Sumitomo Corporation (TYO: 8053) (OTC: SSUMY) and MustGrow Biologics Corp. (CSE: MGRO) (OTCQB: MGROF) (FSE: 0C0) ("MustGrow") have signed an extension to their Exclusive Evaluation and Option Agreement (the "Extension Agreement") to continue developing MustGrow's mustard-based technology across the Americas.

Pursuant to the Extension Agreement, MustGrow has granted Sumitomo Corporation the exclusive right to continue developing MustGrow's mustard-based technologies for preplant soil fumigation, bioherbicide, and postharvest and food preservation for potatoes and bananas in North, Central, and South America for an additional option period (the "Extension Period"). Over the span of the initial option period, Sumitomo Corporation's evaluation efforts demonstrated positive levels of efficacy utilizing MustGrow's technology in comparison to certain synthetic chemical standards.

The global crop protection chemicals market size was valued at USD 63.7 billion in 2020, and is projected to reach a value of USD 74.1 billion by 2025.⁽¹⁾ The growth of this market is attributed to the increasing need for food security of the growing global population. A large growth market is biopesticides, which are pesticides produced naturally, with minimum usage of chemicals. Due to rising environmental concerns and awareness of the pollution potential and health hazards of many synthetic conventional pesticides, the demand for biopesticides has been rising steadily in all parts of the world.
