  Promoting the growth of plants is directly linked to increasing the production and quality of crops, and is extremely important for improving agricultural productivity.

  Therefore, attempts have been made to increase the yield and quality of agricultural products by treating plant growth promoters to promote crop growth.

  As a result of earnest research to solve the above-mentioned problems, the present inventors have obtained the knowledge that by using a specific fungicide, plant rooting is promoted and plant growth is promoted. Was completed. That is, the present invention relates to a plant growth promoting method characterized by treating a plant or soil with at least one compound selected from the group consisting of (a) fluazinam, (b) siazofamide, and (c) amisulbrom.

  The treatment of at least one compound selected from the group consisting of (a) fluazinam, (b) cyazofamide, and (c) amisulbrom of the present invention promotes rooting compared to the case where the compound is not treated. The effects of shortening the seedling period, increasing crop production, improving the quality of crops, and restoring the vigor of diseased trees at an early stage are brought about.

  Plant growth is promoted by treating an effective amount of the compound of the present invention with a plant, cultivated soil or hydroponic solution, promoting rooting of seeds, bulbs, etc., seedlings after planting, rooting of diseased crops. Is promoted. In addition, rooting promotion means an increase in rooting amount, an increase in root weight, and the like.

  Examples of treatment methods for plants include, for example, spray treatment on plant surfaces such as foliage, buds, flowers, ears, fruits, tree trunks, seed treatment (smearing, dressing, soaking, etc.), seedling treatment (irrigation, spraying, or Immersion), immersion treatment in bulbs, tubers, bulbs, roots, and the like, and hydroponics treatment such as mixing with hydroponics. The treatment may be the whole plant or a part thereof (stems and leaves, buds, flowers, ears, fruits, tree trunks, seeds, bulbs, tubers, bulbs, roots, etc.).

  As a treatment method to soil, for example, soil surface spraying treatment, mixing treatment after soil surface spraying, irrigation treatment, planting hole treatment, treatment between plant sources or strains (spraying or irrigation), cultivation soil, seedling box, seedling tray, The mixing process to the soil used for a paper pot or a nursery is mentioned.

  Examples of plants include gramineous crops (rice, wheat, barley, oats, rye, corn, etc.), cruciferous crops (cabbage, Chinese cabbage, radish, turnip, broccoli, cauliflower, navana, etc.), asteraceae crops (lettuce, Burdock, shungiku, etc.), solanaceous crops (potato, eggplant, tomato, pepper, etc.), cucurbits (cucumber, pumpkin, melon, watermelon, etc.), leek crops (eg, leek, leek, raccoon, garlic, etc.) Crop (celery, carrot, parsley, etc.), liliaceae (lily, tulip, asparagus, etc.), podaceae (buckwheat, etc.), legumes (soybean, kidney bean, azuki bean, etc.), convolvulaceae (sweet potato, etc.) Crops (spinach, sugar beet, etc.), grape crops (grape, etc.), rose crops (rose, strawberries, lily) Gore, pear, peach, loquat, almond, etc.) or mandarin orange crops (oranges, lemon, orange, etc.).

  Examples of the treatment period include various growth stages of plants (seeding period, germination period, seedling period, transplanting period, cutting time, growing period, flowering period, heading period, harvesting period, dormancy period). Crop, cruciferous, asteraceae, solanaceae, cucurbitaceae, leek, crops, liliaceae, scallops, legumes, legumes, convolvulaceae and rhesus The transplant period is more preferred. For grape crops, rose crops and citrus crops, the cutting, transplanting, growing or dormant periods are more suitable.
