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

This herbicide is resorted to in the event of the serious spread of various weeds: oats, bristles, canaries, aegilops or bluegrass, field foxtail, chicken, hairy or weed-field millet, field broomstick, blood rosary, corn fluids, and multicolored pearls. The use of any chemicals in the field is appropriate when other (agrotechnical) methods do not help to cope with a large number of weeds in the area.

Active ingredient and preparative form

Means effectively acts against weeds with the help 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 cans 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 cereal crops;
• compatible with anti-trivial drugs.

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" instantly hydrolyzes 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 must 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,moreover, 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 the liquid into the tank;
• start spraying the plants on the site.

Before starting the treatment of plants with a herbicide, it is important to correctly determine the phase of weed development and choose a time for spraying 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 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 rate of consumption 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.

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 by weeds of anthocyanin (blue or red) color is observed;
• weeds wither and dry quickly.

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.

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 compounds are divided into 4 classes, depending on the level of toxicity and negative effects 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.
