Bayer successfully defended its patent for its proprietary Mefenpyr-diethyl safener in Chinese court, reported from China Daily.

Bayer CropScience filed a lawsuit against two Chinese crop protection product producers, Jiangsu Tianrong Group and Yixing Huadong Agro-Chemical Co. Ltd in 2008. The lawsuit was filed in Wuxi Intermediate Peoples Court in Jiangsu province.

Bayer CropScience said the companies sold the products illegally to local farmers, as well as to other customers in other Asian countries.

Safeners are added to herbicides to protect crops by ensuring the rapid degradation of herbicidal substances in crop plants. The safeners accelerate their degradation to prevent damage to the plants.

Mefenpyr-diethyl is a proprietary Bayer CropScience safener additive. Bayer sells its patented Mefenpyr-diethyl products around the world in combination with Fenoxaprop-P-ethyl and other active ingredients to protect crops.
