JPS61143305A - Method for preventing succulent growth of tulip - Google Patents

Abstract

PURPOSE:To prevent the succulent growth of tulip, surely and easily with a small amount agent, by dipping the bulb of tulip in an aqueous solution of (E)-1-4,4-dimethyl-2-(1,2,4-triazol-1-yl)-1-penten-3-ol. CONSTITUTION:In the case of the culture of tulip on a flower-bed or in a pot, the penduncle is liable to cause the succulent growth by the hot weather in early spring resulting in the droop of the flower. The succulent growth of tulip can be prevented by dipping the bulb of tulip in an aqueous solution of (E)-1- cyclohexyl-4,4-dimethyl-2-(1,2,4-triazol-1-yl)-1-pent-en-3-ol (1-5,000 ppm, preferably about 50-100 ppm concentration) before planting. The succulent growth can be prevented easily, and a high-quality tulip having thick and rubust peduncle can be cultured by this process.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides tulip bulbs with (E+-1-cyclohexyl-4,4-dimethyl-2-(1°2.4-triazol-1-yl)-1-penten- The present invention relates to a method for preventing tulips from elongating by immersing them in an aqueous solution of 3-ol (hereinafter referred to as compound A).

Among bulb petals, tulips are the most popular, highly marketable, and have a wide cultivation area, but when grown in flower beds or in pots, the rise in temperature in early spring causes the flower stems to elongate and the flower heads to droop. There is a problem. On the other hand, the building agent ancymidol (α-cyclopropyl-α-(p-
It was found that the effect of preventing growth can be expected by treating soil with methoxyphenyl)-5-pyrimidylmethanol (M, 5nel and E, Eysel).

When treating potted tulips, it is necessary to individually inject a predetermined amount of a liquid with a predetermined concentration, which has the disadvantage of requiring a great deal of labor.

Furthermore, as environmental pollution caused by pesticides has become a problem in recent years, there is a need for a method that can effectively prevent growth with a small amount of application.

As a result of intensive research into a method to more easily and reliably prevent the elongation of tulip bulbs at a lower dose, the present inventors discovered that compound A (Japanese Unexamined Patent Publication No. 55-111
It was discovered that by soaking tulips in an aqueous solution (No. 477) and then planting them, the elongation of tulip flower stalks could be easily prevented and at a low dose, and the method of the present invention was completed.

The method of the present invention will be explained in more detail below.

According to the method of the present invention, the previous tulip bulbs are planted with the compound Ano1-5000pIXn for 1 minute to 24 hours, preferably 5 minutes to 1 hour.

Preferably, if the tulips are immersed in an aqueous solution of 60 to 11,000 ppm before planting, not only will the tulips be easily prevented from elongating, but the flower stems will also grow thick and strong, making it possible to grow high-quality tulips.

An aqueous solution of Compound A can be obtained not only by dissolving Compound A in an organic solvent such as methanol, ethanol, acetone, acetonitrile, etc. and diluting it with water, but also by mixing Compound A with a carrier and an adjuvant to prepare a plant growth regulator. It can also be obtained by diluting commonly used formulations such as wettable powders, emulsions, flowable preparations, liquid preparations, etc. with water.

Furthermore, when tulips are immersed in an aqueous solution of Compound A, they may be treated together with an insecticide, a fungicide, a plant growth regulator, or the like.

Next, a test example will be given to demonstrate the effect of preventing chew chips from becoming elongated by the method of the present invention.

Test Example 1 Tulip bulbs (variety: Golden Harvest) were refrigerated at 5° C. for about 2 months, and then immersed in an aqueous solution of Compound A or Ancimidol diluted to a predetermined thickness for a predetermined period of time. After air drying, plant in No. 6 plastic pots, 22
Cultivated in a greenhouse at ~27°C.

The test was repeated 8 times for each, and the flower stem length was measured at the time of flowering (one month after planting), and the average length for each treatment plot was determined. The results are shown in Table 1, and the flower stalk length is expressed as a percentage of the untreated plot.

In addition, since environmental pollution caused by pesticides has become a problem these days, there is a need for a method that can effectively prevent growth by applying a small amount of pesticides.
