Ikwirakwizwa n'ingaruka za Curvularia leaf blight
Bitewe n'uburangare bw'ubuyobozi n'izindi mpamvu, ubwatsi bukurira ahantu habi kandi hakomeretse kandi bukunze kwibasirwa n'indwara. Uretsekwanduza ibyatsiMu muryango muto wa Artemisia, Curvularia izandura ibyatsi byo mu muryango muto wa Pooideae, nka bluegrass, meadow bluegrass, fine-leaved fescue, Canada bluegrass, ryegrass, nibindi.

Ingaruka: Ubusitani burwaye burakomeye, buranutse, kandi bufite ubwatsi bupfuye butari bumwe. Inkingi z'ubwatsi ziri imbere mu bwatsi bupfuye ziba zoroshye kandi ngufi, kandi zisa n'umukara kandi zapfuye. Amababi arwaye ya fescue y'ubururu bw'inka n'amababi meza ahinduka umuhondo akava ku ibara ry'umukara kuva ku mutwe kugeza ku gice cyo hasi, hanyuma akaba umukara, kugeza igihe ikibabi cyose gipfuye. Ubwoko butandukanye bw'udukoko dutera indwara butera ibimenyetso bitandukanye. Urugero, iyo Curvularia crescentus yanduje ubwatsi bw'inka, ibikomere ku mababi arwaye biba ari nk'urudodo cyangwa fusiform, hagati y'ibikomere biba ari umukara, ibidukikije biba ari umukara, kandi hari imiterere y'umuhondo inyuma. Iyo amababi yuzuye ibikomere, arapfa.

Ubushyuhe: Biroroshye kubaho iyo ubushyuhe bwinshi bugeze kuri dogere 30 mu kirere gifite ubushuhe bwinshi.

Ibikoresho byandura: Kwanduza ibyatsi birimo guhura n’ikibazo cy’ubushyuhe bwinshi cyangwa bigahagarara bitewe n’ubushyuhe bwinshi. Ibyatsi, ibinyampeke bitandukanye, n’ibyatsi bibi. Ibyatsi bibi, bitagengwa neza, kandi bikuze nabi. Bishobora kubaho ahantu hashushe kandi hafumbire mvaruganda nyinshi ya azote.

Uburyo bwo kwanduzanya: Gukwirakwira n'umuyaga n'imvura.

Imbuto: Hitamo imbuto zifite ubwatsi burwanya indwara kandi butagira indwara, kandi uvange ubwoko butandukanye bw'imbuto z'ubwatsi.

Kubiba no gufumbira: Gupfuka ubutaka neza mu gihe utera, kwita ku micungire y'imbuto, gushyiramo ifumbire ya azote mu buryo bukwiye, kwirinda gukoresha ifumbire nyinshi mu ntangiriro z'impeshyi no hagati mu mpeshyi, kandi wongere ifumbire ya fosifore na potasiyumu.

Kuhira: Kuhira bigomba gukorwa mu gitondo, kwirinda kuhira nimugoroba, kuhira cyane kandi neza, kugabanya kuhira kenshi, no kwirinda kwirundanya kw'amazi mu busitani.

Gukata: Witondere uburebure bw'aho gutema, nibura ni cm 5 kugeza kuri 6.

Ibidukikije: Kuraho amababi yasigaye y'ibyatsi birwaye n'ibyapfuye nyuma yo gutema, kandi usukure urwego rw'ibyatsi byapfuye kenshi.
