Trees Like most forms of plant life, evergreen trees require periodic pest and disease control to remain healthy. There are a variety of insects that could potentially infect your trees. Black scale, for example, is a destructive parasite that sucks the nutrients from plants, causing them to quickly wilt and die. To ensure that you keep your trees alive and thriving, it is important to properly identify any insect infestation or other illness in order to get it treated as soon as possible.
Insecticide For Evergreen Trees
The first step in pest control is choosing disease-resistant plants. Here are some tactics for when infection strikes, from killing aphids to stopping common fungus.
1. Aphids, white flies and spider mites
- Aphids, mealy-bugs, leaf hoppers, cottony scale and white flies love to eat leaves and needles.
- Infested needles and shoot tips become sticky or deformed when plagued with these bugs, and may show sooty mould. Pests could also be visible.
- Spray with insecticidal soap to kill them. Use soapy water to remove sooty mould.
- Foliage with spider mites turns yellow, then brown. It may have a purplish tinge.
- To get rid of little mites, spray forcefully with water, especially undersides. Also apply insecticidal soap every 5 days.
2. Borers and caterpillars
- Shoots of trees with borers will wilt, become crooked or stunted. They then die rather quickly.
- To destroy borers, prune out the infected shoots and destroy.
- Caterpillars, sawfly larvae, gall midges all leave eaten needles, entirely or in part.
- Apply Bacillus thuringiensis for caterpillars, insecticidal soap or neem for other pests.
3. Canker fungus
- Cytospora canker fungus causes needles to turn yellow and fall. White resin may appear on the on trunk and branches.
- Prune the infected branches. In spring, spray 3 times, every 10 days, with copper-based fungicide.
4. Needle cat fungus
- Needles with this fungus turn yellow in late summer, brown in winter, and eventually drop. It often starts at base and moves up.
- Needle cast is common in spruce and pines.
- To help your tree fend it off, spray with a Bordeaux mixture. Spray in summer, 3 times, every 21 days.
5. Rust fungus
- Several different rusts attack conifers.
- Infected trees will have dead branches in the crown, white resin on the trunk or yellow patches on its needles.
- To cure, prune out infected branches and spray with wettable sulphur.
6. Twig blight fungus
- The telltale sign of this fungus us that shoot tips yellow in fall. Needles will also hang on without falling and black spots can appear on shoots.
- Prune infected shoots, and spray 3 times with copper fungicide after the needles fall.
If buying a disease-resistant tree doesn’t work, you can try these solutions. They’ll mostly be useful for young trees, but if a tree suffers problems year after year, it’s better to cut it down and replace it with a different species.
