OPTIBOR FOLIAR BORON FERTILISER
OptiBor – Foliar Boron Fertiliser for Arable Crops
OptiBor Foliar Boron Use:
OptiBor is a high-availability foliar boron fertiliser developed to supplement this essential micronutrient from the early stages of foliar growth and crop development.
Boron supports key plant processes linked to cell wall development, growing points, flowering, pollination, fruit and seed set. OptiBor is designed for use across arable and field vegetable crops where boron demand is high, soil availability is limited, or a foliar boron application is required as part of a crop nutrition programme. Emerald Research lists OptiBor as a foliar nutrient and describes it as a high-availability source of boron for foliar application.
Key benefit:
Supports growing points, flowering and crop development
OptiBor delivers a concentrated source of foliar boron, helping support healthy growing points, reproductive development and crop quality during key growth stages. Foliar application allows boron to be applied accurately when the crop has sufficient leaf area and demand is increasing.
Benefits:
- Provides a high-availability source of foliar boron.
- Supports growing points and new tissue development.
- Helps support flowering, pollination and seed or fruit set.
- Useful where boron availability from the soil is limited.
- Suitable from the early stages of foliar growth and crop development.
- Supports crop quality and reproductive performance.
- Suitable for all arable and field vegetable crops.
- Particularly relevant for boron-responsive crops such as oilseed rape, brassicas, beet and field vegetables.
When and where to use:
OptiBor should be applied as a foliar spray when there is sufficient leaf area to absorb the spray. It is suitable from the early stages of foliar growth and crop development.
For best nutrient uptake, apply in the early morning or evening. Avoid spraying when crops are stressed by very hot weather or drought. Timing should be based on crop, growth stage, boron requirement and agronomic advice.
Crops:
All arable and field vegetable crops, including oilseed rape, brassicas, beet, potatoes and other crops where boron is required.
Pack Size:
10 L, 1000 L (IBC)
Technical Information – OptiBor
OptiBor is a liquid foliar fertiliser containing boron. It has been developed as a high-availability source of boron for foliar application, helping supplement crop boron requirements during early growth and key development stages.
Boron is an essential micronutrient associated with cell wall formation, growing point activity and reproductive development. Foliar application helps place boron directly onto the leaf when crop demand and leaf area are suitable.

Application – OptiBor
General application guidance
- Apply as a foliar spray when sufficient leaf area is present.
- Use from the early stages of foliar growth and crop development.
- Apply in the early morning or evening for best nutrient 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 OptiBor 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 OptiBor into the tank last.

Frequently Asked Questions – OptiBor
1. What is OptiBor used for?
OptiBor is used as a foliar boron fertiliser to supplement crop boron requirements from the early stages of foliar growth and crop development. It supports growing points, cell wall development, flowering, pollination and seed or fruit set.
2. Which crops can OptiBor be used on?
OptiBor is suitable for all arable and field vegetable crops. It is especially relevant for boron-responsive crops such as oilseed rape, brassicas, beet and field vegetables.
3. What rate of OptiBor should be used?
The recommended label rate is 1.0–3.0 L/ha in 100–200 L water/ha, applied when there is sufficient crop leaf area for foliar uptake.
4. Can OptiBor be tank-mixed with pesticides?
OptiBor 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, OptiBor should be mixed into the tank last.
