Manganese Plus™

Manganese Plus is a formulation of manganese and iron chelated with citric acid to improve availability and enhance uptake. 

Manganese is involved in the synthesis of chlorophyll, in oxidation-reduction reactions, and as a cofactor in various enzyme systems. The function of manganese is closely related to iron in plants. 

Manganese Plus is designed for foliar application to correct and prevent manganese deficiencies in turfgrasses and ornamental plants. It may also be used to reduce the severity of take-all patch in bentgrass.

• Manganese deficiency in alkaline or highly leached sandy soils
• Manganese deficiency symptoms including chlorosis
• Take-all patch in newly established bentgrass

Manganese Plus can be applied through fertigation, soil drench, conventional or foliar
spray. It can be applied alone or tank mixed with other products.✝ Shake well before
using.

Turf:
Apply 3 oz. of Manganese Plus diluted in 1 gallon of water per 1,000 sq. ft. (1 gallon in
40 gallons of water per acre) every two weeks or as needed. To maximize performance, the rates may be split into weekly applications.

Evergreens, Deciduous Shrubs, Trees and Palms:
Foliar Application: Mix 1 to 2 gallons of Manganese Plus in 100 gallons of water and
spray foliage to the point of runoff. Best results will occur when applied to actively
growing foliage during periods of high humidity and low plant stress (early mornings,
late afternoons and cloudy days are preferable to hot, dry conditions).

Soil Drench: Mix 4 to 5 gallons of Manganese Plus in 100 gallons of water and drench
around the base of each plant within the dripline. Approximately 1 to 2 gallons of finished solution will be adequate for most ornamentals.

Take-all Patch Suppression:
University studies show that an application of 2 lbs. of Mn per acre in the spring or
fall will suppress take-all patch by as much as 70%. To achieve this rate apply 12 oz. of
Manganese Plus in 2 gallons of water per 1,000 sq. ft. (4 gallons of Manganese Plus in 80
gallons of water per acre). Water into the root zone following the application.

✝ Compatibility: perform a standard jar test to check compatibility with other products before mixing.
