Synergistic pesticidal compositions and related methods

Abstract

A pesticidal composition comprises a synergistically effective amount of a ryanodine receptor modulator compound and a pesticide selected from N-(3-chloro-1-(pyridin-3-yl)-1H-pyrazol-4-yl)-N-ethyl-3-((3,3,3-trifluoropropyl)thio)propanamide (I), N-(3-chloro-1-(pyridin-3-yl)-1H-pyrazol-4-yl)-N-ethyl-3-((3,3,3-trifluoropropyl)sulfinyl)propanamide (II), or any agriculturally acceptable salt thereof. A method of controlling pests comprises applying the pesticidal composition near a population of pests. A method of protecting a plant from infestation and attack by insects comprises contacting the plant with the synergistic pesticidal composition.

         6 . The composition of  claim 1 , wherein a weight ratio of the pesticide selected from (I), (II) or any agriculturally acceptable salt thereof to the ryanodine receptor modulator compound is no more than about 256:1. 
     
     
         7 . The composition of  claim 1 , wherein a weight ratio of the pesticide selected from (I), (II) or any agriculturally acceptable salt thereof to the ryanodine receptor modulator compound is no more than about 72:1. 
     
     
         8 . The composition of  claim 1 , wherein a weight ratio of the pesticide selected from (I), (II) or any agriculturally acceptable salt thereof to the ryanodine receptor modulator compound is no more than about 32:1. 
     
     
         9 . The composition of  claim 1 , wherein a weight ratio of the pesticide selected from (I), (II) or any agriculturally acceptable salt thereof to the ryanodine receptor modulator compound is no more than about 16:1. 
     
     
         10 . The composition of  claim 1 , wherein a weight ratio of the pesticide selected from (I), (II) or any agriculturally acceptable salt thereof to the ryanodine receptor modulator compound is no more than about 8:1. 
     
     
         11 . The composition of  claim 1 , wherein a weight ratio of the pesticide selected from (I), (II) or any agriculturally acceptable salt thereof to the ryanodine receptor modulator compound is no more than about 6:1. 
     
     
         12 . The composition of  claim 1 , wherein a weight ratio of the pesticide selected from (I), (II) or any agriculturally acceptable salt thereof to the ryanodine receptor modulator compound is no more than about 4:1. 
     
     
         13 . The composition of  claim 1 , wherein a weight ratio of the pesticide selected from (I), (II) or any agriculturally acceptable salt thereof to the ryanodine receptor modulator compound is no more than about 2:1. 
     
     
         14 . The composition of  claim 1 , wherein the weight ratio of the pesticide (I), (II), or any agriculturally acceptable salt thereof and the ryanodine receptor modulator is X:Y;
 wherein,   X is the parts by weight of the pesticide (I), (II), or any agriculturally acceptable salt thereof, and the numerical range is 0<X≦20;   Y is the parts by weight of the ryanodine receptor modulator, and the numerical range is 0<Y≦20.   
     
     
         15 . A method of controlling pests comprising applying the pesticidal composition of  claim 1 , near a population of pests, in an amount sufficient to control the pests. 
     
     
         16 . The method of  claim 15 , wherein the pests are brown stink bug ( Euschistus heros ), diamond back moth ( Plutella xylostella ), or a combination thereof.
