When it comes to growing roses, it's impossible not to mention their pests and diseases. Previous articles have introduced a prevention plan for rose pests and diseases, but in a reader's group yesterday, a gardening friend asked about a question related to insects.
So I've decided to talk about this little insect again today.
Many people may not recognize this insect, but mentioning its name should be familiar to most gardening friends. It's the flower thrips.
The adult flower thrips is a small black insect with wings and moves very quickly, often making it difficult to see its true form.
This light yellow or off-white little insect is only one or two millimeters long, moves very slowly, and often hides in curled new leaves, sucking sap. This is the nymph of the flower thrips, simply put, the baby of the flower thrips.
It is now the time for flower thrips to breed, and also the best time for us to prevent them. If you find that the new leaves of your roses are curled, with black spots or withered tips, you might want to take a close look at the back of the leaves, where you will often find these little insects.
The adult flower thrips is very secretive in its movements and not easily detected, making the effect of chemical control less than ideal. However, if we can eliminate the flower thrips in the nymph stage, we can greatly reduce the occurrence and harm caused by them.
Prevention methods:
For the nymphs of flower thrips, the method of poisoning is very simple. You just need to spray with wettable powder of dinotefuran. When spraying, make sure to spray both sides of the leaves.
If you also grow roses, to prevent flower thrips from damaging your roses in the summer, start preventing them now and eliminate the flower thrips in the nymph stage. For more home gardening tips, please follow the public account: Garden (ilanyao)
