ABSTRACT:
Glyphosate and Roundup Ready® crops are popular because they provide consistent, broad spectrum weed control with minimal risk of crop injury. On occasion, however, growers experience poor weed control with glyphosate, generally because of application or weather-related factors. This publication examines the factors that affect glyphosate performance and offers management strategies to minimize fluctuations in its effectiveness. FULL TEXT

ABSTRACT:
This memorandum transmits an updated Screening Level Usage Analysis (SLUA) report for the glyphosate case (previously completed in 2007). The usage data in the updated SLUA (2015) are an amalgamation of USDA/NASS and Private Pesticide Market Research data from 2005 to 2014. The new SLUA (2015) shows a decrease in usage, in terms of pounds a.i. and/or percent crop treated on apples, apricots, artichokes, avocados, broccoli, caneberries, cauliflower, grapefruit, garlic, nectarines, oranges, pasture, peaches, pears, pecans, and tangelos. The usage data did not change for cantaloupes, carrots, celery, lemons, oats, green beans, and pumpkins. The new SLUA (2015) shows an increase in usage, in terms of pounds a.i. and/or percent crop treated on the remainder of the SLUA crops. FULL TEXT

ABSTRACT:
SUMMARY: This document establishes tolerances and food and feed additive regulations for the combined residues of the herbicide glyphosate (N-(phosphonomethyl)glycine) and its metabolite aminomethyl phosphonic acid. The specific proposals are: an amended tolerance in or on the raw agricultural commodities (RACs) soybeans from 6 parts per million (ppm) to 20 ppm; a tolerance on soybean straw at 20 ppm; a food additive regulation proposing increases in tolerances for the processed human food instant tea from 4.0 ppm to 7.0 ppm; a feed additive regulation for citrus molasses at 1 ppm; and amended feed additive tolerances for dried citrus pulp from 0.4 ppm to 1 ppm and soybean hulls from 20 ppm to 100 ppm. These regulations were requested by the Monsanto Co. and would establish the maximum permissible residues of the herbicide in or on these RACs, this processed human food, and these animal feed commodities.

ABSTRACT:
Tolerances are established for residues of glyphosate, including its metabolites and degradates, in or on the commodities listed below resulting from the application of glyphosate, the isopropylamine salt of glyphosate, the ethanolamine salt of glyphosate, the dimethylamine salt of glyphosate, the ammonium salt of glyphosate, and the potassium salt of glyphosate. Compliance with the following tolerance levels is to be determined by measuring only glyphosate (N-(phosphonomethyl)glycine).

ABSTRACT:
In the present study glyphosate residues were tested in urine and different organs of dairy cows as well as in urine of hares, rabbits and humans using ELISA and Gas Chromatography-Mass Spectroscopy (GC-MS). The correlation coefficients between ELISA and GC-MS were 0.96, 0.87, 0.97and 0.96 for cattle, human, and rabbit urine and organs, respectively. The recovery rate of glyphosate in spiked meat using ELISA was 91%. Glyphosate excretion in German
dairy cows was significantly lower than Danish cows. Cows kept in genetically modified free area had significantly lower glyphosate concentrations in urine than conventional husbandry cows. Also glyphosate was detected in different organs of slaughtered cows as intestine, liver, muscles, spleen and kidney. Fattening rabbits showed significantly higher glyphosate residues in urine than hares. Moreover, glyphosate was significantly higher in urine of humans with
conventional feeding. Furthermore, chronically ill humans showed significantly higher glyphosate residues in urine than healthy population. The presence of glyphosate residues in both humans and animals could haul the entire population towards numerous health hazards, studying the impact of glyphosate residues on health is warranted and the global regulations for the use of glyphosate may have to be re-evaluated.

ABSTRACT:
Glyphosate is a broad-spectrum herbicide that is one of the most frequently applied pesticides in the world. Although there has been little consistent evidence of genotoxicity or carcinogenicity from in vitro and animal studies, a few epidemiologic reports have indicated potential health effects of glyphosate. We evaluated associations between glyphosate exposure and cancer incidence in the Agricultural Health Study (AHS), a prospective cohort study of 57,311 licensed pesticide applicators in Iowa and North Carolina. Detailed information on pesticide use and other factors was obtained from a self-administered questionnaire completed at time of enrollment (1993–1997). Among private and commercial applicators, 75.5% reported having ever used glyphosate, of which > 97% were men. In this analysis, glyphosate exposure was defined as a) ever personally mixed or applied products containing glyphosate; b) cumulative lifetime days of use, or “cumulative exposure days” (years of use × days/year); and c) intensity-weighted cumulative exposure days (years of use × days/year × estimated intensity level). Poisson regression was used to estimate exposure–response relations between glyphosate and incidence of all cancers combined and 12 relatively common cancer subtypes. Glyphosate exposure was not associated with cancer incidence overall or with most of the cancer subtypes we studied. There was a suggested association with multiple myeloma incidence that should be followed up as more cases occur in the AHS. Given the widespread use of glyphosate, future analyses of the AHS will allow further examination of long-term health effects, including less common cancers. FULL TEXT
