Tools Needed

How to Use
- Step 1: Determine how much Gemini 3.7 SC Herbicide to use by measuring the square footage of the treatment area. To do this, measure the length and width of the treatment area in feet then multiply them together (length X width = square footage). For acreage, take the square footage and divide it by one acre (square footage / 43,560 sq. ft. = acres). Depending on the turf type, you will use between 18 to 87 fl. oz. of Gemini 3.7 SC Herbicide in 0.5 gallons of water per 1,000 sq. ft. or 0.41 to 2.0 fl. oz. of product in 20 gallons of water per acre. For container, field grown and landscape ornamental plantings, Christmas tree farms, and non-crop areas, apply 0.9 to 2.0 fl. oz. of product in 0.5 gallons of water per 1,000 sq. ft. or 38 to 87 fl. oz. of product in 20 gallons of water per acre. Refer to the label for specific application rates.
- Step 2: Fill the spray tank with half the amount of water, add measured amount of Gemini 3.7 SC Herbicide, then pour in the remaining half of water. Maintaining vigorous agitation in the spray tank until solution is well-mixed and continue doing so throughout the application to ensure a well-mixed spray suspension.
- Step 3: Spray the Gemini 3.7 SC Herbicide mixture to soil free of weeds, clods, and debris. After application, irrigate treated areas with 0.5 inches of water or rainfall (as long as its its within 14 days). Apply this product to newly-transplanted and established ornamentals as an over-the-top spray.
Where to Use
Gemini 3.7 SC Herbicide may be applied in established turfgrasses (excluding golf course putting greens), lawns and ornamentals, conifer and hardwood seedling nurseries, non-crop areas including rights-of way for transportation systems and utilities (including roadways, roadsides, railways and equipment yards), facilities including substations, tank farms, pumping stations, parking and storage areas, and ungrazed fence rows, and Christmas tree farms.
This product cannot be applied to golf course putting greens.
When to Use
Apply Gemini 3.7 SC Herbicide when weeds are not present and foliage is well-established and rooted. Do not apply to turf stressed by conditions such as drought, low fertility, or pest damage.
Do not apply to bedding plants or areas where bedding plants will be planted or transplanted within one year after application. Do not apply after emergence of ornamental bulbs.

| Keith's Pro Tips | "Although Gemini 3.7 SC Herbicide contains a large number of ornamental species, it is not possible to include all of the ornamental plants that may be encountered in a nursery or landscape setting. On a plant species not listed on this label the user may determine the suitability of such use by treating a small area or number of these plants at a specified rate. Prior to treatment of larger areas, the treated area or plants should be observed for any sign of herbicidal injury during the 30 to 60 days of typical growing conditions." |
| Product Drawbacks | Applications of Gemini 3.7 SC Herbicide over the top of plants with newly forming buds may cause injury. Possible plant injury may be avoided by application as a directed spray to the soil surface beneath ornamental plants. |
