Annual, perennial, bulbous and perennial plants have the virtue of growing throughout the year, although they are not exempt from suffering disorders of the habitat in which they live.
Among the most frequent pests and diseases are worms, which can be of various types and affect plants in different ways. It is very difficult to protect plants from these attackers because many of these worms live in the soil and this is how they affect the roots, eating them. This happens with white worms (Anoxia villosa, Melolontha melolontha) and wireworms (Agriotes lineatus). They generally affect ornamental plants and also gnaw tubers and bulbs.
During the spring and autumn more attacks occur while the more extreme temperatures of winter and summer stop them. How to notice its presence? In addition to investigating the soil and observing if there are worms in the soil and among the roots, it is also possible to discover them from the effects on the plants, whose leaves turn yellow until they wither.
Another very common worm is the gray worm (Agrotis segetum, Noctua pronuba) which, unlike the others, attacks the base of plant stems and this is how they dry out. In this case, it is more difficult to detect them because their attacks are at night while they remain hidden on the ground during the day.
If you discover the presence of white and wireworms you can use an insecticide in the soil making several applications. You should choose those that have a component called Chlorpyrifos. In the case of gray worms, you can use a product with the same component or apply one based on pyrethrins. It is recommended to apply the product in the afternoon and repeat it every 15 days.
