Kaptor's herbicide: instructions for use, mechanism of action, analogues

Cultivation of sunflower without the use of herbicides today has become almost impossible, since it will not be possible to get rid of weed vegetation mechanically. Captora herbicide is an excellent plant protection product and, as the instructions say, helps to cope with a wide range of monocot and dicotyledonous weeds.

Composition and formulation of the herbicide

The substance refers to a two-component broad-spectrum herbicide that is used after the emergence of cultivated plants. It effectively resists various vegetation due to improved technological characteristics and a more concentrated structure.The drug consists of 2 main components:

imazamoxa - 16.5 g per 1 g/l;
imazapira - 7.5 g/l.

They belong to the class of imidazolinones, capable of providing complete control over weeds sprouting in the cultivated area.

Kaptora herbicide is available as a water-soluble concentrate in ten-liter and five-liter canisters.

Advantages and disadvantages

The herbicide has distinctive features, with the help of which it adequately proved itself among consumers and occupies a leading position in the ranking of similar drugs:

quick penetration into the vegetative organs of weeds and instant action;
guaranteed protection against the emergence of new representatives and parasites throughout the growing season of the cultivated plant;
possibility to use during the phase from 2 to 8 true leaves;
ease of use.

The drug has practically no drawbacks, in addition to a large number of restrictions on the use.

Spectrum and mechanism of action

Imazamoxa is a systemic pesticide aimed at controlling grain and broadleaf weeds in crops of cultivated plants. The substance penetrates the roots, leaves, enters the conducting system and spreads through the phloem and xylem of the plant, accumulates in the meristem. The component acts as an inhibitor of the synthesis of such an important enzyme as acetolactate synthase.

Due to the decrease in the level of this organic matter, the number of amino acids decreases, the synthesis of proteins and nucleic acids is suspended.

The plant stops growing after 5-6 hours after treatment, after which the destruction of the main tissues begins, the process of wilting starts.

Imazapyr is a contact herbicide. The mechanism of action is to disrupt the synthesis of isoleucine and valine, essential nucleic acids. The component partially penetrates the plant tissue, while the main part remains on the surface and prevents cell division and further growth.

The spectrum of herbicide action extends to cereal monocots and many dicots.

It is noteworthy that the tool is one of the most effective in the fight against broomrape - a parasitic plant that causes significant damage to sunflower crops.

Calculation of consumption for different plants

The herbicide consumption rate per 1 ha of sunflower fields is 1-1.2 liters.

Preparation of working solution

The solution is prepared on the same day that processing is planned. To do this, the tank must be half filled with water, add the right amount of fungicide, mixing thoroughly, add water so that the container is filled to the brim.The norm of the working fluid with a large amount of weeds should be at least 250 liters per 1 ha.

Instructions for use

Processing is best done in the evening or morning on a calm, dry, cloudy day.

For the best effect of the herbicide, the air temperature should vary from 14 to 25 degrees.

It is worth refraining from processing if the cultivated plant is under stress, due to drought, high humidity or a sharp change in temperature.

Safety rules

It is forbidden to use the product near water bodies. It is necessary to warn the owners of neighboring plots in advance about the place and time of processing. It is necessary to protect the skin and mucous membranes from the ingress and negative effects of the substance with the help of protective clothing.In case of acute poisoning, see a doctor.

Further use of sunflower green mass as livestock feed should be considered by the relevant authorities.

Means toxicity

The drug belongs to the 2nd hazard class and can cause serious poisoning. Negatively affects the life of fish and insects in the first days after application.

Compatibility

Kaptora herbicide is a highly effective and potent drug, so it cannot be combined in tank mixes with other weed control products, as well as complex and mineral fertilizers.
