Aerial view of KEPHIS Nakuru

KEPHIS Nakuru station was established as a national center for seed quality control in 1979 at 0°17'43.6_S 36°11'03.7_E Lanet in Nakuru. This was as a result of the relocation of the seed laboratory that was based at NARL Nairobi to the current location in Lanet. It was then called the National Seed Quality Control Service (NSQCS). We have evolved with time and in 1996, When KEPHIS was formed in 1996, it took over the activities of NSQCS. The station ensures KEPHIS mandate is achieved mainly in eight counties of the country as shown in the figure below:

Our customers range from local farmers, seed companies, Public and international organizations. As a customer-focused laboratory, operating in a world of changing needs and opportunities, we innovate constantly to provide high-quality service.

The laboratory has offered seed testing services continuously since 1944. It provides ISTA testing for a wide range of crops and tests including sampling, purity and other seed determination, germination, viability, moisture content, weight determination, vigor, and Seed Health tests.

The laboratory provides the following services apart from the core function of seed testing:-

  1. It hosts international workshops
  2. It offers consultancy services on topics related to seed testing
  3. offer specialized or general training to a wide variety of audiences including seed analysts, industry staff(local and International), and students from tertiary institutions

As an accredited laboratory, we improve our quality management system continuously to respond to the needs of a changing global seed world.

Summary facts about KEPHIS Seed Testing Laboratory

  • Is the only National seed testing laboratory in Kenya
  • Offers testing services for more than 250 species of crops, vegetables, flowers, and trees
  • Able to testabout200 pathogens (fungi, bacteria, and viruses)
  • Is a reputable seed industry source for international workshops and short courses on seed quality.
  • Has served as Kenya’s seed industry leader in seed testing for 69 years

Plant Health Laboratory

The plant health laboratory was established in 2014 and to date, more than five thousand samples have been tested for different pathogens and our clients advised accordingly. The health of seed refers primarily to the presence or absence of disease-causing organisms such as fungi, bacteria and viruses, and animal pests, such as eelworms and insects although Physiological conditions such as trace elements deficiency may be involved. The laboratory takes pride in its modern equipment which enable rapid and reliable results being released to the client within the set timelines. This is based on well-researched methods that enable reproducible detection of the presence or absence of pathogens in plant material and soil.

Our customers

Our customers range from local farmers, seed companies, county governments, public and international organizations. As a customer-focused laboratory, operating in a world of changing needs and opportunities, we innovate constantly to provide high-quality service. We listen and endeavor to meet our customers’ needs by always expanding our scope of testing based on their needs. The laboratory has the following units:

Molecular Testing Unit

This laboratory makes use of molecular techniques to ensure samples are tested rapidly and reliably based on the detection of both DNA and RNA of pathogens in samples. This is achieved using both Real-time PCR and Conventional PCR which gives high reliability of results.

Mycology Testing Unit

The inspection of plant materials to observe fruiting structures of fungi and the effects of the fungi on the physical appearance if any are observed for quicker decision making by our staff. The fruiting bodies such as acervuli, pycnidia, perithecia, sclerotia on the plant surface, or submerged in the plant tissue can be seen by the naked eye as well as using sophisticated microscopes. Our laboratory is well equipped with both stereomicroscope and compound microscope as well as computer attached trinocular microscopes and fluorescent microscope. These enable our staff to accurately identify fungal to species level. Our large capacity walk-in Near Ultraviolet incubation room enables faster sporulation of fungal which makes fungal detection rapid.

Nematology Testing Unit

This is the youngest of the units in the plant health laboratory following the unending needs to meet our clients’ needs. The unit was established last year in 2019 and to date over six hundred samples have been tested. Nematodes are a diverse group of worm-like animals that are found in virtually every environment both as parasitic and free-living organisms. Their impact in agriculture production has been underestimated over the years but in recent days, their economic damage has come to be acknowledged hence the need to identify and manage them properly. General statistics globally puts reduced yield loss due to Nematodes at 11% reducing production by millions of tonnes every year.
