Instructions for the use of the herbicide Semeron, mechanism of action and consumption rates

It rarely happens that when growing crops do not have to deal with the appearance of harmful insects or diseases. Sometimes it is impossible to cope without the help of chemicals. In this case, the herbicide "Semeron" can help.

Composition, release form and purpose of the drug

Semeron herbicide is usually available in the form of water-soluble powders or emulsion suspension. It can also be sold as a concentrated solution. This substance contains desmethrin.

The chemical is used to kill most of the weeds that grow in cabbage beds. But it can be used for other crops as well. Suitable for both annual and perennial weeds.

The mechanism of action of the weed control

After the beds have been treated with a chemical, the active substance begins to penetrate the plant tissues through the root system and foliage. The chemical gradually spreads throughout the plant. Then the weeds begin to wither and gradually die. The visible effect is achieved a few days after the spraying (provided that it did not rain after the procedure).

Application advantages

The benefits of this herbicide include:

1. The duration of the effect (the protective effect after spraying the plants lasts from 5 to 10 weeks).
2. Helps to get rid of most of the weeds growing on the site.
3. Easy to use.
4. Long shelf life.
5. After about 6 weeks, the active substance is completely removed from the plant tissues that have been treated.
6. Slightly toxic to humans and mammals.
7. Economical consumption.

Despite all the advantages, the Semeron chemical has one very serious disadvantage. The substance that is part of the product is dangerous and toxic. With frequent use in large quantities, it leads to environmental pollution, so it is recommended to use the product only in extreme cases, when there are a lot of weeds on the site and other means cannot cope with them.

Before buying a herbicide, it should also be borne in mind that the Semeron chemical is not included in the State Register of pesticides and agrochemicals that are permitted in Russia.

Consumption rate of the herbicide "Semeron"

The working solution is prepared based on the ratio of 1.5-2 kg of substance per 1 ha. The most optimal consumption of the suspension when spraying the beds is from 400 to 600 liters per 1 hectare of the plot. One sq. m you need 0.4 liters.

Methods for the preparation and use of the working solution

Before processing, you need to pay attention to the weather forecast. If it should rain in the next few days after treatment, it is better to transfer it to another day.

According to the instructions, spraying is recommended in the morning (from 7 to 10 am) or in the evening, after sunset.

The optimum air temperature at which the herbicide will be effective is from +18 to +25 degrees. It is best if the weather is warm and calm. Do not spray plants if they have dew on them. It is also forbidden to use a herbicide if the cabbage is damaged by a cabbage fly at the time of spraying. It is not recommended to spray the beds in very hot and rainy weather. If it is not possible to carry out the procedure at another time, after waiting out the heat, then for several days you need to water the beds abundantly every day.

The drug is most effective in the early stages of weed growth. To prevent their appearance, seedlings are sprayed after 1-2 weeks of planting in open ground. Seed crops are sprayed after 4-6 full leaves appear on the seedlings.

Herbicide safety

When using the herbicide "Semeron" you need to be extremely careful. This agent is very dangerous and, if used incorrectly, can lead to poisoning. Before the procedure, you need to wear glasses and a mask so that the solution does not get on the mucous membranes. It is also recommended to spray the beds in fully closed, heavy clothing.

If the solution gets into the eyes or on the skin, immediately rinse the affected area with plenty of running water. In the event that after a while irritation, redness, itching or any other unpleasant symptoms appear, an urgent need to consult a doctor.

After the procedure, at least 6 weeks must pass before the cabbage is edible.

Compatibility with other products

It is not known what the combined use of several herbicides can lead to. If it is necessary to use several herbicides at the same time, it is better to take a break of several weeks between treatments. The longer the break, the better.

How to store the herbicide correctly
