Atrazine benefits

The benefits of the triazines in multiple cropping systems range from their application flexibility, effective weed control, soil residual activity, and crop selectivity to their important role in resistance management and conservation tillage. The triazines also have made a major impact on agricultural sustainability and crop yields, as evidenced by the use of atrazine, especially in com. [Pg.8]

The yield benefits of atrazine and other triazines vary by tillage type, and field studies have shown that the impact is higher under no-till than under conventional tillage systems (Carlson, 1998). [Pg.8]

A coordinated Atrazine Yield Check Program was launched throughout corn-growing areas to quantify atrazine s benefits. In the fall, representatives went to cornfields and picked ears from three random sections of both atrazine-treated... [Pg.39]

The triazine herbicides have revolutionized agricultural production of corn and more than 40 other crops. The yield increases, less labor-intensive production, and use for erosion control in conservation tillage are all benefits of the tri-azines, especially atrazine and simazine. Registered since the late 1950s, atrazine is still a mainstay of corn production and likely the most studied herbicide by regulatory agencies. [Pg.43]

Regulatory bodies in the United States, the European Union, Australia, and France, as well as the World Health Organization, have all given atrazine favorable safety reviews for continued registration. The safe use and resulting benefits of the triazines in worldwide agricultural production are critical as farmers continue to feed our growing population. [Pg.43]

The most recent USEPA (2003) assessment on the benefits of atrazine estimated an annual value of 1.58 billion in the United States for field com alone, based only on yield decreases and the increased cost of alternative herbicides. [Pg.154]

During 1995-1997, the information from past studies, almost 5000 field trials, new surveys of growers, and a weed control model developed by Dr. David Bridges (Bridges, 1998) were used to provide USEPA with estimates of the economic benefits of triazine and atrazine on all crops labeled with these products in the United States. A summary of the economic and biological models and some of the components are available (Bridges, 1998 Carlson, 1998). [Pg.158]

During late 1994, the United States Environmental Protection Agency (USEPA) published a public document (PD-1) relative to the use of triazine herbicides by American farmers. In doing so, they placed atrazine and simazine in Special Review. USEPA s PD-1 triggered a benefits study of unprecedented proportions on the following issues benefits of atrazine and simazine use economic and biological impact of the loss of these products feasibility and efficacy of alternatives environmental benefits associated with atrazine and simazine use best management practices and comparative performance of alternatives. [Pg.167]

Analysis approach - corn and sorghum A two-tiered approach was also used to characterize the benefits associated with uses of atrazine and simazine in corn and sorghum. First, a comparative analysis was made of product labels. The following parameters were considered in this review performance profiles, including efficacy, spectrum, and crop tolerance label comparisons physical and chemical characteristics of the product hazard profiles economic benefits and other relevant issues, such as use restrictions, etc. [Pg.167]

Comparative analyses and computer simulations revealed no true replacement(s) for triazine herbicides. Nonchemical alternatives were limited to cultivation and cultural practices, neither of which is very effective when used alone. The environmental costs of cultivation are simply too great, and repeated cultivation of the nation s com and sorghum crops is not feasible. Several chemical alternatives were considered, each revealing its own particular weakness (Bridges, 1998). Relative to atrazine use in com and sorghum, the following characteristics were identified as nearly irreplaceable benefits. [Pg.168]

Weather insensitivity Atrazine efficacy is relatively unaffected by weather. Since it is not particularly susceptible to photodegradation or to volatility, it can be applied under a variety of conditions and still be expected to deliver weed control benefits when rain occurs. The mode of action of atrazine in higher plants is such that the sensitivity of susceptible plants is only minimally affected by environmentally induced changes in plant growth, unlike many alternative herbicides that work well only in rapidly growing plants. [Pg.169]

So, should we still use atrazine All decisions involve tradeoffs, and the answer is rarely obvious. Does the benefit of increased food production outweigh possible health risks of a pesticide Do the beneficial effects of a new drug outweigh a potentially dangerous side effect in a small number of users Different people will have different opinions, but an honest evaluation of facts is surely the best way to start. At present, atrazine is approved for continued use in the United States because the EPA believes that the benefits of increased food production outweigh possible health risks. At the same time, though, the use of atrazine is being phased out in Europe. [Pg.25]
