Panama disease characterize Panama disease of banana: These symptoms often get confused with the symptoms of bacterial wilt of banana, but ways to differentiate between the two diseases include: Once a banana plant is infected, it continues to grow and any new leaves will be pale in color. Recovery is rare, but if it does occur, any new emerging suckers will already be infected and can propagate disease if planted. "Fusarium oxysporum" f. sp. "cubense" (Foc) is most prominent in banana, but some other relatives are also susceptible to infection. Different races of the disease are used to classify different major hosts
Crop residue above-ground plant in the first year. There is some residual benefit of fertilizers as the crops take up a small amount of the nutrients two and three years later. Fertilizer placement can significantly affect the efficiency of crop uptake. The impact of residue placement (buried by tillage or left on the surface in zero tillage) on nutrient cycling and efficiency is under study. Thus, the practice of calculating the fertilizer equivalent value of the nutrients in crop residue is a reasonable guide to estimating the partial value of crop residues. Crop residue There are two types of agricultural crop residues.
