Every season has its own pests that eat flowers, vegetables or fruit. Those who know these pests can react accordingly.The miner moth strikes against chestnuts
If you have a garden, you don't always enjoy it. A garden can sometimes give you gray hair. For example, when diseases and pests affect fruit, vegetables, trees, shrubs and flowers. After all, hobby gardeners don't know all pests and diseases. Then they experiment and try out. According to the motto “Either it works or not”. But you shouldn't take this risk. Every season, even every month, has its pests and diseases that occur during this period. In September it is e.g. Miniature moths, pear grate, asparagus chicken and gooseberry wasps.
We would like to explain in more detail how these pests and diseases are noticeable and how you can combat them.
Diseases and pests in September
Ier Mini moth:
Chestnuts have beautiful white to pink flowers and wonderfully large leaves. If they change color in autumn, it is a true natural spectacle. However, if they change color much too early or if they look eaten, then the leaf miner is often to blame. She lays her eggs on the leaves. When the larvae hatch, they feed on the leaves, which then become susceptible to disease and fall off.
Since the leaf miner likes to hibernate in the fallen leaves of the chestnut tree, you should collect the leaves regularly and dispose of them (not via the compost!). This will reduce the likelihood of an infestation again next year. This is the only way to master the leaf miner, because there are no approved plant protection products against this pest.
❍ Pear grid:
Pear grating occurs on pear trees from April and manifests itself in orange spots on the leaves. The spots change from July. Black warts then appear on the underside of the leaf. In itself, this is not a bad disease, because the pear grate does not affect the fruit. The pears are therefore suitable for consumption.
If you can still see pear grating on the leaves of your pear tree, then that's not a problem. You can compost these leaves or leave them there, because a new infection only takes place in spring.
❍ Asparagus Chicken:
If you have asparagus in the garden, you should now take a close look at the shoots. If there are green larvae with a dark head on them, then these are the larvae of the asparagus chicken. Collect them because they must not get into the earth. There they hibernate and eat away the young plants in spring.
Alternatively, you can water the ground with tomato leaf stock in autumn and spring. Simply pour a little water over a few tomato leaves and let the whole thing steep for a few days.
❍ gooseberry wasp:
Finally, you should check gooseberry and currant bushes for the larvae of the gooseberry wasp. They are green and have black warts. Collect them so that wasps cannot form in spring. It also helps if you cover the crown of your gooseberry or currant bushes with an insect repellent fleece from the flowering period until mid-August.
Alternatively, you can also use the gooseberry wasp larvae with a nature-friendly agent such as Fight Spruzit Pest Free from Neudorff (available here for example).
