Protection of organic crops, Arrigoni screens pass the tests on “Baby Leaf”

Protection of organic crops, Arrigoni screens pass the tests on "Baby Leaf"

SCIROCCO MD WHITE and BIOMAGLIA in the tests show effective protection and unchanged quality compared to the open field

Arrigoni, the group specializing in the production protective screens for agriculture, is confirmed as an excellent ally for organic farming.

The excellent results obtained following a test in the field for the control of flea beetles bear this out. The test was performed on an organic rocket seeding, started in early September and harvested 17 days later. Both SCIROCCO MD WHITE (windbreak and medium shading net, in flat weave HDPE monofilament) and BIOMAGLIA (light polyamide net, anti-insects and anti-frost) were tested, positioned on the crop immediately after sowing and kept until the harvest.

The test involved an area of over 5,000 square meters, sown with the rocket variety Extrema, from the Maraldi Sementi company in Cesena.

The test response was positive: the protected rocket had the same quality as the not covered rocket. It showed neither signs of suffering, nor differences in quality (such as color or consistency), even the yield was the same.

A further confirmation of the results of BIOMAGLIA then comes from another field test conducted at the Azienda Agricola Fratelli Cambise in Trasacco, L’Aquila, historical reality that for over thirty years has specialized in the production of leafy vegetables. The technical manager Sandro Cerasani explained: “For this type of crop, the main problem is naturally represented by virus diseases, whose main vector is the thrip. To counteract their spread, we did a test with Arrigoni Biomaglia on lettuce, broccoli and radicchio. The outcome was extremely satisfying, with the percentage of infected plants close to zero, so that given the results we are already thinking of enlarging our surfaces protected by Biomaglia from Arrigoni”.

“The most important aspect – highlights Milena Poledica, an agronomist from Arrigoni – is that surfaces protected by Arrigoni screens did not require phytosanitary treatments against the flea beetle or the thrip, neither show any damage to the crop. It is clear from the test that the use of physical protection through Arrigoni nettings on the crop is extremely advantageous, both in terms of cost and in terms of effectiveness. And above all, it offers the possibility of collecting a product free from pesticide residues and, therefore, healthier. An essential choice for those working in the organic sector “.

According to the latest ISMEA report, released on Sana 2019 (the international exhibition of organic and natural products), the positive trend of the last fifteen years continues for the organic sector. Having now emerged from the niche dimension of the origins, in recent years it has become a widely spread lifestyle consolidated in the eating habits of Italian families. Over the past decade, organic production and processing companies have doubled overall, while organic farmland has grown by 60%. At the end of 2018 the area cultivated in Italy with organic agriculture reached almost 2 million hectares, with a number of farmers reaching 80,000 units. The elaborations carried out by Sinab (Sistema di informazione nazionale sull’agricoltura biologica – National Information System on Organic Farming) indicate that since 2010 the increases recorded are over 800 thousand hectares and 20,000 are the farms engaged in this sector. Compared to 2017, the biological surfaces increased by 3% with 49,000 hectares more.

It is now a fact that the problem of reducing pesticide treatments in order to offer a product with less residues is increasingly felt, even among companies specialized in the production of vegetables and of salads. Furthermore, the use of many molecules is proving to be ineffective, therefore the application of pesticides is a counterproductive choice by many parties. In this sense, the choice of physical barriers represents a solution that is as valid and concrete as it is “green”.

From Arrigoni the “shield solutions” against hail

Protection of organic crops, Arrigoni screens pass the tests on "Baby Leaf"

In fruit-growing, from apple to kiwi, passing through the vineyards, protection is assured and can also be integrated against the Brown Marmorated Stink Bug.

June 12, 2019 – Como – Hail is one of the most adverse weather conditions for fruit growers, due to its often-devastating effects. It can destroy entire crops and put the plants in the condition of not producing even in the years following the event. In recent seasons, thunderstorms with hail have become a constant of all summers.

Arrigoni, a leading international player in the technical textile sector for agriculture, now offers solutions that are not only effective, but environmentally sustainable, calibrated on individual crops and particularly versatile for every need too.

