  • Patent number: 9198431
    Abstract: A method for controlling a pest on a crop includes applying a pesticide that comprises N6-(2-hydroxyethyl)-adenosine as an active ingredient for controlling the pest. The pesticide may include 20 wt % N6-(2-hydroxyethyl)-adenosine, 1-3 wt % dispersing agent, and 66.5% wt % water. The pesticide may further include a dispersion agent, a thickening agent, or an antifreeze agent as an auxiliary agent. The dispersing agent may be one or more selected from sodium lignin sulfonate, NNO, Agricultural Emulsifier 500#, Agricultural Emulsifier 700#, Agricultural Emulsifier 600#, Agricultural Emulsifier 1602#, methylene bis-methylnaphthalene sodium sulfonate, sodium salt of alkyl naphthalene sulfonate condensate, or polyoxyethylene castor oil. The thickening agent may be one or more selected from carboxymethyl cellulose, urea, poly vinyl alcohol, aluminum magnesium silicate, or xanthan gum.
