ICAMA’s Tips for Pesticide Registration in China

Zhao Yonghui, Vice director of ICAMA, offered some practical advice for 13 pesticides to “help companies avoid detours in registration,” according to a report from Chemlinked, by Reach24H Consulting Group.

The presentation was part of the 19th Pesticide Information Exchange Conference held in Nanjing. The products discussed included: glyphosate, chlorfenapyr, indoxacarb, paraquat, azoxystrobin, flubendiamide, ethofenprox. fipronil, brassinolide, ternary fungicides, seed treatment, thifluzamide, and dinotefuran.


Zhao’s presentation gave attendees recommendations about how companies interested in registering their products might avoid registrations delays. Here are a couple of his suggestions:

Glyphosate: mixture mechanism of glyphosate and glufosinate has not been clarified, and mixture percentage differs greatly. Analyst is still working on some verification experiments to prove the reasonability of mixture. At the same time, glufosinate as compounding products, the mixture of glyphosate and glufosinate should also meet regulatory requirements of glufosinate.

Indoxacarb: the National Pesticide Standardization Committee updated indoxacarb content on S isomer. Previous indoxacarb registration on technical material normally contains up to 70% active substance. The committee suggests registering on technical concentrate rather than active constituent.

Paraquat: since production and application of paraquat cause huge damage to human health, no more new registration will be approved in the future. Paraquat is clarified as highly toxic pesticide based on result of acute oral, dermal and inhalation toxicity tests. Since safety question has not been solved effectively, committee would no more accept or approve new or renewal registration. Current paraquat registration would be cancelled in a proper time.
