Dicotyledonous weeds: varieties and features

Ducotyledonous weed - the scourge of field growers, gardeners and gardeners. It is not planted, but it grows. They fight him with all available means, but he survives. I wish cultivated plants had such a will to live!

If you ask scientists, dicot weeds are wild plants that live on agricultural land. If you ask summer residents and gardeners, then … Probably, it's better not to repeat what they say.

Why are these weeds called dicots? The name speaks for itself - their embryo has not one, but two cotyledons.

Like other plants, weeds come in annuals and perennials.

Fight - man against weeds

Efficiency is important in the fight against annual dicotyledonous weeds. If you do not let them seed, you can completely rid your site of uninvited guests in 2-3 years.

This method will not work with long-term representatives of their class.

Tricks and ways to fight

Let's list the ways to deal with dicotyledonous weeds:

  • Mechanical. Depending on the size of the plot, a hoe, a flat cutter, a cultivator, a walk-behind tractor are used.
  • Chemical. System and contactherbicides.
  • Biological. The use of biogenic preparations, phytopathogenic microorganisms and viruses. Use of birds.

You can use these methods of fighting separately or use them one by one.

In small areas, mulching the soil with a dense, opaque material brings good results. Almost all types of weeds can be eradicated in 1-2 years, although some weeds take longer.

The dicotyledonous weed is not only an uninvited freeloader. Among them are many medicinal plants. Many weeds love to be eaten by pets.
