Biocast applications:



Whether your plants are in the ground, in pots, or grown hydroponically, Biocast can be used to enhance their health and productivity. Currently our customers include market gardeners, flower growers (both native and non-native, including orchids), garlic growers, avocado orchards, medicinal cannabis growers and vineyards. Small trials have also been very successful on blueberries and citrus. Two key benefits our customers have noticed are 1) plants are more robust, and have greater vigour – this looks like stronger and longer flower stems, larger flower heads, fuller seeds and fruit, and higher fruit set; and 2) there has been a profound reduction in pest and disease attack, resulting in higher saleable yields and improved shelf life of their product, as well as a reduction in chemical pest control and fertiliser. See our grower stories for more on this.

Signs your plants could benefit from the addition of microbes

  • Plants show signs of nutrient deficiency, such as discolouration of the leaves or fruit not filling properly
  • Soil tests show high total nutrient but low available or dissolved nutrient
  • Plant leaves are prone to insect attack
  • Plants are afflicted by fungal and bacterial diseases such as powdery and downy mildew, black anthracnose, black spot on roses, or phytophthora root rot
  • Plants wilt easily
  • Low quality harvests
  • Low yields not explained by factors such as water stress
  • Plant growth/ development seems stunted (not growing, not flowering etc)
  • Plants suffer transplant shock
  • Low seedling establishment rate and damping off (pithium)

Suggested uses

Foliar spray


  • Supplies plants with a quick health boost
  • Fulvic acid conveys minerals across the cell wall
  • Provides competition on the leaf and fruit surface to fungal and bacterial diseases
  • Whatever drips off will also inoculate the soil for a double effect

What it is good for

All plants actively growing and producing. We recommend not applying Biocast during flowering periods for commercial crops such as avocados.

How to apply

  • You can use your existing sprayer, but we recommend not using this if it is also used for spraying poisons. As it is a living liquid, a big dropper is required rather than a mist
  • Combine Part A and Part B in your sprayer/ irrigation system, and dilute with water 20:1
  • Apply to leaf surface so there is at least 80% coverage, just to the point of runoff
  • The volume you will need per hectare and the frequency of application will vary depending on what you are growing. Please contact Lee if you would like to discuss your situation. As a general indication we recommend weekly application for high production vegetables such as leafy greens; fortnightly application for other vegetables; a monthly application for maintenance of crops such as cut flowers and blueberries; and three to five applications per growing season for fruit trees and grape vines.

Transplant drench


  • Improves transplant success rates, minimising losses.
  • Microbes and their byproducts cut transplant shock.
  • Root-stimulating hormones encourage new root growth, aiding rapid establishment.
  • Protection against root diseases.

What it is good for

  • Transplanting seedlings to pots or between pots in a nursery setting
  • Transplanting plants from pot to ground

How to apply

In a tub, mix Part A and Part B and dilute with water 20:1. Less dilution is OK – applying straight will do no harm.

The longer the plant has been in the pot the longer it needs to sit in the solution. Generally the root ball just needs to be soaked through, 5-10 minutes. Up to 24 hours is required for severely root bound plants, with the pot off.
