New tests carried out by Adler Agro demonstrate the efficacy of Brotostim and Root products in tomato cultivation. Specifically, in a trial conducted in a seed company, the height and weight of the plant were evaluated in trays treated with Root and Brotostim against other untreated trays. Our products increased the weight of the plant by more than 22% and the height of the plant by more than 37%.
Repilo is one of the most common and important fungal diseases in the olive grove. The main symptom of the disease is circular brown spots on the leaves, accompanied by defoliation, which weakens the crop and impairs production.
But first let's take a closer look at what the Repilo is.
The fungus that causes this disease is called Cycloconium oleaginum. The most frequent periods of infection of the disease are in spring and autumn, since the most favorable conditions for its spread are humidity and temperatures between 8 and 24 ºC.
The evolutionary cycle of the Repilo is divided into four phases:
Germination: the fungus germinates on the leaf in the presence of free water and temperatures around 20ºC.
Infection: the first infections coincide with the rainy season in late summer or early fall, when the disease initially develops.
Sporulation: conidia that will spread the disease appear on the outside of the leaves. This is the time when the typical spots will appear on the leaves.
Dissemination: conidia are mainly dispersed by rain, although they can also be carried by the wind. For this reason, the times of greatest spread of the disease take place in spring and autumn.
The fungus survives in unfavorable periods (summer and winter) on fallen leaves or on those that are kept on the tree, where it can remain dormant for several months.
Prevention is the best control method in the fight against repilo. In the months after harvest, selective pruning is essential to promote aeration.
In addition, in areas that favor the appearance of the disease (such as in mountainous areas, near rivers, areas prone to dew, etc.), applications with products based mainly on copper oxychloride or cuprous oxide are advisable.
In cases where the disease is already present, Adler Agro recommends accompanying phytosanitary treatments with Biactive.
Biactive is a biostimulant based on algae extract and microelements specially formulated to help overcome adverse situations such as periods with lack of water, attacks by pathogens, etc. In addition, it can be mixed with other phytosanitary products.
Overview of amino acids
The amino acid is an organic molecule composed of carbon, hydrogen, oxygen and nitrogen. When a series of amino acids are joined by peptide bonds, the proteins are formed. Proteins are important macromolecules involved in all aspects of growth and development of plants.
Plants synthesize amino acids from the N absorbed as nitrate or ammonium that is in the soil. Clearly, the process of absorbing nitrogen from the soil is an important loss of energy for the plant. Therefore, the main reason why it is so important to applicate these products in agriculture is the energy savings that they achieve. This energy will be used in other processes such as sprouting, flowering or fruit set and fruit fattening, so that will increase the quality and the production of the crop.
Types
There are 20 types of amino acids that form proteins. There are certain types that are better for specific functions. Thus, the amino acids responsible for chlorophyll synthesis are Alanine, Arginine and Glycine. For the development of the root or to delay the senescence there are the Arginine and the Methionine. If we want to achieve a chelating effect on the soil and a better development of shoots and leaves we will use the Glycine. For the resistance systems of the plant the best types are the lysine, the glutamic acid and the glycine. Finally, for the synthesis of gibberellins we will use leucine and proline.
Aminograms, what they are and how they are interpreted
An aminogram is a schematic representation of the amino acid composition of a peptide or protein (or in our case of a fertilizer). A aminogram can be qualitative (if only appears the different types of amino acids that contains the product) or quantitative (if also appears the amount of each amino acid).
Fertilizer companies use this diagram to give information about the amino acid content of the products. In addition, we bring also the amount of free amino acids in our products. This data provides very important information about the product quality. In the hydrolysis (process by amino acids are obtained, and that will be discussed later) peptide bonds of proteins are broken, generating fractions of amino acids. These portions can be very heterogeneous, but only amino acids that are free can be absorbed by the plant, so this is one of the factors for evaluating the quality of a product.
Sources and methods of extraction
The main sources of amino acids are from vegetables, animals or synthetics. Amino acids of animal origin are usually produced from collagen and hair. Those obtained by plants, are extracted from vegetable waste of soybean, cereals, etc. The aminograms presented by these types of products depend on the type of plant material used. Finally, it is possible to design a product with synthetic amino acids, that is, to buy specific amino acids in the chemical industry and make a product with the amount of each you want. This method is much more expensive, but the resulting products are of high quality and have a faster effect.
In agriculture they are mainly two types to obtain the amino acids. Acid hydrolysis and enzymatic hydrolysis (or enzymatic fermentation).
Acid hydrolysis is the most rudimentary method and cheap. It consists in a prolonged boiling of the protein with acid solutions. This method is quite aggressive, so the resulting amino acid have low quality, due to there is a high percentage not free amino acids, and some are partially destroyed during the process. However, the improvement in manufacturing and the new techniques have managed to increase the quality of these products.
The enzymatic fermentation process is similar to the previous one, but much less aggressive. It is not necessary to increase a lot the temperature and instead of an acid solution, a certain enzyme is used (usually of bacterial or fungal origin). The process is more expensive and complex, but the percentage of free amino acids is much higher, so most of the composition of these products is usable by the plant.
Conclusions
The use of amino acids in agriculture is a tool that can be very useful to improve the production and the quality of the crop to overcome moments of stress due to low temperatures, droughts, etc., but it is necessary to have a knowledge of this type of products to buy the correct item for your crop.
In ADLER AGRO there is a variety of products with amino acids. It will be pleasure to answer the questions that can arise about which of our products is the best one in each case.
Crops frequently suffer from deficiencies of certain nutrients such as Ca, Fe, Zn and Mn, as they are scarcely available due to pH or soil type. Therefore, when carrying out the nutritional program of the crop, the basic fertilization of NPK should be complemented with a contribution of microelements to ensure that we maintain the optimum levels of these nutrients and thus we cover all the needs of the plants.
The amino acids also promote growth and help overcome stress situations of the crop thanks to its powerful biostimulating effect. They also allow nutrients to be absorbed quickly and efficiently by plants.
Adler Agro completes its line of amino acids with a new range of micro and macroelements complexed with vegetable amino acids for foliar application. In order to prevent and correct deficiencies in all types of crops, improving absorption and translocation, and thus helping the plant to overcome any type of lack or stress.
ADLER AGRO presents our new package for powder products, specially created for the chelates line.
This new design, apart from looking for an improvement of the image and the user comfort, it reflects the commitment of ADLER AGRO for optimizing the transport and reducing as far as possible the use of materials for packaging.
This way we offer more sustainable and competitive solutions to our customers without modifying the quality of our products.
BRIX is a special fertilizer that increase the sugar content of the fruit. BRIX is effective in crops such as melon, grapes, etc., in which the sugar content is important for subsequent commercialization. The product is also especially useful in early varieties, in which the sugar content could be lower. So, with the help of our product BRIX, we can increase the quality of the fruit.
Recently, the technical department of Adler Agro has successfully carried out new trials with BRIX in the cultivation of orange trees. The tests were carried out during the months of December and January in the municipality of Benaguasil (Valencia). These tests demonstrate the effectiveness of our product BRIX, which increases the sugar content in treated oranges.
