Crop Production

The production of crops is the heart of Nebraska's economy. Water is essential to all plant growth. Thus Nebraska's economy relies on a plentiful supply of water to produce crops – in both rainfed and irrigated environments. Several factors involved with producing crops interact with either water supply or water quality issues – or both.

Reducing Off-Site Movement of Atrazine and Pesticides

The US Environmental Protection Agency is conducting an intermediate reassessment of atrazine label certification to ensure the safety of atrazine found in streams for aquatic life and human health.
As part of this effort Syngenta was required to set up 40 monitoring stations in potential runoff sites across the Midwest.

Pesticide Drift Reduction & Prevention

Pesticide drift occurs when pesticides are transferred in air away from the intended application site into adjacent areas. Pesticides can move as spray droplets, vapor drift, or solid particle drift.

Pesticide Leaching & Runoff Management

Runoff and/or leaching can occur when pesticides are carried off the application site into water such as rivers, lakes and streams, wells, storm sewers, or into groundwater. Runoff/leaching can occur when too much pesticide is applied or is spilled on the surface, too much rainwater or irrigation water occurs in a short period of time, or highly water soluble pesticides are used.

To gain a better understanding of how, where and why water runs off and how to prevent pollution read the following UNL publications:

Chemical & Physical Characteristics of Pesticides

Understanding the chemical and physical characteristics of a pesticide allows the applicator to make better decisions about which pesticide active ingredient and/or formulation to use for a particular situation. Two chemical characteristics of interest are water solubility and volatility. The more water soluble a pesticide is, the greater the potential for runoff and leaching. The more volatile a pesticide is, the greater the potential for drift.
