Pest & Disease Management

Pest & Disease Management

Integrated pest management programmes combining monitoring, biocontrol and targeted chemistry for African crop systems.

Reactive pesticide use is the most expensive and least effective pest management strategy.

African farmers spend an estimated USD 1 billion on pesticides annually — yet pest-driven yield losses continue to increase. The dominant pattern is reactive: spray on a calendar schedule or after visible damage is already present. By the time feeding damage is visible, the economic injury has already occurred. Integrated pest management changes the economics: scout first, establish economic thresholds, intervene with the most targeted available tool at the optimal time. Jos•Hansen supplies the scouting tools, diagnostic kits, biocontrol agents and IPM-structured chemistry portfolios that make this approach practical at scale across East and Southern African farming systems.

Biocontrol agents reduce pesticide dependency without sacrificing yield.

Entomopathogenic fungi such as Beauveria bassiana and Metarhizium anisopliae are now field-proven for control of fall armyworm, thrips and soil-dwelling pests in African crop systems. Our biocontrol portfolio integrates into conventional IPM programmes as alternation partners, extending efficacy windows while reducing chemical input costs. Jos•Hansen provides technical support for biocontrol introduction, application timing and performance monitoring across the season.

Disease forecasting alerts growers before outbreaks establish.

Responding to visible disease symptoms means the economic damage is already done. Our disease forecasting tools — weather-based risk models and electronic scouts — alert farm managers to high-risk windows for fungal and bacterial outbreaks before visible symptoms appear. Preventive intervention at the right growth stage costs a fraction of curative treatments applied after disease has spread through the canopy.

Field diagnostics confirm the pathogen before treatment decisions are made.

Treating for the wrong pathogen wastes chemistry and accelerates resistance to useful actives. Our lateral flow diagnostic kits confirm the causal organism — bacterial, fungal or viral — from leaf samples at field level in under 30 minutes. Jos•Hansen trains farm managers and extension officers in diagnostic kit interpretation, turning point-of-care pathogen identification into a routine crop management practice.

Key active ingredient classes in our portfolio.

Our pharmaceutical selection covers every major drug class used in livestock and companion animal practice — from macrocyclic lactones for parasite control to fluoroquinolones for resistant bacterial infections and meloxicam for perioperative pain.

Pharmaceutical supply done responsibly.

Supplying pharmaceuticals to livestock producers carries a responsibility to food safety, antimicrobial stewardship and regulatory compliance — obligations Jos•Hansen takes seriously on behalf of every client.

Economic Threshold Intervention

IPM programmes establish population thresholds before any intervention — ensuring chemical input is applied only when economically justified, reducing unnecessary spray events by up to 40%.

Resistance Delay

Rotating chemistry classes with biocontrol intervals prevents the resistance selection pressure that has rendered several key actives ineffective for fall armyworm control in East Africa.

Pathogen-Confirmed Treatment

Lateral flow diagnostic kits confirm causal organism identity before chemistry selection — preventing misdiagnosis that wastes product and misses the target.

Reduced Residue Risk

Biocontrol agent integration reduces chemical application frequency, directly lowering end-of-season residue levels on export-destined crops and reducing maximum residue limit exceedance risk.

The productivity numbers that matter.

Pharmaceutical investment in livestock is only justified by measurable productivity return — these are the figures that validate strategic veterinary pharmaceutical programmes.
