On September 25, 2018, the only paraquat registration in China expired.
In 2013, Nanjing Red Sun was granted full registration of paraquat 20% GW, effective for a period of five years, which was due on September 25, 2018; thereafter, the production of paraquat 20% GW was terminated. Yet, the product developed before that date can still be sold and used within the validity period (two years) until September 25, 2020.
At the present time, the situation remains unclear about the availability of a substitute for paraquat after it was totally delisted from the market. It should be noted that the user’s deep impression of paraquat’s efficacy, fast action, and especially, its high price-performance ratio will impose a great challenge to other substitutes if their prices are higher, and the effect is not as good as paraquat.
