Different places/location have differing water pH. Do they have a direct effect on the efficacy of the biopecticide?
Dear Jactone:
For entomopathogenic fungi such as Beauveria bassiana and Metarhizium anisopliae water is the carrier vehicle for spores, this must be clean with pH close to 7.0, different values may alter the spore germination.
Best wishes,

As said previously fungal biopesticides needs pH 7 or 6.5 for better results. For foliar sprays, pH shall be a crucial factor.
Thank you for the answer.
Allow me to ask Luis and Jay.
If that be the case, Should that translate to advising the customer/farmer to be adjusting there water pH to the favorable condition?
Dear Dr. Jactone,
Biopesticides require specific conditions in order to work optimally. pH can affect bioantagonistic activity of an organism. Sporulation ability of the fungus, and the ability of producing secondary metabolites for bacteria are very influenced by water pH. We recommend to using a pH between 6.5 to 7.3.
It is a challenge to create a biopesticide that is easily applied to a variety of conditions. Because consumers / farmers want a product that is easy to use
Water to spray bio or conventional pesticides must be of good quality: mainly without suspended particles or algae growth and pH around 7. Water pH is is controlled primarily by inorganic carbon content, A pH from 6.5 to 7.0 is an indication that only CO2 from surrounding air is maintaining it and no other sources of acid or basic reaction, which could impair the action of the biological or chemical pesticide.
Regards.
