The objective of this experiment was to find out the effect of agro-chemicals on the lodging in paddy field. SiO2 added into soil up to 130 ppm and K2O applied 15kg/10a land preparation. 2.4-D sprayed 250g/10a on the 30 days after transplanting and kitatchin G applied 3kg/10a on the 30 days before heading. The most efficient agro-chemical to prevent lodging was kitatchin which applied 3kg/10a on the 30 days before heading. Generally, kitatchin and 2.4-D were reduced plant height and lodging index, but decreased grain yield
