No effective herb has yet been grown against fruit fly maggots. If you want to have maggot-free fruit, in some cases the only solution is to use a spray that is not harmless to the environment.
Which spray can you use for cherry trees?
A suitable spray for cherry trees is Dr. Stahler Mospilan SG. It fights fruit flies and their maggots, which make cherries inedible. However, spraying should be done responsibly to avoid damage to the environment and he alth.
If possible, prevent
One of the most important pests of the cherry tree is the fruit fly, whose maggots make the cherries inedible. Since the annoying insect swarms between the end of May and the beginning of July, depending on the temperature, the first preventive measure is to plant the early varieties whose fruit formation has already been completed by the time of flight.
Wrapping the cherry tree completely with a close-meshed net has proven to be an effective preventive measure. However, this measure is only applicable to relatively small trees. For the home garden, we recommend the so-called “yellow boards”, which hang in the tree and attract the flies that stick to them.
When splashing cannot be avoided
If prevention is not possible, e.g. B. with an old cherry tree, the gardener has no choice but to treat the fruit with a suitable spray if you don't want to miss out on the harvest. For this purpose, appropriate sprays are available for use in a home garden.
The sprays are not ecologically harmless, as their use also attacks the beneficial insects and damages adjacent plantings and, last but not least, can have an impact on people's he alth. The decision as to whether or not to resort to the “chemical club” should be made by every gardener on their own responsibility, taking into account that the spraying is only effective if it applies to all crops.
The spraying is carried out at the beginning of the fruit fly's flight period. Under no circumstances should you spray during flowering. Spraying is best carried out when the sky is overcast and the wind is calm. It is beneficial if the surface of the plant is moist from dew or rain because then the broth is distributed better. It makes sense to use a standard spray pump and protective clothing.
