Prima herbicide is a product whose use requires extreme care and caution. Failure to comply with proportions, contact with skin and respiratory organs - all this can lead to a detrimental effect of the substance on both the condition of crops and human health.
Composition and release form of the drug Prima
Before purchasing pesticides, experienced owners of crop areas are interested in the composition of the drug. Herbicide Prima is no exception. Information on the exact composition and proportions of active ingredients can be found on the packaging.
Any specialist knowledgeable about herbicides will note that Prima contains two strong components: florasulam and 2.4 D ether. It is thanks to them that the product is highly effective.
There are two types of Prima herbicide, each of which has a list of advantages and uses:
- herbicide Prima Forte;
Prima Forte is used to treat areas affected by all types of weeds
- Prima SE herbicide is a product whose use is permissible only after sowing grain crops.
Prima SE has no harmful effects on plants, destroying only weeds
The form of the substance is unchanged, regardless of the area of application. The drug is available in the form of a water-soluble emulsion. Thus, the product is easy to prepare for use, as well as to treat crop areas with it. You can purchase the herbicide in 1 and 5 liter containers, which allows you to profitably calculate the required amount of product.
Principle of operation
The work of the substance is explained by a simple principle, but at the moment of spraying its active components do a lot of work. After applying the drug to the area affected by weeds, its composition begins to interact with the cells of the plant that needs to be destroyed. The components penetrate its leaves and stop the process of cell division. The plant stops absorbing oxygen on its own and slowly dies. The components of the herbicide rapidly spread over the entire surface of the weed, preventing it from developing.
The composition of the drug is created in such a way that it can only affect weeds. The herbicide is safe for cultivated crops. Therefore, this method of weed control has many fans.
Prima has a high level of action and a wide spectrum of damage, due to which most of the weeds die
Advantages and disadvantages
Like any other weed control product, Prima herbicide has its advantages and disadvantages. Users evaluate this drug differently, each time adding new provisions to the list of “pros” and “cons”.
The undeniable advantages of Prima herbicide include:
- wide range of effects on weeds;
- high efficiency in the fight against all types of weeds;
- long period of action;
- efficiency does not depend on the stage of weed growth;
- has the ability to rapidly disintegrate when released into the soil;
- low level of influence on grain crops;
- unpretentiousness to weather conditions;
For many fans of the herbicide Prima, there is no worthy list of disadvantages of this drug. However, it is worth highlighting that the product can be toxic to humans if precautions are not taken. The herbicide also affects the growth of crops if the conditions for preparing the mixture have not been properly met. However, all these shortcomings are caused by the careless attitude of the gardener, and therefore often do not deserve the attention of responsible gardeners.
Preparation of working solution
It is not difficult to prepare a high-quality herbicide solution; it is only important to follow the instructions. Before use, shake the contents of the container. The composition of the drug may form a light sediment, which dissolves when shaken.
Then the emulsion must be diluted with water in a ratio of 5 liters of substance per 15 liters of liquid. The solution must be mixed and poured into a container suitable for spraying the drug. It is important to note that the product must be prepared and applied immediately after opening the package, since the herbicide cannot be stored under such conditions.
Instructions for use of the drug Prima SE
Prima SE is used after sowing, therefore its use must begin after the fifth leaf appears on the grain crop. Treatment can be carried out both in the morning and in the evening. The first results of the drug will be noticeable a day after use.
As a rule, Prima SE is used once a year, but in some cases the number of doses needs to be increased. If necessary, treatment is repeated 14 days after the first dose of the drug.
Typically, the herbicide is used on young weeds, but its range of effects allows it to destroy adult plants as well.
Prima for wheat
The main difference between Prima for different types of crops is the dosage. For each crop, it is necessary to determine its own amount of the drug. Wheat is a delicate crop, so some herbicide application features apply to it.
During the early development of weeds in the spring, wheat, spring barley and rye are treated with a herbicide, the dose of which varies from 0.4 to 0.6 l/ha. If bedstraw predominates among harmful crops or etching did not take place earlier, then 0.6 l/ha of the drug is administered.
Prima herbicide for corn
Corn has its own conditions for using the Prima herbicide. If the crop is in the 3-4 leaf phase, then the dosage of the drug is in the range from 0.4 to 0.6 l/ha.
However, if the corn has reached phase 6-7, and bedstraw predominates among the weeds, then it is necessary to introduce 0.5-0.5 l/ha of herbicide. In this case, the drug will be most effective in the fight against harmful plants.
Duration of protective action
The degree and duration of the protective effect are indicators that entirely depend on the type of weed, as well as on the climatic conditions accompanying the process of getting rid of harmful grass. On average, it takes about three weeks from the moment of using the drug to the final result. Usually this figure is not exceeded. The protective effect of the drug is ensured throughout the growing season.
Compatibility with other tools
In general, Prima herbicide can be combined with any type of fertilizers and preparations. The product interacts well with nitrogen-containing substances and various growth stimulants. However, before using the solution, it is important to test for compatibility with other drugs in a separate container.
Security measures
In order to provide yourself and others with complete protection, you must use the herbicide while wearing special clothing. To do this, you need not only to wear a suit that covers all surfaces of the skin, but also to protect your respiratory and vision organs with a respirator and goggles.
Do not spray the herbicide near fire or in places where children are present. It is also not recommended to use the product at the time of pollination of the plant, since the composition can cause significant harm to insects.
Analogs of Prima herbicide
The modern market offers many options for analog products that are comparable in effectiveness to the Prima herbicide. Among the most successful drugs that can be used as a replacement are Prius, Disulam, Agent and Prime.
Prima is not recommended to be used in parallel with analogue means, as this can harm crop plants
Conclusion
Prima herbicide is one of the best products that is used by both experienced and novice gardeners. To get the maximum effect from using the drug, you must take a competent approach to its use and do not forget to comply with the instructions.
