Description

Plant growth regulator and method of use thereof

The present invention relates to a growth regulator for a plant of the family of the genus Asparagus, and a method for using the same, and provides an increase in the amount of harvesting and the number of leaves of the plant, especially the banana, and a new pseudo-stem (sub-strain) An agent excellent in plant growth regulation effect such as growth promotion (hypertrophy).

A cultivated plant belonging to the genus Musa, especially a banana, is a general term for a group of edible fruits, and is referred to as a fruit. The plant is mainly cultivated in East Asia such as China and Taiwan, Southeast Asia such as the Philippines, Indonesia, Thailand, Vietnam, West Asia such as India, Brazil, Ecuador, Costa Rica, Mexico, Guatemala, Colombia, Peru and other Central and South America. In Africa, such as Tanzania, Congo, Uganda, and South Africa, plantations are also cultivated and cultivated throughout the year. Bananas cultivated and harvested in these countries are exported to all parts of the world.

In the case of banana cultivation, the root portion of the stem is underground, and the part of the stem that protrudes high above the ground is called a pseudo stem, which is actually formed by overlapping several layers of sheaths, from the pseudo stem. The long elliptical leaf (leaf body) grows at the front end, and further extends from the front end of the pseudo stem to the fruit shaft. At the front end of the fruit shaft, a whole room including the fruit finger and the fruit house is formed, and the banana grows in the whole room. After harvesting the banana, the pseudo stem portion (parent plant) was cut at 2 meters from the ground. In this case, the new pseudo-stems (sub-plants) newly grown from the roots of the underground are propagated in the same manner, or the operation of "dividing the new pseudo-stems (sub-plants) and cultivating them, and then harvesting the bananas" is repeated. When cultivating a banana, how many leaves (functional leaves) remain is important because of the last leaf It takes 3 months to withdraw (before flowering) to harvest, and at least 12 to 13 functional leaves must remain during flowering. If the number of functional leaves is insufficient, the plants will be cut down during the cultivation.

In the case of banana cultivation, although the increase in harvest is the most important issue by the control of pests and diseases, the prior art requires a lot of labor due to the multiple treatments, and further, the drug-resistant bacteria or the drug-resistant pests. Appearing makes it more difficult to control. On the other hand, the use of a drug (plant growth regulator) such as a growth promoting effect of a crop is also used to grow bananas in a healthy manner, and attempts to increase the amount of harvest.

It is a compound of the active ingredient of the plant growth regulator of the present invention (general name: Isoprothiolane, chemical name: diisopropyl 1, 1,3-dithiolan-2-ylmalonate (diisopropyl 1, 3-dithiolan-2-ylidenemalonate)), which is a plant disease control agent, and is sold as a rice blast disease control agent, and is sold under the trade name "Fujiwan", which is a known compound (see, for example, Non-Patent Document 1). . In addition, a method of applying a drug containing as an active ingredient to the surface of the soil or mixing with the soil to help the growth of plants other than rice (see Patent Document 1) is disclosed, and the use of Ascots as an active ingredient is similarly disclosed. A method of growing a plant which acts on the root of a plant to promote the growth of the plant and enhance its vitality (see Patent Document 2). However, it is unknown that the genus can be used as a plant growth regulator for musa plants, especially bananas, and it is completely unknown that the compound is increased in the amount of bananas and the number of leaves, and the growth of new pseudo-stems (sub-strains) is promoted (hypertrophy). ) and so on.
