Abstract

PURPOSE:To provide a plant-growth regulator exhibiting a specific high plant- growth regulating effect, especially a synergistic effect on the acceleration of the coloration of apples, by adding dichloroprop and/or its salt to choline and/or its salt. CONSTITUTION:Choline and/or its salt (especially desirably choline chloride or choline phosphate) and dichloroprop, namely 2-(2,4-dichlorophenoxy) propionic acid and/or its salt, desirably 300-3000ppm, especially 50-1500ppm, of the choline salt and 30-5000ppm, especially 40-300ppm, of the dichloroprop are compounded in a mixing ratio (weight ratio) of 1:0.01 to 1:1, especially 1:0.03 to 1:0.5, to obtain the plant-growth regulator. When applied to fruits such as apples, pears, citrus fruits, the plant-growth regulator exhibits effects on the prevention of their preharvest dropping, calyx falling, etc., especially exhibits high effects on the coloration acceleration and mature data promotion of the apples without damaging the qualities of the apples.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the above-mentioned JP-A-61-115501, the inventors have found that choline salt is effective in increasing the yield of various crops. Choline salt has an effect of promoting rooting of rice, an effect of promoting photosynthesis of wheat, and an effect of increasing the yield of onions, sweet potatoes, onions and the like. However, the action of choline salt as a plant growth regulator is not always sufficient, and further improvement is desired. On the other hand, dichloroprop [triethanolamine = 2- (2,4 dichlorophenoxy) propionate]
It was first discovered in 1945 as a plant growth regulator, and is currently used to prevent fallout of apples and pears before harvest, Iyokan, Amanatsu, and navel stagnation.

[Means for Solving the Problems] The inventors conducted field tests by adding various compounds for the purpose of improving the action and effect of choline salts. As a result, when dichloroprop was added to choline salt, it showed a specific high plant growth regulator effect that was not seen when choline salt and dichloroprop were used alone. The present invention has been completed by finding that it exhibits a high specific effect which is not seen when each of them and dichloroprop are used alone. That is, the present invention is a plant growth regulator comprising at least one choline salt and dichloroprop, and a plant growth regulator using the choline salt and dichloroprop.

Test Example 1 Apples (cultivar Tsugaru) were sprayed on August 11 (28 days before harvesting) with a backpack-type semi-automatic sprayer so that each of the chemicals could be sufficiently wetted with the fruits and leaves (about 4 L per tree). .. For spraying, a surfactant (approach BI 1,000 times) was added. In addition, 1 tree in 1 ward was repeated 3 times. On September 8th, 3 of the most colored fruits and 3 of the worst colored fruits were examined from each of the tested trees, and the average value was shown. In the evaluation of coloring, poorly colored fruits were represented by 1, and coloring considered to be ideal was represented by 5. The results are shown in Table 2.