FRUCTUS® is the special line of nets woven with UV-stabilized and high-tenacity HDPE monofilament. These nets are made with Leno weave, that is, made up of two different monofilaments for each warp chain. This particular weave ensures the run-proof characteristics of the net, together with remarkable tenacity and long duration. Equipped with strong lateral and central selvedges, the nets of this range are particularly suitable for the installation in long rows. Finally, the FRUCTUS range nettings are particularly versatile and fulfill the different needs of each anti-hail system.

IRIDE® instead, it is available in the UVA and DUE versions and is an effective range of anti-frost and anti-hail screens, highly run-proof thanks to their knitted mesh monofilament. The range offers nets ideal for covering tunnels, greenhouses and orchards. In addition, IRIDE MULTI PRO ensures the right hole size, thick meshing and robustness, the features that make this net the ideal solution to exclude the harmful Brown Marmorated Stink Bug, even in combination with FRUCTUS range nettings.

The anti-hail systems for the protection of orchards can also be grouped into two types, depending on the plant pattern, the morphology of the land and other important variables. These are the Flat system and the Roof-style system. In the Flat system, the nets are installed horizontally to allow for easy passage of machinery. The relative ease of installation makes it the cheapest system, also for the relative ease of installation. The Roof-style system was the first anti-hail system used to protect plants. The nets are installed at an angle to help the hailstones slide off, avoiding dangerous accumulations that could compromise the stability of the structure.

Arrigoni, to these two basic solutions, also adds the possibility of configuring a special V5 System, which represents an evolution with respect to the Flat system. The V5 was in fact recently developed to solve the problem of hail discharge from the nets. Poles, anchors and nets remain the same as the Flat system, as well as the height of the structure, determined by the longitudinal cables. What changes is the tension strength, reached with an elastic cable between the nets, which thus form a “V” between the rows. In this way, the hail is collected and channeled, which helps its discharge from the nets. The V5 system can also be installed on all types of orchards, with a distance between the rows greater than 3.5 meters and a height of 5 meters.

“Climate change – commented Paolo Arrigoni, CEO of Arrigoni – is strongly affecting agriculture in various countries around the world. Even the intensity and frequency of phenomena such as hailstorms is been affected consequently. In Arrigoni we have long been committed to studying effective solutions to limit and face these new challenges, always respecting eco-sustainability, a principle that guides our philosophy. FRUCTUS® and IRIDE® represent concrete proposals that are easy to apply and are distinguished by their practicality and effectiveness on the most diverse crops, from apple trees, to kiwis, to vineyards, to fruit crops in general”.

Tomato and pepper, 7 proposals from Arrigoni to increase productivity

Protection of organic crops, Arrigoni screens pass the tests on "Baby Leaf"

Depending on the needs, the company presents innovative solutions ranging from anti-insect screens to mulching fabrics and nettings to retain pollinators.

Tomato and sweet pepper are among the most important vegetable crops in the world, with production amounts constantly growing. Specifically, according to FAO data, in 2017, 182.301 million tons of tomatoes were grown all over the world, reaching a new record. In fact, production has increased by 35.76% in the last 10 years. On a global level, according to FAO data, the production of peppers is also positive and, to date, the cultivated area is close to 530,000 hectares, for a production of about 550,000 tons. Whether open field cultivations or in greenhouses, producers around the world are constantly looking for ways to reduce the environmental impact of production, seeking for meeting the growing needs of the market and consumers.

Arrigoni, leading international player in the technical textile sector for agriculture, provides producers of tomatoes and peppers with 7 different solutions with aim to respond on all problems in production of these crops.

Biorete Air Plus® is a range of safe and eco-friendly anti-insect screens against insects, able to reduce pest access to plants and transmission of viral diseases. Available in differently hole size, they provide maximum protection against even smallest insects, such as aphids and thrips (Thripidae). Furthermore, the innovative ARLENE HT® monofilament with low thickness and high tenacity ensures high resistance and greater ventilation.

Prisma® is a range of white shading screens with special Light Diffusion additive that improves light conditions in protected aria, prevent sun burns and stimulate photosynthesis. Field tests confirmed that light spreads more uniformly around the plants, even in the lower parts of the canopy. White color to keep temperature down due to reflection part of sun light. Lower temperatures positively affect plant development, fruit firmness and content of polyphenolic compounds.  More pleasant temperatures and working conditions were confirmed even by operators.

