In addition, chemical compatibility refers to the container material being acceptable to store the chemical or for a tool or object that comes in contact with a chemical to not degrade. For example, when stirring a chemical, the stirrer must be stable in the chemical that is being stirred. Many companies publish chemical resistance charts.
As of 2005, 87% of U.S. soybean fields were planted with glyphosate resistant varieties. [ 7 ] [ 8 ] While the use of Roundup Ready crops has increased the usage of herbicides measured in pounds applied per acre, [ 9 ] it has also changed the herbicide use profile away from atrazine , metribuzin , and alachlor [ citation needed ] which are more ...
Increased concerns for resistance with seed mixtures include partially resistant larvae on a Bt plant being able to move to a susceptible plant to survive or cross pollination of refuge pollen on to Bt plants that can lower the amount of Bt expressed in kernels for ear feeding insects. [220] [221]
However, disease control is reasonably successful for most crops. Disease control is achieved by use of plants that have been bred for good resistance to many diseases, and by plant cultivation approaches such as crop rotation, pathogen-free seed, appropriate planting date and plant density, control of field moisture, and pesticide use.
A Film coating, a layer of thin film applied to the seed typically less than 10% of the mass of the original seed. Encrustment, where the applied material is typically 100%–500% of the original seed mass, but the shape is still discernible. Pellet, where the applied material is so thick that the seed's original shape is not discernible.
Monsanto's introduction of this system (planting a glyphosate-resistant seed and then applying glyphosate once plants emerged) allowed farmers to increase yield by planting rows closer together. [116] Without it, farmers had to plant rows far enough apart to allow the control of post-emergent weeds with mechanical tillage. [116]
Variety-specific genetic use restriction technologies destroy seed development and plant fertility by means of a "genetic process triggered by a chemical inducer that will allow the plant to grow and to form seeds, but will cause the embryo of each of those seeds to produce a cell toxin that will prevent its germination if replanted, thus ...
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.
