PURPOSE:To obtain an agricultural chemical composition having synergistically raised promoting effects on rooting and taking roots of rice plant and growing effects on sound seedling, by using both choline, phosphorylcholine and/or a salt thereof and diisopropyl 1,3-dithiolan-2-indenemalonate. CONSTITUTION:An agricultural chemical composition which uses (A) one or more compounds selected from choline, phosphorylcholine and a salt thereof and (B) diisopropyl 1,3-dithiolan-2-indenemalonate as active ingredients in a molar ratio of the component A:B=1:10-2,000, preferably 1:20-500, has synergistically raised promoting effects on rooting of rice plant and preventing effects on heating of seedling, improves seedling quality thereby and provides sound seedlings, promotes rooting and taking roots of rice plant after plating to rice paddy fields and has improving effects on tillering, etc. |
