YaraAmplix Flostrel 5L– Seaweed Biostimulant with Phosphorus & Boron for Flowering and Fruit Set
Specifications
Details
YaraAmplix FLOSTREL 5L
Targeted flowering support before and during bloom. A concentrated formulation combining Ascophyllum nodosum seaweed extract with phosphorus and boron to support flower development, pollen performance and flower retention.

Designed for the Critical Flowering Window
FLOSTREL is not just a general seaweed product. Its high-phosphorus, high-boron formulation is designed for focused use from pre-flowering to the early flowering stage.

Supports Flower Development
Phosphorus supports energy transfer and the high metabolic demand associated with reproductive growth.
Supports Pollination
Boron plays an important role in pollen germination, pollen-tube growth, fertilisation and the formation of new tissues.
Helps Plants Through Flowering Stress
Ascophyllum nodosum-derived bioactive compounds support plant physiological activity during a weather-sensitive growth stage.
Key Composition
Concentrated nutrition combined with an Ascophyllum nodosum seaweed-extract base.
Why Seaweed + Phosphorus + Boron?
(1).png)
Ascophyllum nodosum
A brown seaweed containing naturally occurring compounds such as alginates, mannitol, betaines, fucoidan and polyphenols. These compounds are associated with plant growth responses and tolerance to abiotic stress.
Phosphorus (P)
Supports energy transfer, root activity and the metabolic processes required for flower initiation and reproductive development.
Boron (B)
Supports pollen viability, pollen-tube elongation, fertilisation, cell-wall formation and the retention of flowers and young fruit.
Recommended Application
Apply within the targeted flowering window. Always follow the registered Malaysian product label and the crop-specific recommendation provided by your agronomist.

| Crop Group | Application Rate | Recommended Timing |
|---|---|---|
| Fruit Crops | 1–2 L/ha | One application before flowering and one during flowering; 2 applications in total. |
| Field Crops | 1 L/ha | Before flowering and during flowering; 1–2 applications. |
FLOSTREL or OPTITRAC?
Both products support reproductive growth, but they are designed for different application windows.

| Comparison | YaraAmplix FLOSTREL | YaraAmplix OPTITRAC |
|---|---|---|
| Main timing | Pre-flowering to early flowering | Flowering, fruit set and early fruit development |
| Main objective | Flower preparation, flower development and retention | Fruit-set support and early fruit development |
| Nutrition profile | High P + high B | N + K + Zn + B |
| Best suited when | Flower initiation is weak, flowering is uneven or flower retention needs support | Flowering is established but fruit set and young-fruit development need continued support |
Programme approach: FLOSTREL may be used before flowering, followed by OPTITRAC from flowering into fruit set, subject to crop needs and the approved label directions.
Trial Direction

Tomato Trial
Under the stated trial conditions, applications beginning at first flower and repeated at 7–10-day intervals produced 20% more fruit and 33% greater total fruit weight than the untreated control.
Strawberry Trial
FLOSTREL delivered stronger fruit-number and fresh-weight results than a comparable phosphorus-and-boron treatment alone, indicating a potential contribution from the seaweed-based biostimulant system.
Trial results are specific to the crop, site, programme and conditions tested. They are presented as technical evidence of product direction and are not a guarantee of identical results in every farm.
