Effects of climate change on agriculture: trellising net as a preventive method against crop damage.

Heavy rains due to climate change, increase crop failures due to humidity related pathogens.

Today is essential to cultivate using trellising net when growing vegetables due to climate change. We are facing possibly irreversible climatic changes that have modified in short term our climate worldwide, changing ecosystems, breaking balance of the environment for the species that live in the planet, modifying the food chain by having catastrophes, floods, hurricanes, desertification, polar thaw among other effects to be mentioned.

climate change and strong wind

Strong winds are a consequence of climate change, affecting crops that lack a good support system.

climate change

Landslides affect nearby crops causing economic losses of great importance.

climate change and diseases

The trellis net prevents the fruits of cucumber are in contact with moist soil thus prevent the spread of diseases by fungi or bacteria growing in soil moisture.


There are different subjects we may mention referring this matter, but there is one particular that concerns all of us and it is the effects of climate change on our crops. We know we are facing huge production losses of food (especially vegetables, grains, horticulture) and we now need to import or “borrow” production between states, countries and continents, to fulfill the great demand that current overpopulation requires.

A clear example can be seen the highly adaptive vegetable the cucumber or its scientific name cucumis sativus L.  that is used for food and industry, being a tropical species,  demands high temperature and relative humidity also must also be high. However cucumber adapts to warm and hot weathers and is cultivated on coastal areas up to 1200 mt above sea level. Over 40 degrees centigrade plant growth stops, and also below 14 degrees c development halts as well, in case this too high or too low temperature is prolonged,  female flowers will fall and no fruits will be achieved.   Furthermore, the cucumber plant dies when temperature go below 1 one degree centigrade,  it starts to wither and it will be very difficult to recovery from.

trellis net and climate change

Cucumber plants grow in a better way when they are tutoring with trellis net.

Regarding relative humidity of the air, this crop is very demanding, with the exception of the harvesting and picking stage, period during which the plant is susceptible to fungal diseases, that prosper in high relative humidity: preferably rainfall and humidity must be low so diseases incidence is reduced. Fruit quality in humid zones is lower than in dry zones. Cucumbers are very demanding, the general advice is to place the crop in sunny areas as high sun exposure stimulates flower fecundation, while low light intensity reduces it.

Another factor to consider is mechanical stress or outright damage and losses due to the wind.  Several hours of wind duration with gusts higher than 30 km/hr, accelerate the plant´s water loss, while lowering relative humidity, increasing hydric demand, reduce fecundation because of less humidity on flowering stiles.  Wind will definitely cause growth to stop due to mechanical stress, it reduces production and accelerates plant´senescence, by damaging foliage, specially stems and leaves.  This whole scenario will add to the looses in production and economic investment affecting agricultural sector.

Diseases caused by rupture tutoring system can be prevented using trellis net.

climate change and HOTOMALLAS

Tutoring your crop with trellis net provides better support to crops,resisting  way better moderate winds.

Climate change is the reason why if we decide to establish a crop and good production yields of quality produce, we must decide to adopt plant tutoring with HORTOMALLAS trellising net  to enhance quality on vegetable cucurbit variety, this tutoring gives support to vegetables and protects it from heavy winds avoiding nutrient loss like water, improving phyto-sanitary conditions from its development until harvesting because its easier to manipulate while picking the product, increases  flower fecundation while increasing sun exposure and decreases plant humidity by controlling it causing better growing , production and foliage, and systemic conditions like brix degrees, strengthening 100% its development.

Hortomallas Hortomallas

HORTOMALLAS manufactures and markets crop support nettings (trellising and tutoring as alternatives to the raffia twine labor intensive traditional system) that increase crop quality. Our Mission is to: INCREASE VEGETABLE CROP YIELD AND PROFITABILITY TO ALL THOSE VEGETABLES THAT NEED TUTORING AND SUPPORT USING NETTING INSTEAD OF RAFFIA. Since 1994 we help professional growers and farmers improve their cucumber, tomatoes, melon, zucchini, bean, chile, peppers crops where trellises and supports are needed. HORTOMALLAS is the ideal system for cucurbitacea and solonacea to improve their phytosanitary conditions, while increasing the solar exposure and the brix degrees. Besides the obvious labor costs savings, the use of HORTOMALLAS increases the life span of the plant, allowing longer periods of harvests and of a greater quality. Call us, our crop specialists will help you with specialized attention in the Americas and the Iberian Peninsula!
