Ukusasazeka kunye nomonakalo we-Curvularia leaf blight
Ngenxa yokungakhathali kubaphathi kunye nezinye izizathu, ingca ikhula kwindawo eyomileyo nembi kwaye isengozini yezifo.ukusuleleka kwengcaKwintsapho encinci yeArtemisia, iCurvularia iyakosulela ingca yentsapho encinci yePooideae, efana ne-bluegrass, i-meadow bluegrass, i-fine-leaved fescue, i-Canada bluegrass, i-ryegrass, njl.njl.
Ingozi: Ingca enesifo ibuthathaka, incinci, kwaye inamabala angaqhelekanga engceni afileyo. Iikholamu zengca ngaphakathi kwamabala afileyo zincinci kwaye zimfutshane, kwaye zibonakala zingwevu kwaye zifile. Amagqabi anesifo engca eluhlaza okwesibhakabhaka kunye ne-fescue enamagqabi amancinci atshintsha ukusuka kumthubi ukuya kumdaka ukusuka encamini ukuya kwisiseko, aze abe ngwevu, de lonke igqabi life. Iintlobo ezahlukeneyo zezifo zibangela iimpawu ezahlukeneyo. Umzekelo, xa i-Curvularia crescentus ihlasela ingca eluhlaza okwesibhakabhaka, izilonda kumagqabi anesifo ziyi-oval okanye i-fusiform, umbindi wezilonda zingwevu, indawo ejikelezileyo imdaka, kwaye kukho ii-halos ezimthubi ngaphandle. Xa amagqabi egqunywe zizilonda, ayafa.
Iimeko zeCurvularia blight blight
Ubushushu: Kulula ukwenzeka xa ubushushu obuphezulu bufikelela kuma-30 degrees kwindawo enomswakama ophezulu.
Izinto ezibangela usulelo: Ingca ejongene nobunzima obuphezulu okanye ukuyeka ukukhula ngenxa yobushushu obuphezulu. Ingca, izityalo ezahlukeneyo zokutya okuziinkozo, kunye nokhula lwengca. Ingca ekhuliswe kakubi, engaphathwanga kakuhle, kwaye engakhuliswanga kakuhle. Inokwenzeka kwiindawo ezifumileyo kunye nezichumisi ze-nitrogen eninzi.
Indlela yokudlulisela: Ukusasazwa ngumoya nemvula.
Ukuthintela nonyango lwe-Curvularia leaf blight
Imbewu: Khetha imbewu ekwaziyo ukumelana nezifo kwaye engenazo izifo, uze udibanise iintlobo ezahlukeneyo zembewu yengca.
Ukutyala kunye nokuchumisa: Gquma umhlaba ngokufanelekileyo xa uhlwayela, qwalasela ulawulo lwezithole, faka isichumisi se-nitrogen ngokufanelekileyo, kuphephe ukusetyenziswa kakhulu ekuqaleni kwentwasahlobo naphakathi kwehlobo, kwaye wandise isichumisi se-phosphorus kunye ne-potassium.
Ukunkcenkceshela: Ukunkcenkceshela kufuneka kwenziwe kusasa, kuthintelwe ukunkcenkceshela ngokuhlwa, kuncenceshelwe nzulu nangokucokisekileyo, kuncitshiswe ukunkcenkceshela rhoqo, kwaye kuthintelwe ukuqokelelwa kwamanzi engceni.
Ukucheba: Nika ingqalelo kubude bokucheba, ubuncinane yi-5 ukuya kwi-6 cm.
Indawo engqongileyo: Susa amagqabi aseleyo engceni enesifo nefileyo ngexesha emva kokuthena, kwaye ucoce umaleko wengca efileyo rhoqo.
Amanyathelo okunyanga isifo samagqabi eCurvularia
