Kutunza Shamba

Sehemu hii tutazungumzia jinsi ya kutunza shamba la mahindi ambapo tutagusia mambo makuu manne (4) ambayo ni; nyasi na magugu shambani, mbolea, wadudu shambani, pamoja na matumizi ya kemikali shambani. Mambo haya manne yamefafanuliwa zaidi hapa chini.

Eyespot

Wadudu: Fangasi: Aureobasidium zeae

Dalili: 1. Vialama kadhaa vyenye muundo wa mduara au kama yai, kipenyo cha sm 0.5, katikati ya hizo alama pana rangi ya tan mpaka ya krimu, pembezoni kuna rangi ya kahawia mpaka ya zambarau na kuzungukwa na halo ya kimanjano kwenye majani 2. Majani ya juu yanaweza kukauka na kufa mapema

Suluhisho/ Kutibu: 1. Panda mbegu za mahindi zenye kuweza kukabiliana na hili tatizo 2. Kulima vizuri na kilimo mzunguko hupunguza ukubwa wa tatizo 3. Pulizia kemikali za kumaliza fangasi kwenye majani kama Vanguard, Unix, Amistar, Bravo and Score
