• Disease control of root-rot Aphanomyces in greenhouse testing across a range of economic rates.
• Plants treated with MustGrow's biopesticide were robust in plant and root system health.
• Aphanomyces is a soil-borne root-rot disease that destroys pulse crops (peas, lentils, and legumes).
• 90% of Saskachewan pulse crop fields have shown Aphanomyces symptoms (2019).

Saskatoon, Saskatchewan--(Newsfile Corp. - May 12, 2021) -  MustGrow Biologics Corp. (CSE: MGRO) (OTCQX: MGROF) (FSE: 0C0) ("MustGrow") is pleased to announce successful greenhouse efficacy results of its patented mustard-derived biopesticide on Aphanomyces euteiches zoospores ("Aphanomyces") via an independent third party. Control in greenhouse soil was recorded across a range of economic application rates. MustGrow will advance to larger scale field tests in 2021 to be conducted under the recently-announced collaborative Canadian field trials program with NexusBioAg, a division of Univar Solutions Inc. Study results and applicability are patent-protected under MustGrow's existing suite of issued patents.

MustGrow's crop protection technology has consistently demonstrated efficacious benefits similar to chemistry-based "synthetic chemical" products without the harmful safety profile often associated with some synthetic chemical products. The development of safe and effective biopesticides will be critical for future food security and environmentally sustainable agriculture.

Greenhouse Soil Study Highlights

• Control in greenhouse soil was recorded across a range of economic application rates.
• Initial soil samples were infested with Aphanomyces prior to applying MustGrow's mustard-derived TerraMG.
• Plants treated with TerraMG were increasingly robust - in plant and root system health - commensurate with application rate.

MustGrow's remarkably safe and effective organic biopesticide is plant-based - harnessing the mustard seed's natural defense mechanism to control diseases, insect pests, and weeds. This greenhouse study builds on MustGrow's previously reported (January 2021) 100% control of Aphanomyces in laboratory tests at economic application rates within 24 hours.

About Aphanomyces - Root-Rot Disease

Aphanomyces is a water mould pathogen responsible for root-rot disease, infecting a variety of peas, lentils and other legumes collectively referred to as pulse crops. The disease causes severe root damage and wilting, with yield losses ranging from 10% to 100% in infected fields ⁽¹⁾. Canada is one of the world's largest producers (~9.2 million tons; 2019) and exporters of pulse crops ⁽²⁾. Industry experts conservatively estimate $20 million in annual pulse crop losses in Canada and $100 million globally caused by Aphanomyces ⁽¹⁾. The Province of Saskatchewan has been hit particularly hard, with 90% of fields showing Aphanomyces symptoms in 2019 ⁽³⁾. Current treatment measures cannot control Aphanomyces - they are only able to slow down the spread and reduce the incidence and severity of the disease. Further, there are currently no genetic cultivars available with complete Aphanomyces resistance ⁽⁴⁾.

Plant-Based Crop Protection for Plant-Based Protein

MustGrow feels it makes both logical and ecological sense to protect plant-based protein crops with plant-based crop protection inputs. MustGrow's product is a preplant soil treatment, meaning application to the soil occurs before crops are planted. Application of MustGrow's biopesticide returns organic plant material to the soil through this preplant treatment process as a potential alternative to using synthetic chemicals.

The global plant-based protein market size is projected to grow from US$12 billion in 2019 to US$28 billion by 2025 (CAGR of 15%) ⁽⁵⁾. This is attributed to several drivers, predominantly rising consumer health-consciousness, growing prevalence of protein-rich pulse crop food products, and technological innovations in plant-based protein extraction. To accommodate the rise of plant-based protein demand, the global pulse crops market is anticipated to grow from US$16.2 billion in 2017 to US$24.3 billion by 2025 (CAGR of 5.2%) ⁽⁶⁾.
