If you want your plants to stay healthy and strong, you need to use plant growth regulators. Plant growth regulators are chemicals that help plants grow in the right way and at the right pace. There are many different types of plant growth regulators, and each one is designed for a specific purpose. In this blog post, we will discuss the different types of plant growth regulators and how to use them properly!


Many beginning gardeners want their plants to grow quickly, be strong and beautiful. But if the soil is not fertile or other factors are present that slow the growth of grass, then in the end the gardener is disappointed and does not want to continue to care for the garden. But there is a way out and a solution to such a problem – plant growth regulators. This is only one factor that plant regulators help solve, but there is also a second factor – controlling especially rampant plants that need control or they will take over your entire vegetable garden or garden.

There are various plant regulators on the market that can inhibit their growth or, conversely, stimulate it. Below we will take a look at the properties that may be present in one or the other plant growth control product.

What do plant regulators do?

Simply put, plant growth regulators are chemicals that affect the rate of cell division and elongation in plants. In other words, they help plants grow! In addition, plant growth regulators can increase plant density and cause an increase in branching, which will greatly increase the volume of a particular plant.

But plant growth regulators can also have the opposite effect, that is, inhibit the development of a particular plant, cause it to bear less fruit, be thinner and less dense.Β Β 

Plant growth regulators that inhibit the development of plants and fruits

Groups of plant growth regulators that inhibit the development of plants and fruits are divided into groups. There are five in total:

  • Cytokinin – mainly used for thinning the fruit of trees and fruit bushes. This substance can work both ways, that is, in one case to inhibit the growth of fruit, in the other to activate. Everything will depend on the amount of the product, as well as the stage of its use on this or that plant;
  • Ethylene – stimulates fruit and leaf fall, and keeps shoots from being too long. It prevents lateral buds from developing, which significantly reduces fruiting. It is better than others at keeping ripe fruit on the trees and preventing them from becoming overripe;
  • Gibberellins – they enhance cell elongation growth, which in turn affects shoot retardation and puts the plant into a temporary dormant state. If the plant or fruit tree bears fruit, this substance will help improve the size of the existing fruits, but at the same time will not let them rot on the branches if you do not have time to harvest;
  • Absicinic acid is the best option for controlling plant shoots. It makes the buds and seeds dormant and regulates the water in the plants.

Plant growth regulators that speed up plant growth and help root plants

These rooting and growth enhancing products are divided into 4 groups:

  • Auxins – help develop the root system and also stimulate the growth of cambial cells that proliferate under the bark and skin of shoots;
  • Cytokinins – this substance actively affects dormant buds and helps stimulate them to develop faster. They also help to slow down the aging process of foliage;
  • Brassins – provide tone and immune system stimulation for flowers, vegetables and fruits. It helps to survive the shock of transplanting and also strengthens the seeds.

What are plant growth regulators?

Plant growth regulators (PGRs) are a group of chemicals that affect plant growth. They can be used to stimulate or inhibit growth, depending on the application. Plant growth regulators are often used in agriculture to improve crop yields, but they can also be used for home gardening purposes.

Are plant growth regulators dangerous?

A: No, plant growth regulators are not dangerous. They are safe to use and pose no threat to humans or animals. However, as with any chemical product, it is important to follow the instructions on the label carefully.

What are the benefits of using plant growth regulators?

There are many advantages to using plant growth regulators. They can be used to increase or decrease the growth rate depending on the needs of the plant. Plant growth regulators can also be used to improve the quality of fruits and vegetables and increase yields. They help free up extra time that you may have spent pruning leaves, branches.
