"Technical: Fe, Mn, Zn, Cu, B Target Crops: All the Field and Horticulture Crops Mode of Action: It can be absorbed my root and leaves." Micronutrients deficiency can be encountered by visual symptoms on crops and by testing soil and plant tissues. For understanding these visual symptoms, it is necessary to know the role each micronutrient plays in plant growth and development. Micronutrient Deficiency Symptoms: Except for Molybdenum, Other micronutrients are considered weakly mobile or immobile in plants. This means that deficiency symptoms appear severely on newest plant tissues, whereas for Molybdenum deficiency symptoms appear first on oldest plant tissues. Zinc deficiency results in stunted growth, lessened internode length, young leaves are smaller than normal. Iron deficiency leads to chlorosis or yellowing between the veins of new leaves. Boron deficiency results into light general chlorosis, a death of growing point, deformed leaves with areas of discoloration. Manganese (Mn) deficiency cause chlorotic mosaic patterns on leaves. Copper deficiency results in light overall chlorosis, leaf tips die back and tips are twisted, loss of turgor in young leaves.
