indwara n’ibyonnyi ku burayi

• Indwara n’ibyonnyi ndetse n’ibyatsi bibini bimwe mu bigabanya ku buryo bugaragara umusaruro w’ibirayi.
• Ni ngombwa kubirwanya kuko bishobora kugabanya umusaruro kugeza aho umuhinzi nta kintu na kimwe asarura.

Indwara zirimo amoko menshi, n'ibizitera biratandukanye. Muri byo twavuga indwara n'ibyonnyi bikurikira:

Indwara y’imvura

• Ikiyitera: indwara y’ imvura ni indwara iter­wa n’agahumyo .Ikunze kugaragazwa mu bihe by’imvura n’ubuhehere bwinshi.
• Aho ifata: amababi, uduti (imigozi) n’ikirayi
• Ibimenyetso: amababi n’uruti birababuka bigahinduka ikigina bikabora cyangwa bikuma.

Uburyo bwo kuyirwanya:

• Gutera amoko y’ ibirayi yihanganira iyo ndwara
• Ibirayi byose bigomba kuvanwa mu murima mu gihe cy’isarura
• Kurandura ibirayi byose byimejeje,
• Gusukira neza ibirayi ;

Mu bihe by’imvura nyinshi ndetse n’ubuhehere:

• Ibirayi bikimera, tera umuti nka Ridomili (Ridomil) ku mababi hose, gr 50 zivanze muri litilo 20 z’amazi ibirayi bikiri bitoya.               

Nyuma y’ibyumweru bibiri

• Rimwe mu cyumwer, Tera  umuti wa ditane cyangwa Mancozeb ku mababi hose ku rugero rwa gr 50 zivanze na litiro 20 z’amazi.
• Gusimburanya ibirayi n’ibindi bihingwa bitari mu muryango umwe.

 Indwara ya kirabiranya

• Ikiyitera :Kirabiranya y'ibirayi iterwa n’agakoko ko mu bwoko bwa bagiteri bita pseudomonas solanacearum. Iboneka mu butaka no mu mbuto byanduye ako gakoko.
• Aho ifata: ku mababi n'ibirayi.

Ibimenyetso:

• Kurabirana kw’amababi agahinduka icyatsi cyeruruka.
• Mu maso y’ibirayi birwaye cyane haturukamo amatembabuzi y’umweru wabitema ugasanga imbere hari uruziga rw’umuhondo.

Uburyo bwo kuyirwanya:

• Gukoresha amoko y’ imbuto y’ibirayi yihanganira iyo indwara,
• Gusimburanya ibirayi n’ibindi bihingwa bitari mu muryango umwe;
• Kurandura no kuvana mu murima ibirayi byose bigaragaraho ibimenyetso by’iyi ndwara;
• Gusimburanya ibihingwa  ku buryo ibirayi bigaruka nyuma y'ibihe bine by'ihinga.

Inanda

• Inanda iterwa n'agakoko ko mu bwoko bw'ibinyugunyugu bita “Phthorimaea operculella”;
• Udushorobwa twabyo ducukura imyobo mu mitsi y'amababi agahinduka ikigina;
• Utu tukoko twangiza ibirayi;
• Ibyo bigaragazwa n'imyobo ducukura mu kirayi n'amabyi yatwo agaragara mu kirayi;
• Ubwone bw'utu dukoko mu murima bushobora gukomereza no mu buhunikiro.

Uburyo bwo kuyirwanya:  

• Umuhinzi agirwa inama yo gutera indwara nzima itarwaye no gukoresha umuti witwa Deltamethrine cyangwa Cypemethrine mu rwego rwo kuyikumira.
