Examples of surfactants used for emulsification, dispersion, wet spreading and the like include anions such as alkyl sulfates, alkyl (aryl) sulfonates, dialkyl sulfosuccinates, and polyoxyethylene alkyl aryl ether phosphates. Examples include surfactants, nonionic surfactants such as polyoxyethylene alkyl ether, polyoxyethylene alkyl aryl ether, polyoxyethylene polyoxypropylene block copolymer, sorbitan fatty acid ester, and polyoxyethylene sorbitan fatty acid ester. Other auxiliaries for preparation include lignin sulfonate, alginate, polyvinyl alcohol, arbia gum, CMC (carboxymethyl cellulose), PAP (acidic isopropyl phosphate) and the like. The treatment concentration and treatment amount of the triazole-based plant growth regulator prepared in this manner vary depending on the type of plant growth regulator, treatment method, treatment time, and the like. ~ 200ppm solution 0.02 ~ 50g / a

【Example】

Hereinafter, the present invention will be described in more detail with reference to Formulation Examples and Test Examples. First, formulation examples are shown. In these preparation examples, parts represent parts by weight. Formulation Example 1 Emulsion Xylene is added to 5 parts of compound A, 10 parts of polyoxyethylene styrylphenyl ether and 50 parts of cyclohexanone to make 100 parts, and an emulsion is obtained by stirring and mixing. Formulation Example 2 Water dispersant 10 parts of compound B, 5 parts of sodium lauryl sulfate and 2 parts of a formalin condensate of an aromatic sulfonate were mixed with kaolin clay to make the whole 100 parts, mixed well with a juice mixer and then jet milled. A wettable powder is obtained by pulverization. Production Example 3 Granules 10 parts of compound C and 2 parts of white carbon are mixed and finely pulverized with a jet mill to obtain a pulverized product. 50 g of 12 g of this ground product of sodium dodecylbenzenesulfonate
% White carbon diluted powder 700g, bentonite 7.5kg
Then, kaolin clay is added to make the whole to 25 kg, mixed with a Nauta mixer for 15 minutes, 8.75 kg of water is added and kneaded, and then granulated by a field granulator. Further, granules are obtained by drying with a fluidized bed drier.

Next, test examples will be described. Test Example 1 Cucumbers (cultivar, Nanshin) were sown in synthetic resin pots filled with artificial soil and grown for 22 days. A 5 and 10 ppm solution of Compound A and a 50 ppm solution of Compound C prepared as emulsions according to Formulation Example 1 were sprayed with 4 ml of foliage per plant. A solution containing no active ingredient was sprayed with foliage as a control. Eight days after spraying, the plants were planted in the main field, cultivated, and the initial, middle and late yields were respectively investigated. The cultivation in this field is 10 strains per ward, ridge width 1.8m, double strain 0.5m between fertilizers, N 3.5kg / a, P ₂ O ₅ 2.5kg / a, K ₂ O
It was 3.0 kg / a. Table 1 shows the results of the yield investigation. Test Example 2 Cabbage (variety, Kinchun) was sowed in a synthetic resin pot filled with artificial soil and raised for 20 days. A 10- and 20-ppm solution of Compound A and a 100-ppm solution of Compound C prepared in an emulsion according to Formulation Example 1 were sprayed with 4 ml of foliage per plant. A solution containing no active ingredient was sprayed with foliage as a control. On the 15th day after spraying, the plants were planted in the main field, cultivated for 100 days, and the yield was examined. The cultivation in this field is 45 strains per ward, 2 rows, 0.6m ridge width, 0.4m spacing between plants, planting density 416 strains / a, fertilization rate is N3.5kg / a, P ₂ O ₅
It was 2.5 kg / a and K ₂ O 3.0 kg / a. Table 2 shows the results of the yield survey. Test Example 3 Compounds 1 and 3 prepared as wettable powders according to Formulation Example 2
And spinach (variety, dark green) seeds were immersed in a 10 ppm solution for 12 hours at the time of germination. Next, after washing with water, the seeds were sown in the main field in a simple house. A section sown with seeds immersed in water containing no compound A was used as a control. Cultivation in this field is 0.5m ² in 1 plot, 0.5m of ridge width in three consecutive systems, and fertilizer application amount is N 2kg /
a, P ₂ O ₅ 2 kg / a and K ₂ O 2 kg / a. All the plants were harvested 26 days later, and lottery rates and growth of non-lottery strains were investigated. The results are shown in Table 3. As shown in the above table, 70% or more of the strains in the control plot 3 had a drawer (rapid elongation of the stem with flower buds) and lost commercial value, whereas the control plot 7-9 treated with Compound A lost the commercial value. Lottery was suppressed. As a result, in the control plot 3, both the number of leaves and the fresh weight of the non-lottery strain as a harvest control were lower than those in the test plot 7-9. Test Example 4 Seeds of radish (cultivar, disease-resistant gross weight) were immersed in a 1 and 3 ppm solution of Compound A and a 25 ppm solution of Compound B prepared as wettable powders according to Formulation Example 2 for 24 hours, washed with water and returned to this field. Seeded. A section sown with seeds immersed in water containing no compound A or B was used as a control. Cultivation in this field is two-row sowing with a ridge width of 1.3m, a line between lines of 0.25m and a line between lines of 0.4m.
Zone 5.2m ² , 4 stations, fertilizer application rate N 2.4kg / a, P ₂ O ₅ 1.6k
g / a and K ₂ O 1.2 kg / a. After 85 days, all the plants were harvested and the growth was investigated. The results are shown in Table 4.
