Galium the winter grain weed

Galium spp, also known as Gardener’s Love, Limpet or Rasperuela, is one of the most common weeds in winter cereals. Controlling Galium is crucial for good harvest yields and optimal grain and fruit quality. In this post, we are going to see what it is and how it behaves and what techniques we can apply to control gallium and other winter weeds.

What is Galium?

Galium (Galium aparine L or Galium tricornutum), is one of the weeds known to most winter cereal farmers or horticultural plantations. Galium is an annual herbaceous plant, of the Rubiaceae family that comprises more than 400 species.

Galium is a creeping and climbing plant that can reach one and a half meters in length. Its leaves are seated and whorled covered with hairiness at the ends, it makes a small white flower that is born in groups of 2 to 5 flowers in the axils of the leaves. Galium is a very common weed species in extensive crops of winter cereals, beets, artichokes and other vegetables.

How does Galium develop in crops?

Its distribution is general throughout the peninsula and can be seen in any type of soil. However, Galium can be seen very commonly in heavy, clayey soils, where moisture and nutrients are highly retained.

Galium is one of the weeds that has the ability to germinate in a staggered manner. This is so because the birth begins well into the fall, at the end of October and the beginning of November, and lasts until the end of February. This staggered germination of Galium makes it a difficult weed for herbicidal treatments.

Galium plants have a very powerful root system that makes them very resistant to environmental conditions. In addition, each Galium plant can produce around 400-500 seeds per plant. These two characteristics make Galium a very resistant and powerful weed when it comes to fighting it. However, Galium seeds have a dormant period in low soil, so if they do not germinate in a short time (1-2 years) they do not survive.

What are the techniques to combat Galium on our farm?

We have seen that Galium family weeds are a major problem for field crops if we do not solve it in time. To combat and control Galium on our farms, it is advisable to follow different techniques that allow us to cultivate without ending up having our fields full of Galium.

In agriculture the key to success is to diversify control measurement techniques to ensure maximum control of Galium and other weeds.

Crop rotation

Crop rotation breaks the monoculture and the same conditions and practices periodically, which greatly facilitates the control of weeds that are very well adapted to an indefinite monoculture. In addition, it allows us to have our plots without cultivation at different times, which means that we can control Galium and weeds in general by mechanical or chemical means.

False seeding

The false sowing consists of preparing the soil for the sowing of the crop that we want to implant but waiting a few days before sowing to allow the weeds to germinate. This technique has a low efficiency with Galium since, as we have commented previously, they germinate in a staggered way. However, it can be a technique that controls part of the birth. As we have said, we should not focus on one technique but on seeing that they are all complementary.
