2. 1. Non-toxic and powerful bio-pesticide for the control of
Powdery Mildew and other foliar and soil-borne
diseases
2. Highly-concentrated, yet very gentle, water soluble
fertilizer
3. Tank buffer and water conditioner to prevent alkaline
hydrolysis.

3. • Nutrol contains over 50% P2O5 and 32% K2O, making it one of
the most concentrated water soluble fertilizers available.
• Nutrol is also very gentle—it has the lowest salt index of any
fertilizer—and will not cause phytotoxicity, even at high
concentrations.
• And since Nutrol is nitrogen-free, you can manage nitrogen
requirements independently.
• Nutrol is suitable for foliar, soil and drip irrigation
applications.

5. • Nutrol is a true tank buffer. Nutrol can acidify and maintain the
pH of tank solutions throughout application.
• Nutrol buffers solutions to the pH recommended for most
pesticides, insecticides and herbicides. NOTE: The pH of a 1%
aqueous solution of Nutrol is 4.5 +/- 0.3.
• Nutrol prevents alkaline hydrolysis, which can negatively impact
the performance of commonly used pesticides.
• One-percent (1%) solutions of Nutrol in the pesticide tank will
ensure optimal performance of each component.

6. • In these experiments the researcher added incremental amounts of Nutrol to
alkaline water.
• As you will note, once the pH was at equilibrium, the pH stays in a very narrow
range.
• Typically, a 1% solution of Nutrol will buffer the pH of water within the narrow
equilibrium range.

7. Nutrol can be used to control and eradicate powdery
mildew on Apples, Cucurbits, Grapes, Mangoes,
Peppers, Stone fruit and Tomatoes.
Nutrol is labeled for the control of several soil-borne and
foliar diseases when applied with any of the Prudent
family of fertilizers.

8. • Nutrol is the ideal “partner” product for alternation and
tank mixing with other EPA registered pesticides.
• Nutrol, when used in alternation with other labeled
fungicides, can prevent the formation of resistant
powdery mildew strains.
• Nutrol is safe for the applicator and the environment.
Powdery Mildew Crop Protection
Do NOT use Nutrol with copper fungicides or other compounds that warn against mixing with low pH products.
