    Item # AVGR-OPTC2.5G-02 - View SDS

    Avenger® AG Optima is an excellent botanical alternative to synthetic, toxic herbicides when you need to use in areas where children and pets are present. It’s intended for both agricultural and non-agricultural use and has a more economical dilution ratio versus competitors.  Using a natural citrus oil base, this is a non-selective herbicide that kills a broad spectrum of weeds and unwanted grasses naturally and quickly. Its main ingredient is d-Limonene and it is for use in organic production around both food crop and non-crop areas. Always follow label directions.

    • Environment: Outdoors, Crops, Orchards & Vineyards, Nursery
    • Active Ingredients: d-Limonene (citrus oil)
    • Shelf Life: 2 years from manufacture date
    • Toxicity: No toxicity known
    • Certifications: EPA, USDA NOP
    • Storage: Store in original container

     How to Use: 

    Mix this product in clean water and apply to the foliage of vegetation to be controlled. Spray until weeds are thoroughly wet. Because the underside of the weed leaf may be more susceptible, side sprays are recommended.

    Environmental Conditions:

    Avenger® AG Optima is effective over a wide range of environmental conditions. Cool weather may slow the activity of the product. For best results, spray when ambient high temperatures are expected above 50°F and lows above freezing. On cooler days, spray during the warm part of the day. Allow heavy dew to evaporate prior to Avenger® AG Optima applications. Do not apply if windy conditions exist or rain is expected within 2 hours.

     Mixing of Avenger® AG Optima:

     Fill the spray tank ½ full with clean water. Add Avenger® AG Optima while agitating. Then fill remainder with water.

     Tank Mixing of Avenger® AG Optima:

     Fill the spray tank ½ full with clean water. Add any dry formulations and then liquid formulations to the tank. Add Avenger® AG Optima while agitating. Then fill remainder with water.


     Do NOT exceed 5 gallons of Avenger® AG Optima (20.4 lbs. d-limonene) per acre per application. Do NOT exceed a total of 16 gallons of Avenger® AG Optima (65.1 lbs. d-limonene; Table 1) per acre per year. Determine the final desired finished spray volume according to the appropriate dilution as describe in Table 1. Irrigation and Aerial

    Applications: Do not apply this product through any type of irrigation system or by aerial application.

     Spray Drift Management:

     Follow directions for minimizing spray drift. Do not allow the herbicide solution to contact desirable vegetation as small amounts can cause severe damage to crops and other desirable plants. AVOID CONTACT WITH CROP – Intentional or accidental contact (including drift) of Avenger® AG Optima with the crop may result in severe damage or loss of the crop.

     Application Rate:

    Four types of applications are described below: Broadcast, Banded, Spot and Pre-Harvest Desiccation. Mixing volumes for two dilution rates are found in Table 1. Apply Avenger® AG Optima at a 7-10% mixture depending on the size of the weeds. For smaller, young, actively growing weeds and grasses, apply the lower 7% mixture. For controlling larger, tough to kill weeds, use the higher 10% mixture. Use the lowest mixture whenever possible to control weeds and grass.

    • Broadcast Applications: Broadcast treatments are used for burndown of unwanted weeds and grass across a field or a plot or apply to burndown winter foliage. Apply Avenger® AG Optima at pre-emergence or at planting. Applications must be made before seedling emergence to avoid severe injury. Allow at least 2 days between application and transplanting. Spray until weeds and grass are thoroughly wet.
    • Banded Applications: Control or suppression of emerged weeds and grasses in row middles and between vines and trees. Apply Avenger® AG Optima at a 7-10% mixture depending on the size of the weeds. Only use the 10% mixture when absolutely necessary to control difficult weeds. Apply by directing spray between the rows and using hooded sprayers to prevent spray contact with crop plants. Keep hoods adjusted to ensure adequate contact with weeds and grass while shielding the crop from the herbicide. To minimize drift, do not use nozzles or nozzle configurations that produce fine droplets (mist).
    • Spot Applications: In cool situations or for tough to kill weeds, a more concentrated spray of d-limonene may be needed. In such situations, a 10% mixture of Avenger® AG Optima (1:10 mixture) may be used up to one (1) week before harvest (see Table 1).
    • Pre-Harvest Desiccation of Vegetable Vines: Apply Avenger® AG Optima at a 7 or 10% mixture to aid in the desiccation of vegetable vines prior to harvest operations. A second application may be necessary to obtain sufficient desiccation.
