What Is Atrazine and How Does It Control Weeds?

Atrazine is a synthetic herbicide belonging to the triazine chemical class. It works by selectively targeting and disabling photosynthesis in susceptible plant species, particularly annual broadleaf weeds and certain grasses. Once absorbed through the foliage or root system, Atrazine inhibits the electron transport in the chloroplasts, which blocks the plant’s ability to produce essential energy—eventually leading to starvation and death of the weed.

This herbicidal mode of action makes Atrazine an effective pre-emergent solution—applied to the soil before weed seeds germinate—and also useful as a post-emergent herbicide when sprayed directly on young weeds. Its systemic absorption ensures long-lasting residual control, especially in crops like corn, sorghum, and sugarcane, as well as in well-established turf areas.

Unlike non-selective herbicides that damage all plants, Atrazine is designed for selective control, allowing the crop or turf to thrive while suppressing competing weeds. This makes it ideal for integrated weed management (IWM) programs where maximizing yield and minimizing herbicide resistance are critical.

Atrazine Formulations and Concentration Options

Atrazine herbicide is available in a range of formulation types and concentrations to accommodate diverse agricultural and turf management needs. Each formulation offers specific advantages in terms of solubility, application method, and field stability, allowing you to select the most effective solution for your operational environment.

Common Atrazine Formulations:

• Atrazine 50% SC (Suspension Concentrate):
  Offers excellent dispersion in water, ideal for foliar application via sprayers in field crops such as corn and sugarcane.
• Atrazine 50% WP (Wettable Powder):
  A cost-effective option for large-scale weed control programs; requires thorough mixing but provides strong residual control.
• Atrazine 80% WP / 80% WDG (Water-Dispersible Granules):
  Designed for ease of transport, handling, and application, these high-content dry formulations are preferred in markets requiring longer shelf life and minimal storage risk.

Customized Mixed Formulations:

To expand weed spectrum control and offer synergistic effects, Atrazine is often formulated with complementary herbicidal active ingredients:

• Atrazine 50% + Mesotrione 5% SC – Enhanced efficacy against resistant broadleaf weeds.
• Atrazine 14% + Propisochlor 26% SE – Provides longer-lasting residual control, especially in row crops.
• Atrazine 84% + Nicosulfuron 8% WDG – Excellent for post-emergent applications in maize and cereals.

These mixtures not only reduce application frequency but also help mitigate resistance development by combining different modes of action.

Target Crops and Weed Spectrum of Atrazine

Atrazine herbicide is trusted across both agricultural and turf management sectors due to its broad-spectrum efficacy against annual broadleaf and grassy weeds. Its mode of action—photosynthesis inhibition—makes it particularly effective for early-season weed suppression, helping you achieve optimal yield potential and maintain a clean field throughout the growing cycle.

Applicable Crops:

Atrazine is commonly applied to the following crops and managed areas:

• Corn (Maize): Highly effective pre- and post-emergent control of key weeds including pigweed, foxtail, and lambsquarters. Often used alone or in tank mixes to enhance spectrum control.
• Sorghum: Provides excellent protection against annual grasses and broadleaf weeds during early development.
• Sugarcane: Helps maintain weed-free conditions during the establishment phase, especially targeting crabgrass and smartweed.
• Turf & Lawns: Ideal for St. Augustine grass, centipedegrass, and other tolerant turf species. Controls tough lawn weeds such as spurge, dandelions, and chickweed.
• Non-Crop Areas: Used in roadside maintenance, fence lines, and industrial zones to eliminate persistent weed growth like foxtail and marestail.

Target Weeds Controlled:

Atrazine effectively controls many common and problematic weeds, including:

• Broadleaf Weeds: Spurge, pigweed, chickweed, dandelion, lambsquarters, marestail, smartweed
• Annual Grasses: Foxtail, crabgrass, barnyard grass, wild oats

For optimal results, Atrazine should be applied when target weeds are young and actively growing. It is especially effective in combination with complementary herbicides for managing herbicide-resistant or hard-to-kill species.

Application Methods & Best Practices

How to Use Atrazine Herbicide Effectively

To ensure optimal weed control and crop safety, Atrazine must be applied with proper timing, dosage, and equipment suited to your specific crop and environmental conditions. Below are best practices developed from field-proven applications:

Application Timing:

• Pre-Emergent Use: Apply Atrazine before weed emergence or at early seedling stages to suppress germination and establishment. Especially effective in corn, sorghum, and lawns.
• Post-Emergent Use: Apply when weeds are no more than 10 cm tall. Ensure crops such as corn are already well-established (above 30 cm in height) to avoid crop injury.

Spray Volume & Coverage:

• Use a ground sprayer with uniform nozzle distribution.
• Dilute Atrazine using 750–1000 L of water per hectare to achieve even soil coverage.
• Avoid overlapping or skipping rows during application.

Incorporation into Soil:

• In dry conditions (7–15 days post-application), a shallow rotary cultivation can help incorporate the herbicide into the topsoil, improving activation and performance.
