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

Herbicides are used to kill vegetation in a specific area. This group of products is used in agriculture, and is also in demand by private individuals for cleaning their dacha or backyard areas. Two-component herbicides, such as Octave, are most effective due to the combination of different chemicals, as well as their targeted complex effects.

Composition, release form and purpose of the herbicide Octave

Octave is a mixture of two chemical substances 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 connection is intended for treating crops of annual and perennial crops.

Octave belongs to the group of selective herbicides, which means a directed type of effect, when treatment with the product is directed against a specific crop.

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

Reference! This drug does not pose a danger to humans; it is classified as class 3 among systemic pesticides.

Mechanism of action of the herbicide

The main base substance of the drug acts as a blocker of the rate of chemical reactions that result in 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 death of the plant occurs.

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; the reaction can be more accurately predicted if the characteristics of the crop being treated are taken into account. Analysis of the effectiveness of the impact is carried out in time stages.

Each of them has distinctive features:

• at the initial stage, growth processes stop;
• then chlorosis begins to develop, which is expressed in 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, the distinctive features characteristic of formulations based on two components are noted:

• both components provide maximum penetration into plant tissue;
• the oil base helps create a soil screen that prevents the growth of new seedlings;
• the maximum result is achieved by using a small amount of product, 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 enhanced with adjuvants that contribute to the herbicidal effect.

Drug consumption rates

To treat 1 hectare, 100 to 200 liters of working solution may be required. The exact flow rate depends on the type of soil, as well as the characteristics of the weeds that need 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 that the total percentage of content should not exceed 50 units.
2. The resulting mixture is stirred using a special device.
3. The sprayer is filled with liquid.
4. The tank from under the prepared mixture is rinsed with 1-2 liters of water, and the resulting liquid is added to the sprayer.

Instructions for using the working mixture

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

After treatment, the sprayer tank is washed and dried. The area where refueling took place is additionally washed.

Information! Tanks must meet established standards and be designed for the use of pesticides.

Precautions when using it

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

Toxicity of the product

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

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

Compatibility

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

Reference! The compatibility of drugs cannot be accurately predicted, since each case is individual.

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

How to properly store the drug

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

Are there any analogues?

Octava herbicide, as a two-component selective herbicide, has no analogues in terms of 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 drug that is highly effective against weeds. Helps create a soil screen, prevents the emergence of new shoots, and can replace Octave when processing corn.
