Asco Plus is a liquid seaweed based on Ascophyllum nodosum extract. Asco Plus supplements root and plant growth to improve general plant health, which may increase tolerance to heat and cold stress. Asco Plus is manufactured for fertigation or soil application and is suitable for use on all fruit, vegetable and ornamental crops to supplement existing nutrition and plant health programs.


The Ascophyllum nodosum used in Asco Plus grows in the Northern Atlantic Ocean where it is exposed to extremes in conditions from sub-zero temperatures to warm summer days; exposed to the sun at low tide and submerged at high tide. In this harsh environment, the seaweed has evolved many natural abilities to cope with extremes, so forms a valuable basis for our quality range. This Seaweed is farmed and harvested in a sustainable manner.

Campbells Asco Plus is suitable for use in vegetables, fruit, vines, flowers, turf and ornamentals.

Caution – Asco Plus is not certified for organic use (Conventional compounds utilised during the extraction and stabilisation of this product exclude it from consideration for organic registration, and given the volatile nature of many plant derived compounds, product stability is a high priority).


With the potential for wide-ranging plant responses to non-formulated biostimulants, Campbells Fertilisers Australasia recommends this product solely for fertigation. Campbells Asco Plus can be applied throughout the growth season via fertigation, at the end of an irrigation cycle, ensuring the product is properly washed into the root zone.


General rates for horticultural crops are between 2 – 8 L/ha in a single application, depending on the target crop (Refer product label). The actual rates, number of applications and their timing will vary considerably for different crops and for different districts.  Before application, seek advice from your Campbell’s distributor or your local agronomist.