Agritela® is then a polypropylene mulching fabric, stabilized against ultraviolet rays, breathable with high mechanical resistance (it also withstands the passage of small tractors). Actually, it is the answer for those who, having cultivated many times in the same land or environment and for different seasons, find problems of “tired soil”. Agritela® guarantees soil transpiration, weed control and easy cleaning of production surfaces for pots or bags with substrates.

Arricover® is a strong, transparent and breathable fabric that combines high quality, light weight, long life and effective protection against adverse environmental conditions. It allows applications on supports and is easy to lift and reposition when necessary (for summer storms, hail, dew and pollination). The agronomic results obtained on the peppers and tomato crops are very interesting: better plant growth after transplanting, protection against rain and hail, quick drying thanks to the typical transpiration of knitted fabrics and less fungal diseases.

Impollirete® retains pollinating insects inside the greenhouse. The process of pollination of tomatoes and peppers, in fact, usually takes place using insects such as bumblebees. To optimize their activity, Impollirete® keeps pollinators inside, simply closing the roof and the side openings of the greenhouses.

Iride Base® is a light mesh, made from high density polyethylene knitted monofilament, suitable for open field installations on supports and for installation on tunnels. It protects peppers and tomatoes from hail. In addition, it can protection against strong insolation thanks to the slight shading factor of 12%, support better plant growth, less damage from insects, stronger and healthier plants.

Rete Garofani & Solania® is a large mesh extruded net for plant support. Thanks to its robustness, applied on arches, it supports pepper plants and their fruits. In addition, the net improves plant development and distribution, prevents damages to the buds, facilitates harvesting operations and keeps plants stable in strong winds.

“Solanaceae – says Milena Poledica, agronomist and researcher of Arrigoni – belong to a family of plants highly sensitive to numerous diseases, parasites and pathogens transmitted by insects. Moreover, they are one of the most cultivated crops in the world too. A Company like ours, which is a global partner for agriculture professionals, has developed a range of solutions suitable for any type of environment and climate, to offer protection and guarantees to those who produce in a responsible and sustainable way, looking to the future”

Through PROTECTA® and PROTECTA® SYSTEM the future of healthy fruits without pesticides

Protection of organic crops, Arrigoni screens pass the tests on "Baby Leaf"

Cherry cultivation is one of the most complex and delicate crops. Like other fruits such as kiwi, peach or plum, it can suffer important negative effects from excessive rainfall, increasingly common in the season of fruit ripening (starting from the second decade of May).

Leading international player in the technical textile sector for agriculture, Arrigoni proposes new solutions that improve cultivation practices. Moreover, it combines the possibility of protecting crops from the attack of harmful insects, such as the dreaded Drosophila Suzukii and other species to the advantages of defense against atmospheric agents.

“Until now – explains Giuseppe Netti, agronomist from Arrigoni – damages of rain on cherries was prevented by means of plastic film covers. In several cases this solution produces satisfactory results. However, it is not 100% effective. This is due to the fact that a totally “waterproof” product reduces the air passage (which remains only in the horizontal direction) and favors a moist environment on sunny days, altering the microclimate of the orchard and causing an excess of humidity. Consequences are damage or reduction of the harvest. Moreover, such a cover can cause serious damage to the structure in the event of strong winds”.

“Arrigoni research has thus developed a specific innovative product: PROTECTA®. This is a new concept of coverage – Netti continues – which guarantees multiple advantages: reduction in the percentage of water flow; maintaining sufficient air flow and a good microclimate; high mechanical strength; long life (over 6 years in Italy); hail, wind, frost and sun protection”.

PROTECTA® by Arrigoni is made of high tenacity ARLENE HT® monofilament and contains special additives to increase its durability and favor the sliding of rain outside rows. The resulting mesh fabric is very dense (39 threads per square centimeter), which allows to break up the drop and reduce the passage of water by about 90%.

“The tests on PROTECTA® – Netti specifies – were carried out by subjecting the fabric to a very high rainfall intensity: 60 mm/h, or the same conditions as a heavy downpour”.

