Weed control chemicals: a review of the best drugs

To grow a crop in the garden, the summer resident has to carefully look after the seedlings during the entire growing season. In addition to pests and diseases for cultivated plants are dangerous weedsreducing the yield by half. Not a single vegetable will grow on the beds overgrown with weeds - they will crush it.

The contamination of the summer cottage indicates the negligence of the owner, about his ignorance of the peculiarities of the development of cultivated plants. Weeds damage not only plants but also the soil. There is a minimum of benefit from them, but much more harm.

What is the harm to garden crops from weeds?

What is the harm to garden crops from weeds?

All agricultural crops suffer from weediness of crops, and the point here is in particular the development of weeds:

  1. Weeds need a lot of moisture to grow. Growing in the garden, wild oats, wormwood and other herbs dry out the soil, which is especially harmful during the hot summer. At the same time, dryness of the upper and middle layers of the soil leads to the death of vegetables, and weeds, on the contrary, thrive. Their root system becomes powerful, going two to three meters deep into the layers of the earth.
  2. Together with moisture, weeds consume many nutrients. Phosphorus, potassium, nitrogen are removed from the soil. For development, weeds need more elements than cultivated plants.
  3. In places where weeds thrive, pests and fungal infections spread. The meadow moth lays its testicles in the wormwood, and caterpillars it is switched to vegetables. Through wheatgrass and nettle, garden plants are infected with a rust fungus. Carriers of potato cancer include weeds of the Solanaceae family.
  4. Reduce the yield of vegetables grasses entwining plant stems. It is difficult for garden crops to grow; they lie down without producing fruit.
  5. The quality of vegetable products decreases, as the amount of valuable substances in tubers and root crops decreases due to weeds. And vegetable seeds cannot germinate due to soil contamination.

Weeds are characterized by high adaptability to the environment. More than three hundred species of herbs grow in regions from west to east. Their fertility, vitality does not allow cultivated plants to develop, and a person to receive rich harvests of vegetables.

Herbicides - what are they?

Herbicides - what are they?

If earlier they fought with weeds by hand, pulling them out or cutting them with a hoe, now chemical preparations have come to the rescue of the summer resident, herbicides... This word of Latin origin means "I kill the grass." Chemicals are based on acid compounds and their derivatives.

Herbicides, when applied to weeds, have different effects. By destroying the cell membranes, substances lead to necrosis, desiccation or soaking of plant tissues. Due to the toxic effect, the growth of weeds is slowed down or too accelerated, which leads to their death.In addition, herbicides have a negative effect on the processes of photosynthesis of herbs, inhibiting them.

In order for chemicals to rid the garden of weeds, they must be applied correctly, under special weather conditions.

The substances in the base of weed control drugs act in different ways. Some can destroy all plants, while others - a certain species. Contact herbicides are produced. They are applied to the leaves of plants with a brush. Many types of chemicals are diluted in water and watered with working solution on the garden bed. If the preparation is applied dry, the soil is moistened before use.

Weeds are cultivated before they sprout, as well as after they appear in the garden. All types of herbicides are selected in accordance with the purpose of treatment, having carefully studied the instructions.

Review of the best weed control drugs

Review of the best weed control drugs

To understand the variety of weed control drugs, you need to listen to the opinions of farmers:

  • Butisan is based on metazachlor, which, getting into the soil, poisons the roots of weeds. The chemical is used to treat the beds after sowing cabbage, radish.
  • The volatile herbicide Treflan is used to control annual cereal weeds and dicotyledonous - wild oats, woodlice, veronica. The drug is embedded in the ground to a depth of ten centimeters before planting seedlings tomato, cabbage.
  • Zenkor helps to keep crops clean. It penetrates the plant both through the roots and leaves and destroys weeds during the germination period. Thanks to the use of the drug, garden crops will be protected from weeds for a long time.
  • The systemic herbicide Prometrin protects vegetable crops throughout the growing season. The destructive effect on weeds begins from the second day of germination of grass seedlings.
  • Weed plants are sprayed with Roundup during their intensive growth in the second half of summer. The drug is suitable for potatoes, grapes.
  • Tornado is known for coping with malicious weeds: wheatgrass, bindweed, thistle. Even a small drop of the chemical on a stem or leaf will kill the entire plant. The drug is used in any weather; it remains in the soil for a long time.
  • Gezagardom destroys weeds growing in fields with potatoes, beds with carrots, peas, garlic.

