Pethoxamide ( ISO recognized name) is a herbicide . It belongs to the chemical group of amides , more precisely to the chloroacetamides . It is a systemic herbicide that is ingested through roots and young shoots. Pethoxamide disrupts cell division and thus the growth of undesirable plants (various grasses and broad-leaved weeds) and is intended for use before or shortly after they germinate in maize , rice and soybean cultivation .

History and use

Pethoxamid was developed by the Japanese Tokuyama Corporation in cooperation with the Japanese Arysta LifeScience and the German Stähler Agrochemie . In 2000, on behalf of the other companies, Stähler Agrochemie sent a request to the European Commission to have pethoxamide included in Annex I (approved active substances) of European Directive 91/414 / EEC. The subsequent investigation did not reveal any problems, so that on July 7, 2006, the European Commission decided to include pethoxamide in Annex I and agents with pethoxamide could be approved in member states of the EU . The period of validity runs until July 31, 2016. In Belgium , the product Successor 600 based on pethoxamide from Stähler International (the former Stähler Agrochemie ) is approved for growing maize.

Pethoxamide is contained in pesticides that can be used in Germany in maize cultivation against chamomile , chicken millet and millet . In Switzerland and Austria, the active ingredient is also permitted in the cultivation of soy and oil pumpkins .

Admission

Pethoxamide is approved as an active ingredient in plant protection products in many EU countries, including Germany and Austria, as well as Switzerland.
