OPTIMAN FOLIAR MANGANESE
OptiMan – High-Availability Foliar Manganese for Arable & Field Vegetable Crops
OptiMan Foliar Manganese Use:
OptiMan is a high-efficiency foliar manganese fertiliser designed to provide essential micronutrient support for arable and field vegetable crops.
It has been developed as an all-round, high-availability source of manganese for foliar application, helping introduce key nutrients from the early stages of foliar growth and crop development. OptiMan is particularly useful where manganese uptake from the soil may be limited by dry conditions, soil type, pH or periods of rapid crop demand.
Key benefit:
Delivers precise foliar manganese nutrition when soil uptake is limited
OptiMan helps make manganese nutrition less dependent on unfavourable soil or weather conditions. Foliar application allows accurate timing, even coverage and direct uptake during key crop growth stages, especially when soils are dry or manganese availability is restricted.
Benefits:
- Provides a high-availability source of foliar manganese.
- Supports essential micronutrient nutrition in arable and field vegetable crops.
- Helps maintain crop growth and development where manganese availability is limited.
- Allows precise application timing during periods of crop demand.
- Supports even foliar application and uptake.
- Helps reduce reliance on soil manganese availability during dry conditions.
- Contains sulphur and magnesium alongside manganese.
- Suitable for use from around the 3-leaf stage onwards where sufficient leaf area is present.
When and where to use:
OptiMan should be applied as a foliar spray when the crop has enough leaf area to absorb the spray. This normally coincides with the 3-leaf stage onwards in most crops.
For best nutrient uptake, apply in the early morning or late evening, when plant uptake conditions are more favourable. Timing should be based on crop, growth stage, manganese requirement and agronomic advice.
Crops:
All arable and field vegetable crops.
Pack Size:
20 L, 1000 L (IBC)
Technical Information – OptiMan
OptiMan is a liquid foliar fertiliser containing manganese, sulphur and magnesium. It is formulated as a high-availability source of manganese to support crop growth and micronutrient nutrition during early foliar development and periods of high demand.
As nutrients are taken up through the foliage, sufficient leaf area must be present before application. In most crops, this usually means applying from the 3-leaf stage onwards.
| Analysis | w/v % | g/L |
| Sulphur (SO3) | 22.53 | 225.3 |
| Manganese (Mn) | 14.71 | 147.1 |
| Magnesium (MgO) | 0.39 | 3.90 |
Application – OptiMan
- Apply as a foliar spray only when sufficient leaf area is present.
- In most crops, this usually coincides with the 3-leaf stage onwards.
- Apply in the early morning or late evening for best uptake.
- Do not spray when crops are stressed by very hot weather or drought.
- Shake the container well before opening and use.
- Ensure spray equipment is clean before adding product.
- Half-fill the spray tank with water.
- Begin agitation and add the required quantity of OptiMan to the tank.
- Rinse the container thoroughly and add the rinsings to the sprayer.
- Continue agitation until spraying is complete.
- Spray without delay once mixed.
- Do not leave products in the tank for long periods.
- When used alongside pesticides, mix OptiMan into the tank last.

Frequently Asked Questions – OptiMan
1. What is OptiMan used for?
OptiMan is used as a foliar manganese fertiliser for arable and field vegetable crops. It provides high-availability manganese to support micronutrient nutrition, crop growth and development, especially where soil uptake may be restricted.
2. When should OptiMan be applied?
OptiMan should be applied when there is enough leaf area to absorb the spray, normally from the 3-leaf stage onwards in most crops. Applications are best made in the early morning or late evening.
3. What rate of OptiMan should be used?
The recommended rate is 1.0–3.0 L/ha in 100–200 L water/ha, depending on crop, growth stage and manganese requirement.
4. Can OptiMan be tank-mixed with pesticides?
OptiMan is compatible with a wide range of agrochemical products, but a jar test should be carried out before adding it to a new tank mix. When used alongside pesticides, OptiMan should be mixed into the tank last.
