Low manganese status affects younger leaves and active growing points. Plants display slow growth, lax canopy and low vigour. Young leaves show a distinct mottled interveinal chlorosis.
Manganese deficiency restricts the conversion of sunlight to plant energy, resulting in slow growth rates, poor development and low tolerance to both biotic and abiotic stress. Low manganese status is often associated with alkaline soils and cold, wet growing conditions.
Check soil status and root development for compaction. Seed treatment and routine foliar treatment can be very effective, especially during the early stages of plant development and times of stress.
