Active substance, dosage form and purpose
The main active component of the herbicide is fluroxypyr, used in an amount of 350 g per 1 liter. The product is intended to control dicotyledonous annual and certain perennial weeds. The preparative form of the herbicide is an emulsion concentrate.
The principle of action of the drug "Demetra"
Within an hour after treating the beds, the weed leaves absorb the active substance. Also, the herbicide is partially absorbed by the roots of vegetation through the soil. The substance actively spreads throughout all parts of the plantings, including growth points, and leads to a stop in the development of plant cells and disruption of the overall growth process.
According to the mechanism of action, the herbicide "Demetra" is similar to indolylacetic acid, which is a natural plant hormone. The substance leads to an imbalance of growth hormones, which causes weed suppression. Violations of cell division and growth occur due to oversaturation of the synthetic hormone.
You can notice the first signs of suppression of unwanted vegetation a few hours after cultivating a plot of land.
Complete death of the weeds occurs after a couple of weeks.
Benefits of use
Treating beds using Demetra has a number of positive aspects. The main advantages include the following:
- The herbicide can be used for a long period of time - right up to the stage of formation of the flag leaf of grain crops.
- No restrictions on crop rotation for further cultivation of plants.
- Highly effective against field bindweed, tenacious bedstraw and other types of weeds.
- Possibility of use in case of re-emergence of weeds.
Consumption rate for different plants
The herbicide consumption depends on the crop growing in the beds and the type of weeds found. The average consumption rate is 200-300 l/ha for ground treatment and 25-50 l/ha for air treatment.
How to prepare a working solution of weed killer
To prepare the working mixture, measure out the required amount of substance to completely fill the sprayer. The drug is infused immediately before the treatment. First, the sprayer tank is half filled with water.
Instructions for use of the finished mixture
After pouring the working solution into the sprayer, the mixture is sprayed onto the ground part of the detected weeds and onto the surface of the beds. Absorbed through the soil into the roots of plants, the substance destroys unwanted vegetation.
Safety rules for use
For safety reasons, when processing beds you need to adhere to a number of rules. Before preparing the working solution and its direct use, it is recommended to wear protective gloves. To avoid inhaling the smell of the drug, you can use a respirator.
The degree of toxicity of the drug
"Demeter" belongs to the third hazard category, which includes low-hazard substances. The minimal toxicity of the drug does not lead to negative consequences, provided that it is used correctly and basic safety requirements are met.
Herbicide compatibility
The drug is compatible with most anti-dicot herbicides, fungicides, insecticides and graminicides. The only limitation is the use of the drug in combination with contact herbicides on onion beds. Before use, you can check the compatibility of the mixture by mixing the drugs.Also, to be on the safe side, it is recommended to check the phytotoxicity towards plants in the beds.
Shelf life and storage conditions
The shelf life is 2 years from the date of release. The production date is indicated on the packaging of the substance. It is not allowed to use the herbicide after the expiration date.
To prevent the drug from losing its characteristics, it must be stored in a dark place, protected from direct exposure to sunlight.
What analogues are there?
As a substitute for the herbicide "Demetra" you can use the drug "Starane Premium". The substances have a similar effect on unwanted vegetation and do not differ in the method of application. Combining these funds is also allowed.
