Pesticide composition potentiated in efficacy and method for potentiating efficacy of pesticidal active ingredients

Abstract

The present invention provides a pesticide composition comprising a pesticidal active ingredient and a compound represented by chemical formula (I) or chemical formula (II) R—O-(EO) w -(PO) x -(EO) y -(PO) z -H  (I) R—O—(PO) w -(EO) x -(PO) y -(EO) z -H  (II) (wherein, BO represents an ethyleneoxy group, PO represents a propyleneoxy group, R represents an alkyl or alkenyl group having 8 to 20 carbons, w represents on average an integer in the range of 1 to 25, x represents on average an integer in the range of 1 to 25, y represents on average an integer in the range of 1 to 25, and z represents on average an integer in the range of 1 to 25). Further the present invention provides a method for potentiating the efficacy of the pesticidal active ingredient comprising using a compound represented by chemical formula (I) or chemical formula (II) in combination with a pesticidal active ingredient.

1 . A pesticide composition comprising
 a pesticidal active ingredient and   a compound represented by chemical formula (I) or chemical formula (II)
   R—O-(EO) w -(PO) x -(EO) y -(PO) z -H  (I) 
   R—O—(PO) w -(EO) x -(PO) y -(EO) z -H  (II) 
   
       (wherein, EO represents an ethyleneoxy group, PO represents a propyleneoxy group, R represents an alkyl or alkenyl group having 8 to 20 carbons, w represents on average an integer in the range of 1 to 25, x represents on average an integer in the range of 1 to 25, y represents on average an integer in the range of 1 to 25, and z represents on average an integer in the range of 1 to 25). 
     
     
         2 . The pesticide composition according to  claim 1 , wherein
 said pesticidal active ingredient is a neonicotinoid type compound.   
     
     
         3 . The pesticide composition according to  claim 2 , wherein
 said neonicotinoid type compound is acetamiprid.   
     
     
         4 . The pesticide composition according to any one of  claims 1  to  3 , further comprising a solvent. 
     
     
         5 . The pesticide composition according to any one of  claims 1  to  3 , further comprising an adsorption carrier. 
     
     
         6 . A method for potentiating the efficacy of a pesticidal active ingredient, comprising using a compound represented by chemical formula (I) or chemical formula (II)
   R—O-(EO) w -(PO) x -(EO) y -(PO) z -H  (I)     R—O—(PO) w -(EO) x -(PO) y -(EO) z -H  (II)   
       (wherein, EO represents an ethyleneoxy group, PO represents a propyleneoxy group, R represents an alkyl or alkenyl group having 8 to 20 carbons, w represents on average an integer in the range of 1 to 25, x represents on average an integer in the range of 1 to 25, y represents on average an integer in the range of 1 to 25, and z represents on average an integer in the range of 1 to 25) 
       in combination with a pesticidal active ingredient.
