“…The percentage of herbicide-treated acreage for spring and durum wheat is larger than for winter wheat, which is a better competitor with weeds (Lin et al 1995). For counties with a large winter wheat acreage, I applied a correction factor to the winter wheat acreage before combining it with spring and durum wheat acreage to obtain a value for total wheat acreage.…”

In this ecologic study I examined ischemic heart disease (IHD) and diabetes mortality in rural agricultural counties of Minnesota, Montana, North Dakota, and South Dakota, in association with environmental exposure to chlorophenoxy herbicides, using wheat acreage as a surrogate exposure. I collected data on agricultural land use and 1979–1998 mortality from the U.S. Department of Agriculture and the Centers for Disease Control and Prevention websites, respectively. Counties were grouped based on percentage of land area dedicated to wheat farming. Poisson relative risks (RR) and 95% confidence intervals (CIs), comparing high- and medium- with low-wheat counties, were obtained for IHD, the subcategories acute myocardial infarction (AMI) and coronary atherosclerosis (CAS), and diabetes, adjusting for sex, age, mortality cohort, and poverty index. Mortality from IHD was modestly increased (RR = 1.08; 95% CI, 1.04–1.12). Analyses of its two major forms were more revealing. Compared with low-wheat counties, mortality in high-wheat counties from AMI increased (RR = 1.20; 95% CI, 1.14–1.26), and mortality from CAS decreased (RR = 0.89; 95% CI, 0.83–0.96). Mortality from AMI was more pronounced for those < 65 years of age (RR = 1.31; 95% CI 1.22–1.39). Mortality from type 2 diabetes increased (RR = 1.16; 95% CI, 1.08–1.24). These results suggest that the underlying cause of mortality from AMI and type 2 diabetes increased and the underlying cause of mortality from CAS decreased in counties where a large proportion of the land area is dedicated to spring and durum wheat farming. Firm conclusions on causal inference cannot be reached until more definitive studies have been conducted.

“…Herbicide use increases in U.S. corn production systems when switching from conventional tillage with the moldboard plow to zero tillage (Lin et al, 1995), but in the full C cycle analysis for U.S. farming systems, the increase in herbicide use was offset by far by the reduction in fossil fuel for tillage operations (West and Marland, 2002). Based on U.S. average crop inputs, zero tillage emitted less CO 2 from agricultural operations than did conventional tillage, with 137 and 168 kg C ha −1 per year respectively, including the C emissions associated with the manufacture, transportation, and application of fertilizers, agricultural lime, and seeds (West and Marland, 2002).…”

“…Moreover, data on the application rates were needed to calculate the dependent variable (price per application per acre). The selection of the herbicide attributes considered in the study is based on previous literature (Beach and Carlson 1993, Fernadez-Cornezo 2009, Lin et al 1995, in conjunction with suggestions from University of Kentucky weed specialists 7 .…”

“…Although extensive research has been done to analyze the effect of prices, production practices and government programs on farm chemical usage (Lin et al, 1995) the literature examining herbicide pricing is relatively small mainly because of data limitations, especially after USDA-NASS has reduced the amount of data it collects. Beach and Carlson (1993) illustrated that it is possible using hedonic analysis to estimate implicit prices for herbicide attributes.…”

Herbicides account for approximately 2.2% of total farm expenses and are applied to more than 80% of farmland in the USA. The widespread adoption of herbicides contributed to the increased and relatively cheaper productivity of modern intensively managed agricultural systems in developed countries. The present study uses a hedonic framework to analyze the effect of selected attributes on the price of corn and soybean herbicides. Two different empirical models were estimated separately for the two crops. The data include information on 51 herbicides, 27 for corn and 24 for soybean crops used in Kentucky. Findings indicate that efficacy against weeds and crop response (illustrates the potential of an herbicide to injure a crop) of herbicides are significant determinants of their prices. Moreover, some of the environmental statements have an effect on herbicide prices. The study confirms the importance of explicitly including information about herbicides active ingredients and their impacts on plants' physiological cycle as it improved the model fit for corn herbicides and provided results in line with the a-priori hypothesis.
