It is accepted in organic farming and acts as an herbicide, fungicide, and repellent.
It is an inexpensive and relatively effective product, as well as being used to control some pests and diseases.
Its use is quite varied and is not limited to preventing the growth of pests and diseases; it is also used to correct soils with a basic pH (above 7).
1 kg of sulfur per square meter is able to reduce the pH of a soil by 1 unit.
In relation to Pests and diseases, Its use is accepted to treat oidium/oidiopsis, red spider, eriphidous fungi, mites, erinosis, etc.
Its use is permitted provided that it is not mixed with oils or alkaline-reacting products. In case of doubt, consult before use.
MODE OF ACTION
  • The cells of fungi are permeable to sulfur, which in the cytoplasm affects the mitochondrial respiratory chain.
  • There may be a transfer of hydrogen ions to sulfur, instead of a transfer to oxygen, producing toxic hydrogen sulfide.
  • Sulfur can rapidly oxidize protein and non-protein sulfhydryl groups.
  • This phenomenon can alter the flow of electrons in the respiratory chain and, consequently, oxidative phosphorylation, resulting in fungotoxicity.
  • A plant defense mechanism against pathogens is the release of hydrogen sulfide. The accumulation of sulfur may be associated with a hypersensitivity response of the plant to the pathogen, controlled by the expression of many genes.
  • The sulfur applied to the leaf can be absorbed and metabolized acting as a defense agent against pathogens, or it can be converted into sulfate or other sulfur compounds.
CONDITIONS FOR APPLYING AZOFOS FOR CULTIVATION

Like any phytosanitary product, sulfur also requires certain application standards and has certain requirements, which are discussed below:

  • Do not apply at high temperatures.
  • It should not be mixed with oils or alkaline reaction elements.
  • It does not apply to crops whose fruits are intended for canning.
  • It should not be applied on artichokes or varieties of sensitive fruit trees (pears, apricots or apples, for example)

However, it is a product that is not very comfortable to use, at least when it is in a solid form (powder). We find it as a powder for dusting, which means that if we are not very careful, we will end up losing a lot of sulfur; furthermore, it can be irritating.

CAUTION WITH HIGH TEMPERATURES

A mistake that many farmers often make (and quite often) due to ignorance is applying sulfur to their crops when temperatures are high. Although the technician advises them not to do so, many choose to proceed, with the risk it poses to their plants.

Why?

The range of action of sulfur is very limited by temperature, especially as a fungicide. It acts from 20 ºC and causes many problems when the thermometer exceeds 30 ºC.

When temperatures are very high, above 30-35 ºC, the sulfur dust goes into a gaseous state, mainly because the dust is very fine and enters through the plant’s pores, known as stomata, which are located on the epidermis of the plants (especially on the underside of the leaves). Inside the plant, it absorbs oxygen and turns into SO2 (Sulfur dioxide).

Depending on the humidity conditions inside the plant, it oxidizes and turns into SO3 (sulfur trioxide).

Sulfur trioxide is a corrosive substance considered a hazardous substance, when the sulfur trioxide that is found inside the plant absorbs moisture (water), a very interesting chemical modification occurs:

H2O + SO3 = H2SO4
It is sulfuric acid


A substance that is capable of be corrosive to the Organic tissue, whether vegetal or animal. An acid rain is produced inside the plant, without the plant knowing it.

Photosynthetically active radiation – equal weighting of all wavelengths between 400 and 700 nm
DLI
Integral of daylight (of photosynthetically active radiation)
PPFD
Density of the flow of photosynthetic photons on a surface

What light plants need: Active Photosynthetic Radiation (APR)
Plants and humans perceive light very differently from each other. Humans and many other animals use something called photopic vision in well-lit conditions to perceive color and light. Lumens are a unit of measurement based on a model of human eye sensitivity under well-lit conditions, so the model is called the photopic response curve.
 
