SR3 Benefits

  • Improved crop quality and yield
  • Increased availability and uptake of nitrogen and phosphorus and other nutrients
  • Improved root and shoot development through the production of phytohormones
  • Improved plant vigour for better disease resistance
  • Reduced reliance on synthetic nitrogen inputs
  • Builds biologically active soils


A range of liquid formulations of plant growth promoting rhizobacteria each tuned and tested for optimum performance in specific field crops. These bacteria are produced in sterile laboratory conditions under stringent QA control, each bacteria species in consortia is individually packed to ensure the product quality.

Field trials have shown significant yield increases in a range of root, vegetable and cereal crops. More recently in 2019-2021 a series of field scale experiments were undertaken using SR3 WHEAT to quantify the scope for field N modulation and the subsequent enhancement of plant microbiome. The yield uplift between the untreated and various SR3 treated areas was found to be statistically significant in all trials regardless N input.

Please see attached trial sheets for detailed information on experimental field results.

Plant growth promoting rhizobacteria (PGPR) have the ability to fix atmospheric nitrogen and unlock soil-bound phosphorus and potassium as well as other nutrients. They also produce phytohormones to promote better root and shoot development. Beneficial bacteria work in synergy with AMF, which captures and transports nutrients to host plants. PGPR support a robust plant immune system for healthier crops.

PlantWorks’ research has shown that different species of PGPR give benefits to different plant types. The bacterial strains in SR3 have been specifically selected and formulated to give maximum benefit to each specific crop.


Suitable for application with standard spray equipment including boom sprayers at a minimum of 200L of water per hectare. We recommend nozzle selection and low-pressure settings to achieve coarse to medium spray quality and maximum soil coverage. Allow 3 days before or after applying ground or foliar nitrogen.

This product contains live microorganisms and is not suitable for tank fertiliser mixing. Although bacteria are not affected by most pesticides, tank mixing should be avoided due to different spraying targets and settings (SR3 spraying soil with coarse droplets before the rain).

Product size: 5-hectare treatment includes: 4 x 50ml sachets of bacterial inoculant, 1L bottle of biostimulant and a sachet of dechlorinating agent for water treatment.

Application time:

Winter wheat GS25-31– apply when the crop is at the late tillering / early stem elongation stage in March, preferably before the rain.

Spring wheat GS13-19 – apply post-emergence until early stem elongation, preferably before the rain.

Bacterial species supplied at 108 CFU per ml.
