PRISM FOLIAR MICRONUTRIENT & BIOSTIMULANT
Prism – Foliar (Mn, Zn, Cu, S) Micronutrient & Biostimulant
Prism Foliar Micronutrient and Biostimulant Use:
Prism is a combined foliar micronutrient and biostimulant product containing manganese, zinc, copper and sulphur, supported by humic and fulvic acids.
It is designed to support crop growth, nutrient balance and micronutrient availability, particularly where crops require maintenance nutrition or correction of manganese, zinc or copper deficiency. Prism is suitable for foliar application across arable and field vegetable crops and can help maintain performance during key growth stages.
Key benefits:
Provides broad micronutrient support in one foliar application
Prism delivers a targeted combination of manganese, sulphur, zinc and copper to support healthy crop growth, nutrient efficiency and crop resilience. Its advanced foliar formulation is designed for fast uptake through the leaf, helping crops access key micronutrients quickly when demand is high.
Benefits:
- Provides manganese, zinc and copper in one foliar formulation.
- Includes sulphur to support crop nutrition and nutrient balance.
- Contains humic and fulvic acids with biostimulant activity.
- Helps support crop growth and yield potential.
- Useful for maintenance micronutrient applications.
- Can be used where marginal, moderate or severe micronutrient deficiencies are present.
- Supports precise foliar nutrition during periods of crop demand.
- Helps reduce reliance on soil micronutrient availability during dry or limiting conditions.
- Suitable for arable and field vegetable crops.
When and where to use:
Prism should be applied as a foliar spray when there is sufficient leaf area for good uptake. It can be used for maintenance applications or where manganese, zinc or copper deficiency has been identified through crop symptoms, tissue analysis or agronomic recommendation.
For best nutrient uptake, apply in the early morning or evening. Avoid spraying when crops are stressed by very hot weather or drought.
Crops:
All arable and field vegetable crops.
Pack Size:
10 L, 1000 L (IBC)
Technical Information – Prism
Prism is a liquid foliar micronutrient and biostimulant formulation containing manganese, sulphur, zinc, copper and humic and fulvic acids. The combination is designed to provide broad trace element support in a single foliar application.
Manganese supports photosynthesis and crop metabolism, zinc supports enzyme activity and growth regulation, and copper contributes to plant health and physiological function. Humic and fulvic acids support nutrient mobility and formulation performance.

Application – Prism
General application guidance
- Apply as a foliar spray when sufficient leaf area is present.
- Use sufficient water to ensure good coverage.
- For best nutrient uptake, apply in the early morning or evening.
- Do not spray when the crop is stressed by very hot weather or drought.
- Shake the container well before opening and use.
- Three-quarter fill the spray tank with water.
- Add Prism slowly to the tank while agitating.
- Top up with water and spray.
- Continue agitation during mixing and spraying.
- Spray without delay once mixed.
- Do not leave products in the tank for long periods.
| Crop / Situation | Timing | Rate |
|---|---|---|
| Maintenance micronutrient applications | Apply when there is sufficient foliage and crop demand | 1.0 L/ha |
| Marginal to moderate deficiency | Apply when deficiency is identified or expected | 2.5 L/ha |
| Moderate to severe deficiency | Apply when deficiency pressure is higher | 3.5 L/ha |
| Foliar application water rate | Use sufficient water for good coverage | Minimum 150 L water/ha |
COMPATIBILITY
- Prism is compatible with a wide range of agrochemical products, but compatibility should be checked before use.
- Carry out a jar test before adding to a new tank mix.

Frequently Asked Questions – Prism
1. What is Prism used for?
Prism is used as a foliar micronutrient and biostimulant product to provide manganese, zinc, copper and sulphur, with humic and fulvic acids, for broad crop nutrient support.
2. Which deficiencies can Prism help address?
Prism can be used where manganese, zinc or copper deficiency is identified or expected. The label provides rates for maintenance use, marginal to moderate deficiency, and moderate to severe deficiency.
3. What rate of Prism should be used?
Use 1.0 L/ha for maintenance applications, 2.5 L/ha for marginal to moderate deficiency, and 3.5 L/ha for moderate to severe deficiency. Apply in no less than 150 L water/ha.
4. Can Prism be tank-mixed with other products?
Prism 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. Consult your distributor, agronomist or Emerald Research representative for specific compatibility advice.
