Main pests in the garden

With the arrival of spring, insects find their optimal conditions of temperature and humidity to proliferate in our plants. To be able to fight them efficiently it is necessary to detect them in time. We explain you which are the most common plagues and how to fight them.

The increase of temperature and humidity stimulates the appearance of insects in our plants. Their quick detection and recognition is essential to carry out the appropriate treatments and prevent them from being killed. Are you able to recognize the most common insect pests in our garden?

LUNGS

They are sucking insects that settle on the green shoots of our plant. They produce a molasses that favors, if we do not act in time, the appearance of fungi (especially bold).

Symptoms: Colonies of aphids (small rounded insects of green, black or yellow colour) appear on the green shoots and in the buds. The leaves may appear wrinkled and yellowish. They usually affect weak plants with nutritional problems.

Control method: To avoid an attack it is important that our plants are strong and not subject to stress. This is achieved with fertilizers and nutritional contributions and a watering schedule adapted to their needs.

When the infestation is not very serious, it can be solved by spraying a homemade mixture of water, soap and alcohol (two spoonfuls of soap and alcohol for every litre of water) and by eliminating the affected shoots. In the case that our plant is very infested with aphids, we must resort to systemic insecticides approximately every fifteen days.

COCHINILLAS

Mealybugs are tiny sucking insects that are protected by a shell and that settle on the leaves, branches or even the fruits of many ornamental plants.

Symptoms: The leaves appear sticky, sometimes white lines can be seen as a result of the molasses they produce. Over time the leaves become yellow, deformed and the plant has a weakened appearance. This molasses also favors the attack of fungi that can be lethal to our plants.

Control method: as in the case of the aphid, early detection is essential to avoid major problems. Initially it may be sufficient to spray a fortnightly solution of soap. In case of more severe attacks, we will have to use systemic and specific insecticides for mealy bugs that you can find in any garden centre.

WHITE FLY

They are small winged insects that appear on the underside of leaves, which is where they lay their eggs. It is a very common pest in spring and in many ornamental plants. Sometimes the white fly can be a transmitter of viral diseases.

Symptoms: yellow spots appear on the leaves and they end up drying out and falling off. In addition the plant presents symptoms of weakening and can stop its growth and normal development.

Control method: To detect soon the attack of white fly there are traps in the market that will indicate its presence. Insects such as ladybirds or earwigs are its natural predators so it is often interesting to maintain its presence in the garden. If the fly population in our plants grows and gets out of control it is best to use a potassium soap.
