Key Benefits

Key Components

Digester consists of a combination of bacteriocins, enzymes, signal molecules and secondary metabolites from the fermentation of beneficial bacteria.

Mode of Action

Digester is made from fermentation extracts of the beneficial soil microbe Pseudomonas putida, which work by activating the saprophytic fungi in the soil involved in decomposition.

Digester is used to promote the rapid breakdown of leaf litter, cover crops, old roots and post-harvest crop trash in horticultural crops.

Applied directly to residual plant material, Digester activates decomposition microbes already present in the soil.

Digester reduces disease on the following crop by completely decomposing the plant material that plant pathogens use as a host over winter.

Directions for Use

Wine grapes, Table grapes
Target
Crop residue decomposition
Timing
After leaf fall, After pruning
Rate

3-4 L per sprayed ha in a minimum of 200 L of water

Critical Comments

Apply Digester directly on to leaf litter, prunings and other crop residues.

Requires soil moisture/rain and active soil biology.

Digester can be tank mixed with herbicides and fertilisers.

Digester can be applied through fertigation and overhead irrigation.

In low organic matter soils, low fertility soils, after long dry spells or high crop residue levels add technical grade ammonium sulphate at 30 kg/ha.

For best results avoid applying Digester in the heat of the day.

Treated crop residues may be lightly incorporated where possible to maintain moisture.

Use the higher rate in blocks with heavy overwintering disease pressure, compacted or waterlogged soil.

Pome fruit, Stone fruit, Kiwifruit, Avocados, Citrus

Use the lower rate in soils with low organic matter.

Compatibility

Digester is compatible with most commonly used herbicides, fertigation nutrients/nutrient sprays and suspension fertiliser.
