Beans Physiological Disorders
ToT to FFS Staff By Mr. Allah Dad Khan
Provincial Coordinator IPM KPK MINFAL
Symptoms
Stems thin, leaves erect; early defoliation of basal leaves
Broad Bean Plants Phosphorus deficiency
Symptoms
Young growth deformed, young stems and petioles wilt and growing points die; leaflets near growing points fail to expand, distorted and hooked, and tips die.
Broad Bean Plants Calcium deficiency
Symptoms
Pods deformed, wilted and blackened; seeds fail to develop.
Broad Bean Pods and Seeds Calcium deficiency
Symptoms
Internodes short; leaves dark brown marginal scorch and margins curled forward
Broad Bean Shoot Potassium deficiency
Symptoms
Brown lesions in centers of cotyledons, similar "Marsh Spot" in peas
Broad Bean Seeds Manganese deficiency
Symptoms
Stems somewhat stiff; growing points die and lateral growths develop from bases of shoots; leaves slight intervenal chlorosis
Broad Bean Plants Boron deficiency
Symptoms
Growth dwarfed and thin; leaves pale green and older leaves yellow and die early
Dwarf (French) Bean Plants Nitrogen deficiency
Symptoms
Growth dwarfed and thin: leaves dark, lustrelessgreen, older leaves turn brown and shed early
Dwarf Bean Plants Phosphorus deficiency
Growth dwarfed and thin; stems, petioles, pedicels and pods wilted; early defoliation.
Dwarf Bean Plants Calcium deficiency
Symptoms
Older leaves chlorotic mottling, followed by general yellowing and brown necrotic spotting.
Dwarf Bean Foliage Magnesium deficiency
Symptoms
Stems abnormally thickened; longitudinal splitting of epicotyl; death of growing point; leaves some chlorosis.
Dwarf Bean Plants Boron deficiency
Symptoms
Brown lesions in cotyledons, similar "Marsh Spot" of peas
Haricot Bean Seeds Manganese deficiency
Symptoms
Growth stunted and thin; leaves pale green and older leaves yellow and die early; stems and petioles tend to be tinted red
Runner Bean Plant Nitrogen deficiency
Symptoms
Leaves pale green, tips and margins of leaflets chlorotic patches and brown spots
Runner Bean Leaves Calcium deficiency
Symptoms
Leaflets slightly pale and striking intervenal necrosis
Runner Bean Leaf Magnesium deficiency
Symptoms
Leaflets curled backward; intervenal chlorosis and brown marginal scorch; scorched margins curled forward.
Runner Bean Foliage Potassium deficiency
Sym[ptoms
Brown lesions in cotyledons, similar to "Marsh Spot" of peas.
Runner Bean Seeds Manganese deficiency
Symptoms
Leaves intervenalchlorosis beginning at margins, followed by brown necrotic spotting
Runner Bean Plant Manganese toxicity (soil acidity complex)
Symptoms
Intervenal chlorosis and fine necrotic brown spotting.
Runner Bean Leaves Manganese toxicity (soil acidity complex
Symptoms
Stem thickened and stiff; growing points die; leaves slight chlorotic mottling
Runner Bean Stem and Leaves Boron deficiency
