Biocast+ application

Ways you can use Biocast+

There are four main ways we recommend the use of Biocast+. They are as a foliar application, as a soil application, as a transplant drench, and as a seed inoculate. Read on for more information on the benefits of each, what situations each is best for, and how to apply it.

On the leaves (foliar)

Benefits: 

  • Direct contact of microbes on the leaf surface helps suppress pathogens and diseases by introducing competition. It creates a more balanced leaf surface ecology where no one thing is as likely to get out of check.
  • Fulvic acid takes the minerals that are bonded with it through the plant cell walls for an immediate effect.
  • There is a double effect because whatever drips off the leaf lands on the ground and is usable by the plant’s roots, making it our preferred application.
  • This method allows plants to develop their own soil microbe communities at a level that is sustainable to them (healthy plants build healthy soils!).

What to use this method on:

  • This is our favourite application as Biocast+ is safe to apply to the leaf surface of all plants.
  • Plants suffering from fungal diseases such as powdery mildew and black spot, and those prone to such diseases (prevention is easier that a cure).
  • Plants looking poorly that need a quick boost.
  • Fast growing plants such as vegetables.

How to apply:

  • Use a watering can or sprayer with a large droplet size (to protect the microbes).
  • In your vessel, add part B to part A and dilute with water 20:1.
  • Spray in the coolest part of the day to maximise leaf contact time before evaporation.
  • Aim for 70-80% leaf coverage just to the point of runoff. If you are using a watering can this is roughly a regular walking pace while watering.
  • For maintenance applications apply when the plant is actively growing, or once a fortnight through the growing season, up to once a week for very fast growing plants like leafy green vegetables.

On the soil

Benefits:

  • Hormones boost root growth.
  • Microbial associations assist plant stability by helping to create a beneficial soil environment, for example by buffering pH and acting like a water sponge.
  • Microbes and their enzymes promote maximum nutrient uptake.
  • Protects against soil diseases by introducing microbial competition, making it less likely for one species to get out of check.

What to use this method on:

  • Soils contaminated with microbial diseases such as pithium root rot and phytopthera
  • Growers using fertigation
  • Enhancing potting mixes

How to apply:

  • Add part B to part A as per mixing instructions and dilute 20:1 with water.
  • Apply as a drench or through drip irrigation (fertigation) to the root zone.
  • Water over newly planted seeds (see also seed inoculate, below).

As a transplant drench

Benefits:

  • 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.
  • Inoculates the soil around the new plant with beneficial microbes.

What to use this method on:

  • Use when planting out seedlings
  • When transplanting mature plants
  • When transplanting small seedlings in a nursery.

How to apply:

  • In your bucket combine part A and part B as per mixing instructions. Dilute with water 20:1.
  • Submerge root ball in Biocast+ prior to planting.
  • Saturation time depends on the size of the root ball. E.g. Small seedlings 3-5 minutes, large mature trees up to 2 hours.

As a seed inoculate

Benefits: 

  • Puts beneficial microbes where they are needed from the start of the plant’s life.
  • Can promote rapid establishment of the seedling.

What to use this method on:

  • Any seed – however, you may find it impractical when hand planting smaller seeds.
  • Effective way to spread microbes in a broadacre/ pasture setting

How to apply:

  • Use undiluted.
  • Immerse seeds to coat. Soaking not required for inoculation.
  • For large quantities of seed an auger or cement mixer can be used to coat the seed. As little as 5L per tonne is required as long as the Biocast+ contacts each seed.
