There are natural methods that solve the problem of parasites in flowers and plants. Avoid the use of pesticides!
For those who like to take care of their houseplants and have a knack for gardening, it’s not uncommon to encounter a strange situation. Small insects that don’t harm humans, but are dangerous to plants, often find their way into the leaves and stems. These insects, known as aphids or lice, can be a serious obstacle for those who have invested time, effort and passion in growing their home garden. The presence of these pests is a common occurrence and can easily undo all the hard work that has gone into creating a beautiful indoor oasis. Fortunately, the problem of plant pests is not an insurmountable obstacle. In fact, there are several methods and tricks that can be implemented to remove these parasites in a simple and effective way. Below is a comprehensive guide that includes everything you need to know.
Plant pests: what are they?
There are numerous species of insects that can pose a threat to plants, and aphids are among the most well-known. These hemipterous insects are usually tiny, between 1 and 3 millimeters in size and have a delicate body structure. They may or may not have wings and have mouthparts capable of piercing and/or sucking liquids. Aphids are harmful to plants because they feed on the sap of cultivated and wild plants, and they are especially harmful to fava beans and apple trees.
Having roses can become a nightmare because they tend to spread and affect other nearby plant species. Detecting an aphid infestation is a relatively simple task that can be accomplished with a quick visual inspection. These pests eat the sap of plants, which affects the overall health and vitality of the foliage, including color and shape. A cursory examination of the shoots and leaves with the naked eye is usually enough to identify the problem. However, it’s important to note that its appearance can be deceptive to growers. While they usually appear in shades of brown, yellow, or black, some aphids can be green, making them harder to spot because they blend seamlessly with the leaves they attach to.
The risks
Existen varios riesgos que los entusiastas del cultivo casero deben tener en cuenta, y los pulgones no son los únicos. Las orugas son otro riesgo que no debe subestimarse, ya que pueden devorar rápidamente plantas o ramas enteras. Por lo general, comienzan mordisqueando una hoja pequeña y luego se abren camino hacia otras partes de la planta y especímenes cercanos. Este tipo de plagas prefiere el follaje tierno y dulce, especialmente las hojas de albahaca y lechuga. Las orugas son difíciles de detectar porque a menudo se mezclan con la planta de la que se alimentan y tienen un color verde que es exactamente idéntico al de su huésped. Las chinches representan una amenaza real para las plantas, especialmente la chinche apestosa asiática, que es la mayor amenaza. A pesar de su pequeño tamaño, esta plaga puede tener efectos catastróficos, especialmente para los agricultores. Si está disponible, es importante centrarse en los cultivos frutales como melocotones, peras y manzanas. La chinche apestosa asiática se destaca de su contraparte europea porque no solo ataca las hojas, sino también las flores, verduras y frutas. El insecto causa necrosis al succionar la savia de las plantas y, en última instancia, contribuir al marchitamiento de la planta. La infestación de la chinche apestosa en la base de los cogollos puede hacer que la planta se seque, lo que tiene un impacto profundamente negativo en el éxito de la cosecha. Vale la pena señalar que la chinche apestosa asiática también se ha extendido por toda Europa.
Cochinilla, arañas rojas y mosca blanca
No hay que pasar por alto los efectos de la cochinilla, una planta parásita que sólo puede reproducirse bajo ciertas condiciones climáticas. A este diminuto insecto le gustan especialmente los climas cálidos y húmedos y tiende a desaparecer cuando llueve. Sin embargo, la propagación de cochinillas a lo largo del tiempo puede provocar una disminución significativa de la integridad estructural de la planta. Las moscas blancas, que son nativas de las regiones tropicales, prefieren climas cálidos y húmedos, similares a las cochinillas mencionadas anteriormente.
They are a common problem in greenhouses and areas with lakes and are known for the damage they cause to lemon plants. However, for those with small gardens with ornamental plants such as begonias, geraniums, or orchids, whiteflies can be a big problem. The formation of honeydew, a sugary substance that turns the leaves where the whitefly perches yellow, is a clear sign of its presence and can cause the leaves to fall off. Red mites, while harmless to humans, are actually tiny mites that fall into the category of harmful insects and can cause significant damage to the fruits and ornamental plants they feed on to survive. It is important to note that animals are not the only threat to plants, as they can also be significantly affected by fungal infections. An example of this type of disease is powdery mildew, also known as white powder, which manifests as a powdery substance that coats the plant, similar to talcum powder. This condition is usually limited to outdoor garden plants and does not affect houseplants. Powdery mildew is caused by spores of a specific type of fungus called powdery mildew, which is invisible to the naked eye and can be spread by the spread of wind.
Avoid the use of pesticides
At first glance, it may seem logical to use chemicals such as synthetic pesticides to effectively eliminate pests and prevent their further growth. Farmers use chemical agents to protect their crops from animals that pose a significant threat to their economic stability, and the use of these agents is strictly regulated by law. The problem lies in the well-known negative effects of these substances, which affect different levels of society. These pollutants are incredibly harmful to the environment and can leach into the soil and subsequently into groundwater. This poses a significant threat to all living organisms, especially over a long period of time. The negative effects of pesticides, especially systemic ones, on the human body have been repeatedly confirmed due to their residues remaining in agricultural and food products. Fortunately, there are safe and effective natural remedies that we can use from the comfort of our homes, and the next chapter will outline some of these options.
Natural treatments to eliminate plant pests
One of the most popular ways to fix this problem is to use neem oil, a natural extract obtained from pressing the seeds of the neem tree. The main ingredient in this oil is azadirachtin, which effectively eliminates certain pests such as aphids while also preventing the presence of pollinating insects such as bees, which are essential for the overall health of flowers and plants. Another useful raw material in pest control is Bacillus thuringiensis, which is readily available on the market.
