Like all other plants in the garden, iaquatic plants can get sickand be attacked by pests. Unfortunately, the fight with these problems in the pond environment is particularly difficult, as it is practically impossible to control diseases and pests with chemicals. So how do you deal with them? Here are the most commondiseases of aquatic plantsand the best methods to combat them.
Diseases of aquatic plants - stains on the leaves of water lilies and their premature yellowing may be the result of plant infestation by a fungal disease or rotting of their rhizomes
How to prevent diseases and pests of aquatic plants?
Virtually all available chemical preparations for fighting plant diseases are poisonous to fish and beneficial insects. In the fight againstdiseases of aquatic plantswe are left with mechanical methods (removal of infected plant parts, collection and destruction of pests), biological (creating favorable conditions for the existence of beneficial insects in the garden, which are natural enemies of pests plants) or the possible use of biopreparations.
First of all, however, you should provide aquatic plants with good conditions for growth, because weakened plants will become ill more often and fall prey to pests. The plants for the pond, which grow in the coastal zone and with floating leaves, require the most optimal growing conditions.
In order for these natural methods of fighting diseases and pests of aquatic plants to be effective, it is necessary to regularly check the condition of the aquatic plants.When you notice symptoms of disease, remove diseased or dead leaves, and if necessary - even whole plants. Collect larvae and beetles from the surface of the leaves. Remember that your allies are songbirds that feed their young with larvae and beetles. So let the birds be in the vicinity of your water garden.
However, if the disease symptoms worsen significantly or the pests occur en masse, it may be necessary to apply more radical measures. However, first you need to identify the cause of the problem - only then will you be able to choose the appropriate actions. Below we present the most common problems in the cultivation of aquatic plants.
Diseases of aquatic plants - descriptions, combating
Symptoms:yellowing leaves in the growth phase
Reason:iron deficiency
Combating:Use a special fertilizer for aquatic plants with iron
Symptoms:white, mealy mycelium coating on plant leaves and shoots,
Cause:powdery mildew, a fungal disease, mainly affects weakened coastal plants at the end of the growing season,
Control:In order to prevent the spread of the disease, remove the infected parts of plants, provide the plants with the best environmental conditions, possibly apply a biopreparation Biosept Active
Symptoms:tiny, reddish spots with concentric rings, with time they enlarge and merge with each other to form black, irregular, rot surfaces, with time stains form in place of the spots hole,
Cause:fungal leaf spot disease, a fungal disease, the development of this disease is favored by warm, humid weather, lasting for a long time, therefore the disease appears most often at the end of summer,
Control:remove infected leaves, apply biopreparation spray Biosept Active (at a concentration of 0.05 to 0.1%), repeat spraying after 7 to 10 days,
Symptoms:water lily leaves turn yellow and die, after looking at the rhizomes of plants you can notice that they rot, blacken and give off an unpleasant smell,
Cause:rhizome rot, the disease affects mycelium, occurs when plants are grown in too cool a position, have too little sun or when the wrong substrate has been used,
Control:in case of slight infestation, plants can be treated, for this purpose the plants must be removed from the pond and placed in a large container with a solution of Magnicur Energy or Biosept Active, after about 3 to 4 hours, replace solution for clean water and leave the plants for a few weeks until they fully regenerate, unfortunately, when the infestation is too high, the diseased plants must be removed.
