A mycotoxin produced by Aspergillus fungi, which grow whenever conditions are favorable (high moisture and temperature). Occurs in many diverse sources, ranging from major cereal crops to peanut butter, nuts and spices. Aflatoxins are genotoxic and among the most carcinogenic substances known. The main target organ in humans is the liver, but the risk of developing gallbladder cancer is also increased.

Land used for agriculture to grow food, animal feed, biofuel, etc.

The variety of species or life forms within any given area or region. These life forms include animals, plants, and all forms of organisms that serves a role in the health of the ecosystem.

Simple trenches filled with wood chips that filter water running from drain tile on farms. Their use helps reduce nitrate runoff into nearby waterways.

Small strips of land kept in permanent vegetation, located between primary crops, for the purpose of intercepting pollutants, slowing erosion and managing environmental concerns. These strips often also provide habitat for native wildlife and pollinators.

Plant material that remains after harvest. Can include stalks, leaves, and roots.

Qualitative and quantitative processes used to enhance productivity and business gain. In agriculture, analytics help farmers become more efficient with their resources, more precise with the timing and rate of inputs, and reduces impact on the environment in the process.

Compilation of all study reports and accompanying documents necessary to register an active substance or a plant protection product.

Designed to support precise approaches to nutrient management, grid sampling is the practice of taking multiple samples of soil per acre. Traditional soil sampling densities were 1 or 2 samples for every 3 or 4 acres. Grid sampling calls for as many as 42 samples per acre which are mapped and flagged throughout the field digitally, leading to an improved understanding of variability in soil nutrient needs on across the field.

Half maximal effective rate (ER50) refers to the rate of a substance which induces a response halfway between the baseline and maximum after a specified exposure time, i.e. the rate at which 50% of the maximal effect is observed.

Living genetic resources such as seeds or plant tissues that are maintained for the purpose of plant breeding, preservation, and other research uses.

Hybrid seeds are created using traditional breeding methods where two different but compatible plants are crossbred to create a new plant — also known as a hybrid. An example of this is the Honeycrisp apple. Developed through the University of Minnesota's apple breeding program, the Honeycrisp is a hybrid produced by breeding two different apples to create a new, crisper and juicier type of apple.

The inherent property of an agent or situation which has the potential to cause adverse effects when an organism, system or population is exposed to that agent, based on its chemical, physical or biological characteristics (e.g. the intrinsic hazard of sharp knife is to cut).

Median lethal concentration (LC50) is an indication of the lethal toxicity of a given substance, representing a concentration at which 50% of subjects die.

(Maximum Residue Level) The potential residues on a harvested crop are regulated by maximum level. 

Stalks, leaves, and cobs that remain in a cornfield after harvest. These materials are the primary source for cellulosic ethanol production and can at times be gathered for animal feeds or grazed. Also referred to as crop residue.

In agriculture, microbial products are those made from microorganisms to help protect crops from disease and pests, and to encourage healthy growth.

The process of managing the amount, source, timing, and method of nutrient (fertilizer) application, with the goal of optimizing farm productivity while minimizing nutrient losses that could create environmental problems.

No observable effect concentration, the concentration of a substance at which no effects were seen.

Impacts on animal wildlife, like pollinators, including endangered species.

"Any substance or mixture of substances used to alter the life cycle of any pest. They can be naturally derived or synthetically produced. Herbicide: pesticide for weeds Insecticide: pesticide for insects Fungicide: pesticide for fungus Miticide: pesticide for mites Nematicide: pesticide for nematodes"

The practice of planting more than one crop at a time in a particular region or field.

A safety margin is the factor that is added to account for uncertainties. For example, if a chronic test in fish showed no effects at 10μg/L, an assessment factor of 10 is still added, meaning that the acceptable concentration in water would be only 1μg/L. Safety factors in environmental risk assessments vary depending on area and test system, and are typically higher for the assessment of acute effects than for chronic effects.

Soil organic material is anything that was once alive and is now in or on the soil as it is decomposed into humus. Humus is organic material that has been decomposed by microorganisms and is readily changing form and mass as it decomposes.

