If you have ever wondered why your plant is covered with a white powder similar to dandruff or because it is sticky, probably the answer is that one of the most common garden pests is inhabiting them.
What are the most common pests in the garden and orchard?
When insects begin to invade your plants, you can remove them by hand or with chemicals that are generally sold in powder or liquid and come in a variety of brands.

Thrips usually cause a lot of damage to the flowers, as they pierce and scrape the petals.
When you inspect your plants, try some small, black and elongated bugs and, if you find them, fight them by spraying the plant with a pesticide that contains pyrethrin, malathion or this effective Calypso AL polyvalent insecticide that also works for whitefly and aphids.
When you shake the plant that is infected by whiteflies, they form a cloud of insects that can be annoying and very difficult to eliminate.
They thrive in warm and dry places, and usually deposit their eggs and larvae on the underside of the leaves, which can be seen as small, oval and white scales that excrete molasses and produce a black fungus. Spray your plant twice a week with a pesticide that contains pyrethrin or malathion.
The aphid is one of the most common pests in the garden.
There are different colors of aphids : green, black, pink and yellow. They can be winged or wingless, depending on their maturity. When they begin to multiply, they can damage your plant quickly and attack the new shoots to suck the juice and thus feed.
While a mild attack of aphids can be fought with a little warm water, ideally spray the plant once a week for three weeks with a pesticide containing malathion, pyrethrin or permethrin.
Cotonet or cottony mealybug
The adult mealybugs appear crushed and are covered by a woolly white powder. They usually attack the new outbreaks and cause serious damage. Remove the plant from the pot carefully and procure the insects that gather around the roots.
If found, remove root mealybugs by dipping root mass in a solution containing malathion. Repeat the treatment two or three times with an interval of 10 days or apply the insecticide Volck Miscible .
Although these insects are not only a serious problem, they can be very annoying and damage the roots of plants that develop in peat compost.
Typulas are very similar to mosquitoes and feed on rotten matter. To combat them, apply pyrethrin and water the compost with a metaldehyde solution. Repeat the procedure twice with an interval of seven days.
They look like brown, pale and transparent warts, and are usually found on the stems and on the back of the leaves. The newborn cochineal is flat and small and feed on the juices of the plant.
When the invasion is very large, the new shoots deform and the stems can be completely destroyed. Spray with malathion, dimethoate, Miscible Volck or Calypso AL.
The slugs and snails that attack indoor plants are different from those in the garden, since they are small and hide in the minimum hole or crack they find and leave during the night.
They feed on large pieces of leaf, so you should use Ferramol to remove them.
Mites are so tiny that they are usually invisible to the naked eye. In addition, they are located at the back of the leaves. However, when the plague is widespread you can see some creatures of straw color and some fabrics on the floor.
