How we can help

At Biostart, we have created a biostimulant range that allows growers to achieve higher yields of nutrient-rich vegetables that store well through activating naturally occurring soil and plant microbes that are critical for nutrient uptake and crop health.

Our biostimulant products are compatible with nutritional and pest and disease control products so can be easily added into your current growing programme.

We have biostimulant programmes for a wide range of crops including: potatoes, brassicas, lettuce, pumpkin, squash, carrots, onions and kumara/sweet potatoes.

How to use our products

Standard vegetable programme

This programme can be used for a range of vegetables including greens, root crops, cucurbits, legumes, tomatoes, sweetcorn and potatoes.

Product Timing Application
Mycorrcin Seedling sowing Treat seedling trays with a 0.5 L/tray of a dilute Mycorrcin Solution (1:100 or 1%).
Seedling planting Apply 6 L/ha Mycorrcin to the seed bed at sowing.
Transplanting Dip or drench in a solution of 1 part Mycorrcin to 100 parts water.
Planting/sowing 6 L/ha sprayed onto the soil.
Potatoes at planting 6 L/ha in furrow.
Foliacin Early growth/first cover spray through to harvest 0.5 L/ha in a minimum of 200 L/ha of water with crop protection and/or nutritional spray applications. Re-apply every 10–14 days.
After periods of stress such as drought, extreme heat or phytotoxicity 1 L/ha in a minimum of 200 L/ha of water with crop protection and/or nutritional spray applications. Re-apply every 10–14 days.


For best results apply Mycorrcin to moist soil and/or water in.
Mycorrcin can be mixed and applied with most herbicides and liquid fertilisers.

Foliacin can be mixed and applied with commonly used fungicides and liquid fertilisers.
In times of high stress increase rate to 2 L/ha.

Cover crop programme

Product Timing Application
Digester Cover crops at spray out, prior to planting Apply Digester at 4 L/ha in a minimum of 200 L/ha of water along with herbicide.

Crop trash programme

This programme has been designed to speed up the breakdown of crop residues. The hero is our product Digester. Digester is a microbial stimulator that activates beneficial naturally-occurring saprophytic microbes in your soil that are responsible for crop trash decomposition.

Product Timing Application
Digester Post-harvest 4 L/ha in a minimum of 200 L/ha of water over crop trash to the soil. For crops with heavy disease over-wintering, e.g. asparagus, apply 6 L/ha in a minimum of 200 L of water. Then lightly incorporate.
