What can I use to combat the rose sawfly?
Hello Paola and welcome to the "Questions and answers" section of our website. To combat the sawfly, he can use different tricks and different products. The sawfly is a 5-6 mm long insect in the adult stage that parasitizes plants of the Rosaceae family. Harmful phytophagous, it eats the leaves when it is in the larva stage, causing serious damage to our roses.
The most frequently used remedy is the chemical fight and is done in particular by those who work with plants. The treatment is applied during the first stages of development of the larva, in the first and second stages. In the home garden, on the other hand, a careful owner should check the leaves in April and May and promptly eliminate those that are characterized by the presence of the parasite's eggs or present this parasite in the larval stage.
All fruit crops suffer from pest attacks, and pears are no exception in this respect. Do not take any means to protect the trees, at least in a reckless way, as this can lead not only to the death of the crop, but to the entire tree.

Coloroderm is dangerous because it hibernates in fallen leaves and in the bark of fruit trees, and after the defeat of the kidneys it can still live on a tree for a month, eating leaves already in bloom.
therefore for parasite prevention in autumn it is important to remove all the leaves from under the tree and burn them. Also it is necessary to take care of the whitewashing of the logs.
How to spray apples from flowers? For this purpose it is recommended to use "Chlorophos" solution, stirred at a concentration of 0.2%.

In fact, during the first larval stages, it may be sufficient to just remove the attached leaves and manually eliminate the insects and eggs to reduce the risk of infestations.
In the case of an infestation that has already occurred, we must distinguish whether it is an ornamental plant or an edible plant.

But, despite all its beauty and unpretentiousness, improper care and disease can inflict serious damage on the plant. The article will discuss how to properly care for junipers and the means of fighting pests.
Young junipers have needle-shaped leaves, which vary with age, depending on the variety, and come in the form of small scales. Juniper has a powerful root system, but it grows extremely slowly, due to this feature, the growth period of some representatives can last up to 1000 years.
Tip: Don't forget that most of them are slow-growing plants, so you need to cut them carefully.
Juniper has a fairly strong wood, resistant to rotting and the harmful effects of insects. But despite this, plants have common diseases and pests that need to be addressed.
Ephedra suffers from insect invasion, perhaps even stronger than deciduous trees. After all, the needles grow for many years, and if they are damaged, the plant takes on an untidy and morbid appearance. Therefore, it is so important to detect and prevent the spread of parasites in a timely manner.
