The use of pesticides in agriculture. What can replace the pesticides?

Of course, it's impossible to do without pesticides in the garden. They are used to fight insects, fungus, harmful microorganisms and weeds. However, since the use of these substances in any case is harmful to health, it is necessary to try to minimize it. Below in the article we will talk in detail about what can replace pesticides.

Classification of pesticides

At present, dacha and residents of rural areas in the gardens use such varieties of chemicals:

• Herbicides. This group is used to kill weeds in beds. Most often, two of their types are used: treble trees (for drying stems and roots) and defoliants (to remove leaves from branches). The frequency and duration of work with pesticides of this type depends on the variety of weeds. Usually, one or two treatments are sufficient to remove unwanted grass.
• Fungicides. They are used to cure cultivated plants from fungal diseases.
• Insecticides. Used to rid the garden or garden of harmful insects.
• Zoocides. This species is designed to combat mice, shrews, moles and rats.
• The apes. A separate group of pesticides used to fight specifically with aphids.
• Repellents. Used to repel insects.

Next, consider what can replace the pesticides of each of these specific groups.

We minimize the use of herbicides

Of course, it is difficult to find a natural replacement for herbicides. No decoctions and tinctures of weeds in the garden can not be destroyed. The only way out here is hand weeding. However, it is possible that someone will use one rather interesting method of combating weeds in carrots and parsley. These two plants are not at all afraid of kerosene. In contrast to clogging their wild grasses. Therefore, the first "weeding" can be carried out with the use of this substance. Dilute 100 g of kerosene in a 10-liter bucket of water and sprinkle the carrot that has just risen. The result will be noticeable the very next day. Carrots remain unscathed, young shoots of swans and other weeds will die. Of course, kerosene for health is also of little use. However, until the spring of it, neither in the soil, nor in the plants themselves, there will be nothing left.

How to replace fungicides

Next, let's see what can replace the pesticides, designed to combat fungal diseases of cultivated plants. Garlic is one of the most effective ways to get rid of this kind of problems. For example, to control powdery mildew and late blight, you can use this infusion: 25 g of garlic is crushed thoroughly and 1 gallon of water is added to the slurry. Insist the resulting mixture during the day. Then it is filtered and used for spraying plants.

Also against ordinary fungal diseases, you can use ordinary wood or straw ashes. Another means of fighting this type of infection is infusion of dried marigold flowers (half a bucket of half a bucket of water + 40 grams of laundry soap, 2 days). In addition, the field horsetail helps against the fungus (21 g per liter of cold water, boil for 30 minutes, drain and add water to 4.5 liters).

How to replace insecticides

About the plants used instead of fungicides, we talked quite in detail. Now let's look at what can replace the pesticides, designed to get rid of pests. Very effective means against them are the same garlic, as well as tobacco. The latter can be used, for example, to control the sawfly larvae (400 g of tobacco per 10 liters of hot water, 2 days insist, and 40 grams of laundry soap). Also, to get rid of this pest, you can use an infusion of ash (3 kg per 10 liters of water, withstand 2 days).

Aged mixture of garlic and water very well helps against a weevil on strawberries, raspberry beetles, and medlennes. 200-500 g of this burning vegetable is thoroughly crushed. Then gruel pour 3-5 liters of hot water. The resulting solution is insisted for five days.

Against berry bugs, caterpillars cabbage whitewash, cruciferous fleas, fruiting females, herbivorous moths can use a decoction of tomatoes. For this, 4 kg of fresh green stepsons are ground, poured with ten liters of water and insisted for 3-4 hours. The mixture is boiled for half an hour. The broth is filtered and used for spraying.

Against onion, carrot and cabbage fly can be used coniferous powder. For its production, small spruce twigs together with needles are passed through a meat grinder, dried and powdered plants, and also the soil next to them.

Against slugs, you can use ordinary cement. They pollinate the soil under the plants and between rows at the rate of 50 g per 1 m ² . Such treatment should be done in the morning or in the evening.

Combating aphids by folk methods

Such types of pesticides, like aphids, can also be replaced by infusions and decoctions of plants. To control aphids usually use garlic, marigold or mustard-conifer mixture. In the latter case, 2 tbsp. Spoons of mustard insist in water for two days. Then the volume of the mixture is brought to 10 liters and it adds 1-2 st. Spoons of pine extract.

You can also use nettles against aphids. To do this, its fresh topsoils are ground and insist in cold water for 24 hours. It helps from this harmful insect and bitter wormwood. To prepare a means of aphids, 2-3 kg of dry grass is diluted with water and boiled for half an hour. Then the broth is filtered and supplemented to 10 liters.

Zoocides

The use of pesticides in agriculture, designed to combat rodents, can also be minimized, at least in their personal summer cottage. For this, a method is frequently used, such as growing plants in the vegetable garden, which are not tolerated by mice. For example, in the spring in places of a special congestion of rodents it is necessary to plant coriander. Very much these pests also do not like red elder, mint and coriander. May help from mice and detergent powder with a strong smell, placed in the caps around the site.

In addition, experienced gardeners to get rid of these rodents advise to cover up the trunks of bushes and trees with a cut from the celandine. The bark of young trees can be protected from mice by simply wrapping the trunks at the bottom with cut plastic bottles with holes in them.

Pollution of the soil with pesticides can lead to nothing good, of course, can not. Meanwhile, there are many people's means of fighting insects, fungus and rodents.
