Pesticidal/ovicidal composition and pesticidal/ovicidal method

Abstract

A pesticidal/ovicidal composition comprising (a) 50-99.9 parts by mass of a triglyceride containing not less than 50% of oleic acid as a fatty acid component; (b) 0.1-20 parts by mass of a nonionic surface active agent; and (c) 0-30 parts by mass of a glycerin derivative. The composition according to the invention has not only a pesticidal activity but also an ovicidal activity on crop pests, and provides a safe and high pesticidal/ovicidal effect.

1 . A pesticidal/ovicidal composition comprising:
 (a) 50-99.9 parts by mass of a triglyceride containing not less than 50% of oleic acid as a fatty acid component;   (b) 0.1-20 parts by mass of a nonionic surface active agent; and   (c) 0-30 parts by mass of a glycerin derivative.   
   
   
       2 . The pesticidal/ovicidal composition according to  claim 1 , wherein said nonionic surface active agent is at least one selected from the group consisting of fatty acid esters and amino acid derivatives. 
   
   
       3 . The pesticidal/ovicidal composition according to  claim 2 , wherein said nonionic surface active agent is a fatty acid ester, wherein said fatty acid ester is at least one selected from the group consisting of polyoxyethylene fatty acid esters, sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters and polyoxyethylene glyceryl ether fatty acid esters. 
   
   
       4 . The pesticidal/ovicidal composition according to  claim 3 , wherein said fatty acid ester is a polyoxyethylene fatty acid ester, wherein said polyoxyethylene fatty acid ester is at least one selected from the group consisting of polyoxyethylene castor oil, and polyoxyethylene hydrogenated castor oil. 
   
   
       5 . The pesticidal/ovicidal composition according  claim 1 , further comprising:
 (d) a lower alcohol in an amount not more than 10 parts by mass; and/or   (e) a vegetable oil in an amount not more than 39 parts by mass,   
     relative to 100 parts by mass of the total amount of the components (a), (b) and (c). 
   
   
       6 . The pesticidal/ovicidal composition according to  claim 1 , which is diluted by 100-fold to 1000-fold with water. 
   
   
       7 . A pesticidal/ovicidal method which comprises the step of spraying to crops the pesticidal/ovicidal composition according to  claim 1 , in such an amount that the total amount of the components (a), (b) and (c) is in the range between 0.2 kg/10 a and 8 kg/10 a. 
   
   
       8 . The pesticidal/ovicidal method according to  claim 7  which comprises the step of spraying to crops the pesticidal/ovicidal composition, in such an amount that the total amount of the components (a), (b) and (c) is in the range between 0.5 kg/10 a and 3 kg/10 a.
