Types of growth stimulants for plants, the best preparations and their use

Plant growth stimulants have become frequently used agricultural products. They accelerate the growth and development of agricultural crops, help the formation of buds and ovaries, and improve the appearance and quality of fruits. Let's look at how growth stimulants work, their types and classification, when and how to use them according to instructions, and safety measures.

How do plant growth stimulants work?

The basis of growth biostimulants is plant hormones. In nature, they are produced by the plants themselves, but in this case they are obtained synthetically. Crops are treated with stimulants before planting and during the growing season, as well as during the period when fruits ripen.

Biostimulants act in a complex manner:

• help form the root system;
• enhance growth;
• stimulate the laying of more buds;
• make flowering more magnificent;
• help plants form and maintain ovaries;
• increase the size, weight and volume of the fruit;
• restore plants after diseases or damage by pests.

Growth stimulants are used in conjunction with microfertilizers and protective agents. With the correct dosages of all drugs, the overall effect is enhanced.

Classification and types

Growth promoting drugs are divided into 2 groups: organic and synthetic. Despite their different origins, they act in the same way: they activate the physiological processes occurring in plants, accelerate growth processes, promote abundant flowering, and improve fruiting.

Auxins

These are phytohormones with a wide range of action. Stimulates the development of roots and rhizomes, the growth of the number of cells of the cambial layer. Accelerates the growth and ripening of fruits.

"Heteroauxin"

Stimulates the formation and growth of roots in seedlings, tubers, bulbs, seedlings. Available in capsules and tablets of 0.1 g. Soak the material (tubers and bulbs) in the solution for a day, the roots of seedlings, seedlings - for 3-4 hours, green cuttings - for 10-16 hours, lignified ones - for 16-20 hours. Dosage: 1 or 2 tablets per 10 liters for cuttings, for vegetables, trees, seedlings - 1-2 tablets. for 2 l.

"Kornevin" and "Ukorenit"

The drugs are used in solution and dry form. In the first case, the material is soaked in a solution (dissolve 1 g in 1 liter), in the second, it is powdered before planting - for 25-50 pieces. 5 g of cuttings are consumed. After 10 days, the already planted plants are re-watered. The period of influence of the stimulant is long - 20-60 days.

Gibberellins

Phytohormones that promote cell growth and division therefore stimulate the growth of stems and vines. They also stimulate germination and flowering, setting, prevent the aging of leaves, their effect is similar to that of auxins.

"Gibberellin"

Plants are sprayed with the solution at different periods of their growing season. Preparation procedure: dissolve 0.3 g of stimulant in 6 ml of alcohol, mix the solution with 2-6 liters of water. Spray fruit trees, strawberries, grapes when they bloom and after the formation of the ovary. After treatment, you can expect the fruits to ripen 1.5-2 weeks earlier, and the yield to almost double.

"Gibbersib"

The stimulant is used on tomatoes, cabbage, cucumbers, and potatoes. Spray 2-3 times during flowering to increase yield (up to 20%) and reduce the duration of fruit ripening and reduce disease incidence. When spraying grape bushes at a dose of 0.9-1.2 kg/ha, the yield increases by 30-40%.

"Gibberross"

Spray wheat, tomato, garlic, potatoes, cucumber, cabbage, alfalfa, onions, eggplant, lettuce, peppers, pumpkin, peas, beans, apple trees and grapes. Processing increases yield, weight of fruits and grains, they ripen faster, and taste improves. Plants are better able to resist diseases, cold or, conversely, heat.

"Gibbor-M"

The growth stimulator is used on grapes, legumes, vegetables, potatoes and cabbage.Sprayed in different phases of development to form and preserve ovaries, resistance to diseases and bad weather, accelerate ripening, increase the number and weight of fruits and berries.

"Ovary"

Used on vegetable and legume crops grown in beds and in greenhouse conditions. Allows you to stimulate the setting, and then the growth of grains and fruits. Strengthens the protective forces of plants, increases early and overall yield by a third, the fruits ripen a week ahead of schedule.

