Crop Protection
Chemical and biological solutions protecting African crops from pests, diseases and environmental stressors.
African farmers lose up to 40% of their harvest every season to pests and disease.
Crop losses from pest pressure, fungal disease and post-harvest spoilage represent the single largest financial burden on African smallholder and commercial farmers. In East Africa alone, fall armyworm has caused losses exceeding USD 3 billion annually across maize-producing countries. At the same time, indiscriminate pesticide use has accelerated chemical resistance, degraded soil biology and left residue traces on export crops that trigger border rejections. Jos•Hansen supplies evidence-based crop protection portfolios — fungicides, herbicides, insecticides and biocontrol agents — that maximise yield protection while managing resistance and meeting the residue standards of export markets.
Chemistry rotation prevents resistance and protects crop value.
Rotating between active ingredient classes is the most effective resistance management strategy available to African farmers. Jos•Hansen agronomists design season-long crop protection programmes that sequence modes of action — preventing the selection pressure that causes resistance to build. Every programme is built around the specific crop calendar, disease pressure history and market standards of the target region.
Biological control agents reduce chemical dependency without yield compromise.
Biocontrol agents — entomopathogenic fungi, predatory insects and microbial antagonists — are now cost-competitive with conventional chemistry in several high-value African crop systems. Our biological portfolio integrates into conventional programmes as alternation partners, extending efficacy windows while reducing residue risk for export-market crops. Jos•Hansen provides technical support for biocontrol introduction and performance monitoring.
Agronomist advisory turns product supply into production outcomes.
Supplying crop protection products without advisory is a lost opportunity. Jos•Hansen agronomists work directly with farm managers and extension officers to develop site-specific crop protection programmes, calibrate application equipment and train field teams in correct PPE and product handling. Our advisory service converts chemistry investment into measurable yield protection outcomes across the season.
What Jos•Hansen delivers beyond the machine.
Supplying the equipment is step one. The clinical programme only works when commissioning, physics, training and service are executed to the same standard.
Turnkey commissioning
From site survey and civil requirements through shielding design, beam data acquisition, TPS integration and regulatory submission — our certified medical physicists manage the full process. No system treats a patient without our acceptance sign-off.
Multi-vendor independence
We supply Accuray, Varian, Elekta and PTW — advising on the system that fits your patient volume and clinical programme, not a manufacturer's sales quota. Our recommendation is always clinical, not commercial.
Post-warranty lifecycle continuity
When manufacturer service contracts expire, Jos•Hansen continues. Planned maintenance, QA audits and genuine spare parts sourcing sustain radiotherapy systems for 5–10 years beyond the standard OEM support period.
Regulatory compliance support
We prepare radiation safety assessments, equipment qualification reports and QA programme documentation for submission to national regulatory authorities across East and Southern Africa.
Measurable clinical performance.
Every system we install is measured against published clinical and dosimetric standards. These are the numbers your medical physicists and clinical governance teams will audit.
End-to-end targeting accuracy of CyberKnife S7 and TrueBeam, measured to ISO 9283 — the international standard for industrial robot repeatability applied to radiosurgery.
Local control rates for radiosurgery across selected indications, consistent across peer-reviewed clinical literature (Int J Radiation Oncology, 2019–2024).
Reduction in mean dose to organs at risk with IMRT and VMAT compared to conventional 3D conformal radiotherapy, per published dosimetric studies.
From chemistry selection to resistance management.
Our crop protection portfolio covers fungicides, insecticides, herbicides and biological agents — selected for African conditions, registered in-country and supported by agronomist advisory for correct application and rotation planning.
Global manufacturers. African execution.
Every product we supply is sourced from world-class manufacturers and backed by Jos•Hansen's local installation, training and service capability across East and Southern Africa.
