ACTIVATOR ORGANIC ACIDS & BIOSTIMULANT
Activator – Organic Acids & Biostimulants for Nutrient Uptake & Crop Vigour
Activator Organic Acids & Biostimulants Use:
Activator is a liquid biostimulant and nutrient uptake enhancer designed to stimulate crop growth and improve the translocation of nutrients within target crop plants.
It is based on natural organic acid chelating agents and organic complexes, providing an effective delivery mechanism for nutrients to growing points in the plant. Activator is designed for use with the OptiYield range of foliar nutrition products and can help improve crop vigour, nutrient efficiency, yield and quality
Key benefit:
Improves nutrient movement, uptake and crop vigour
Activator helps condition spray water and supports the movement of nutrients to areas of active growth within the plant. Its organic acid and biostimulant complex helps improve the effectiveness of foliar nutrition programmes, supporting crop vigour regardless of immediate nutrient demand.
Benefits:
- Stimulates crop growth and nutrient translocation.
- Helps deliver nutrients to growing points within the plant.
- Supports improved crop vigour.
- Helps improve yield and quality as part of a foliar nutrition programme.
- Based on natural organic acid chelating agents.
- Contains active biostimulants that support plant performance.
- Designed for use with the OptiYield foliar nutrition range.
- Helps condition spray water for improved spraying efficiency.
- Suitable for use across a wide range of arable, field vegetable and horticultural crops.
When and where to use:
Activator should be used alongside OptiYield foliar nutrition products where improved nutrient uptake, movement and crop response are required.
Timing depends on the crop, growth stage and companion product being used. Activator is suitable for foliar application as part of a nutrient recommendation programme.
Crops:
A wide range of arable, field vegetable and horticultural crops.
Pack Size:
10 L
Technical Information – Activator
Activator is based on natural organic acid chelating agents and organic complexes. These compounds provide a highly effective delivery mechanism for nutrients to growing points in crops, while also acting as biostimulants that support crop vigour independently of nutrient demand.
Activator is designed for use with OptiYield foliar nutrition products and should be added to the spray tank last to help ensure the water is suitably conditioned for maximum spraying efficiency.
