[Table] The characteristics of the compound represented by the above general formula () are that it can be dissolved or dispersed in water and sprayed as an aqueous solution, or treated in soil and absorbed by plants to improve the growth of the above-ground parts of plants. The goal is to not only promote the growth of the plant, but also to significantly increase the growth of the underground portion. A compound that simultaneously promotes the growth of the above-ground and underground parts is of great value in terms of crop production, especially for transplanting crops, and is also a compound with excellent safety. When the compound of the present invention is actually used, it can be used as it is, but it can also be used as a solution, wettable powder, emulsion, oil, suspending agent, powder, granule, etc. depending on the situation and purpose of use. Can be done. In addition, for formulation, it can be mixed with various solid and liquid carriers used in the preparation of general concentrated medicines to form preparations. Furthermore, adjuvants and the like may be added to this drug. Further, depending on the purpose of use, the above-mentioned components can be used in combination with insecticides, fungicides, herbicides, fertilizers, etc. When actually using this drug, it is natural to vary the content of the active ingredient over a wide range of concentrations depending on the plant situation, usage situation, or formulation form;
A concentration range of 1000 ppm is suitable. Next, the present invention will be explained by giving experimental examples. Experimental Example 1 Hydroponic Test on Rice Emulsions containing each of Compound Nos. 1 to 9 in Table 1 as active ingredients were produced as follows. Active ingredient: 50 parts Nucalgen 2525P 10 parts (manufactured by Takemoto Yurushashi Co., Ltd.) Kinroll 40 parts These were thoroughly mixed until homogeneous and dissolved to form an emulsion. Dilute the emulsion with water to obtain an active ingredient concentration of 100,
10. It was made into a 1 ppm solution and placed in a hydroponic culture device.
Next, rice seeds (variety:
Nipponbare) was sown in a hydroponic device and grown in a growth chamber (30℃, 90% humidity) for 13 days.
The plant height and root length of 20 individuals were measured, and the untreated versus untreated plots were determined. The results are shown in Table 2.
