Grow more.
Input smarter.

The complete C4L biostimulant field application guide for South African commercial farmers, proven phenological timings and dosages across citrus, fruit crops, vegetables, maize and small grains.

POCKET FIELD GUIDE

Built for South African Conditions

C4L primes crops against abiotic stress, critical for SA's increasingly erratic rainfall patterns and water-scarce growing regions like the Western and Northern Cape.

Drought & heat stress tolerance

With fertiliser and crop protection costs under pressure, C4L improves nutrient uptake efficiency — so every rand of input goes further towards yield.

Rising input costs

Fruit size, colour, firmness and shelf life are non-negotiable for EU and UK export markets. C4L's programme targets these quality parameters at the right growth stage.

From transplant through to canopy establishment, C4L supports root growth and early plant vigour — closing the gap between planting and productive yield.

Early vigour & root development

ABOUT THIS GUIDE

Results-based insights across
every key South African crop.

This application guide outlines clear phenological timings and dosages to support early vigour, root development, stress tolerance and yield potential  based on field-proven data gathered across South African growing regions.

With this final guide, the BioRevolution Pocket Guide Series now brings together practical, results-based application insights across key crop groups, from citrus and fruit crops to vegetables, maize and small grains.

Each guide is built on real-world evaluations and designed to support consistent decision-making, accurate application and reliable performance throughout the season.

Biostimulants for South African citrus & fruit

South Africa's citrus, deciduous and subtropical fruit sectors export to over 100 countries, making fruit quality and consistency mission-critical. C4L's phenology-aligned application programme targets fruit set, calcium uptake, colour development and shelf life at precisely the right growth stages — from full bloom through to harvest.

Used across the Western Cape, Limpopo, Eastern Cape and KwaZulu-Natal growing regions by commercial producers chasing export-grade results.

C4L for maize, small grains & field crops

As input costs climb and climate variability increases pressure on the South African grain belt, C4L provides a cost-effective tool for improving germination, tillering, stress tolerance and grain fill. Applied at the 4–6 leaf stage and flag leaf, it supports yield potential without increasing chemical input load.
Relevant for maize producers in the Free State, Mpumalanga and North West, and wheat and barley growers across the Swartland and Southern Cape.
