Pesticide China Surface Water
15 May, 2019

On May 5, 2019, the Institute Control of Agrochemicals, Ministry of Agriculture (ICAMA) released the draft version of the Chinese Pesticide Surface Water Exposure Model (PSEM) for public consultation.
The model is designed for estimating the pesticide concentrations in surface water after pesticide application to dryland crops.

It is derived from the model PWC by US-EPA, and further incorporates Chinese specific scenarios, crop calendars, and meteorological data, etc. In addition, the rules on Mutual Acceptance of Data (MAD) in the pesticide registration in China are likely to impact timelines for product registration in China and delay market-access plans.

Please feel free to contact our Regulatory team in China (Dr. Xiaohua He) if you need support to run the draft model and preliminary calculations to better understand the impact on your products or regarding the new development on Mutual Acceptance of Data (MAD) in the pesticide registration – we have the expertise, methods, and tools.
