Galium spp, also known as Manger’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 grows 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 on 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 the Galium family weeds are a major problem for field crops if we do not solve it in time. To combat and control Galium in 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.
Weeds in winter cereals
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.
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 the 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.
With the tillage, we turn the earth and bury the Galium seeds at 25-30 cm, so they will not be able to germinate. If we take into account that they do not have a very long dormancy (2 years), we can till every certain period of time to bury good seeds and dig up seeds that are no longer going to germinate.
Certified and clean seeds
This measure is basic to avoid sowing weeds such as Galium when we fill our planter. If we choose to buy certified or very clean seeds, we will save Galium, weeds and herbicide treatments.
Precise mechanical weeding
In extensive crops such as cereals, there are precise tines (GPS) that weed the soil superficially between rows of the crop. This means that we can start the Galium at the moment of germination without the use of herbicides.
Especially in the seeders, tillage machinery and harvesters, Galium seeds and weeds accumulate that we move from one field to another. The cleaning of the machinery is essential for its duration and care but also to avoid unintentionally sowing weeds.
Herbicidal treatments are essential to control weeds such as Galium. However, and due to the staggered germination capacity that Galium has, it is important not to focus purely on making herbicidal applications and to vary the active materials used to avoid resistance.
