Instructions for the use of auxins in crop production, preparations based on them

Auxins are plant hormones that are considered to be indole derivatives. They are characterized by high physiological activity. With the help of products based on these substances, it is possible to activate the growth of fruits and shoots of crops. If the concentration of auxin in a plant decreases, its foliage begins to wilt. To prevent such problems, it is recommended to use special preparations made on the basis of auxins.

What effect do auxins have?

These substances are responsible for root growth and redistribution of beneficial elements in plants.Their distinctive feature is the ability to spread throughout tissues. This effect is achieved due to sap flow.

Substances provide apical dominance. This means that the shoot grows upward rather than bushes. In this case, the roots, on the contrary, grow downward. This helps them obtain moisture from the lower soil structures.

The most common auxin is heteroauxic acid. Chemists have learned to synthesize this substance artificially. Phytohormones take part in important processes. They help to get the following results:

1. Activate cell growth during active formation. This allows you to maintain the elasticity of the tissues. A deficiency of auxins is indicated by wilting of foliage.
2. Stimulate the formation of cambial tissue, which is located under the outer membranes. The cambium ensures the transfer of beneficial elements that are produced by the leaves and move to the roots.
3. Coordinate the interaction of different plant organs. This effect is achieved through the movement of phytohormones.
4. Accelerate the regrowth of hair-like roots. They help absorb useful elements from the soil. The formation of root shoots affects the survival rate of crops during planting and accelerates their growth after stress. These include prolonged precipitation, dry weather, high humidity, temperature fluctuations, the development of diseases and attacks by harmful insects.

Auxins do not belong to the category of fertilizers or plant protection products. At the same time, they have a pronounced auxiliary effect when fertilizing and treating crops against diseases and parasites.

What plants need them?

Such products are suitable for processing different crops. The positive effect is achieved depending on their type:

1. When processing fruit plants, it is possible to minimize the amount of carrion and improve the quality of the fruit. At the same time, auxins must be used in doses so that they do not deplete the soil.
2. Soaking beet, tomato or carrot seeds in a solution of auxins increases germination parameters and makes plants more resistant to attacks by parasites and the development of diseases.
3. Increased dosages of auxins help cope with weeds. At the same time, the substances do not harm cultivated plants.

Advantages and rules of application

The use of such substances in crop production has the following advantages:

• increasing the resistance of plants to unfavorable climatic conditions;
• strengthening the immunity of crops;
• full development of plants;
• high productivity;
• increasing the yield and quality of fruits;
• prevention of accumulation of harmful elements in all types of fruits, vegetables and berries;
• reducing the cost of fertilizers and expensive crop protection products.

Preparations based on phytohormones must be used correctly. An overdose of auxins slows down the growth processes of crops.

With the arrival of spring, the flowering of individual fruit trees may coincide with the onset of return frosts. As a result, flower buds freeze out without forming an ovary. To delay the blooming of flowers, plants need to be treated with a concentrated solution of auxin-based preparations. In this case, the substances inhibit important processes.

After using phytohormones, fruit trees freeze for a certain time. However, with the onset of favorable conditions, the development and flowering of crops resume again. This helps prevent crop losses.

Auxin-based preparations

Today there are many auxin-based products on sale. The most effective remedies in this category include:

1. "Kornevin" - promotes rooting of plants after planting seedlings of herbaceous crops, cuttings, seedlings of tree species during vegetative propagation. With its help, it is possible to activate the growth of young shoots. In addition, the substance allows you to minimize the negative impact of stress factors.
2. "Heteroauxin" - used in the same way as "Kornevin". A distinctive feature of this remedy is its faster effect. However, it lasts less.
3. "Kelpak" is a systemic growth regulator. It includes 7 varieties of auxins. In addition, the composition contains 12 types of other plant phytohormones. This helps achieve a combined effect on crops.
4. "Gulliver" is a combined remedy. It contains phytohormones and succinic acid.

Security measures

To ensure that auxin-based preparations do not cause harm to the body, safety rules must be followed when using them. When working with products, you need to wear personal protective equipment - goggles, a respirator, gloves.

Compatibility

Auxin-based products can be combined with many fungicides and insecticidal preparations. To assess compatibility, you need to mix 2 products in small volumes. If sediment or flakes appear, it is better to refuse to use the composition.

Auxins are effective plant hormones that activate growth processes. In order for drugs based on such drugs to have an effect, they must be used according to the instructions.
