiswa wakatenderera.
Pakusarudza mishonga yefungi, tarisa pazvinhu zvinodzora zvirwere zvawakasangana nazvo mumakore apfuura paunenge uchiongorora minda yako usati watanga uye panguva yekuzadza zviyo. Kana ruzivo irworwo rusipo, tsvaga chigadzirwa chakasiyana-siyana chinopa nzira dzakasiyana dzekuita.
Bultemeier: Tsvagiridzo inoratidza kuti purofiti huru pakudyara mushonga wefungicide kamwe chete inobva pakushandiswa kweR2 kusvika pakutanga kweR3. Tanga kutsvaga minda yesoya kanenge vhiki rega rega kutanga painotumbuka. Tarisa pazvirwere nekumanikidzwa kwezvipembenene pamwe nedanho rekukura kuti uve nechokwadi chekuti mushonga wefungicide unoshanda kwenguva yakakwana. R3 inoonekwa kana paine pod ye 3/16-inch pane imwe yemapfundo mana epamusoro. Kana zvirwere zvakaita se white mold kana frogeye leaf spot zvikaonekwa, ungangoda kurapa usati wasvika R3. Kana mushonga ukaitika usati wasvika R3, mushonga wechipiri ungangodiwa gare gare panguva yekuzadzwa kwezviyo. Kana ukaona soya aphids, stinkbugs, bean leaf beetle kana Japanese beetle, kuwedzera mushonga wezvipembenene pakushandisa kunogona kukurudzirwa.
Iva nechokwadi chekusiya cheki isina kurapwa kuitira kuti yield ikwanise kuenzaniswa.
Ramba uchitarisa munda mushure mekushandisa, uchitarisa musiyano uripo pakati pehuwandu hwezvirwere pakati pezvikamu zvakarapwa nezvikamu zvisina kurapwa. Kuti mishonga inouraya zvipembenene iwedzere goho, panofanira kunge paine chirwere chiripo kuti mushonga unouraya zvipembenene udzore. Enzanisa goho riri parutivi nepakati pezvakarapwa nezvinorapwa munzvimbo dzinopfuura imwe chete mumunda.
Sekuti: Kazhinji, kushandisa fungicides panguva yekukura kweR3 kunopa mhedzisiro yakanaka kwazvo. Kuziva fungicide yakanakisa yekushandisa usati watanga chirwere kunogona kuoma. Muruzivo rwangu, fungicides ine nzira mbiri dzekuita uye yepamusoro pafrogeye leaf spot yakashanda zvakanaka. Sezvo iri gore rako rekutanga nefungicides yesoya, ndingasiya mitsetse mishomanana yekutarisa kana minda yakakamurwa kuti ndione mashandiro ezvigadzirwa.
