Thanks for your question,

In our experiments, the DE treatments were applied to maize kernels using a heavy-duty rotator (ROTO-TORQUE model 7637, ColeParmer, Vernon Hills, IL, USA).

For commercial or large scale application, I recommend you to contact your supplier of DE.

thanks, infact  we tried on walls of a bagged cargo storing RICE after making its paste but it was not  very successful. we cannot mix it with food grains  as per local laws that is why i need your help.
