Gibberellic acids are considered the active ingredients in many pesticides that act as plant growth regulators. These products are designed to increase seed germination, stimulate root development, and enhance growth processes. They also increase crop yields and improve the quality of finished products.
Description of the substance
This substance is a plant hormone. Gibberellic acid is an effective stimulator of crop growth and development. It is considered an analogue of the plant hormones auxins. These substances were discovered by the Japanese researcher Yabuta back in 1935. Today, more than 60 types of these substances are known. They are present in pathogenic fungi of the species Gibbtrella fujikuroi. For this reason, the acids are often called Gibberellaceae.
These products are produced as white or yellowish crystals. They are odorless and tasteless and dissolve poorly in water and many organic substances. However, they mix well with alcohol and acetone.
The drug is available in ampoules packaged in foil pouches, as tablets with a 20% active ingredient content, and as a concentrated paste. A ready-to-use 78% alcohol solution is also available commercially. It is sold in 5-milligram ampoules.
Purpose
Gibberellic acids are most often used to treat seeds. These substances increase their germination rate. These agents can also influence the sex of crops.
In addition, the use of gibberellic acids helps to achieve the following results:
- preserve the ovary - it will not fall off even in unfavorable climatic conditions;
- improve flowering and activate fruit development;
- improve the appearance of the crop;
- extend the shelf life of harvested fruits.
These substances are suitable for treating ornamental crops. For the products to achieve the desired effect, it is important to properly care for the plants and follow agricultural practices. The product can be used regularly. It has no toxic effect on crops.
Terms of Use
To apply gibberellic acids, foliar spraying is recommended. A fine mist spray is recommended. It's important to avoid dripping. To apply, mix 1 milliliter of the product with 1 liter of distilled water.
The easiest way is to use ampoules containing a pre-mixed alcohol solution of the medication. To do this, follow these steps:
- shake the ampoule before opening;
- pour some distilled water into the container and pour the contents of the ampoule into it;
- Mix the ingredients well and add water to obtain 4-5 liters of the product;
- Mix the ingredients again.
When using the crystal form of the product, first dissolve it in 6-7 milliliters of ethyl alcohol and shake until a homogeneous solution is obtained. Once the crystals have dissolved, add the mixture to distilled water.
A syringe can be used to measure out the required amount of stock solution. It's important to strictly adhere to the dosage and not exceed the concentration.
Gibberellic acids can be applied in various ways: soaking seeds, spraying plants, or dipping inflorescences in the solution. Treatment of the above-ground parts is done to increase foliage or inflorescences. This procedure also promotes fruit growth. It is recommended to apply the solution to plants in cloudy weather, with the temperature at 16-18 degrees Celsius.
Safety precautions
The product is considered completely safe and does not cause any adverse health effects. Experts recommend wearing rubber gloves during handling.
How to care for crops after application
