Trilogy Botanical Fungicide / Miticide

Thorough coverage is essential for good disease and mite control. Trilogy prevents fungal attack of plant tissue and contact activity to mite pressure on the plant. Avoid excessive run off of spray for maximum control.

Thorough coverage is essential for good disease and mite control. Trilogy prevents fungal attack of plant tissue and contact activity to mite pressure on the plant. Avoid excessive run off of spray for maximum control. For optimal performance do not mix with cold water (less than 45° F). Do not apply to wilted or otherwise stressed plants, newly transplanted material or crops prior to root establishment.

If using this product on a sensitive crop, plants with tender tissue or in conjunction with beneficial insects conduct a small scale test first to determine sensitivity or compatibility.

As with other oil based products exercise care in timing applications in the early morning or late evening to minimize the potential for leaf burn.

This product is OMRI Listed, therefore it is determined by the Organic Materials Review Institute (OMRI) to be suitable for use in certified organic production.


Trilogy is a botanical fungicide / miticide that controls a wide range of foliar diseases and selected mite species.

  • Consistent performance.
  • Excellent leaf coverage.
  • Meets National Organic Program (NOP) standards.
  • Organic Materials Review Institute (OMRI) listed.
  • Biorational pesticide. Low risk to people and non-target animals.

Trilogy is compatible with the environment and its inhabitants. Field workers can re-enter treated areas after only 4 hours. Trilogy also has a 0-day pre-harvest interval - it can be applied up to and on the day of harvest.

Using Trilogy for More Effective Pest Control


Uniform coverage of Trilogy provides both contact and curative fungicide activity. Trilogy coats and desiccates fungal spores to halt the disease cycle. Trilogy can be used as a curative fungicide if applied early in the disease cycle, before major disease symptoms develop. Trilogy can arrest early disease development and prevent establishment of pathogens.

Trilogy offers no systemic fungicide activity, so it must be applied to new growth to maintain effective control. Therefore multiple applications of Trilogy may be needed on a weekly basis to effectively protect fast-growing vegetable and tree crops.


Trilogy controls mite populations on vegetable crops and tree fruit. Its mode of action requires uniform coverage of the target crop to eliminate mite populations by suffocation. Trilogy also provides activity on certain mite species eggs, but is soft on beneficial predator mites.


Trilogy will knock down a light population of soft-bodied insects.

Tank Mixing

Fill spray or mixing tank 1/2 full with water or carrier. Maintain continuous agitation and add Trilogy. Add other labeled spray materials and add balance of water. (Note: Add dry flowables, water dispersible granules, and liquids other than emulsifiable concentrate to the tank before Trilogy.) Avoid over-spraying to the point of excessive runoff. Do not allow diluted sprays to remain in the tank for more than 48 hours.

Before mixing in your spray tank, test physical compatibility by mixing all ingredients in a small container in proportional amounts. Avoid tank mixes with captan, sulfur, Bravo® or other chemically similar products as unpredictable results or leaf burn may occur. Growers should test combinations for phytotoxicity on a sample of plants prior to use.

Application Recommendations

Trilogy can be applied by ground application equipment in a minimum of 25 gallons of water per acre or aerial application in a minimum of 5 gallons of water per acre. Trilogy should be applied as a 1% spray solution for the control of labeled diseases or for the control of labeled mite species. Do not apply less than 25 gallons of diluted material per acre in ground application.

Trilogy should be diluted to 1% concentration. Use the following table to assist in determining the amount of Trilogy needed.

Total Volume of
Spray Mix
Trilogy Required for
1% Solution
125 gallons 5 quarts
100 gallons 4 quarts
75 gallons 3 quarts
50 gallons 2 quarts
25 gallons 1 quart

Apply sufficient volumes of this spray mix to provide thorough coverage of foliage. For example, in citrus apply 60 to 125 gallons of water containing 1% Trilogy per acre. For vegetable crops, apply 25 to 100 gallons of spray mix per acre.
