Abstract

Abstract Stable agrochemical compositions are provided by incorporating at least one of the alpha -unsaturated amine derivatives having the following formula: <CHEM> wherein one of X<1> and X<2> is an electron attracting group and the other is hydrogen or an electron attracting group; R<1> is a group attached through a nitrogen atom; R<2> is hydrogen or a group attached through a carbon, nitrogen, or oxygen atom; n is an integer of 0, 1, or 2; and A is a substituted or unsubstituted heterocyclic group or a substituted or unsubstituted cyclic hydrocarbon group; and salts thereof, into an agrochemically acceptable solid carrier (clay minerals capable of adsorption (including fuller's earth, terra alba, bentonite, and activated fuller's earth), zeolite, activated charcoal, and beta -cyclodextrin, etc.) under a pH 5.5 or less condition. The agrochemical (pesticidal) compositions exert potent shelf life and light-resistance.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 126 words
An agrochemical composition which comprises: (i) at least one α-unsaturated amine derivative having the following formula: ##STR25## wherein B a is a substituted or unsubstituted pyridyl or thiazolyl group, and R 8a , R 9a and R 10a are each independently hydrogen; an alkyl, alkenyl, alkynyl, cycloalkyl, acyl, or alkoxycarbonyl group, or an agrochemically acceptable salt thereof; (ii) an acid whose dissociation constant is at least about 1×10 -3 ; and (iii) an agrochemically acceptable solid carrier which is capable of adsorbing at least 5.0×10 -2 mmol/g of the α-unsaturated amine derivative or salt thereof from a solution or suspension adjusted to a pH less than or equal to 5, both the α-unsaturated amine derivative and the acid each being incorporated into the agrochemically acceptable carrier.
Claim 2
Dependent Claim 126 words
An agrochemical composition which comprises: (i) at least one α-unsaturated amine derivative having the following formula: ##STR25## wherein B a is a substituted or unsubstituted pyridyl or thiazolyl group, and R 8a , R 9a and R 10a are each independently hydrogen; an alkyl, alkenyl, alkynyl, cycloalkyl, acyl, or alkoxycarbonyl group, or an agrochemically acceptable salt thereof; (ii) an acid whose dissociation constant is at least about 1×10 -3 ; and (iii) an agrochemically acceptable solid carrier which is capable of adsorbing at least 5.0×10 -2 mmol/g of the α-unsaturated amine derivative or salt thereof from a solution or suspension adjusted to a pH less than or equal to 5, both the α-unsaturated amine derivative and the acid each being incorporated into the agrochemically acceptable carrier.
Claim 3
Dependent Claim 22 words
The agrochemical composition according to claim 1, in which B a is a group having the formula: ##STR26## wherein Hal is halogen.
Claim 4
Dependent Claim 68 words
The agrochemical composition according to claim 1, comprising a compound of the formula: ##STR27## wherein R 8 b, R 9 b, and R 10 b are each independently hydrogen or an alkyl group, and Hal is halogen, or ##STR28## wherein R 8 c, R 9 c, and R 10 c are each independently hydrogen or an alkyl group, and Hal is halogen, or an agrochemically acceptable salt thereof.
Claim 5
Dependent Claim 21 words