It is well known that most of photosynthesis is stimulated by light that is in the spectral range between 400 and 700 nm, roughly the visible part of the light spectrum. This is exactly what the photosynthetically active radiation says: All photons that enter this range are counted equally. Light outside this range has no meaning for the PAR metric.
The graph clearly shows why lumen values are hardly suitable as a reference point for plant lighting.
How much light do plants need: Full-day light – DLI

The required intensity is derived from the total light needs of the plant during the day. An index for the different light requirements is the diurnal light integral, called DLI (Daily Light Integral). It describes how many photons reach a certain area in 24 hours.

For several species of plants, it is known how much light they need or can sensibly use over the course of a day.

Calculation of the DLI

PPFD in µmol/m²s [number of photons per second per m²]. * 3600 [Number of seconds in an hour] * t(h) [Number of light hours in a day] / 1,000,000 = DLI in mol per day

What actually reaches the plants – PPFD

These theoretical values are very good for determining what a light source emits in photons and how efficiently it works. What, in turn, reaches the plants cannot be determined using theoretical values, but depends on the individual use scenario.

The so-called photosynthetic photon flux density (PPFD) indicates how many photons from the PAR region impact one square meter. This should be based on the needs of the plants (see DLI) and the goal should be to achieve the most uniform distribution possible.

]]> THE BERRIES INDUSTRY IN MEXICO https://www.grupotextiles.com/en/the-berry-industry-in-mexico/ Wed, 17 Aug 2022 16:58:55 +0000 https://www.grupotextiles.com/?p=32078 The industry has more than 27 years of history and is currently positioned as one of the most important businesses in Mexico, as it represents the third most exported agricultural product after beer and the export of Mexican avocados. The export of berries in Mexico is valued at 400 million dollars, exporting 364 thousand tons worldwide.

The impulses facilitated by the Mexican government and specialized organizations in berry cultivation in Mexico have achieved great results in the country globally, as Mexico has been able to position itself as the fourth world exporter of strawberries.

The blueberry and raspberry are considered the berries with the greatest growth potential for the next 10 years.

Who are the main producers of berries in Mexico??

The producing states in Mexico with the highest participation are Michoacán, Jalisco, Guanajuato and Baja California.
In fact, the state of Michoacán had a berry production of more than one million dAnd tons of strawberries, raspberries, currants and blueberries, which helped put Mexico as the third world power in the production of red fruits. The berries in Mexico are produced in 32 Michoacan municipalities, among which are: Zamora, Jacona, Los Reyes, Panindícuaro, Maravatío, Vista Hermosa, Ixtlán and Tangancícuaro.

This continues to position Michoacán as the leading producer of berries in Mexico, as well as being the world leader in the production of persimmons, with 94% of the national harvest of strawberries. It also ranks first in strawberry production nationwide, contributing more than 70% of the berries in Mexico.

What is the current demand for berries in Mexico?

Of the berry production mentioned above, 97% of the exports of berries are to the United States and Canada, the rest between Europe and Asia. The annual sale of berries is around 2.3 billion dollars. This is the economic importance of berries in Mexico, since according to the president of the National Association of Berry Exports, José Luis Bustamente Fernández, the berry industry in Mexico generates around 420,000 direct jobs.

In addition, its profitability index is higher than that of products such as sugar cane or corn production in Mexico. The benefit-cost ratio of berries in Mexico determines their financial viability in a productive project. According to the Mexican Journal of Agricultural Sciences, this ratio is 2.82% for the case of blueberry, 1.88% for the raspberry, 1.82% for the strawberry, and 1.76% for the pomegranate. Sugar cane has a benefit of 1.5% and corn of 1.2%.

Although the berry market in Mexico is primarily aimed at North America, shipments to the Far East have increased by about 5%.
]]> What are the Afidos? https://www.grupotextiles.com/en/which-are-the-aphids/ Wed, 10 Aug 2022 15:43:07 +0000 https://www.grupotextiles.com/?p=32039 Aphids are one of the most common insect pests in garden plants, from vegetables to roses. Each species of aphid generally attacks the same family of plants, but multiple species of aphids can coexist in the same garden. Aphids can reproduce without mating, so their numbers can increase dramatically in just a few days. And they also feed in dense clusters, making them one of the most destructive plant-devouring insects.

