wherein, R 1a represents a linear or branched, alkyl or alkenyl group having 10 to 16 carbon atoms; EO represents an ethyleneoxy group; 1 represents an average mole number of ethyleneoxy groups added, ranging from 3 to 40; and R 2a represents a hydrogen atom or a methyl group,
(A2): a polyoxyethylene fatty acid ester,
wherein a fatty acid group has 8 to 16 carbon atoms; and an average number of moles of ethylene oxide added per mole of fatty acid is 5 to 40,
(A3): a polyoxyethylene sorbitan fatty acid ester,
wherein a fatty acid group has 8 to 16 carbon atoms; and an average number of moles of ethylene oxide added per mole of fatty acid is 5 to 40,
(A4): a (poly)glycerol fatty acid ester,
wherein a fatty acid group has 8 to 16 carbon atoms; and an average condensation degree of glycerol is 1 to 3, and
(A5): an alkyl saccharide represented by the formula (A5):
R 3a —O-(G) p   (A5)

wherein R 3a represents an alkyl group having 8 to 16 carbon atoms; G represents a reducing sugar group having 5 to 6 carbon atoms; and p represents a number of 1 to 10;
(B1): a polyoxyalkylene alkyl ether represented by the formula (B1):
R 1b O—[(PO) m /(EO) n ]—R 2b   (B1)

wherein, R 1b represents a linear or branched, alkyl or alkenyl group having 6 to 12 carbon atoms; PO represents a propyleneoxy group; EO represents an ethyleneoxy group; m represents an average mole number of propyleneoxy groups added, ranging from 2 to 20; n represents an average mole number of ethyleneoxy groups added, which is 0; and R 2b represents a hydrogen atom or a methyl group; wherein “/” means that PO and EO groups may be arranged at random or in blocks, and
(B2): an aliphatic alcohol represented by the formula (B2):
R 3b —OH  (B2)

wherein R 3b represents a linear or branched, alkyl group having 8 to 10 carbon atoms, and wherein a weight ratio of compounds (A) to (B), (A)/(B), is 0.5 to 8.

2. The method for producing an agricultural product according to claim 1 , provided that when B is (B1) then A is (A1), and when B is (B2) then A is (A2) or (A4).

3. The method for producing an agricultural product according to claim 1 , wherein the total weight of compounds (A) and (B)/the weight of the agricultural chemical ingredient is from 0.1 to 100.

4. The method for producing an agricultural product according to claim 1 , wherein the agricultural chemical composition further comprises water and/or an organic solvent.

5. The method for producing an agricultural product according to claim 1 , comprising contacting the agricultural chemical composition with a part of a plant where a water contact angle is 50 to 180 degrees.

6. The method for producing an agricultural product according to claim 1 , wherein the total content of compounds (A) and (B) in an agricultural chemical preparation for spray is 30 to 50000 ppm.

7. The method for producing an agricultural product according to claim 1 , comprising spraying the agricultural chemical preparation for spray in an amount of 1 to 500 L/10a.

8. A method for producing an agricultural product, comprising a step of applying an agricultural chemical composition comprising (A) at least one compound selected from the group consisting of the following (A1) to (A5); (B) at least one compound selected from the group consisting of the following (B1) and (B2); and an agricultural chemical ingredient selected from the group consisting of active ingredients in bactericides, pesticides, miticides, herbicides and plant growth regulators to a subject sensitive to the agricultural chemical ingredient:
