FIELD: chemistry.
SUBSTANCE: agricultural aqueous suspension chemical composition contains a compound represented by the following formula (I), or acceptable for agriculture and horticulture acid addition salt thereof as an active ingredient, the condensate alkyl naphthalene sulfonate and formalin, and one, or two or more compounds selected from the group consisting of alkyl sulfate, alkyl ether sulfate, polyoxyalkylene, alkylphosphoric acid and its salts, simple polioksialkilenphosphoric alkyl ester and salt thereof, and a simple alkyl polioksialkilenacetic ester acid and salts thereof, 
wherein R1 represents COR4' or COOR5 (wherein R4' and R5 represent a C1-4 alkyl group), R2 represents a C1-4 alkyl group, R3 represents a C1-4 alkyl group, X1 and X2, each independently, represent an atom hydrogen or C1-4 alkyl group optionally substituted by halogen atom, provided that X1 and X2 are not simultaneously a hydrogen atom, X3 represents a hydrogen atom, W1, W2 and W3 represent C-Y1, C-Y2 and C-Y3 respectively, Y1, Y2, Y3, Y4 and Y5, each independently represents a hydrogen atom, C1-8 alkyloxy or galogen atom (wherein C1-8 alkyloxy substituted by one or more halogen atoms, which may be identical or different, and/or C1-4alkiloksigruppoy substituted by one or more halogen atoms, which may be identical or different), in the condition that X1 and X2 are not simultaneously a hydrogen atom, X3 is a hydrogen atom, W1, W2 and W3 are C-Y1, C-Y2 and C-Y3 respectively, Y1, Y2, Y3, Y4 and Y5, each Independently represents a hydrogen atom, a C1-8 alkyloxy group or a halogen atom (wherein the C1-8 alkyloxy group is substituted by one or more halogen atoms which may be the same or different and/or a C1-4 alkyloxy group substituted by one or more halogen atoms which can Be the same or different), provided that at least one of Y1, Y2, Y3, Y4 Y5 is a C1-8 alkyloxy group (wherein the C1-8 alkyloxy group is substituted by one or more halogen atoms which may be the same or different and/or a C1-4 alkyloxy group substituted by one or more halogen atoms which may be the same or different), Or two adjacent groups selected from Y1, Y2, Y3, Y4 and Y5 can be taken together to form -O-(CH2)nO- substituted with one or more halogen atoms (where n is 1 or 2) and Z is an oxygen atom.
EFFECT: invention makes it possible to increase the effectiveness of pest control and storage stability.
