Every day, faced with complex plant diseases (especially ornamental) and a host of pests, experienced gardeners came to the conclusion that it would be much more correct to deal with them not with the help of chemicals that adversely affect the vital activity of healthy plants and the person himself, but using insecticidal plants. Their effectiveness has long been proven in practice, so the use of insecticidal plants to combat diseases and pests of ornamental vegetation is fully justified.
In this article, we will consider a number of insecticidal plants, methods for preparing special decoctions and infusions from them for watering and spraying, as well as in which cases it is necessary to apply a particular plant.
Belena Black. The roots and leaves of black hen are collected and harvested in early spring or autumn. Then they are prepared according to a simple recipe: 0.5 kg of dried leaves or 1 kg of dried plant is insisted in a bucket of water for 12 hours. The infusion is filtered and then about 30-40 g of soap is added to it. Infusion is used for spraying plants. It is an effective remedy against cicadas, larvae of sawflies, ticks, aphids and leaf-eating caterpillars.
Tegetes or Marigolds. The collection of plants for the preparation of the infusion is collected in its entirety, during flowering. The volume of half a bucket of dry plant is filled with water. This remedy should be infused for at least two days. Next, the infusion is filtered and 40 g of soap is added to it. It is effective against aphids and rot. Also in this infusion, you can disinfect the bulbs of gladioli before planting. Marigolds also work well in live form. To get rid of nematodes, marigolds should be planted between other flower crops in the area of your summer cottage.
Dope. A poisonous plant that should be used with extreme caution. But, at the same moment, dope copes pretty well with bugs, ticks and aphids. Dope infusion is prepared according to the same recipe as black bleached infusion. The collection of the plant for the preparation of the drug occurs during flowering - the entire aerial part, as well as in the fall, when the young shoots of datura and rhizome are collected.
Calendula. The collection of this insecticidal plant for infusion occurs during flowering. The recipe for the infusion is the same as during the preparation of black bleached.

To do this, it is not necessary to spray the plants with infusion, you can just plant a calendula among the decorative plants of your garden.
Potatoes. To prepare the drug, only the tops not affected by the diseases are used. It is necessary to take 0.6 kg of tops or 1.2 kg of green mass of the aerial parts and insist for 4 hours in a bucket of water.

The broth itself should be stored in a sealed vessel and in a dark, cool place. You can use the decoction without adding water if you mix 13 g of concentrate, 4 g of soap and mix in one liter of water. It is most often used to control sucking and gnawing insects, young caterpillars, aphids, whiteflies and thrips.

Next, the lime solution is cleaned of sediment and poured into it a solution of copper sulfate. The result is a blue liquid that is immediately ready for use. A fairly effective remedy for gray rot, powdery mildew and rust;
- Copper-dusty mixture. Another popular drug that has long been used among summer residents. It can be prepared quite simply - initially a solution of 25 g of soap per 1 liter of water and separately a solution of 2.5 g of copper sulfate in 50-100 g of water are prepared. Then the solution of vitriol is slowly poured into a soap solution and get the necessary tool;

To prepare it, you will need to take 300 g of wood ash, pour it with a liter of water and insist 1 day. After this period, the solution must be filtered and immediately used.
Each of the above recipes has been repeatedly used by experienced summer residents. It is they who recommend timely treatment of plants to combat pests and diseases. This is the only way to achieve good flowering, harvest and complete preservation of the decorative properties of plants.
A mandatory recommendation of professionals is also the observance of all safety rules when working with insecticidal plants and the preparation of chemicals for processing plants. Some of them can be toxic, and therefore unsafe for human health.
