The aphids (Aphididae), are insects of 3mm of green, yellow, brown and black color. They feed on the sap that they suck from tender stems, leaves and flower buds. The leaves appear yellowish spots, the stem and flower buds roll and deform. The aphids secrete a sticky substance that attracts the ants and the fungus fumaginas spp., Or black powder. They usually appear in dry environments, especially in spring and summer.
These are several ecological remedies to prevent the aphid and to combat its plague.
It is important to keep the area in good conditions of cleanliness, as well as irrigation, since the aphid likes dry climates, so we should not neglect irrigation during the spring and summer months.
10 ecological remedies to prevent and combat the aphid
1. Garlic: To make a garlic-based repellent at home, we will simply boil a liter of water with five crushed cloves of garlic for half an hour. We let the water cool down and we strain it; the result we will spray on the plant.
2.Ajenjo: Wormwood is a plant with insecticidal and repellent effect, but its effect is not powerful enough to plant the plant in our urban garden and wait for it to act, it is much better to plant it, and when it grows prepare the following solution: Boil 40 gr. of absinthe leaves per liter of water and let rest 24 h.
3. Infusion of onion: Like garlic, onion is a natural food that used against fungi and aphids. Chop a medium onion per liter of water and boil for 5 minutes. Once cold it can be applied.
4. Purine or nettle maceration: Nettle is a plant from which we normally flee, but there should always be a little bit in our urban garden. Nettle is a good insecticide, stimulates the growth of plants, and strengthens your immune system. The mixtures of nettle maceration are different in cases of preventing, fertilizing or curing the plants, but to give you an idea: macerate 100g of nettle in prefloration in 1L of water for 15 days, the plants must be submerged, and the mixture must be removed. When the water is already dark and the smell of fermentation appears, we strain the mixture. To apply it, we must dilute the liquid in 100ml of solution per 500ml of water. It is sprayed on the plant or soil to prevent the attack of insects, fungi and aphids, strengthen the plant and fertilize.
5. Horsetail: 100 g of fresh plants are soaked in 1 l of water for 24 hours. Then boil a few minutes, let it cool and filter. It is diluted in water in 1/5 proportion. It should be applied in dry and sunny weather, from spring to summer. Fumigate directly on the plants.
6. Pest Repellent Plants: Some insect pests are repelled by the odor or chemical composition of other plants. To repel aphids we can plant basil, sage, cilantro, rosemary, garlic, lavender, lemon balm and mint.
7. Plants that attract beneficial insects: The flowers of some plants attract beneficial insects for our garden, such as the parasitic wasp, spiders, chinitas or ladybugs, bees, butterflies and other pollinators. This helps keep pest control and all our flowers are pollinated so that they are then transformed into rich fruits. Try with: Borage (Borago officinalis), Mint, Dill, Yarrow (achillea millefolium), Calendula, Marigold and Basil.
8. Tanaceto: The tanceto or leaves of San Pedro (Tanacetum vulgare or Tanacetum cinerafolium) has a high pyrethrin content. It is used as a general insecticide. We will make an infusion with 300 grams of tansy and 10 liters of water. Let it sit for 10 minutes. Strain and apply on the plants.
9. Chamomile to reinforce and stimulate their resistance to pests and diseases Chamomile is one of the plants that activates the microbial population in the soil or compost. We will need 50 grams of chamomile and 10 liters of water and we make an infusion that we will let stand 15 minutes. Strain and apply undiluted on the plants.
10. Soap solution: Dilute 1 tablespoon of neutral soap in 1 liter of water and spray on the plant.
