Herbicide "Eraser Extra": the method and time of treatment, consumption rates

"Eraser Extra" - This is a drug with which you can easily get rid of annual weeds in the fields with cereals (barley, wheat).

Spectrum of action

By using this herbicide resorted to in case of a serious distribution of various weeds: wild oats, foxtail, canariensis, Aegilops or bluegrass field foxtail, chicken, hairlike or weed-field millet, Field apera, blood crabgrass, volunteer grain corn Multiflori Plevlya and other weeds. The use of any chemical products on the field is appropriate when other (agrotechnical) methods do not help to cope with a large number of weeds in the area.

For weed control, the following herbicides are also used: Tornado, Callisto, Dual Gold, Prima, Gezagard, Stomp, Uragan Forte, Zenkor, Reglon Super, Agrokiller , Lontrel-300, Titus, Lapis Lazuli, Ground and Roundup.

Active ingredient and preparative form

Means effectively acts against weeds by means of fenoxaprop-P-ethyl contained in it, 70 g / l (chemical class of derivatives of 2- (4-aryloxy-phenoxy) propionic acids) and the antidote klokvintoset-meksil, 40 g / l. Eraser Extra comes in the form of a concentrated emulsion placed in special canisters with a capacity of 5 liters.

Drug benefits

  • quickly copes with the elimination of weeds;
  • does not harm crops, because it has an antidote in the composition;
  • applicable at any stage of development of cereals;
  • Compatible with anti-trivial drugs.
Did you know? Modern herbicides, which are derivatives of sulfonylurea, are safer for living organisms than some products of daily use and most drugs. For example, caffeine has an LD50 of 200 mg / kg, aspirin - 1750 mg / kg, while herbicides have an LD50 of 5000 mg / kg (LD50 is the dose of the drug at which 50% of animals die in the laboratory).

Mechanism of action

This herbicide enters the body of plant pests through their leafy plates, then begins to act on the entire weed, gathering at its growth points. The active substance "Eraser Extra" is instantly hydrolyzed with the free acid of phenoxaprop, and this, in turn, slows down the process of biosynthesis of fatty acids in the educational tissues of plants. As a result, attenuation of the formation of membrane compounds in the cells at the growth sites can be observed. Klokvintoset-meksil forces a special detoxification of the active substance in specially grown crops, replacing it with neutral metabolites that can not adversely affect cereals.

Preparation of the working solution and processing

The solution with the use of the drug should be prepared in separate areas, which are then neutralized. This should be done before processing itself, following Instructions for use of herbicide "Eraser Extra":

  • prepare the mother liquor, where the concentration of the substance will not be higher than 20%;
  • wash the sprayer, check its completeness and readiness;
  • turn on the mixer and pour into the tank of the device for spraying a measured amount of the finished composition, and the tank should be filled with water only half;
  • stirring the solution, fill the tank with water completely;
  • the tank containing the mother liquor should be washed a couple of times to drain this liquid into the tank;
  • start spraying the plants on the site.

Did you know? Stories are known facts of the use of herbicides for military purposes. A striking example here is the tragedy "Agent Orange", which was the result of the use of the drug of the same name. Agent Orange is a mixture of defoliants and synthetic herbicides, millions of liters of which the US Army sprayed onto the Vietnamese jungle during the Second Indochinese War in order to find out the location of the Vietnamese army. The consequences of such measures were the development of mental and physical diseases among several generations of inhabitants of the territories who were under the influence of the substance.

Before starting the treatment with plants with a herbicide, it is important to correctly determine the phase of weed development and choose a time to spray, so that the solution accurately affects all unwanted herbs, because this drug seeps into the weeds through the leaves and is not dangerous for those that may develop after spraying. "Eraser Extra" is best used at one of the first stages of weed plants - 2-3 leaves or until the end of the tillering period.

The consumption rate of the herbicide "Eraser Extra" for spraying crops of cultivated grain plants is 0.8-1 l / ha, depending on how clogged the field. Thus, the rate of consumption of all the liquid used for processing is about 200 l / ha. To kill weeds, it is enough to treat the field with this herbicide once.

Spraying can be ground or airborne (using aviation technology). In the second case, the consumption rate of the liquid used is significantly reduced. Ground spraying should take place in this way: the mixture is applied uniformly to plants from a distance of 50 cm. First, the top of the weeds is sprayed, then the middle part, and, last of all, the bottom.

Important! It is possible to carry out work on the treatment of fields, without fear of the dangerous effects of the drug on the human body, 3 days after the first application of the composition to the treated area.

Impact speed

"Eraser Extra" begins to fight with grass weeds and stops their negative impact on crops of cultivated plants very quickly - already on the second day after spraying. Signs of drug exposure to weeds:

  • signs of chlorosis appear on the leaves of the pests;
  • in rare cases, the acquisition of leaves of anthocyanin (blue or red) coloration by the leaves is observed;
  • weeds wither and dry quickly.
If you are not a supporter of the use of chemicals in your garden, then you can cope with weeds with the help of folk methods.

Period of protective action

The weather depends on how quickly the field is freed from the negative impact of weeds (usually within 15 days after treatment). Fresh, untreated weeds begin to appear 2-3 weeks after the procedure. The drug does not work on them, but until that time the cultures are getting stronger and becoming resistant to the negative effects of weeds.

Compatibility with other drugs

"Eraser Extra" can be combined with anti-venomous herbicides that fight perennial weeds ("Galion", "Gorgon", etc.). Derivatives of such preparations are phenoxy acids, clopyralid, sulfonylureas, etc.

Important! Before mixing herbicidal agents in the tank, it is necessary to carry out a chemical check for their compatibility.
When preparing the mixture, you must first mix each herbicide in turn with water and only then mix the solutions, i.e., do everything so that the preparations themselves do not mix directly.

Toxicity

The description of the herbicide "Eraser Extra" cannot be complete without mentioning the toxic effect of the substance. As is known, all chemical compositions are divided into 4 classes, depending on the level of toxicity and negative impact on living organisms: from extremely dangerous to low-hazard. The hazard class is determined by the MPC, CVIO, the average dose, after which it is applied to the skin or into the stomach, the inevitable consequence is death. "Eraser Extra" belongs to the 3rd class of toxicity. This means that it is moderately dangerous.

When resorting to the use of this drug, you should observe all precautions and act according to the rules of herbicide use: protect the respiratory system, eyes, and skin from the effects of the drug.

First aid for poisoning

Eraser Extra, if the drug is not used properly, can have a negative effect on the skin, eyes or the entire human body, so it is important to know how to avoid undesirable consequences of contact with the herbicide.

  2. When the drug gets into the organs of vision, they should be washed with plenty of running water.
  3. If a part of the substance or solution has somehow penetrated into the internal organs, it is necessary to urgently consult a doctor. Before the victim is provided with qualified assistance, he must drink activated carbon with a large amount of water: 1 g of activated carbon per 1 kg of body weight. After that, it is necessary to induce vomiting.

"Eraser Extra" is a substance that quickly copes with cleaning the fields with cereals from weeds of various species. To work with this herbicide, as with any other, it is necessary, wearing protection. A single spraying of the plants with this preparation is enough to quickly wean the weeds and stop the negative impact on the cultivated plants. However, in order to maximize its benefits, it is necessary to choose the right processing time. Cereal crops are usually sprayed in the spring with the help of a special device for spraying the solution with a substance or using aviation if the area of ​​crops is very large.
