The herbicide "Demetra" is a systemic agent that helps control annual and perennial weeds. It effectively kills birch and bedstraw. To achieve the desired results, it is important to strictly follow the instructions. Adherence to safety precautions is also crucial. If the substance enters the body, seek medical attention promptly.
Composition, release form and purpose
The active ingredient of this product is fluroxypyr. One liter of the product contains 350 grams of the active ingredient. This herbicide belongs to the chemical class of triazines. It is produced as an emulsifiable concentrate and packaged in 5-liter plastic canisters.
Mechanism of operation
The active ingredient easily migrates through the phloem and xylem. It spreads well throughout the plant, including the growing points. However, the substance disrupts cell development in crops and affects growth processes.
As a result, oversaturation with the artificial hormone occurs. This provokes disruption of cell division and development.
Advantages of the drug
The key advantages of the product include the following:
- if the conditions of application are met, the first symptoms of weed suppression appear several hours after the use of the herbicide;
- complete destruction of weeds occurs within 2-3 weeks;
- helps to cope with particularly malicious weeds - these include bindweed and bedstraw;
- in tank mixtures it is combined with herbicides based on 2,4-D, 2M-4X;
- is characterized by high systemic activity – the composition quickly penetrates the structure of weeds and blocks their growth;
- characterized by high selectivity for the plant at all stages of development;
- there are no restrictions for the following crops in crop rotation;
- helps protect crops from the moment of treatment until new weeds appear.
Calculation of consumption for plants
To ensure the desired results, it's important to strictly adhere to the dosage. It's listed in the table:
| Consumption rate of the substance | Culture | Weeds | Processing Features | Waiting period (number of treatments) |
| 0.43-0.57 | Spring and winter wheat, spring and winter barley | Annual and perennial weeds, including field bindweed, bindweed, and tenacious bedstraw | Plantings should be sprayed at the tillering stage and during the initial stages of weed growth. Winter varieties should be treated in the spring. The application rate of the working solution is 200-300 liters per hectare. | 35 (1) |
| 0.57 | Spring and winter wheat, barley | Spray the plants at the end of stem elongation. 200-300 liters of working solution are required per hectare. | ||
| 0.4-0.5 | Onions, with the exception of varieties grown for their greens | Apply the solution when the plant has just one or two leaves. Apply 200-300 liters of the working solution per hectare. | 60 (1) |
Preparation of the working mixture
The working fluid must be prepared immediately before application. To do this, measure out the required volume of the solution for one fill of the device. It is recommended to add the product directly to the sprayer tank. The hydraulic agitator must be running during this process.
The sprayer tank should be at least half filled with water. Rinse the pesticide container several times with water and pour its contents into the tank.
Instructions for use
The product is recommended for application at temperatures between 8 and 25 degrees Celsius. The effect of the chemical application in cold weather will be slightly delayed. Typically, 200-300 liters of the working solution are used per hectare.
Precautionary measures
When using the substance, it is important to wear personal protective equipment. This requires a respirator, goggles, and gloves. If symptoms of illness appear, the victim should be removed from the contaminated area, remove protective equipment, and seek medical attention.
How toxic is it?
The product is classified as hazard class 3, meaning it is a moderately hazardous compound.
Possible compatibility
In tank mixes, this composition can be combined with other herbicides and graminicides. It can also be combined with fungicides and insecticides. However, before use, it is important to evaluate the compatibility of the products and their phytotoxicity to the target. This composition should not be used in combination with contact herbicides when treating onions.
How and how long can it be stored?
The medication must be stored in a sealed container in a designated area. The temperature should be between -10 and +35 degrees Celsius. The shelf life is up to 2 years.
Analogues
