Protection for leek and onion

Recommended solutions


All onion family members are sensitive to low temperatures and frost can make significant damages to young stalks and bulbs Weather stresses like spring frost, low humidity, insufficient heat, hail etc. impact development of foliage and directly influence bulb production. Therefore, the onions production require higher temperatures and low humidity for optimal development of foliage and later bulb in classical onion production.


ARRIGONI ha sviluppato l’innovativo ARRICOVER: un tessuto forte, trasparente e traspirante, che unisce alta qualità, leggerezza, lunga durata e protezione efficace da condizioni ambientali awerse. Facile installazione: ARRICOVER può essere posizionato

For this aim ARRIGONI developed the innovative ARRICOVER- strong, transparent and breathable fabric witch combines high quality, light weight, long duration and effective protection from adverse environmental conditions. Easy installation-ARRICOVER can be placed

directly on crops and it can stay until harvest or when weather conditions become more favorable. Installation to the ground can be done with methods usually used for other protection systems (with sticks, stones or piles of earth).



Frost protection
ARRICOVER transparency combined with the typical transpiration of knitted fabrics provides good gas exchange and create dried habitat.
Less humidity in natural habitat increases frost resistance of plants. As physical barrier in process of freezing ARRICOVER keeps water deposited on surface of fabric instead of crops surface. Furthermore, this freezing process on surface of ARRICOVER fabric improves exothermic reaction and creates heat which additionally increases temperature of plant habitat.


ARRICOVER provides minor fluctuations in relative humidity and reduces the stress caused by dehydration. Weaken thermal shocks by reducing temperature oscillations.
The particular transparency of ARRICOVER allows the passage of light and creates optimal conditions for photosynthesis. Good permeability of fabric creates environmental without condensation and less favorable conditions for fungal diseases development. Thanks to the favorable microclimate under the net, leek and onion plants protected by ARRICOVER have optimized ratio between vigor and generative potential, better vegetable visual appearance and nutritional quality.


As physical barrier ARRICOVER protects plants from heavy rain and light hail. It prevents contact with different insects, animals and birds that could cause relevant damages in plantations. Furthermore ARRICOVER protects crops from the wind action and mechanical damages. At same time the strength of the fabric allows use in windy areas without risk of tearing. In extreme weather conditions it is possible to place ARRICOVER onto non woven fabric AGRIVELO in order to obtain a higher protection and increase temperatures during sunny days.
