At the end of February, the 10th Plant Growth Regulator Development and Application Exchange Conference sponsored by China Pesticide Development and Application Association was held in Meishan, Sichuan. New developments, new achievements, and new needs are shared and exchanged. Participants believed that Plant Growth Regulators have unique effects, are safe and efficient, and have broad development prospects. They have obvious effects in increasing crop production, quality and efficiency, and can be called "legends" in the plant protection industry.
Plant growth regulators are an important part of pesticides and play an irreplaceable role in agricultural production. The healthy food, fresh vegetables, and brightly colored fruits we see are all due to it. First of all, plant growth regulators have a wide range of functions and can be called the "magic stone" of modern agriculture. Like animals, plants also have hormones that regulate their own growth and development, which participate in and affect the entire life process of plants from cell growth, division, rooting, germination, flowering, fruiting, maturation and harvesting. After studying and mastering their rules, people extract natural plant hormones from organisms for processing, and make chemical substances with similar physiological and biological effects to plant hormones, which are called plant growth regulators . There are many classifications of plant growth regulators with a wide range of effects. They can not only promote the growth of roots and stems and leaves, but also produce inhibitory effects. They can not only thin flowers and fruits, but also preserve flowers and fruits. They can even adjust crop plant type, control sex, break top dominance and improve fragrance and color . In addition, compared with pesticides such as herbicides, fungicides, and insecticides, the dosage of plant regulators is extremely low, and the amount of residues is also small. Just like the application of the natural plant growth regulator S-Abscisic Acid (abscisic acid) on grapes is a successful case of the effectiveness of plant regulators. As a "noble variety" among grapes, "Queen Nina" is plump and full of flavor, with an average selling price of more than 100 yuan per catty, showing huge market potential. However, in actual production, the problem of "unable to color" or "inconsistent coloring" has always troubled fruit farmers. Through precise regulation, S-antibodies can not only promote the coloring of grapes, but also increase the sugar content and further improve the quality of grapes. "In the past ten years, the research and development, promotion and application of plant conditioning products in my country have made great progress. The registered products have become more and more complete, and the crops used have become more and more extensive." Wang Fengle said, "As crops with high added value and high economic benefits With the increase of the planting area, agricultural production has higher and higher requirements for crop growth, fruit development, quality improvement and freshness preservation, so the requirements for plant regulators are higher and the demand is more urgent." "As an important science and technology of agricultural modernization, plant growth regulators can effectively regulate plant growth, ensure plant health, and stimulate plant vitality. They play an important role in stabilizing and increasing production, improving quality, enhancing resistance, and promoting chemical pesticide reduction and damage control. ". Wang Fengle, chief plant protection expert of the National Agricultural Technology Promotion Center, believes that. With the rapid development of plant growth regulators, the registration of plant growth regulator certificates has also entered a stage of great growth. Relevant data show that from 2021 to 2023, there will be a total of 295 newly registered plant growth regulators in my country, including 276 preparations, 19 original drugs, and 13 active ingredients. In 2022, the commodity volume and percent volume of plant growth regulator products used in the planting industry will increase by 23.57% and 16.8% respectively compared with the previous year.
