Many people have doubts about plant growth regulators. In fact, plant growth regulators are a type of pesticide used to regulate plant growth and development. As long as they are used properly, they can greatly promote the healthy growth of crops. Let’s learn about the effects and key points of common plant growth regulators with the editor below.
Common plant growth regulators for plants include: aminoethyl ester (DA-6), chlorfenapyr, sodium nitrophenolate, brassinolide, and gibberellin.
- The following are the effects of various plant growth regulators
Extend the dormancy of storage organs: aminoethyl ester, chlorfenapyr, sodium nitrophenolate, brassinolide, sodium naphthaleneacetic acid, methyl naphthaleneacetate.
Break dormancy and promote germination: gibberellin, kinetin, aminoethyl ester, chlorfenapyr, sodium nitrophenolate, thiourea, chloroethanol, hydrogen peroxide.
Promote stem and leaf growth: gibberellin, aminoethyl ester, 6-benzylaminopurine, brassinolide, triacontanol.
Promote rooting: indolebutyric acid, naphthylacetic acid, 2,4-D, chlormequat, paclobutrazol, ethephon, 6-benzylaminopurine.
Inhibit the growth of stem and leaf buds: paclobutrazol, econazole, chlormequat, chlormequat, pix, triiodobenzoic acid, qingxiansu, fenxiuning.
Promote flower bud formation: ethephon, chlormequat, 6-benzylaminopurine, naphthylacetic acid, 2,4-D, chlormequat.
Inhibit flower bud formation: gibberellin, regulate phosphine.
Thinning flowers and fruits: naphthylacetic acid, carbaryl, ethephon, gibberellin, indole, 6-benzylaminopurine.
Preserve flowers and fruits: 2,4-D, aminoethyl hexadecene, chlormequat, sodium nitrophenolate, anti-drop agent, gibberellin, 6-benzylaminopurine.
Prolong flowering period: paclobutrazol, chlormequat, ethephon, chlormequat.
Induce female flowers: ethephon, naphthaleneacetic acid, indoleacetic acid, chlormequat.
Induce male flowers: gibberellin
Preserve cut flowers: aminoethylvinylglycine, aminooxyacetic acid, silver nitrate, silver thiosulfate.
Form seedless fruits: gibberellin, 2,4-D, anti-drop agent, naphthaleneacetic acid, 6-benzylaminopurine.
Promote fruit ripening: aminoethylaminopropionate, chlorfenapyr, sodium nitrophenolate, ethephon, bispyribac.
Delay fruit ripening: 2,4-D, gibberellin, bispyribac, kinetin, naphthaleneacetic acid, 6-benzylaminopurine.
Delay aging: 6-benzylaminopurine, gibberellin, 2,4-D, kinetin.
Increase amino acid content: paclobutrazol, anti-drop agent, indoleacetic acid.
Increase protein content: anti-drop agent, simazine, atrazine, naphthaleneacetic acid.
Increase sugar content: glyphosate, phosphine regulator, pix.
Promote fruit coloring: aminoethyl ester (DA-6), chlorfenapyr, sodium nitrophenolate, bis-nitropropene, indole ester, paclobutrazol.
Increase fat content: naphthaleneacetic acid, cyanogen, plasticizer.
Improve stress resistance: abscisic acid, paclobutrazol, bis-nitropropene, chlormequat.
- Key points for use
a. The dosage should be appropriate and should not be increased at will. Increasing the dosage or concentration at will will not only fail to promote plant growth, but will inhibit its growth, and even cause leaf deformity, dryness and shedding, and death of the whole plant.
b. Do not mix them at will. Whether plant growth regulators can be mixed with fertilizers, pesticides and other substances must be determined after carefully reading the instructions for use and testing, otherwise pesticide damage will occur due to improper mixing.
c. The method of use should be appropriate. When using, it must be diluted strictly according to the instructions for use.
d. Growth regulators cannot replace fertilizers. When you find that the plant is growing poorly, you should first strengthen the management of fertilization and watering, and then use growth regulators on this basis to effectively play their role.
The above is a summary of the functions and key points of use of common plant growth regulators. Do you have a better understanding of plant growth regulators? If you have any questions about agricultural fertilizers, you can leave a comment in the message area below.
