Kichawi Kill: Striga Bioherbicide

Mitigating Africa’s worst pest threat to food security by revolutionizing crop protection with a biological and sustainable weed control alternative.

This technology is a selective biological herbicide that farmers apply as a seed coating to boost their crop yields. This groundbreaking innovation is one of the first bioherbicides to be commercialized worldwide. It uses strains of a specific Kenyan fungus, Fusarium oxysporum f.sp. strigae, which have been selected for their ability to over-produce certain amino acids that kill Striga (witchweed) without harming maize. Normally, Fusarium oxysporum isn’t strong enough to protect crops from Striga. However, by choosing strains that over-produce specific amino acids, the fungus can effectively reduce Striga infestations and restore crop yields. This is the first technology to combine the benefits of amino acid inhibition with fungal pathogens.

This technology is pre-validated.

ROI: $$$ 42—56 %

Yield increased

Problem

Striga, an invasive parasitic weed, attacks the roots of staple crops like maize and sorghum, reducing crop yield by 20–100%.
50 million hectares of croplands (40 million farms) in sub-Saharan Africa show Striga infestation, causing $9+ billion in crop loss annually.
Striga plants produce over 50,000 seeds per season, adding to the soil seed bank.
The seeds of striga can spread easily across farms and from one farm to the next through wind, human and animal traffic, and farming tools.

Solution

Kichawi Kill is a groundbreaking solution for managing Striga and other global weed problems.
Using this herbicide has resulted in a 42-56% increase in crop yields.
The approval of the fungi seed coating product has significantly reduced its cost and increased its shelf life.
This technology offers a safe, effective, and affordable alternative to traditional chemical herbicides.

Key points to design your business plan

This technology is beneficial for resellers and farmers

Resellers

Selling the Striga bioherbicide not only provides a valuable product but also fosters closer engagement with users while significantly reducing yield losses during maize cultivation.

To successfully navigate this market, you need to know where to source the bioherbicide in bulk, identify efficient transportation methods, and explore suitable storage facilities. As the technology is available in several countries, including Cameroon, Ethiopia, Kenya, Uganda, and Ghana, estimate the delivery cost to your country and account for import clearance and duties if relevant.

Your potential customer base includes small local retailers, development projects, producers, and producer cooperatives or associations.

For farmers, the technology is priced at 15.50 USD to treat 10 kg of maize seed, 7.25 USD for 5 kg, and 3.10 USD for 2 kg.

Establishing strong partnerships with Striga bioherbicide manufacturers and transportation providers is crucial.

Farmers

Using this Striga bioherbicide offers a safer and more environmentally sustainable alternative to chemical pesticides, reducing exposure to harmful chemicals for agricultural workers while enhancing maize productivity.

Given its availability in several countries, including Kenya, it is essential to factor in delivery expenses and possible import duties.

Regarding cost estimation, the technology is priced at 15.50 USD to treat 10 kg of maize seed, 7.25 USD for 5 kg, and 3.10 USD for 2 kg.

To maximize outcomes, it is advisable to combine this technology with other agricultural practices and to use improved maize variety.