IDENTIFICATION

Aphids have a smooth, teardrop-shaped body and can have various colors depending on the species, such as green, orange-yellow, black, or reddish pink. They often have a waxy or waxy appearance, and generally the adults do not have wings. Unlike other similar insects, aphids move slowly when disturbed.

SIGNS / DAMAGES

Aphids damage plants by piercing them with their mouth and sucking the plant juices. They often attack young and tender parts such as soft stems and leaves or new buds. The plants become wrinkled, curled and folded and their growth is stunted. Another sign of problems with aphids is the presence of black mold like soot that forms in the honeydew excreted by the aphids when feeding. Aphids can transmit viruses from one plant to another.

]]> Damage caused by the hail in crops https://www.grupotextiles.com/en/we-are-suffering-from-the-hail-in-our-crops/ Tue, 26 Jul 2022 15:59:44 +0000 https://www.grupotextiles.com/?p=31971 If rain is your plants' best ally, hail is definitely their worst enemy. During the rainy season, the chance of witnessing this meteorological phenomenon increases significantly, so it's important to know how to protect them so that they don't get damaged after a storm.

Hail is a hydrometeorite, composed of particles of water in solid state (i.e., frozen, made into ice) that can be spherical, smooth-surfaced or irregular. Its size can vary between 5 mm and 12 cm but there have been cases where it has reached 20 cm.

The damage caused by hail on crops can be slight breaks in the leaves or small bruises on the fruits, until they completely destroy the crop. Therefore, plants that have minor damage do not devote themselves to growing; they remain in the generative period, especially dedicated to trying to heal their wounds, completely forgetting about growing.


To counteract the damage, different types of applications are made depending on the damage caused by the hail:

+ Application of secants
+ Fungicides
+ Leaf nutrients or amino acids that would be responsible for preventing problems in the crop, such as helping to improve damage a little faster without having such large economic losses.

What is being sought is for the plant to heal its wounds more quickly, and for damaged tissues to recover, thereby preventing fungal problems and resuming plant growth.
As a recommendation regarding applications and methods of improving the crop due to hail damage, I leave you the following points.

How to protect your plants of the hail?

+ If what you want is to protect the roots, you can place piles of dry leaves or stones, which will cushion the impact of the hail.

+ LSince meshes are a great option for protecting the upper part of the plant and the fruits, in this case the Reinforced anti-rain mesh It is the best option for this type of cases.

ANTIGRANIZO REFORCED

SOMBRA LENO GV 8%, 11%, 16%,18% and 20%

The mesh with reinforcements in its structure is used to protect crops from damage caused by hail impact and prevents burns from excessive impact by the infrared light of the sun. They are generally used in apple trees, berries and pears.
]]> MEXICO 6TH PLACE IN PROTECTED AGRICULTURE https://www.grupotextiles.com/en/mexico-6th-place-in-protected-agriculture/ Wed, 20 Jul 2022 19:01:12 +0000 https://www.grupotextiles.com/?p=31937 Currently, Mexico ranks sixth worldwide in protected agriculture; among the crops most produced under this system are red tomatoes, strawberries, cucumbers, chili peppers, raspberries, blueberries, and roses.

According to the United Nations (UN), in 2019 around 70% crops were lost in Central America due to extreme weather phenomena, and drought affected 60% of Mexican territory, which limited the development of agriculture.
Given these circumstances, protected agriculture is becoming increasingly important as an accessible option for protecting crops from environmental changes.
Currently, Mexico produces 50 percent of its crops through protected horticulture and the other 50 percent in open fields.
The protected agriculture industry exports more than 3.2 million tons annually with a commercial value exceeding 3 billion dollars, according to the Mexican Association of Protected Horticulture A.C. (AMHPAC).
This means that a surface of 46,709 hectares nationwide is occupied by greenhouses, macro tunnels and shade netting, according to the System of Information on Agro-Food Products for Consultation (SIACON).
The growth of protected agriculture has been exponential, going from just 700 hectares (has) to 23,250 has between 2000 and 2015, according to the Service of Agro-Food and Fisheries Information (SIAP).

