Crop Residue and Accumulation Studies

We are experts in crop residue, dislodgeable foliar residue (DFR) and accumulation studies in North America. All of our crop residue and DFR studies have covered a wide range of agrochemicals, application methods, sampling techniques, crops (including turf, sugar cane, row crops, small grains, alfalfa, citrus and pome fruits) and geographic areas. Accumulation studies, such as those for nontarget organisms and irrigated crops, have been combined with aquatic dissipation studies to further enhance our knowledge.

Our Reach

Waterborne has developed a diverse network of highly capable field operators, which allows us to place crop residue studies within all 13-crop regions identified by the US Environmental Protection Agency. In Central and South America, our personnel have consulted on several important tolerance studies and influenced positive changes.

Crop residue, DFR and accumulation study types offered include:

  • Magnitude of residue (MOR)
  • Raw agricultural commodities
  • Process commodities
  • Import tolerance
  • Dislodgeable foliar residue (DFR)
  • Accumulation studies

Agrochemical residue accumulation studies offered by us include:

  • Irrigated crop
  • Field rotational crop
  • Aquatic nontarget organism

Pollinator Studies

The decline of honeybees and other pollinators in recent years has become a serious environmental concern—which also threatens the production of many important crops. Pesticide use has been identified as one potential contributing factor to these declines along with other factors, such as habitat loss. This has led to increasing calls for research and programs designed to preserve and increase the availability of all pollinators. Our pollinator studies are tackling this emerging issue head on, including the investigation of the potential impact of pesticides and integrated pest management (IPM) studies.

Environmental Fate and Transport Studies

In response to regulatory concerns, we conduct field studies to determine the carry-over of high-risk chemicals and their metabolites on pollinator food sources. The purpose of these studies is to determine the amount of pesticide, if any, in pollen and nectar of selected crops after foliar applications at the maximum label-use rate prior to bloom. Potential residue carry-over and subsequent uptake are investigated by repeating the study a second crop season using the same test sites as in the first year of the study. We study protocol design, field work and laboratory analysis.

Field Margin Planting Studies

Field margin planting studies examine best practices for enhancing native bee populations and other pollinators by establishing habitat on agricultural field margins or other areas of low productivity. They use appropriate seed mixtures of wildflowers and other native plants for a particular region and practices for establishing pollinator strips that can be transferred to commercial growers. As part of the field margin studies, Waterborne establishes and maintains the test plots, monitors the results of establishment and makes recommendations for better results.

IPM studies such as these can demonstrate that biodiversity conservation and conventional agricultural food production can be integrated, resulting in sustainable approaches to crop production.
