Rainbow Chemical obtains patent for 2, 4-D WG

China's State Intellectual Property Office (SIPO) recently granted the approval for the patent of “a formulating method for 2, 4-D salt WG,” developed by Chinese agrochemical company Rainbow Chemical (Patent No. 201210016942X, Authorization Certificate No. 2013051610077826).

 

This patent is for the formulating method of 2, 4-D WG, which is simpler and eco-friendly. There is no involvement of hazardous chemical substances, such as organic solvent, no discharge of the waste water and no generation of dust. The process fully reflects the production aim of Rainbow: Safer, greener and cleaner. The final product is highly concentrated, reaching up to 96% calculated by salt. It greatly decreases the cost of packaging, transportation and storage. Besides this, the WG formulation can also solve the problems encountered by other formulations, such as the EC, which could cause pollution, the SL which tends to drift in the field, and other formulations which are likely to delaminate, decompose, precipitate or crystallize after long-time storage. 

 

With the advantages of eco-friendly production, high concentration, low-cost transportation and storage, and convenient usage, this new formulation also improved the compatibility when mixed with other main herbicides, such as glyphosate and dicamba, atrazine. 2,4-D WG has shown its strong advantage and competitiveness in the market.
