This is how you fight lashes effectively!

Thrips, also called “storm beasts” or “August beasts,” are small (1-2 mm) biting sucking insects. However, they can be identified by their long feathery, non-membranous wings. Therefore, it is impossible to mix them with flour axes or harmful axes! Nevertheless, like the latter, the lashes are very difficult to remove from the plantings after it has settled there. It can then cause significant aesthetic damage and weaken your plants. And for good reason: they hide under the leaves to eat their juice. Gardeners must therefore be vigilant and act quickly to prevent this insect and its larvae from multiplying. This achieves biological control of these unwanted pests without the use of chemical insecticides.

Who are we dealing with?

These insects belong to the genus Thysanoptera, which consists of about 3,000 species of ciliate. However, western flower thrips (Frankliniella occidentalis) are the best known. Very productive, this slender insect is very common in greenhouses, conservatories and houseplants. However, it also occurs outdoors when the environment is hot and humidity is low. Usually populations explode From May to September. Hard to spot with the naked eye, you need to rely on the silver spots they leave on the plants, or bring you a good magnifying glass to identify them under the leaves of the contaminated plants.

What are the risks to plants from thrips infestation?

They empty the contents of plant cells after piercing plant tissues. In this case, the bite releases toxic saliva. This then gives birth grayish spots and ugly color changes. The leaves begin to wither and the young shoots become distorted, which can lead to poor growth, even necrosis. The flowers go through deformation at the level of the petals. In most cases, the plant does not die. However, he will more susceptible to disease cryptographic and viral (tanned tomato, etc.). It can also reduce yields.

Plants most affected by these small beasts:

Those creatures such as greenhouse plants and indoor plants. However, some plantations are more sensitive to it!
-Garden vegetables: broccoli, cabbage, pumpkins, beans, turnips, onions, leeks, radishes, tomatoes and radishes.
– Fruit: strawberries and raspberries
– Plants: azaleas, begonias, chrysanthemums, orchids, roses
– Fruit trees, olive trees and shrubs in the ornamental garden.

-Introduce a crop rotation to disrupt the reproductive cycle of this species.
-Maintaining the spread by maintaining a humid and airy atmosphere. Spray water on the plants. If the plant is not too afraid of fungal diseases, also spray water under its leaves. In addition, you can spray these pests with a powerful water jet from the garden hose or in the shower to remove these small plant phage insects.
-Factory garlic, clover or flax plants at the base of the plants they want a protective repellent effect.

And what care when lashes are installed?

-Place blue sticky traps, if possible related to pheromones. This color attracts lashes, and these traps make it less likely to accidentally catch beneficial insects in the garden.
– Invite helper insects that are their natural predators : mites (Amblyseius cucumeris), tapeworms (Chrysopa carnea), nematodes, insects…
-Use garlic soup soaking two cloves of garlic per liter of water for 24 hours. Then add a tablespoon of dishwashing detergent or better, black soap and canola oil. Then spray contaminated parts. Repeat every 5 days for a month.
-You can also simply dilute 4-5 tablespoons of black soap per liter of water.
-Sprinkle diatomaceous earth or dilute sweet orange essential oil to spray the plants under attack.
– After treatment, perform a plant your plants in a clean pot with new, healthy planting soil.
