Prodiamine is a popular pre-emergent herbicide used to control a wide range of weeds in lawns, landscapes, and other areas. When it comes to applying prodiamine granular, it's essential to get the application rate right to ensure effective weed control while minimizing the risk of environmental harm or damage to desirable plants. In this article, we'll delve into the world of prodiamine granular application rates, exploring the factors that influence the rate, the benefits of using the correct rate, and providing practical guidance on how to apply prodiamine granular effectively.
Understanding Prodiamine Granular Application Rates
The application rate of prodiamine granular refers to the amount of product applied per unit area, usually expressed in pounds per acre (lb/acre) or pounds per thousand square feet (lb/1000 sq ft). The correct application rate is crucial to ensure that the herbicide is effective against target weeds while minimizing the risk of overspray or drift onto non-target areas.
Factors Influencing Prodiamine Granular Application Rates
Several factors can influence the application rate of prodiamine granular, including:
- Weed species: Different weed species have varying levels of susceptibility to prodiamine. Some weeds, like annual bluegrass and crabgrass, may require higher application rates, while others, like broadleaf weeds, may require lower rates.
- Soil type: Soil texture, pH, and organic matter content can affect the movement and availability of prodiamine in the soil. For example, prodiamine may move more quickly through sandy soils, requiring lower application rates, while clay soils may require higher rates.
- Climate: Weather conditions, such as temperature, rainfall, and humidity, can impact the efficacy and longevity of prodiamine. In areas with high temperatures and rainfall, higher application rates may be necessary to maintain effective weed control.
- Application timing: The timing of prodiamine application can also impact the application rate. Applying prodiamine too early or too late in the growing season may require adjustments to the application rate.
Benefits of Using the Correct Prodiamine Granular Application Rate
Using the correct prodiamine granular application rate can provide several benefits, including:
- Effective weed control: The correct application rate ensures that the herbicide is present in sufficient quantities to control target weeds.
- Minimized environmental risk: Using the correct application rate reduces the risk of overspray or drift onto non-target areas, minimizing the potential for environmental harm.
- Cost savings: Applying the correct amount of prodiamine granular can help reduce waste and minimize the need for repeat applications.
- Optimized turf health: The correct application rate can help promote healthy turf growth by reducing weed competition and minimizing the risk of herbicide damage to desirable plants.
How to Apply Prodiamine Granular Effectively
To apply prodiamine granular effectively, follow these steps:
- Read the label: Carefully read the product label to understand the recommended application rates, timing, and any specific use restrictions.
- Calibrate your spreader: Ensure that your spreader is calibrated to deliver the correct amount of prodiamine granular per unit area.
- Choose the right application timing: Apply prodiamine granular at the recommended time, usually in early spring or fall, depending on the target weed species and climate.
- Follow integrated pest management (IPM) practices: Use prodiamine granular as part of an IPM strategy that includes cultural, mechanical, and biological controls to manage weeds and promote healthy turf growth.
Common Prodiamine Granular Application Rates
The following are some common prodiamine granular application rates:
- Pre-emergent application rates: 1.5-2.5 lb/acre (1.5-2.5 lb/1000 sq ft) for control of annual bluegrass, crabgrass, and other annual weeds.
- Post-emergent application rates: 0.5-1.5 lb/acre (0.5-1.5 lb/1000 sq ft) for control of broadleaf weeds and other perennial weeds.

Frequently Asked Questions
What is the recommended application rate for prodiamine granular?
+The recommended application rate for prodiamine granular varies depending on the target weed species, soil type, and climate. Typically, the application rate ranges from 1.5-2.5 lb/acre (1.5-2.5 lb/1000 sq ft) for pre-emergent applications and 0.5-1.5 lb/acre (0.5-1.5 lb/1000 sq ft) for post-emergent applications.
How often should I apply prodiamine granular?
+The frequency of prodiamine granular applications depends on the target weed species, soil type, and climate. Typically, prodiamine granular is applied once in the early spring or fall, depending on the target weed species and climate.
Can I use prodiamine granular on all types of turf?
+No, prodiamine granular is not suitable for all types of turf. It is recommended for use on cool-season and warm-season turfgrasses, but not on tropical or subtropical turfgrasses.
