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.

Physoderma Brown Spot

Wadudu: Fangasi: Physoderma maydis

Dalili: 1. Alama/ vidonda huanza kwa kuweka vialama vidogo vya njano ambapo baadae hubadilika na kuwa na rangi ya zambarau iliyokolea mpaka nyeusi, umbo linakuwa kama la yai na hizi alama hutokea katikati ya majani 2. Zambarau iliyokolea, alama za mviringo huweza kutokea pia kwenye mabua na sehemu zingine

Suluhisho/ Kutibu: 1. Panda mbegu za mahindi zenye kuweza kukabiliana na hili tatizo 2. Weka dawa za kupambana na fangasi wa kwenye majani kama vile Folicur, Ridomil Gold, Bravo and Score kipindi ambacho alama/ vidonda vya mwanzo vinaanza.
