Juniperus chinensis stricta – preventive treatments against diseases and pests

Hello! I bought Juniperus chinensis stricta 5-6 years ago and they have developed very nicely, already having over 2 meters. Last year in the summer I noticed some white dots and I found out that there are some harmful insects. I sprayed them with insecticide almost all summer. This year I would like to prevent the appearance of these insects since spring. To recommend me a solution that prevents the appearance of some diseases or pests in this species of plants. I also mention the fact that I noticed that in some plants the needles dry from the inside to the outside. Please help me!

Hello, to control a wide range of pests in the spring, it is recommended to apply a systemic insecticide such as Mospilan 20 SG, 3 g. To increase the effectiveness of the insecticide, it is recommended to add an adjuvant such as Break Thru S 240, 2 ml to the spray solution. Spray the solution as finely as possible, so as to achieve a more uniform distribution on the plant. Usually, in conifers, the yellowing and browwning of the leaves at the base of the plant / inside the crown is a normal process, but can also be caused by an affection of roots (excessive moisture, soil compaction, poor drainage, etc. ). It is recommended to loosen the soil at their base and maintain a portion of land without vegetation. It is also important to mention that, before performing a treatment, it is recommended to remove and remove, as much as possible, the dry parts (they must not remain on the ground). After removing the dry branches, in the spring you can consider the preventive application of a cupric fungicide: Champ 77 WG, 20 g. Also in spring, in order to stimulate healthy growth, the administration of a granular fertilizer such as AMN Natural Activ-Bio, 1.5 kg. It improves soil quality, increases stress tolerance and stimulates the absorption of nutrients in the plant, through the content of mycorrhizal fungi. It is applied by incorporation in the soil, in a dose of 50-150 g / sqm. Foliar, during the vegetation period, it is recommended to administer a special fertilizer for conifers such as Fir Fluid, 350 ml which contributes to the prevention of deficiencies, as well as the browning of the needles.
