Plants that help protect crops from pests and diseases

In order to combat pests and diseases of plants, we offer you herbal infusions and decoctions, which are safe for humans, compared to persistent and potent pesticides.

However, when applying these infusions, it should be remembered that they all contain alkaloids, glycosides, saponins, essential oils and other compounds. Therefore, some precautions should be taken when working with protective plants. For example, after collecting plant materials, preparing preparations from them, it is necessary to thoroughly wash hands and face with soap, do not smoke, do not take food during work. The dishes used for the preparation of the compositions must be cleaned with wood ash or rinsed with a solution of soda ash, rinsing repeatedly with water. To create a kind of "drug bank", raw materials can be dried for future use by storing them in paper or cloth bags.

To destroy gnawing and sucking pests, decoctions and infusions are used, separated from plant debris. Treatments are best done in the evening or early in the morning, repeating them at intervals of 7-10 days. Since herbal preparations are active only in direct contact with insects, to improve adhesion to leaves in infusions and decoctions before spraying, it is necessary to add loose soap at the rate of 8-10 tablespoons per 10 liters of solution. Such formulations can be used both for disinfecting seeds and for spraying plants of different ages.

In particular, for pre-sowing disinfection, it is recommended to soak the seeds in aloe juice diluted with water (1: 1) for six hours. After that, the seeds are washed with clean water to restore flowability and dried. Aloe juice is also effective in the fight against spider mites on plants. For this, 150 g of crushed leaves are poured with 1 liter of water, infused for 7 hours, filtered and sprayed three times after five days.

Marigolds, which are widespread and beloved by many growers, help to get rid of aphids on berry fields. In this case, fresh or dry crushed plants are placed in an enameled ten-liter bucket (1/2 bucket), top up with warm water to the brim and infused for two days. Spraying is carried out only until the first signs of ripening of berries and, if necessary, renew them after harvesting. To protect against nematodes, marigolds are planted next to the protected crop (strawberries, phlox).

It is interesting that, in addition to the main (food) purpose, potatoes and tomatoes are effective defenders of neighbors in the beds from aphids, ticks, herbivorous bugs, cabbage whitebird caterpillars, moths and flies, apple moth, meadow moth, rape sawfly larvae, cruciferous flea beetles, for flea beetles sawfly and moths, against all types of caterpillars.

Then the contents are rubbed well and filtered through cheesecloth. 2 liters of concentrate are diluted in 10 liters of water. The solution is prepared only on the day of its use.

In the fall, you can prepare dry tops of tomatoes and potatoes for future use.

Among our "green defenders" there are plants that, by emitting odorous substances, phytoncides, heal the air, protecting themselves and their neighbors from pests. These plants include most of the plants already described above, as well as: bird cherry, wormwood, red elderberry, mint and many others. Such plants are simply useful to plant next to other pests affected. Phytoncides are destructive for many microorganisms, insects, pathogens. For example, it has long been noticed that where bird cherry grows, there are no flies. If elderberries or mint grow in the garden, then even mice and rats scatter from them.

When planting tomatoes in the aisles of gooseberries and currants, the latter do not affect moth, glass and sawflies. If you plant a batun onion between the rosettes of strawberries, a weevil will not land on this plantation. In addition, by picking off onion feathers for food, we promote the spread of onion phytoncides, which reduces the infection of berries with gray rot. Marigolds, nasturtium, emitting powerful streams of phytoncides, are good defenders against pests of fruit, berry and vegetable crops. If they are planted between berry bushes or next to tomatoes, cabbage and other vegetable plants, then the butterflies of many pests will fly around them.

Thus, knowledge of the properties of protective plants you are already familiar with will save your garden and vegetable garden from uninvited guests and get the maximum yield from your green pets, without harming your health. Good luck.
