When it comes to growing roses, we have to talk about rose pests and diseases. In previous articles, Lanyao also introduced a prevention plan for rose pests and diseases, but yesterday in Lanyao's reader group, a flower friend asked a question about an insect. So Lanyao decided to talk about this little insect again today.
Looking at this insect, many people probably do not recognize it, but if you say its name, most flower friends should have heard of it: it is the flower thrips. In previous articles, Lanyao introduced flower thrips. Flower friends who have read Lanyao's earlier articles on pests should still remember that the flower thrips Lanyao introduced before did not seem to look like this?
The adult flower thrips is a small black insect like this, with wings and very fast movement, so it is often difficult to see it in person.
This kind of small beige or off-white insect, only one or two millimeters long and very slow-moving, often hides in curled new leaves and sucks sap. This is the nymph of the flower thrips, in simple terms, the baby of the flower thrips.
Now is exactly the time when flower thrips reproduce, and also the best time for us to prevent flower thrips. If you find that the new leaves of your roses are curled, with black spots or scorched tips at the leaf tips, you might as well carefully observe the underside of the leaves, and you will often find this small insect.
Adult flower thrips are very secretive in their activity and not easy to find, and the effect of pesticide use is often not ideal, but if we can eliminate flower thrips at the nymph stage, then we can greatly reduce the occurrence and severity of flower thrips damage.
Prevention methods:For the nymphs of flower thrips, the poisoning method is very simple: just spray with acetamiprid wettable powder. When spraying, pay attention to spraying both the front and back of the leaves.
If you also grow roses, in order to prevent flower thrips from making your roses twisted and misshapen in summer, then hurry up and start preventing them, and eliminate flower thrips at the nymph stage. At present, some roses have been pruned and are relatively small; flower friends can enter the store to buy
