In our gardens and orchards, we meet many species of aphids. Although small, the average size of their body is 2-4 millimeters, the aphids cause great damage. They are found on fruit species, in vegetables, medicinal and ornamental plants, trees and shrubs. In addition to attacking various plant species, leaf aphids reproduce rapidly. They have many generations, and this is one of the reasons for their large presence. A good Gardner should always know the ways to get rid of aphids.
Aphids feed on young and succulent plant parts. They are mostly found on young leaves, and they can also cause damage to buds, young stems, flowers, fruits, and roots. They cause damage by sucking on plant tissue. During the diet, various deformations of the affected parts occur, which at the same time serve as a shelter. Endangered plants are physiologically weak because aphids use nutrients for their nutrition.
In addition to direct damage, aphids are indirectly even more dangerous because they transmit different plant viruses (about 100 different viruses).
Aphids have great reproductive power, so they quickly form huge colonies on attacked plants. However, their abundance is most influenced by temperature and humidity. The optimum temperature for aphids is 20-28 degrees and the humidity should be above 60%. Rain showers wash away aphids and cause them to collapse on the ground. High temperatures and dry periods cause a decrease in the number of aphids.
Insects as enemies of aphids
Many insects are natural enemies of aphids, and they are used in the diet. To attract these insects to your gardens and orchards you need to build hotels for beneficial insects and thus create favorable conditions for them. Many predators reduce the population of aphids: ladybugs, horned flies, predatory weevils… In addition to predators, parasitoid wasps are also useful.
Birds use aphids as food
Many small birds feed on aphids: terns, sparrows, small bushes and others. To attract birds to your garden, orchard, or garden, you need to set up cottages, feeders, and feeders for them. Provide bird feeders during the winter to provide birds with a constant source of food.
Nettle as a home remedy to get rid of aphids
The nettle preparation also showed good results. To use it you need 1 kg of fresh nettle or 200 g of dried nettle, which you should pour with 10 liters of water. Then the nettle should be allowed to stand for 12-24 hours, not longer, because in this case, the nettle loses its insecticide properties. The preparation should then be treated and the resulting solution treated with the affected plants. This preparation has been successful in combating green aphids, while black ones have proved less effective.
A solution of tomato leaves as a home remedy to get rid of aphids
You can make this solution by chopping and dipping 2-3 handfuls of tomato leaves into 2-3 cups of lukewarm water. Allow it to stand overnight. Drain in the morning and pour it into a spray bottle. Spray the whole plant with this solution, keeping in mind that most of the aphids are on the lower part of the leaf where they are least seen. Toxic ingredients from tomato leaf will destroy aphids, and most importantly they are not dangerous and harmful to humans.
Soak thirty fresh leaves of wormwood or 5 grams of dry leaves in one liter of water. Allow a few days to stand, drain and spray with this solution the plant attacked by aphids.
Garlic preparation as a home remedy to get rid of aphids
Garlic preparation has proven to be very effective in combating black aphids. To prepare it, you need to grind or crush 200 g of garlic and cover it with 1 liter of warm water. You should leave this mixture for about 5 hours. Then dilute one cup of the preparation with 10 liters of water.
For a tobacco preparation, you need to pour 400 g of tobacco leaf with 10 liters of warm water. Allow soaked tobacco to stand for at least 3 hours, then drain and apply as a home remedy to get rid of aphids.
When buying a plant, carefully inspect it before you bring it home. If you notice herbs despite all the precautions, wash the plant with a spray of water and then spray with a natural remedy that you made yourself instead of some harmful insecticide. The use of natural remedies is especially important in plants that you keep in your home and use as spices or teas.
