Application of herbicides (Daniel Etter (www.schweizerbauer.ch))
The land user interviewed has an experience of nearly 30 years with the application of herbicide to his fields. Through this time he learned that there are ways to reduce the amount of herbicide and thereby conserve soil and nature against this aggressive pesticide. There are different factors to consider to reduce the herbicide application such as time of the day to bring out herbicides or time of the year. For example there is less herbicide needed the earlier in the morning it is applied to the field.
Purpose of the Technology: There are two main purposes of the technology. The fist is to protect crops and to not damage them with great amounts of herbicides. Thereby, also environment as a whole and especially waters are protected because there is always a part of herbicides washed out of soils and into waters. The second aim is more economically. As the effectiveness of the application of herbicides is worse in spring than in autumn, it should be prohibited by law to use herbicides in spring. On the other hand, land users should be allowed to use herbicides for a longer time in autumn because crops tend towards dormancy. Thereby, not only the amount of herbicides applied to a field can be reduced but the land user is also saving money.
Establishment / maintenance activities and inputs: The establishment and maintenance of the technology requires first of all a great deal of knowledge. To receive the desired target situation there are many points to be discussed of the current situation with herbicide application. One point is the free pass which enables land users with a basic education to practice pest management even if they do not know what a pest management gun is and how it is used. A solution to this problem of lack of knowledge is seen by the land user through the structural change in agriculture. Companies providing spraying services are more efficient and tidy than the land user can be.
Natural / human environment: The technology helps protecting the environment and waters from pollution through washed out herbicides. This must always be kept in mind when discussing about the amount of herbicides. Some land users do not trust a smaller amount of herbicides to be as effective as the standardized one. But this overthinking must now be made because it is until today not sure what side effects herbicides have to the human and natural environment.

Because of elimination of undesired crops. However risk that herbicide affects crop production itself
Because of increased crop yield
The fact that the consequences of herbicides e.g. glyphosate for human health are not yet known disturbs the public. Also land users do not agree on the benefit or damage to natural environment because of herbicides. Therefore, minimizing the amount of herbicides applied as much as possible is an important step. An overthinking of the current situation but also much more knowledge and research on this topic must be provided in order to improve livelihoods and human well-being even more.