A mycotoxin produced by Fusarium fungi species. Occurs mainly in cereals and corn. A potent estrogenic metabolite. In livestock known to cause infertility, abortion, breeding problems through the alteration of the hormone balance. Exposure of humans through the diet poses health concern due to the onset of several sexual disorders and alterations in the development of sexual apparatus.

Piping systems, most commonly corrugated plastic tubing, that are placed underneath the soil to remove excess water from a field of crops. This allows roots to develop to their desired depth and removes standing water from lower portions of the field. This also assists in minimizing erosion by helping excess water exit the field.

The practice of planting a single crop type in a particular region or field often for an extended period, one planting cycle after another.

Any substance or mixture of substances used to alter the life cycle of any pest. They can be naturally derived or synthetically produced. Herbicide: pesticide for weeds Insecticide: pesticide for insects Fungicide: pesticide for fungus Miticide: pesticide for mites Nematicide: pesticide for nematodes

Precision agriculture is the use of advanced technology, equipment, and data analytics to improve crop production practices. Farmers analyze data from their machines, from their fields, and even from satellite imagery to help them be more efficient and accurate with their use of natural resources, such as water, soil, and fuel, as well as their use of inputs, such as fertilizer and crop protection products.

Biotechnology, or genetic engineering, is the process of using living organisms to improve qualities of a plant such as the plant’s ability to protect itself against damage or improving upon its ability to grow and produce.

Crop scouting, also known as field scouting, is the very basic action of traveling through a crop field, usually on foot, while making frequent stops for observations. Crop scouting is done so that a farmer can see how different areas of his or her field are growing and what stressors or pests may be present. If there are problems during the growing season, the farmer can work to mitigate them so those problems do not affect yield at harvest time.

A planned sequence of planting crops over time on the same field. Rotating crops provides productivity benefits by improving soil nutrient levels and breaking crop pest cycles.

Such as weediness, potential gene flow to wild relatives, susceptibility to disease, and impacts on plant/insect interactions.

Lethal rate (LR50) is an indication of the lethal toxicity of a given substance, representing a rate at which 50% of subjects die.

(No Observable Adverse Effect Level) The highest dose where no recognizable harmful effects are observed. 

Conservation tillage includes all forms of reduced tillage. Tillage is the practice of plowing soil to prepare it for planting or after harvest to remove crop debris from the field. For example, ”no-till” involves no disturbance of the soil; and “reduced-till” or “strip-till” involves minimal disturbance. The benefits of this practice include improved moisture retention and reduced soil erosion.

Quality System, providing the formal framework for the conditions under which non-clinical health and environmental safety studies are planned, performed, monitored, recorded, reported, and archived. The details are laid down in legislative regulations as OECD Advisory Documents, EPA and FDA Good Laboratory Practice (GLP) rules and other national laws as e.g. German Chemical Law.

Crop protection is the collection of tools, products, and best practices farmers use to protect their crops from the negative impact of weeds, pests, and disease.

Pesticides applied directly to a seed before planting, for the purpose of protecting seeds, seedlings, and plants from pests.

Growth and development of the plant is as intended

No observable effect level, the level of exposure at which no effects of the substance were seen.

Cover crops are planted between growing seasons of a farmer’s primary cash crop, for the purpose of improving soil health, reducing erosion, improving soil fertility, and/or reducing soil compaction. There are three primary types of cover crops: tubers like the Tillage Radish; grasses like cereal rye, oats or annual rye grass; and legumes like clover. These cover crops are at times grazed or harvested, but most commonly are terminated through winter freeze or prior to the next crop planting season.

A safety margin is the factor that is added to account for uncertainties. For example, if a chronic test in fish showed no effects at 10μg/L, an assessment factor of 10 is still added, meaning that the acceptable concentration in water would be only 1μg/L. Safety factors in environmental risk assessments vary depending on area and test system, and are typically higher for the assessment of acute effects than for chronic effects.

Half maximal effective concentration (EC50) refers to the concentration of a substance which induces a response halfway between the baseline and maximum after a specified exposure time, i.e. the rate at which 50% of the maximal effect is observed

Median lethal dose (LD50) is an indication of the lethal toxicity of a given substance, representing a dose at which 50% of subjects die.
