Instructions for the use of herbicide Octava, consumption rates and analogues

Herbicides are used to destroy vegetation in a specific area. This group of funds is used in agriculture, and is also in demand by individuals for cleaning their summer cottage or backyard territory. Two-component herbicides, such as Octava, are most effective because of the combination of different chemicals, as well as their targeted complex effects.

Composition, release form and purpose of herbicide Octava

Octave is a mixture of two chemicals that, when actually combined in one bottle, do not physically mix with each other due to the nature of their structures. The oil dispersion resulting from the combination is intended for the treatment of crops of annual and perennial crops.

Octave belongs to a group of selective herbicides, which means a targeted type of action when the treatment is directed against a particular crop.

Octave's composition is a mixture of nicosulfuron and florasulam. The ratio of substances is in the range of the formula: 60 grams per liter to 3.6 grams per liter, respectively. The dispersion is produced in a volume of 10 liters, poured into plastic canisters with a tightly screwed lid made of dense plastic.

Reference! For humans, this drug is not dangerous, it belongs to the 3rd class among systemic pesticides.

The mechanism of action of the herbicide

The main base substance of the drug acts as a blocker of the speed of chemical reactions, the result of which is cell division. Due to the cessation of the production of the central enzyme, the growth of weed plants slows down, necrosis gradually develops, and then the plant dies.

The second element of the composition reinforces the overall effect on protein synthesis, and also aggressively breaks the chain that ensures the development of plants at the cellular level.

Signs of herbicidal action

The herbicidal effect develops over 2-4 weeks, it is possible to predict the reaction more accurately if the characteristics of the treated crop are taken into account. The analysis of the effectiveness of the impact is carried out by time stages.

Each of them has distinctive features:

• at the initial stage, growth processes stop;
• then chlorosis begins to develop, which is expressed in a noticeable yellowing of the leaves;
• after a few days, symptoms of tissue necrosis become noticeable.

Main advantages and disadvantages

Among the advantages of the drug are distinctive features characteristic of formulations based on two components:

• both components provide maximum penetration into plant tissues;
• the oil base helps to create a soil screen that prevents the growth of new seedlings;
• the maximum result is achieved by spending a small amount of funds, since due to the presence of two bases, it is more concentrated;
• the prolonged period of action of the drug is explained by the peculiarities of the structure of the drug;
• the composition is fortified with adjuvants that contribute to the herbicidal effect.

Consumption rates of the drug

To treat 1 hectare, you may need from 100 to 200 liters of working solution. The exact flow rate depends on the type of soil and the weeds to be sprayed.

How to prepare a working solution

The composition for spraying is diluted before direct use. Instructions for preparing the required composition:

1. For 10-20 liters of water, take the required amount of the substance, taking into account the fact that the total percentage of the content should not exceed 50 units.
2. The resulting mixture is stirred using a special device.
3. The spray is filled with liquid.
4. The tank from under the prepared mixture is rinsed with 1-2 liters of water, the resulting liquid is added to the sprayer.

Instructions for using the working mixture

The working solution is poured into sprayers specially designed for treatment with hoses equipped with special tips. Then the sprayer is brought into working condition, the processing of the territory begins.

After processing, the spray tank is washed and dried. The site where refueling took place is additionally washed.

Information! Tanks must comply with established standards, be designed for the application of pesticides.

Precautions when using it

Preparation of the working mixture, processing of crops, refueling is carried out using protective gloves and face masks. To protect clothing from the ingress of chemicals, special polyethylene aprons are used.

Toxicity of the agent

The drug Octava belongs to the group of systemic pesticides. It is a composition that is of little hazard to humans and bees.

Hazard class 3 allows it to be used for processing vegetables, but it is not used near water bodies, so that the substances of the composition cannot get into the water and affect the life of amphibians.

Compatibility

Before using the tank mix, a general compatibility test is carried out. The elements are mixed in a small container. The result is assessed 1 minute after mixing and after 30 minutes from the moment of mixing.

Reference! Drug compatibility cannot be accurately predicted as each case is different.

The physico-chemical properties of the composition may change due to the use of melt, rain or excessively hard water.

How to store the drug correctly

The octave is stored without loss of quality for 2 years from the date of production. In this case, it is necessary to preserve the integrity of the canister, do not additionally freeze or heat the container.

Are there any analogues?

Herbicide Octava, as a two-component selective herbicide, has no analogues in the presence of basic substances, but among the group of pesticides there are similar preparations that are used to treat annual or perennial crops.

Aegis is a systemic preparation that is highly effective against weeds. Promotes the creation of a soil screen, prevents the emergence of new shoots, can replace the Octave when processing corn.
