Pest & Disease Diagnostic Kits
Lateral flow field tests confirming crop pathogen identity before treatment.
Treating the wrong pathogen wastes chemistry and accelerates resistance in the actual one.
Misidentification of the causal pathogen before crop protection application wastes input cost, misses the target and accelerates resistance in the actual pathogen population present in the field. Jos•Hansen supplies lateral flow rapid test kits confirming late blight, Fusarium, bacterial wilt and key virus diseases from leaf samples at field level in under 30 minutes. Every diagnostic programme includes agronomist training in sample collection, test interpretation and treatment decision protocols, ensuring field diagnostic kits are used correctly and acted on within the intervention window.
30-minute result
Lateral flow immunoassay tests deliver a confirmed pathogen identification from a fresh leaf sample in 15-30 minutes at field level, without a laboratory or power supply. Treatment decisions can be made and acted on the same day as sampling.
Treatment justified
A confirmed pathogen result before application ensures that the selected chemistry matches the actual causal organism. This eliminates the misapplication that accounts for an estimated 25% of crop protection failures in East African vegetable systems.
Virus detection
Lateral flow strip tests for Tomato Yellow Leaf Curl Virus, Bean Yellow Mosaic Virus and Cucumber Mosaic Virus confirm systemic viral infection in symptomatic plants within 20 minutes. Confirmed virus presence changes management from curative chemistry to rogue-and-replant protocols.
Lateral flow tests confirm the pathogen in under 30 minutes.
Lateral flow immunoassay test kits use antibody-coated membranes to capture and visually flag target antigens from plant sap extracted from a fresh leaf sample. No laboratory equipment, power supply or technical skill beyond the supplied protocol is required. Jos•Hansen supplies test kits for the primary crop pathogens affecting East African horticultural, staple and legume systems, including Phytophthora infestans, Fusarium oxysporum, Xanthomonas bacterial wilt, and the major crop virus diseases. Positive identification in under 30 minutes allows same-day intervention before disease spreads further through the crop canopy.
Virus disease confirmation prevents spread through mismanagement.
Systemic virus diseases including Tomato Yellow Leaf Curl Virus and Bean Yellow Mosaic Virus cannot be controlled with curative fungicides or bactericides, and applying them to a confirmed virus-infected crop wastes chemistry and delays the correct management response. Lateral flow virus strip tests confirm virus presence in symptomatic plants within 20 minutes, triggering rogue-and-replant protocols and vector management rather than futile curative applications. Jos•Hansen training programmes teach farm managers to recognise virus-like symptoms and test before spraying, breaking the pattern of misdiagnosis-driven chemistry waste that is common across East African smallholder and commercial systems.
Diagnostic training converts field kits into routine management tools.
A diagnostic kit sitting unused in a shed provides no value. Jos•Hansen agronomists train farm managers and field scouts in the complete diagnostic workflow: symptom recognition, correct sample collection from the right plant part at the right disease stage, test procedure and result interpretation. Training includes decision protocols that link each confirmed pathogen to the correct chemistry class and application timing. Farms where diagnostic kits are used routinely as part of weekly crop walks show measurably lower disease-driven crop losses than farms that rely on visual symptom assessment alone.

Why Pest.
No laboratory needed
Lateral flow tests require only a fresh leaf sample and the supplied buffer. Confirmed pathogen identification is achieved at field level without power, equipment or lab access.
Confirmed before spraying
A positive test result means the selected chemistry targets the actual causal organism, eliminating the misapplication that wastes chemistry and accelerates resistance.
Virus-specific detection
Strip tests distinguish between virus and fungal or bacterial disease, triggering the correct management response where curative chemistry would have no effect.
Outbreak early warning
Routine weekly diagnostic sampling detects pathogens below visible symptom threshold, enabling preventive intervention before disease becomes economically significant.
