Triplet Herbicide: Ounces per Gallon and Application Rates
Triplet herbicide, a popular selective herbicide used for post-emergence control of broadleaf weeds in corn and other crops, is a crucial tool for farmers and gardeners alike. Understanding the correct application rates, measured in ounces per gallon, is vital for effective weed control and preventing damage to your crops. This article delves into the intricacies of triplet herbicide application rates, ensuring you get the most out of this versatile herbicide.
Understanding Triplet Herbicide Concentration
Triplet herbicide is available in various concentrations, typically ranging from 2 to 4 pounds of active ingredient (ai) per gallon. The concentration you choose will depend on the severity of the weed infestation and the specific needs of your crops. Higher concentrations allow for lower application rates, saving you time and money.
Triplet Herbicide Concentrations and Active Ingredients
- Triplet 2: 2 pounds ai per gallon
- Triplet 3: 3 pounds ai per gallon
- Triplet 4: 4 pounds ai per gallon
Calculating Triplet Herbicide Application Rates
Application rates for triplet herbicide are typically expressed in ounces of active ingredient per acre (ai/acre). To calculate the application rate in ounces per gallon, you'll need to know the concentration of your herbicide and the size of the area you're treating. Here's a simple formula to help you calculate the application rate:

Application Rate (oz/gal) = (Application Rate (oz/acre) / Concentration (lb/gal)) * 128
Example: Calculating Application Rate for Triplet 3
Let's say you're using Triplet 3 (3 lb ai/gal) and want to apply 8 oz ai/acre to your field. First, convert the application rate to pounds:
8 oz ai/acre * (1 lb / 16 oz) = 0.5 lb ai/acre

Now, plug this value into the formula:
Application Rate (oz/gal) = (0.5 lb ai/acre / 3 lb ai/gal) * 128 = 21.33 oz/gal
Recommended Triplet Herbicide Application Rates
The following table provides recommended application rates for triplet herbicide, based on the concentration and the specific weeds you're targeting. Always consult the product label for the most accurate and up-to-date information.
| Concentration (lb ai/gal) | Application Rate (oz/gal) | Target Weeds |
|---|---|---|
| 2 | 16-32 | Velvetleaf, Lambsquarters, Pigweed, etc. |
| 3 | 12-24 | Velvetleaf, Lambsquarters, Pigweed, etc. |
| 4 | 9-18 | Velvetleaf, Lambsquarters, Pigweed, etc. |
Tips for Successful Triplet Herbicide Application
To ensure the best results from your triplet herbicide application, consider the following tips:
- Apply herbicide when weeds are actively growing and have fully emerged.
- Use a spray volume of at least 15-20 gallons per acre for adequate coverage.
- Calibrate your spray equipment to ensure accurate application rates.
- Make applications when wind speed is less than 3 mph to prevent drift.
- Rotate triplet herbicide with other modes of action to prevent resistance.
By understanding and following the application rates and tips outlined in this article, you can effectively control weeds and maximize the productivity of your crops with triplet herbicide.