To combine the advantages of a safe rain protection with those of excluding the most invasive insect species from orchards, Arrigoni has also developed PROTECTA® SYSTEM. In this case, the rainproof fabric is complemented by the side protection provided by BIORETE® screens, which are effective in preventing harmful insects from reaching the crops and causing damage in fruit-growing. The insect protection system consequently reduces the need for pesticides, with solutions that manage to counter the attacks of Drosophila Suzukii and other harmful insects.

“To these highly technological proposals – concludes Netti – we combined great ease of installation and collection operations. For example, with PROTECTA® SYSTEM installed row by row, BIORETE® screens must simply be rolled up, otherwise the plants are always sheltered and protected”.

Invasive insects and climate changes, Arrigoni answers with “green healthcare”

Invasive insects and climate changes, Arrigoni answers with “green healthcare”

At Fruit Logistica the Italian Company presented innovative proposals with zero environmental impact.

Arrigoni, a leading company in the design and production of protective screens and nettings for crops, focused its presence at this trade show on the agriculture of the future. A 100% sustainable and completely zero environmental impact way of producing, both for humans and for the environment.

The importance of the event was highlighted not only by the company stand set up during the trade show in Berlin, but also by the organization of a conference, held on February 7th in the “Tech Stage” space of the fair: “Invasive insects, climate change and new phytopathological threats: advanced agrotextiles for safe food and climate control”. For the occasion, CEO Paolo Arrigoni and Milena Poledica, PhD agronomist and researcher of the Group have been present.

“The production of fruit and vegetables – explained Poledica – today is increasingly limited by pests, often pathogens vehicles. Damage caused by these vectors and plant viruses is economically significant and, if not contained in time, can also lead to total loss of the crop. According to a recent study conducted by the University of Paris-Sud / Cnrs / AgroParisTech and published in the journal Nature Communications, the minimum annual cost of damage caused by invasive insects in the world amounts to 69 billion euros.

On the other hand – continued Poledica – the control of pests usually involves an intensive use of pesticides, but this in turn affects both the environment and human health. Climate change, however, will contribute to global migration or the expansion of many species of insects. Hence the need to find innovative solutions that meet the needs of modern agriculture and protect the environment and human beings”.

In this context are included the high-tech applications of Arrigoni as Biorete Air Plus®, a full range of high-tenacity, dense and lightweight insect screen nettings, composed of polyethylene monofilament meshes. The white-transparent color ensures maximum brightness to the crops, while the different meshes of the nets allow the defense targeted by the different types of insect.

“Another problem of modern agriculture, and indeed one of the most difficult global challenges – also recalled Poledica – is represented by climate change.  According to the FAO 2018 report on the state of global agricultural markets (“The State of Agricultural commodities markets 2018”), climate change will increasingly disrupt agricultural systems and the food market in the coming years. Countries that are in the temperate climate zone will have benefits for agriculture due to the rise in temperature, but countries that are in low latitudes will see a deterioration in the performance of their agricultural systems. From this point of view, it is evident that agriculture needs to be increasingly supported by research and technology, to identify effective solutions that, at least, can help to stem the expected changes in the climate. This is why we developed solutions both to improve the diffused light inside greenhouses and to control the reflection of sunlight, and to guarantee adequate protection in case of rainy events “.

Arrigoni proposals that increase diffused light and, at the same time, control the sun-rays, are the Robuxta® and Prisma® range, whose advantages can be summarized in the following key concepts: high mechanical strength, long lasting, light management and temperature reduction; better plant development, higher yielding and crop quality. Thanks to white color and light diffusion additive plants receive diffused light, more photosynthetic active radiation and grow in more comfortable environment; fresher environment and healthier plants, thanks to the choice of white color; less damage due to direct radiation thanks to the diffusion and reflection of infrared rays.

Protecta® instead offers protection from rain with greater ventilation. Combined with BIORETE® AIR PLUS it becomes a system that, in addition to reduce the passage of water up to 90%, acts as an effective shield against insects.

“Modern agriculture – commented Paolo Arrigoni, CEO of the Group – requires new approach taking into account the changes under way at global level. Our Company started precisely from this consideration to advance innovative and effective proposals. Our commitment, now, is to continue working on the theme of “zero impact” and high added value solutions, according to our green healthcare philosophy”.
