Herbicides are widely used in weed control on plantings and crops. They are continuous and selective action, namely the latter are used in agriculture. "Ovsyugen Express" - one of the safest means to combat dicotyledonous weeds. Due to its low toxicity, it does not harm the environment and its inhabitants, which made it popular among farmers.
Spectrum of action
"Ovsyugen Express" It is effective not only against oats, it is a broad-spectrum herbicide that effectively fights with all cereal weeds of the dicotyledon class: oats, chicken millet, metlyug ordinary, millet semi-flowering, meadow bluegrass, etc.
Drug benefits
The drug has several advantages among them:
- Selectivity The drug affects only the weed tissue and does not harm the cultivated plants, even in case of overdosing.
- Non-toxic to humans, bees and animals. Slightly toxic to birds.
- It does not accumulate in the soil and in plant tissues, it is completely decomposed into components.
- It affects the weeds at different stages of the growing season, starting from the two-leaf phase.
- Available in the form of an emulsion, which is very convenient to use.
Did you know? Dosage plays an important role in the use of pesticides. For example, dichlorophenoxyacetic acid in small dosages stimulates the growth of weeds, which it fights in higher concentrations. A sulfonylurea drugs in excess doses destroy crops.
Active ingredient and preparative form
"Ovsyugen Express" refers to systemic herbicides. The peculiarity of systemic anti-grass herbicides is in the mechanism of action, the essence of which lies in the disturbance of plant metabolic processes: biochemical reactions and physiological processes. This principle of operation is one of the most effective, since it immediately stops the growth of the plant and blocks the mechanisms of recovery.
The systemic herbicides penetrating into the vascular system of weeds can also be attributed to "Folicur", "Ground", "Ovsyugen Super", "Stomp", "Zenkor", "Tornado", "Gezagard", "Pivot", "Cowboy" and "Titus".The active ingredient of the drug fenoxaprop-P-ethyl - selective herbicide overwhelming synthesis of essential amino acids. Means gets inside a weed, being absorbed through leaves and a stalk. Then it breaks down into metabolites, one of which - phenoxaprop acid - directly reacts to inhibit the synthesis of fatty acids. As a result, the reaction is disturbed, and cell division in the zones of weed growth soon stops, which leads to its death.
"Ovsyugen Express" produced in the form of an oil, water emulsion or emulsion concentrate. Usually it canisters with a capacity of 5 and 10 liters.
When and how is the treatment and application rates carried out
For maximum effect Ovsyugen processing is carried out after the majority of weeds have risen. Since the drug does not accumulate in the soil, its effect extends only to ascended plants, and if you hurry, you may need to re-process.
The consumption rate per 1 ha is from 300 to 400 l of the working solution, depending on the degree of weed infection. The working solution is a mixture of the concentrated Ovsyugen Express emulsion and water, which is prepared at the rate of 0.01 part of the preparation for 1 part of water. So, 400 hectares of emulsion will be required for processing one hectare of winter wheat, and 200–300 g for processing 1 hectare of spring wheat. 
Important! "Oxygen Express" more suitable for large farmer fields than for small private farms, because the consumption of the drug is very small, and the shelf life of only 3 years.The treatment is carried out early in the morning or in the evening, when sun activity decreases. Despite the fact that the active substance of the herbicide fenoxaprop-P-ethyl is stable at an air temperature of 50 ° C, in a spray form under active UV radiation, it can turn into toxic fumes that are dangerous to humans and animals. The weather should be dry and windless.
Impact speed and period of protective action
After treatment, the first damage on the weeds can be seen already after 3-5 days, and complete death occurs in 12-15 days. Herbicide has no prolonged action and does not harm the seeds of grass weeds. That is, in the fight against the second wave of weeds, if there is one, the previous treatment will not help. 
The half-life of the active substance is 3 weeks in acidic soils and 7-10 weeks in alkaline or neutral.
Hazard Class and Precautions
"Ovsyugen" assigned 3rd class of danger to humans - moderately dangerous.
- Lethal dose in contact with skin and mucous membranes - 500-2500 mg / kg.
- The lethal dose in the stomach - 150-5000 mg / kg.
- The lethal concentration in air is 10 mg per cubic meter.
- On the part of the gastrointestinal tract: the defeat of the upper part of the stomach, nausea, vomiting, abnormal liver function.
- From the side of the central nervous system: headache, impaired coordination, clouding of consciousness, coma.
- On the part of the respiratory tract: respiratory failure, pulmonary edema and fibrosis.
Did you know? It is much easier for a person to poison herbicides by inhaling poisonous fumes or spilling onto their skin, rather than swallowing them. The fact is that only 30% of the herbicides caught in the digestive tract are absorbed, the remaining 70% are excreted by the kidneys unchanged. But the mucous and human skin absorb from 70 to 90% of the poison.
In handling chemicals, the following are the safety measures:- Changeable clothes. Take care of a suit that you will use only when working with chemicals: these clothes should not be washed or stored with everyday wear. Classic uniforms when working with poison dispensers: headgear, vacuum glasses, thick gauze on the respiratory organs, outerwear made of coarse fabric with long sleeves and pants, a rubber apron or a material of similar properties.
- Check the condition of the sprayer using water.
- Spray in the morning or evening, subject to the absence of rain and wind.
- You can not eat, drink, smoke during processing.
- Make sure that during the processing on your site and adjacent areas there are no people.
- If the herbicide is likely to get on vegetables or fruits - do not eat them for the next 3 days, then thoroughly rinse under running water before use.
- Herbicides should not be handled in children, pregnant or lactating women, people who are hypersensitive to components or diseases of the respiratory tract.
- After treatment, neutralize the sprayer tank with a 5% solution of washing soda or a gum of wood resin. To neutralize the residues of the herbicide, the container should be filled with soda solution for 3-6 hours, and ashes porridge - 12-24 hours.

Compatibility with other pesticides
Ovsyugen Express is compatible with sulfonylurea, phenoxy acid and clopyralid herbicides according to the instructions for use. But in any case, it is recommended to test for physical and chemical compatibility with each specific drug.
Important! It is advisable to carry out the treatment with systemic herbicides in two cases: when the crops are heavily contaminated (weeds 3/4 of the grass height) and when other means, such as weeding and sheltering between the rows, with an opaque material, do not help.
Shelf life and storage conditions
The shelf life of "Ovsugen" is 3 years from date of manufacture. Depressurization of the canister does not affect storage conditions and shelf life.
The pesticide should be stored in the same way as other pesticides of the 3rd class:
- The preparation cannot be stored together with food, household items and in premises.
- The temperature in the storage room should not fall below zero and rise above 50 ° C. Left in the cold, the tool loses its properties.
- It is necessary to store in the original container or in a similar container.
- "Ovsyugen" - a highly effective concentrated drug of systemic action, safe for crops, humans, animals and bees.
- Convenient to store and use, very economical consumed: cans of 5 liters is enough to handle 11 hectares.