"Bud"

Due to the stimulation of fruit set and the prevention of its shedding, the drug increases the volume of the harvest by 20-37%, accelerates ripening by a week, improves the characteristics of the fruit, they become tastier, larger, and contain more vitamins and sugars. The plants themselves become resistant to drought and cold, recover better after them, seedlings and seedlings take root faster, and seeds germinate faster.

"Tomaton"

Growth stimulator for tomatoes grown in beds and greenhouses. Works effectively on tomatoes of any variety. Like other means of similar action, it stimulates the ovary and reduces its abscission. Tomatoes ripen faster, the first harvest increases by 50-100%, and its total volume by 24-50%.

Cytokinins

Hormones that stimulate the transport of nutrients into the cell, regulating cell division, maturation of chloroplasts, growth of lateral roots and additional buds. Slow down the natural aging of cells.

Cytokinin paste

Contains phytohormones and vitamins, awakens dormant buds, stimulates the formation of new ones, the germination of peduncles and the laying of “babies”. Used on indoor flowers and ornamental plants to activate flowering and reproduction.

Keikigrow Plus

This is a Canadian made paste. It is expensive and has a small volume, but this is justified by its effectiveness. It is applied pointwise to areas of the plant that are not developing. Accelerates metabolism at these points, stimulates dormant buds, and prevents the death of shoots and leaves.

"Cytodef"

Restores plants after stress, stabilizes protein synthesis, increases resistance to soil drying out. Normalizes phytosynthesis during cold weather, promotes the accumulation of carbohydrates, thereby increasing the level of frost resistance.

Brassins or brassinosteroids

Hormones make seedlings thicker and taller, increase the size of above-ground parts, including fruits, and stop the aging of leaves and their falling off. Strengthens plants, making them less susceptible to weather conditions.

"Epin"

Provides rapid germination, rooting of seedlings and seedlings after picking or transplanting. Increases resistance to cold, bacterial infections and fungi. Restores weakened and old plants by stimulating the growth of lateral shoots. Reduces the level of heavy metals and nitrates in fruits, shortens their ripening time.

"Epin Extra"

It has a similar effect and purpose, but the hormone content in it is an order of magnitude lower. However, this does not affect the effectiveness of the drug.

In what cases is it used?

Plants can be treated with growth stimulants at the stage of seeds, seedlings, shoots, or at any stage of the growing season when necessary. The activator solution is applied to the surface by spraying or under the root when watering. Stimulants are added to liquid for hydroponic systems in order to speed up the processes of growth and development.

Instructions for use

Most agricultural preparations with hormones are available in liquid form. The concentrate is diluted in water in a certain dosage. Plants are sprayed with ordinary sprayers.

Since stimulants contain plant substances, they do not have a long shelf life. After its expiration, it is not recommended to use the drugs. The finished solution is not stored for longer than 1 day, as it quickly loses its beneficial effect.

Security measures

Growth enhancers are not as toxic as pesticides and belong to hazard class 4 agricultural products. This means that poisoning with them is infrequent, but you still need to work with them using personal protective equipment. It is worth wearing rubber household gloves, a respirator and goggles to protect your face and hands from possible contact with drugs. When dissolving the powder and processing, do not smoke, eat or drink. After the work is completed, you should definitely wash your face and hands with soap.

The products can be dangerous for the inhabitants of reservoirs and rivers, so you should refrain from using them if the site is located near water sources or fish farms.

Growth stimulants are a special group of agrochemical preparations that have a stimulating effect on the growth and development of crops. In addition to normalizing or regulating growth processes, it has a supporting and restorative effect after damage or stress. Improves fruit set, quality and extends the shelf life of the harvested crop.

Growth stimulants are not fertilizers or protective drugs; using them, you cannot do without specialized means. But they are good helpers if used together with fertilizers and pesticides.In addition, you need to timely and properly care for the plants and provide them with complete care. Taken together, all means and agricultural techniques will give the long-awaited result in the form of a rich harvest.
