Spruce-larch miteis an aphid that lives on larch and spruce trees. This pest hibernates hidden in cracks in the bark, in spring it distorts the needles of larch, and in summer it covers the shoots with white waxy secretion.

Spruce-larch mite: (1) galls formed on the shoots, (2) dried galls left by pests, (3) white bloom visible on the needles in summer
Spruce-larch oysteris the so-called double-house aphid. It needs two hosts in its life cycle. Larch is the primary host and spruce is the secondary host. This pestcreates the so-called gallsThey are oval, cream-colored, up to 12 mm long. They resemble tiny cones or pineapples.As a result of the feeding of the spruce-larch larvae in May, the needles of the larch are deformed , bending elbow-like. In summer, the shoots become profusely covered with a white waxy coating. Some of the heathers get wings and fly onto the spruce trees.
Combating the spruce-larch spruceconsists primarily in cutting and burning galls by hand. This must be done before the aphids hatch from them. Unfortunately, with a large number of plants or tall trees, manual removal of galls is almost impossible. Thenspruce-larch spruce spraying
Spruce-larch moth. Knee-shaped larch needles
During the dormant period, preferably in the early spring (March),spraying the spruce-larch oil agent with the oil preparationThe purpose of this spraying is to destroy the forms hibernating on the shoots of conifers. We can use Promanal 60 EC (based on paraffin oil) or Emulpar 940 EC (based on pine oil). Both are similarly effective, natural, with negligible harm to the environment.
If spraying in the early spring is not enough andwe notice the symptoms of feeding in spring , in April or May, spray with a pyrethroid agent, eg Karate Gold. If there is white fluff covering the needles in summer, a systemic aphidicide should be selected. Preparations worth recommending are Polysect 005 SL and Mospilan 20 SP.They both contain the same active ingredient, so it doesn't matter which one you choose.
If you also want to stay withnatural methods of combating elbows in summer , use Agrocover Target preparation for spraying, which sticks to the bodies of aphids and causes them to suffocate.
