る場合もあり。<Conventional technology> Chlormequat is used in field crops such as wheat, potatoes, tomatoes, brocades, and husks, as well as hibiscus, azaleas, carnations, oleanders, wildflowers, geraniums, begonias, etc. Incesti Otsu As a growth regulator for ornamental plants such as Rose of Sharon, it mainly suppresses stem elongation and causes defects.
It is used to increase resistance to The method of use is to absorb it through the roots through soil irrigation,
There is a method of absorbing it from the foliage by spraying it on the foliage.
At the dyeing stand where foliage spraying was performed, the type of plant, previous growth history of the plant, weather conditions before and after spraying, other herbicides and insecticides, etc.
Mixed use with M agents, t or spray concentration may cause chlorosis in the sprayed crops, and extreme caution is required when spraying. Pest Control Standards, Herbicide Usage Standards, Plant Growth Regulator Usage Standards” Early Year 2nd Edition) <Problem to be Solved by the Invention> As mentioned above, when using a chlormate pot as a plant growth regulator, Although it is essential to take great care to prevent chlorosis from occurring in a single crop, the various factors involved in the j1 curse of chlorosis are not fully understood, and mulberry plants may be grown under inappropriate conditions. There may be cases where spraying is unavoidable.

ある。In addition, although it is necessary to suppress the growth of graves, cultivated plants that are difficult to use as chloromequat because they are prone to chlorosis (e.g., A. japonica, 100-day army, etc.)
There is also a method being invented that avoids chlorosis and still achieves stable and high effects.

The amount of water was applied to the foliage, and the degree of chemical damage (chlorosis) was measured 7 days later, and the plant height was measured 7 days later, and evaluated in the same manner as in Test Example 1.

あった。Thereafter, the plants were grown indoors, and the degree of chemical damage (chlorosis) was evaluated 7 days after spraying with chlormequat, the chlorophyll content was evaluated after 16 days, and the plant height and above-ground weight were evaluated after 25 days. The cultivation method was the same as in Test Example 1, but the chlorophyll content was measured using a commercially available chlorophyll tester (Fuji Heavy Industries Ltd.: WiCT-101), and the light transmittance of the second and third leaflets of the fourth compound leaf was measured. [1] The ratio to untreated leaves was calculated. The application date of chlormequat was 11 in all test plots.
It was the 16th of May, and supplementary night lighting of approximately 500,011x was provided for 4 days after spraying. The average temperature during the implementation period was 22°C.
〈発明の効果〉

生i11節作用を損なうことなく1作物に対する潜在的
な薬1!F(クロロシス)R生のおそれを回避すること
を可能にするものであり、以下のような効果を奏する。<Effects of the Invention> The present invention has demonstrated that chlormequat, which is a major plant regulator, can be used as a potential drug for one crop, without impairing its original action on the I11 node. This makes it possible to avoid the risk of F (chlorosis) R generation, and has the following effects.
