1.RESEARCH ON LEAF SCORCH OF NARCISSUS——OCCURRENCE, DAMAGE,SYMPTOMS AND CAUSAL AGENT
2.RELATIONSHIP BETWEEN THE BANANA MARGINAL SCORCH AND THE FLUORIDE CONTENT OF THE BANANA LEAF
3.Foliage is dark green, leaflets of older leaves have convex curvature; profuse, almost black necrotic speckling between veins (often appearing first on under surfaces) coalesces into larger marginal and intervernal areas with occasional slight marginal chlorosis, followed by total scorch and leaf collapse.
