When BPH attacks rice crop during flowering and grain hardening stage, it necessitates a pesticide application. That application(s) is likely to lead pesticide residues in grain. Such residue can be harmful to the health of the consumer or can become a cause of rejection of the grain when exported to foreign countries. Hence it is essential to have understanding about the residues of various pesticides recommended against BPH (and/or other pests) with regard to their residue implications. This paper describes briefly the analytical procedures for some important insecticides recommended and used against BPH like buprofezin, ethofenprox, thiamethoxam, chlorantraniliprole, Imidacloprid, pymetrozine, cyantraniliprole, fipronil and denotefuran, in different rice growing countries with special reference to their implications in international rice trade. However, it is painful to admit that there are no analytical methods available in literature for ethiprole and sulfoxaflor residue analysis in rice grain.
