In the realm of agricultural pest control, the demand for effective and eco-friendly solutions is ever-increasing. Among the many threats to crop health, powdery mildew stands out as a particularly challenging adversary. Enter Bionatrol-M, a revolutionary natural pesticide designed to combat this pervasive issue. This blog delves into the detailed findings from various trials conducted to evaluate the efficacy of Bionatrol-M in controlling powdery mildew on crops.

What is Bionatrol-M?

Bionatrol-M is a biopesticide formulated from soybean oil, known for its potent fungicidal properties. This natural solution offers a safer alternative to conventional chemical pesticides, posing minimal risk to human health and the environment. Developed by NTS Research & Inc., Bionatrol-M is engineered to combat a range of fungal diseases, including powdery mildew.

Trial Design and Methodology

To assess the effectiveness of Bionatrol-M, multiple trials were conducted on commercial cherry orchards in the Creston Valley during the 2007 growing season. These trials involved different varieties of cherries, including Lapins and Staccato, under varying environmental conditions.

Trial Setup

  • Trial 1 and 2: Included six treatments with single tree reps in a randomized complete block design. Treatments were applied using a handgun to run-off, with approximately 5 liters of solution per tree.
  • Trial 3: Similar setup with additional environmental factors considered, such as covered systems to simulate real-world agricultural scenarios.


  • Control: Untreated
  • Standard Fungicides: Cabrio and Pristine
  • Natural Solutions: Bionatrol-M and Purespray Green
  • Combination Treatments: Bionatrol-M + Cabrio, Purespray Green + Cabrio

Results and Findings

Disease Incidence and Severity

  • Trial 1: Untreated control showed 4% disease severity. Treatments with Cabrio, Bionatrol-M, and their combinations significantly reduced disease incidence.
  • Trial 2: Very low disease pressure with untreated controls showing 0.4% infection. No significant differences were observed among treatments.
  • Trial 3: Higher disease pressure with untreated controls showing 10.5% infection. All treatments significantly reduced infection, but no additive effect was observed from combining oils with standard fungicides.

Phytotoxic Effects No signs of phytotoxicity were observed in any treatments across all trials. This indicates that Bionatrol-M is safe for use without causing harm to the plants.


The trials demonstrated that Bionatrol-M is effective in controlling powdery mildew, particularly under high disease pressure. Its use as part of an integrated pest management program could offer a sustainable solution for farmers. The absence of phytotoxic effects further underscores its potential as a safe and eco-friendly fungicide.


Bionatrol-M emerges as a promising natural pesticide for managing powdery mildew in crops. Its efficacy, coupled with safety and environmental benefits, makes it a valuable tool in sustainable agriculture. Future research should continue to explore its application across various crops and environmental conditions to fully harness its potential.