All herbicides have their own methods of application, but they must be applied according to the instructions.

When and how can chemicals be used?

When and how chemicals can be used

Weeding the beds is not always effective in killing weeds. Single plants can be pulled out and put in a compost pit, but dense rows of weeds are best destroyed with herbicides. And herbs like wheatgrass cannot be removed by hand. The more they pull it out, the more actively it will grow.

As soon as the weeds begin to hatch near the vegetables, they begin to process herbicides... Vegetable seedlings are covered with foil or plastic bottles, and weeds are sprayed with fast-acting preparations such as Roundup. After three days of action, the weeds will dry out. They are removed from the garden, and the vegetables are watered.

General herbicides should be used in the fall when the crop is harvested. Systemic chemicals are applied starting in spring throughout the summer. But you can not process the plantings if there are two weeks left before harvesting the fruits.

After processing the beds, twenty days later, digging the soil is carried out, removing the rhizomes of the weeds.

Spraying of weeds with chemicals is carried out in calm and cloudy weather, preferably after rain. When there is a lot of dust on the leaves, the chemicals do not penetrate well into the weed plant.

Before starting the fight against weediness in the garden, they study the features of the use of this or that herbicide, its effect on cultivated plants. Some chemicals can destroy flowers and grass on the lawn. When spraying them, the toxicity class of the agent in relation to humans, birds, domestic animals is taken into account.

Precautions when using herbicides

Precautions when using herbicides

During the application of herbicides, summer residents must adhere to the instructions, the dosage of the drugs. The treatment is carried out in protective clothing, glasses, gloves. If the solution gets on open areas of the body, they are washed with plenty of water.

After completing the procedure, the clothes are washed, and the hands are washed with warm water and soap.

In case of poisoning with herbicides, a person may feel dizziness, weakness, and nausea. If you experience unpleasant symptoms, you need to urgently seek help from a specialist or cleanse your stomach with activated charcoal.

Weed chemicals are stored in a dry place out of the reach of children and animals. The working solution is prepared before the spraying procedure; its excess should not be poured into water bodies.
If the consumption rates of herbicides are met, then their harmful accumulation in cultivated plants will not occur.

Prevention of weeds in the garden

Prevention of weeds in the garden

Preventing weeds in your garden is easier than fighting them:

  • Weeds will not have room in the garden if the vegetables are planted more closely to each other. You can build compact beds by raising them above the ground or lowering them below the level of the garden.
  • Frequent loosening of the soil around the planting will keep weeds from developing. Exposing the roots of grasses leads to their drying out and the death of weeds.
  • A popular way to prevent weeds is to mulch the plantings. A layer of fallen leaves and straw five to ten centimeters thick is used as mulch. It is not necessary to place mulch close to the stem of the vegetable plant, otherwise the plant will not have enough air. It is useful to use a newspaper with a black and white print as mulch. Sheets are laid along the plantings, pressing them to the ground with pebbles.
  • The area underneath is covered with a black plastic material. cucumbers, peppers, tomatoes... Vegetable seedlings or seeds are planted in the holes made. The plastic will keep the weeds from growing and the vegetables will feel comfortable. After harvesting the fruit, the material is removed.
  • The active growth of weeds begins when the crops are harvested in the fields. You can avoid their growth by sowing the vacated areas with winter rye. The fallow lands are sown with buckwheat. The weeds will then have no room, they will not appear.
  • To prevent weed seeds from spreading around the garden, in the fall the grass is harvested, burned, and the soil is treated with herbicides. Bird feeders can become a source of weeds, so they should be placed at a distance of ten to fifteen meters from the garden.

Regular destruction of weeds will allow you to clear the garden, make it comfortable for the development of cultivated plants.

I don't really like the "chemistry" in the garden, but you won't be doing weeding all the time either. I prefer herbicides of contact action, which are applied only to the leaves of weeds, so as not to destroy the necessary plants.
