Weed control is very troublesome and difficult. They are less demanding in terms of growth than vegetables and fruit because weeds appear first, far outstrip the growth of vegetables, and then completely crowd them. Weeds are extremely tenacious and give a lot of seeds that are easily dispersed by the wind, rain water, agricultural equipment and animals over long distances.
Chemicals that are used to control weeds are called herbicides (from the Latin word "herba" - "grass", "caedo" - "kill"). Herbicides are derivatives of different chemical compounds. The bases of their application are morphobiological, anatomical and biochemical characteristics of plants. Compositionally, herbicides can be divided into organic and inorganic. Depending on the effects on plants herbicides can be divided into two groups of a continuous and selective action.
Herbicides of continuous action (nonselective) can affect any vegetation to which they are applied, penetrating the plant through the leaves. They are used in areas free of cultivated plants (after harvesting, etc.), as well as for destruction of weeds along roads, forest belt and on the edges of fields.
Recent achievements allow applying some herbicides of continuous action in the same manner as the elective ones. This technique has become feasible thanks to the cultivation of genetically modified crops, particularly sugar beet and potatoes. Such cultures are endowed with a gene that is resistant to herbicides.
Herbicides of selective action (selective) are used to destroy unwanted weeds. They do not harm the crop competing with weeds for nutrients, light and moisture. Selective herbicides contain substances of different chemical classes with different mechanisms of action. Often antidote is used in the production, it’s drug that excludes herbicide phytotoxicity in relation to the crop. We would like to highlight certain types of well-proven herbicides.
When choosing an herbicide for crop production you should be guided by the following rules:
1. Use the data of the "Handbook of pesticides and agrochemicals permitted for usage in Russian Federation"
2. Take into account the zonal features to determine the amount and rate of the preparation of working solution, the timing of its application and development phases of individual cultures. In the application of soil herbicides you need to know the extent of soil heart and humus content in it, soil type and texture, the rules of application in the soil.
Company «Dacha Group» is interested in expanding the line of "Sornyaka.net." We are willing to consider offers of cooperation from the manufacturers of modern tools for weed control.
