Rice seed coated with an agricultural chemical

Abstract

The invention provides a rice seed coated with an agricultural chemical, characterized in that a rice seed is deprived of husk and the surface of said rice seed is coated with a binder containing an agricultural chemical. The rice seed is suitable to be germinated by maintaining the seed for at least three days at 20 to 40 degrees C.

1 . A rice seed coated with an agricultural chemical, comprising a rice seed deprived of husk and the surface of said rice seed being coated with a binder containing an agricultural chemical, and wherein said coated rice seed develops a radicle first before a coleoptile when germinated in aerobic conditions.  
   
   
       2 . The rice seed as claimed in  claim 1 , wherein said rice seed after de-husked is not washed.  
   
   
       3 . The rice seed as claimed in  claim 1 , wherein said rice seed is selected from the group consisting of  Oryza sativa  sp.  japonica, Oryza sativa  sp.  javanica, Oryza sativa  sp. indica, and hybrids thereof.  
   
   
       4 . The rice seed as claimed in  claim 1 , wherein said agricultural chemical is selected from the group consisting of fungicidal agents, bactericidal agents and insecticidal agents.  
   
   
       5 . The rice seed as claimed in  claim 4 , wherein a fungicidal or bactericidal agent is applied in an amount of 0.1 to 10 g per kg of the de-husked rice.  
   
   
       6 . The rice seed as claimed in  claim 4 , wherein an insecticidal agent is applied in an amount of 3 to 20 g per kg of the de-husked rice.  
   
   
       7 . The rice seed as claimed in  claim 4 , wherein the fungicide is selected from the group consisting of phenylpyrrole fungicides, azole fungicides, and strobilurine fungicides.  
   
   
       8 . The rice seed as claimed in  claim 4 , wherein the insecticide is selected from the group consisting of neo-nicotinide insecticides, carbazates insecticides, pyrethroid ether insecticides , and pyridine azomethine insecticides.  
   
   
       9 . The rice seed as claimed in  claim 1 , wherein the binder is selected from the group consisting of polyvinyl acetates, polyvinyl alcohols, and polyvinyl pyrrolidones.  
   
   
       10 . The rice seed as claimed in  claim 1 , wherein the binder is a mixture of 0 to 50% by weight of polyurethane and 100 to 50% by weight of polyvinyl alcohol.  
   
   
       11 . canceled  
   
   
       12 . The rice seed as claimed in  claim 11 , wherein said rice seed is to be germinated by maintaining the seed for at least three days at 20 to 40 degrees C.  
   
   
       13 . The rice seed as claimed in  claim 11 , wherein said rice seed is to be germinated by maintaining the seed for 4 to 9 days at 25 to 35 degrees C.  
   
   
       14 . The rice seed as claimed in  claim 11 , wherein said rice seed is to germinated by maintaining the seed around 30 degrees C.  
   
   
       15 . A method of germinating said seeds as claimed in  claim 1 , wherein said seeds are kept for at least three days at 20 to 40 degrees C. in aerobic conditions thereby lending to emergence of a radicle first before emergence of a coleoptile.
