Perennial and annual grass weeds 

Wherever you and I go, everywhere we will meet weeds or weeds growing on their own. There are many of them in the fields and in the gardens, next to cultivated plants. They get to our sites thanks to the wind, birds, insects and animals.

The presence of weeds in areas with crops leads to a sharp decrease in yield. They draw nutrients and moisture from the ground and are a haven for many harmful insects and diseases. Among them are perennial grass weeds. As a rule, you can fight successfully with the enemy if you know him by sight.

What are weeds

The variety of cereal weeds is great due to the ability of plants to adapt to living conditions. Distinguish:

• annuals (juveniles);
• biennial;
• perennial.

There are also differences in the structure of the seed, some are called monocots, others are dicots.

Dicotyledonous and monocotyledonous

The table shows the main differences.

Among the wide variety of plants that are not cultivated by man, cereals and dicotyledonous weeds occupy.

Especially a lot of weedy dicotyledonous weeds accompany crops of cereal crops. Among them are annual and biennial weeds.

Dicotyledonous Annuals

Most often, our crops suffer from annual dicotyledonous weeds propagated by seeds.

Some of them are listed below:

• mary (swan);
• forget-me-not;
• sow thistle;
• pasture;
• henbane;
• a shepherd’s purse;
• amaranth upturned;
• wood lice;
• various highlanders;
• field mustard (colza);
• blue cornflower;
• wild radish and other weeds.

perennial dicots

The group of perennial dicotyledonous plants is extensive. They grow everywhere. All plants have a strong root system that can withstand drought and severe frosts.

Weeds found in almost all gardens:

• plantain;
• dandelion;
• various types of polynyas;
• thistle field;
• mouse peas (vyazil);
• creeping clover;
• buttercups

cereal weeds

Perennial and annual grass weeds are malicious pests of cultivated plants. In nature, there are more than 6 thousand of them.

But appearing in gardens, fields and gardens, plants become malicious weeds that need to be fought.

These herbaceous plants have a hollow culm-stalk with internodes. The leaves are narrow, the placement is parallel. The inflorescence produces inconspicuous flowers. Inflorescences are in the form of an ear, panicles sometimes brushes. The fruit is a dry grain.

All plants have a well-developed root system. It is fibrous or branched, but mostly located closer to the surface of the earth. Just imagine what a branched root of cereal weeds, for example, creeping wheatgrass. Here they are in the photo.

Here are examples of some cereal weeds photos and names:

1. Creeping wheatgrass. The people call him a reaper, a rye, a dandur. Settling in the garden, he can displace other plants. With its fibrous system, it draws juices from the earth, depleting it. The roots grow up to 12 meters. This grassy weed grows especially well on loose, fertile soils.
2. Chicken millet grows everywhere. The plant is tall, up to 20 cm, sprawling. One bush occupies a large area. The wide leaves of this grassy weed require a lot of nutrients and moisture, which it takes from cultivated plants.
3. Rosichka blood-red feels great even on acidic soils. In spikelets-panicles, a huge number of small seeds ripen, germinating already at 2 degrees Celsius.
4. Bonfire rye grows in Siberia, in the Far East. The plant is winter-hardy and drought-resistant. The seeds ripen in the spikelet. If they go to a depth of 10 cm, they will not be able to germinate. The height of this cereal perennial weed is comparable to the height of wheat by the end of summer, so the seeds of the bonfire can be in the harvester bunker during harvesting. The particular harm of this plant is in reducing the quality of food grains.

The list can be continued for a long time. Let’s name a few of the most common cereal weeds in our gardens:

• broom ordinary;
• common reed;
• humai or wild sorghum;
• pike soddy;
• wild oats;
• bluegrass.

How to deal with weeds

No matter what weeds, annuals and perennials have appeared in your garden, you need to get rid of them immediately.

There are various ways to deal with green pests of gardens and orchards:

• mechanical or agrotechnical;
• folk ways;
• application of herbicides.

Agricultural technology against weeds

Firstly, a good gardener never has a single piece of land empty. He will always find a crop that can be planted even on a small patch. Therefore, there is no room for weeds to grow and develop. This is one of the agricultural practices.

Secondly, regular weeding and loosening do not allow weeds to rear their heads.

Thirdly, mulching of beds, paths on the site is widely used to deprive annual or perennial weeds of light. In this case, already sprouting plants die, and the seeds cannot germinate. As mulch, you can use improvised materials:

• old newspapers;
• cardboard;
• sawdust;
• tree bark;
• pieces of roofing material;
• old boards;
• dark film.

As a rule, agricultural technology for growing cultivated plants helps to get rid of weeds in summer cottages and household plots. But if there is no desired result, you can use the products of chemical production.

Tough control measures

If it is not possible to get rid of monocotyledonous and dicotyledonous weeds by traditional methods, experienced gardeners recommend the use of herbicides. The choice of drugs today is large. You can use:

• Roundup;
• Hurricane;
• Tornado;
• Lapis lazuli.

The remedy through the leaves goes to the root. Weeds after spraying turn yellow and die. Preparations do not accumulate in the soil. But it is advisable not to plant cultivated plants in the current year on the treated area, so that it is possible to eradicate weeds to the end.

How to deal with weeds:

To summarize

Flowering plants are good to admire in the forest or in the meadow. But when annual or perennial dicotyledonous or monocotyledonous weeds and grasses appear on a plot with vegetables, there is no time for beauty. Delay in their removal can adversely affect the yield.
