Pegawai Google Bing Yandex Bericht - Rußtau-Krankheit in Kaffeeanlagen (Root Down) - Soot dewdrop is one of the most common diseases found in coffee cultivation. In addition to coffee plants, this disease caused by Root-down fungus can also attack several other plantation crops such as rubber, cacao, and cloves. In coffee plants and cloves, soot dew attacks the leaves, while in sooty moisture rubber plants often infect stems.
In general, root-down fungi attack plants that are surrounded by lots of dompolan or green lice. The feces from these fleas contain a lot of glucose and eventually become food for Root-down fungal growth. Root-down fungal colonies found in the upper leaves grow to cover the leaf surface and interfere with photosynthesis in plants.
Symptoms of Sores
Symptoms of soot dewdrops on coffee plants are very easily recognized because their attacks can be identified directly through the appearance of the plant. The following are some of the symptoms:
- On the leaf surface there is a black layer which is a root-down mushroom colony.
- The leaves are usually there are many black ants that gather to take part in eating glucose from the feces of dompolan and green lice.
- The black layer makes the temperature on the leaf surface even higher during the day because black is a color that absorbs heat.
- Because of the high leaf temperature in the dry season the leaves quickly wither and fall.
Unlike complex control techniques for controlling black root fungus and brown root mushrooms, sooty dew disease control techniques are generally carried out in a fairly easy way. Control can be done by reducing the population of aphids and lice dompolan through the application of insecticides. The application of insecticides is also carried out in order to reduce the black ant's popolation. The population of black ants also needs to be reduced to minimize the number of root-down fungus spores that spread through the intermediaries of ant legs.
To normalize the function of the leaves infected with fungus root-down, use warm water and a cloth to clean the sooty leaves. This method is indeed a bit tiring, but it will be very effective if done carefully. Removing the black layer on the leaves can also be done with the application of fungicides made from Mankozeb.
Thus the discussion of the symptoms of the sooty dew disease attack on coffee plants along with some of the control techniques. Hopefully it can be useful and for information about several other pests and diseases of coffee plants
