Banana bunchy top virus () banana bunchy top virus

"The initial symptom [of banana bunchy top virus] is the presence of dark-green spots on the petioles, midribs, and leaf veins of the newly emerging leaves. The infected leaves [of the banana plant] are erect, narrow, stunted, and often have yellow leaf margins. The leaves become smaller as the disease progresses. Eventually, the crown of the plant is composed of only stunted leaves, producing a 'bunchy top,' hence the name. The infected plant does not produce any fruit or the bunch does not emerge from the pseudostem." (PAN Germany, accessed 10 May 2008)
