DIRECTIONS FOR USE

Mixing Procedures

Prepare no more spray mixture than is needed for the immediate operation. Thoroughly clean spray equipment before using this. Agitation is necessary for proper dispersal of the product. Maintain agitation throughout the spraying operation. Do not let the spray mixture stand overnight in the spray tank. Flush the spray equipment thoroughly following each use and apply the rinsate to a previously treated area.

TRIGO Alone:

Add 1/2 of the required water to the mix tank. With the agitator running, add the prescribed dose of TRIGO to the tank. Continue agitation while adding the remainder of the water. Begin application of the solution after TRIGO has completely dispersed into the mix water. Maintain agitation until all of the mixtures has been applied.

TRIGO + Tank Mixtures:

Add 1/2 of the required amount of water to the tank mix. Start the agitation running before adding TRIGO and any tank mix partner(s). In general, tank mix partners must be added in this order: (1) products packaged in water-soluble packaging, wettable powders, wettable granules (such as TRIGO), (2) liquid flowable, liquids; and (3) emulsifiable concentrates. Always allow each tank mix partner to become fully dispersed before adding the next product. Provide sufficient agitation while adding the remainder of the water. Maintain agitation until all of the mixtures has been applied.

If using TRIGO in a tank mixture, observe all restrictions, directions for use, crop/sites, use rates, dilution ratios, precautions and limitations that appear on the tank mix product label. Do not exceed labeled dosage rate, and the most restrictive label precautions and limitations must be followed. This product must not be mixed with any product that prohibits such mixing. Tank mixtures or other applications of products referenced on this label are permitted only in those states in which the referenced products and uses are registered.

TRIGO is compatible with most insecticide, fungicide, and foliar nutrient products. However, the compatibility of TRIGO with tank mix partners must be tested before use. To determine biological compatibility with other products, mix the products in the desired proportions, spray on target plants and observe for phytotoxicity seven days after the application.

Use with additives:

Use of spray additives is not required. Any spray additive must be evaluated prior to use. Do not use in conjunction with organosilicate-based products or plant injury may occur. Label directions are based on data with no additives. Chemigation: Do not apply this product through any type of irrigation system.

Aerial Application: Do not apply by aerial application.

Resistance Management: TRIGO contains the strobilurin class of chemistry, which exhibits no known cross-resistance to other chemical classes including sterol inhibitors, dicarboximides, benzimidazoles, anilinopyrimidines or phenylamides. However, certain fungal pathogens are known to develop resistance to products used repeatedly. Because resistance development cannot be predicted, the use of this product must conform to resistance management strategies. Such strategies may include rotating and/or tank mixing with products having different modes of action; or limiting the total number of applications per season. Bayer CropScience LP encourages responsible product stewardship to ensure effective long-term control of the fungal diseases on this label. See specific directions in the ornamentals section.

ORNAMENTAL DISEASE CONTROL

TRIGO is a broad-spectrum systemic fungicide for the control of listed foliar and stem diseases of ornamentals including flowers, foliage plants, shrubs, shade trees and non-bearing fruit trees grown in nurseries, garden centers, and greenhouses.

Garden Center and Nursery Applications

Foliar Diseases:

TRIGO will control foliar diseases of ornamental plants when applied as a foliar spray to the plant species listed on this label. Apply 3 to 9 oz TRIGO per 100 gallons of spray solution. Apply as a full-coverage spray to the point of drip and repeat at 14 to 28-day intervals until the threat of disease is over. Begin applications when conditions are favorable for disease development and continue until the threat of disease is over. Use higher rates or shorter intervals under high disease pressure. Do not exceed a maximum of 207 oz of TRIGO per acre per year (4.76 oz/1000 sq ft). Do not exceed a volume of 530 gallons of spray mix per acre per application at the highest application rate of 9 oz/100 gal.

Greenhouse Applications

Except as noted for specific diseases, mix 1.2 to 2.4 ounces of TRIGO in 100 gallons of water and apply as a full coverage foliage spray to the point of drip. Do not exceed a volume of 530 gallons of spray mix per acre at the highest dose rate of 9 oz/100 gal.

• Winter Use –1.2 oz of TRIGO
• Summer Use – 2.4 oz of TRIGO

Mix the specified amount of TRIGO in 100 gallons of water and apply in a spray application to the point of drip. Intervals between applications must be no shorter than 30 days to avoid flower stalk length reduction. Excessive rates or applications may result in a shortening of the flower stalk.

Maximum Use Rates in Ornamentals

For ornamental plants do not exceed a maximum of 207 oz of TRIGO per acre per year (4.76 oz/1000 sq ft). Do not exceed a volume of 530 gallons of spray mix per acre per application at the highest application rate of 9 oz/100 gal.

Resistance Management for Ornamentals

TRIGO contains a site-specific fungicide belonging to the strobilurin class of chemistry. Fungal pathogens are known to develop resistance to fungicides with a specific mode of action. When site-specific fungicides are used without a clear resistance management strategy, resistance development may be rapid, particularly with greenhouse use.

TRIGO exhibits cross-resistance to other strobilurins and fungicides within the Strobilurin Type Action and Resistance group (STAR compounds), but there is no known cross-resistance to fungicides of other classes including sterol inhibitors, dicarboximides, benzimidazoles, anilinopyrimidines, phenylpyrroles or phenylamides. Many plant pathogens have a history of fungicide resistance development. To minimize the risk of resistance development to TRIGO, the following practices are prescribed:

1. Use TRIGO preventively.
2. For Leaf Spots and diseases other than Powdery Mildew, Downy Mildew:

• Use no more than two (2) applications of TRIGO before rotating to another effective product that is not in the strobilurin class of chemistry for two (2) applications before rotating back to TRIGO. OR
• Rotate to another fungicide of nonstrobilurin chemistry after each TRIGO application.

       3. For Powdery Mildew, Downy Mildew:

• Between each TRIGO application, make two (2) applications of a fungicide of nonstrobilurin chemistry before rotating back to TRIGO.

           OR

• Rotate to another fungicide of nonstrobilurin chemistry after each TRIGO application. 

        4. Make no more than four (4) foliar applications of TRIGO per season for each at-risk pathogen.
