A herbicidal emulsion composition comprising an ethenylamide compound as a herbicidally active component and a dichloroacetamide compound as a phytotoxicity reducing agent. This composition has excellent keeping stability because the phytotoxicity reducing agent of the composition does not decompose and crystals do not separate out even when it is kept for a long time. An amino alcohol and a polar nonaqueous solvent as a solvent are added to the ethenylamide compound and the dichloroacetamide compound to prepare a herbicidal emulsion composition.

The present invention relates to a herbicidal emulsion composition which comprises an ethenylamide compound as a herbicidally active component and a dichloroacetamide compound as a phytotoxicity reducing agent.
It is known that ethenylamide compounds have excellent therbicidal activity (refer to JP-B 5-15699) (the term “JP-B” as used herein means an “examined Japanese patent publication”). Out of these, an ethenylamide compound having an aryl group or heteroaryl group at the 1-position of an ethenyl group may be used as a herbicide for broad-leaved crops such as soybeans, cotton and beets, and the crops of the gross family such as wheat, barley, corn and upland rice. However, phytotoxicity such as the dead or yellowed leaves of cultivated crops, the suppressed growth of the crops or the reduced yield may occur according to the type of the soil of the crop cultivation land, the amount of water content or temperature.
It is known that a phytotoxicity reducing agent is used as means of reducing such phytotoxicity. It is also known that the above ethenylamide compound is used in conjunction with a phytotoxicity reducing agent such as a dichloroacetamide compound to prevent the occurrence of phytotoxicity (refer to JP-A 11-79906) (the term “JP-A” as used herein means an “unexamined published Japanese patent application”).
The following examples are provided for the purpose of further illustrating a hercidal emulsion composition the present invention but are in no way to be taken as limiting.
In Examples, compounds No. 1 to 20 shown in Tables 1 and 2 were used as the ethenylamide compound and compounds A to J shown in Tables 3 and 4 were used as the dichloroacetamide compound. 1 TABLE 1 5 No R1 R2 R3 R4 R5 1 6 CH3 CH3 CH2CH2OC2H5 CH2Cl 2 7 CH3 CH3 CH2CH2OCH3 CH2Cl 3 8 H H 9 CH2Cl 4 10 H CH3 CH2CH2OC2H5 CH2Cl 5 11 CH3 CH3 (CH2)3OCH3 CH3 6 12 H H (CH2)4CH3 CH2Br 7 13 CH3 CH3 (CH2)3OC2H5 CH(CH3)2 8 14 CH3 C2H5 15 CH2Cl 9 16 CH3 CH3 (CH2)3OC3H7 17 10 18 C2H5 H 19 20
