Step 2 The correct environmental assessment form needs to be completed and reviewed. [7] Step 3 A coordinated review is set up by all agencies involved in Type 1 Actions. [8] Step 4 This is the step where the agency that is taking the lead will make its determination on the significance. [9]

Pesticide application is the practical way in which pesticides (including herbicides, fungicides, insecticides, or nematode control agents) are delivered to their biological targets (e.g. pest organism, crop or other plant).
The timing of application is crucial as the moisture content of the grain must be below 30% for the yield of the crop to be unaffected and to minimize uptake of glyphosate by the grain. [23] Yield may be affected and residues increased if applications are made to uneven fields in which some areas have a moisture content over 30%.
The glyphosate-based herbicide RoundUp (styled: Roundup) was developed in the 1970s by Monsanto. Glyphosate was first registered for use in the U.S. in 1974. [4] Glyphosate-based herbicides were initially used in a similar way to paraquat and diquat, as non-selective herbicides. Attempts were made to apply them to row crops, but problems with ...
Glyphosate is absorbed through foliage and minimally through roots, meaning that it is only effective on actively growing plants and cannot prevent seeds from germinating. [56] [57] After application, glyphosate is readily transported around the plant to growing roots and leaves and this systemic activity is important for its effectiveness.
Enforcing environmental quality laws often includes investigating timber thefts, water pollution, improper use or application of pesticides, commercial vehicles producing excessive emissions, wetland degradation, illegal mining, and almost any area that affects air, land, or water quality violations.
Atrazine is the second-most commonly used herbicide in the United States after glyphosate, with application of approximately 76,000,000 pounds (34,000 t) of the active ingredient in 1997.
Application of glyphosate-based herbicides to row crops resulted in problems with crop damage and kept them from being widely used for this purpose. In the United States, use of Roundup experienced rapid growth following the commercial introduction of a glyphosate-resistant soybean in 1996. [75] "Roundup Ready" became Monsanto's trademark for ...