 

This indicates that 60 percent of the production in greenhouses is destined for export and 70 percent corresponds to tomatoes. The technological level of the greenhouses also varies, ranging from rustic to the most sophisticated with state-of-the-art technology that uses computer systems to control temperature, humidity, and irrigation. As a comparison, open field production is around 40 tons per hectare, whereas in Protected Agriculture, 300 tons per hectare are obtained, in the case of tomatoes and/or jitomates. This crop is the main vegetable produced under this scheme; five out of every 10 facilities are dedicated to this vegetable.

The use that habanero pepper can have is diverse. First of all, because it is an important ingredient or seasoning in the diet of many regions, as is the case in the states of the Mexican peninsula (Yucatán, Campeche and Quintana Roo), where many of the dishes typical of the region include it.

It has also gained great importance in the pharmaceutical industry due to the presence of capsaicinoids, which determine the degree of itchiness in the fruits of the genus Capsicum, which can stimulate appetite, increase nasal, lacrimal and gastric juice secretion, as well as have analgesic, anti-inflammatory and anti-irritant effects.

]]> TOMATO PRODUCTION DEPENDING ON TODAY'S BPA LEVELS https://www.grupotextiles.com/en/tomato-production-tied-to-todays-bpa/ Thu, 29 Apr 2021 16:34:54 +0000 https://grupotextiles.com/?p=31527 Good Agricultural Practices (BPA) are more than just a feature; they are a business necessity, thanks to the registration systems that must be implemented as a component of competitiveness. Tomato cultivation in Mexico uses a large amount of agrochemicals. A high percentage of production costs is related to the purchase and application of inputs, including agrochemicals; in addition to increasing production costs, they cause serious disruptions to the environment and the health of consumers and the producers themselves.

BENEFITS OF ADOPTING THE BPA

Improving the hygienic conditions of the product

Preventing and minimizing product rejection in the market due to residues

Toxic or unsuitable characteristics in taste or appearance for the consumer

Minimize the sources of contamination of products to the extent that hygiene standards are implemented during production and harvest collection

It opens up opportunities to export to demanding markets (better opportunities and price). In the near future, it will likely become a requirement to access those markets.

Obtaining new and better information about your own business thanks to the registration systems that must be implemented (certification) and that can be cross-referenced with economic information. In this way, the producer better understands their business, which enables them to make better decisions.

It improves the management (administration and control of personnel, inputs, facilities, etc.) of the line (company) in terms of productivity and economy, and increases the company's competitiveness by reducing costs (reduced losses of inputs, working hours, and idle time).

]]> Protected agriculture in Mexico grows by 43 percent in 6 years. https://www.grupotextiles.com/en/protected-agriculture-in-mexico-grows-by-43-in-6-years/ Fri, 12 Feb 2021 00:30:37 +0000 https://www.grupotextiles.com/?p=30581

Mexico.- The area where protected agriculture is developed, characterized by production using tools such as greenhouses or shade netting, recorded a 43 percent growth from 2010 to 2016, according to data from the Mexican Association of Protected Horticulture A.C. (AMHPAC).

While in 2010 there were 6,328 hectares under the protected agriculture scheme, in 2016 this figure rose to 9,400 hectares, according to figures from the Association, which were made public during the signing of the collaboration agreement for the exchange of data between the Service of Agro-Food and Fisheries Information (SIAP) and AMHPAC.

In volume, the 2016 production exceeded 1.2 million tons of vegetables, highlighted Alfredo Díaz, general director of the Association.

Therefore, Díaz highlighted the importance of having the necessary information about this growing activity.

“(The information) is a significant input to finally be able to plan our businesses properly, in the sense that they respond to whether there is a market, whether there is programming, budget, and finally all the follow-up and evaluation of what we do,” said Díaz.

Meanwhile, Patricia Ornelas, head director of the SIAP, said that it is necessary to strengthen the data and information about protected agriculture, since it is a method that allows increasing food production on less land, as it is easier to control the process.

Of the 236 members of AMHPAC, 81 percent are dedicated to exports, with 77 percent of the total being sent to the United States, as this control makes it possible to achieve the quality required for the international market, according to information from the Association.
