Atrazine is a common herbicide that acts as both a pre-emergent (kills weeds before they sprout) and post-emergent (kills mature weeds) weed control. Not only does Atrazine kill most weeds, but it also kills most grasses. This is great for controlling pest grasses but is harmful to many species of turfgrasses *Atrazine Application Rates *Atrazine applications for corn are restricted to a maximum of 2.5 pounds active ingredient per acre (lb. ai/A) per calendar year. In addition, there is a per-application maximum of no more than 1.6 or 2 lb. ai/A depending on soil erodibility (as defined by NRCS) and the amount of crop residue cover Farmers use atrazine to control weeds on well over half of the country's corn acreage, about two-thirds of sorghum acreage and 90 percent of its sugar cane.

Although atrazine can be used alone, it is more commonly used in combination with other herbicides;and applying atrazine postemergence allows you to reduce the total amount applied (because it reaches the foliage immediately). Consider other farm operations that must occur during the same time to determine if you can make a timely postemergence application. Atrazine applied preemergence to unprotected soil is vulnerable to escaping the fi eld in runoff if rain occurs shortly thereafter Atrazine is used both as a pre-emergent and post-emergent herbicide to control weeds. As a pre-emergent, it prevents germination of weedy broadleaf and cool-season grass seeds, and as a post-emergent it kills actively growing annual cool-season weeds

Atrazine is one of the most widely used herbicides in the U.S., and is found in 94% of U.S drinking water tested by the USDA — more often than any other pesticide. An estimated 7 million people were exposed to atrazine in their drinking water between 1998 and 2003. The highest levels of contamination are in the Midwest where it is widely used. Atrazine is the most commonly used s-triazine herbicide in agriculture. It is rapidly absorbed by plant roots and, to a lesser extent, by plant shoots (Esser and Marco, 1975). Once in the plant it translocates readily (apoplastically) in the xylem and cell walls A popular herbicide is showing up in drinking water supplies, threatening its future use by Indiana farmers. Producers who use weed control products with the active ingredient atrazine need to be.

As late as 2002, it was estimated that atrazine was the most commonly used herbicide in the world with applications in 80 countries Atrazine is an herbicide used to prevent and kill weeds. It also acts as an endocrine disruptor in humans that causes all sorts of deleterious effects. It's been over a decade now (2007) since the EPA has recognized this fact Unlike many other herbicides, atrazine has a wide spectrum of uses, applications and utility. Farmers use atrazine to control weeds on well over half of the country's corn acreage, about two-thirds of sorghum acreage and 90% of its sugar cane, Sisung says.

Atrazine is typically applied as a pre -emergent so that it is taken up b Atrazine is a widely used herbicide that can be applied before and after planting to control broadleaf and grassy weeds. Atrazine is part of the triazine chemical class, which includes simazine and propazine due to their common mechanism of toxicity. It is primarily used in agriculture (with the greatest use on corn, sorghum, and sugarcane) Atrazine is a widely used herbicide, especially in corn, to control weeds at planting time. Atrazine affects the photosynthetic mechanism in plants, but its molecular structure is an endocrine disruptor, inasmuch as it resembles the growth hormones of other organisms, including frogs and potentially humans Atrazine is a common agricultural herbicide with endocrine disruptor activity. There is evidence that it interferes with reproduction and development, and may cause cancer.

Herbicides (Triazine Family) • Atrazine provides excellent control of most broadleaf weeds and is commonly used as a supplement to one of the grass herbicides discussed. Although atrazine is usually applied to the soil surface immediately after seeding, it can also be soil incorporated if tank mixed with a preplant incorporated grass herbicide Atrazine is also of concern but not as much as mesotrione and isoxaflutole. Atrazine is less water-soluble (30-300 ppm); however, it still moves with water (e.g., rainfall). Atrazine is prone to enhanced microbial degradation, especially in soils where it has been used in the past (Kurtz et al., 2010) included Atrazine controlled 95-100 percent of all broadleaf weeds. The addition of a crop oil concentrate increased the activity of Atrazine on grasses when compared to Atrazine alone. Herbicide combinations of Dual, Ramrod, and Prowl with 2,4-D or atrazine did not significantly improve weed control over Atrazine applied alone in 1993. I Apply herbicides in ½-1 gallon of water per 1,000 square feet (approximately 20-40 gallons per acre).
