Herbicides for continuous weed removal

Herbicides are chemicals used in agriculture that allow you to quickly get rid of weeds. If you translate the word, it comes from the herb - "plant", cide - "destroy." According to the method of action, there are selective and continuous (non-selective) herbicides. In the article you will find information about continuous action herbicides and about the features of their use.

general description

As the name implies, continuous herbicides destroy all green plants, including cultivated herbs. They, as a rule, affect the greens in contact, destroy the membrane and lead to necrosis or the rapid death of vegetation.

Herbicides of continuous action are used less and less often, selective substances are more popular. Nevertheless, they are still actively used both in agriculture, gardening, and at industrial facilities, in construction, near airfields and railway tracks. In agriculture, they are used both professionally, in large farms, and in small farms and in suburban areas. Chemical composition of herbicides are:

• organic;
• inorganic.

Depending on the period of use, continuous herbicides are divided into:

• pre-emergence;
• post-emergence;
• universal, used in different periods of vegetation development.

Depending on the characteristics of the application, there are herbicides:

• soil (affect the roots, seeds, sprouts);
• leafy (affect the aboveground part of the grass).

Forms of release of herbicides:

• water solution;
• granular composition;
• powder mixture;
• suspension.

Kinds

All anti-weed drugs according to the method of exposure to herbs and method of application are divided into 2 groups:

• contact;
• system.

Contact

Contact agents affect leaves and stems. by direct contact with them. They disrupt the normal life processes of the grass and lead to its death. However, after their use, new sprouts may grow back, since the roots remain unaffected.

Substances resistant to moisture. They are used if it is necessary to quickly and massively destroy vegetation. Are especially toxictherefore, it is prohibited to use them in private farms.

Systemic

Systemic substances penetrate the vascular system of herbs and thus spread to all organs, provoking their quick death. At the same time, both aboveground and underground organs perish.

Such herbicides of continuous action are especially effective in the treatment of weeds plantations with a strong root system, as well as against perennial weeds.

Features of selection and use

In order to choose the right drug, it is necessary to clearly understand in which territory it will be used, against which weeds, and what effect must be achieved.

As a rule, chemicals with continuous systemic action are suitable for use:

• on agricultural land - in the fields in pre-sowing and post-harvest time, on summer cottages;
• in gardening - for processing between rows, including vineyards;
• on non-farm land - along runways, railways, power lines, highways, highways, in city parks;
• in shipping - to destroy algae that prevent the passage of vessels.

In world history, facts are known that chemicals were used as one of the military tactics to destroy enemy crops and deprive him of food or a negative impact on the health of a nation.

Depending on the herb for which the chemical substance is calculated, several methods of its use are distinguished:

• to get rid of annuals, as a rule, apply pre-sowing treatment, during the growing season and after harvesting;
• perennials are exterminated by the post-harvest method or by periodic dressing between the plants.

When using anti-weed chemicals, it is necessary to strictly adhere to the dosage recommended by the manufacturer, as well as recommendations on how to behave with chemicals.

Eating food and beverages during the use of chemicals is strictly prohibited. You can not work after drinking alcohol. After applying the herbicide substances, you should shower, wash your hair and drink a glass of milk.

It must be remembered that herbicides are drugs that have a prolonged effect, so there is no need to hurry with repeated processing.It is better to wait for the effect for 2-3 weeks.

It should not be forgotten that continuous plants also kill cultivated plants, so if the treatment is carried out during the growing season, a thin-stream sprayer should be used.

Herbicides of continuous action (with the description and a photo)

The group of non-selective herbicides includes some organic substances (Roundup, Glifogan, Arsenal), as well as almost all inorganic.

Consider the 10 most commonly used.

1. "Arsenal". The drug has a broad spectrum of action. He is considered one of the best for embedding in industrial areas. Very good at handling virgin soil. The substance that is part of it, is able to act on some plants for 4-5 years.
2. "Glyphosate". A feature of this drug is that with its systemic use in the phase of active growth of plants and after the final harvest, there is a slowdown, and with time - and a complete cessation of amino acid synthesis. It is good for treating areas where weeds should be completely destroyed. It is used in vineyards, on tea fields, in fruit and citrus orchards.
3. "Hurricane Forte" - relatively new herbicide of continuous action. He has proven himself in the fields with monocotyledonous and perennial crops, as well as in the destruction of shrubs. It is applied in gardens, vineyards, on industrial and city objects.
4. Roundup. A universal remedy, which, falling on the leaves of a plant, moves down it and, reaching the root system, kills it. It can be applied in a wide range of temperatures. Suitable for use on the dacha.
5. "Tornado 500" - herbicide continuous action, which stands out from the entire line of drugs that has in its composition an increased concentration of the active substance. Therefore, it is more economical - it requires a smaller amount of funds to process a large area. The drug belongs to the universal substances that have the same effect on annual and perennial crops. It is applied at a wide range of temperatures. Can be used in the country.
6. "Torch". An effective and inexpensive drug. Due to the fact that it penetrates into the vascular system of plants, it kills them completely, both the ground organs and the root system.The drug is popular because it effectively acts against weed crops that are included in the hydrophytic group (sedge, cattail, etc.). After its application it is possible to plant cultivated plants in a week. The drug does not settle in the soil, does not affect the crop rotation and is suitable for exposure to any grass. It is allowed to apply at the dacha farm.
7. "Grader" - A continuous herbicide containing an increased concentration of a chemical imazapir. It affects almost all weeds. It has high efficiency - a week after its use, all herbs die completely. It is applied both in the industrial purposes, and in personal farms.
8. "Napalm". Suitable for the destruction of all types of weeds. In sunny weather, the effect of the application comes after 3 days. On average, to achieve complete destruction of weeds, it will take a week. Cultivated plants can be planted in cultivated land after 3 weeks.
9. "Typhoon". Suitable for getting rid of all types of weeds. It does not possess soil activity, which means it can be applied before planting any crops. It affects all plant organs.If it is properly applied, following all the recommendations of the manufacturer, it is possible to avoid harm to the soil, humans and animals.
10. "Octopus". Contains an increased amount of the active substance - glyphosate (potassium salt), which allows its use in small doses. At the same time, it does not possess soil activity and has no effect on crop rotation. Suitable for all types of weeds, easily copes with perennials, killing all organs, including roots. It can be used at positive temperatures up to the first frost.

Benefits of using

The use of herbicides has several advantages:

• reduction of manual labor costs;
• low financial costs;
• high effectiveness against most weeds;
• ensuring a significant increase in the yield of grain, legumes, industrial and fodder plants;
• the duration of the protective action against weeds - some can prevent them from occurring before the harvest period, and there are those whose toxicity lasts until spring;
• there are drugs that can be applied to the soil along with sowing or fertilizing, which reduces the time and financial costs;
• maintaining the required level of moisture in the soil.

Today, the use of herbicides is an effective and fast method of clearing the land from weeds, better than which science and industry have not yet invented. Despite the fact that completely safe preparations for humans, animals and the environment have not yet been invented, for more than 50-year history of development in this area, low-toxic drugs have been derived. The range of anti-weed chemicals today is huge. In order to cause the least damage and not feed the relatives with crops with "chemistry", it is necessary to strictly adhere to the dosages and frequency of tillage, which are prescribed by the manufacturer.
