The use of raffia twine for agriculture could bring you great losses

Raffia isn’t longer a very efficient tool for plants.

Raffia twine was an amply used material by agronomists, but has fallen into disuse in recent decades, and here we will explain you why.

Raffia twine for agriculture started to be used because of being relatively cheap, strong and light, but after many years it was verified how unfavorable it was; here are some of the most important reasons:

Raffia is the perfect hiding place for fungal fungi.
  • Since it is an organic material, it is very easy for fungus, plagues and bacteria to lodge between the string’s threads. When this happens there is no possible way to go back, because these microorganisms become immune to fungicides and repellents by hiding very well into the grooves of the twine. Obviously, this makes raffia twine for agriculture a source of infections that can easily contaminate the whole harvest by spreading themselves through the trellis. Another fact about this is that the presence of pathogens will weaken the string, causing its breaking off and the whole net’s as well.
  • It makes agronomists use more material than what would normally be used with newer and more efficient methods. Raffia twine for agriculture nettings has to be rearranged as plants grow, and this makes you use even more material to attach and tutor new branches.
  • When a net is broken (and this happens very often) you cannot simply repair that portion, it is necessary to replace the whole netting.
  • Because of having to rearrange the trellis several times, plants and crops take the risk of getting infected by mechanical stress due to constant manipulation; therefore, a considerable fraction of the harvest is always lost.
  • It takes a long time and a considerable labor inversion to make raffia string trellises, making farmers losing more money and time.
  • If they lasted a whole season, raffia nettings still could not be used again. This is so because they would not last long, so making new ones turns out to be cheaper.

It seems strange how, in spite of having all these prejudices, raffia twine for agriculture has been used for so many years. In the wake of these problems, a lot of synthetic versions of raffia were released to the market. Nevertheless, although they have an awesome quality and do not share traditional raffia’s disadvantages, it might be impractical and expensive.

There are other methods that can replace raffia, obtaining better support results.

However, there is a great replacement for raffia twine for agriculture which helps agronomists to save time and money, and it is plastic meshes. They come ready to be installed so it is not necessary to make a trellis, saving time and labor. Also, it is not needed to be readjusted as plants grow, so you can save material and crops end up less harmed due to constant manipulation. Besides raffia trellises, plastic ones do not contract infections because since they are inorganic it is impossible for plagues to lodge the material; because of that they can be washed and reused up to 4 times, depending on the conditions of the planting, which makes it an excellent alternative to low costs and improve the quality and sanitary measures of plantings.
