Your beautiful roses bring you so much joy with your lively colors, lush flowers and long flower time. But if you recognize something that crouches you, it's a little annoying. “Many different types of insects and mites can influence roses,” says Rafia Khan, PhD, assistant professor and expansion tomologist at Texas A & M Agrilife Research and Extension Center. “By regularly checking your plants, you can catch infestation at an early stage if it is easier to manage pests.”
If you pay attention to the type of damage, you can identify the pest so that you can handle it appropriately. In general, rose pests fall into two main categories. Suck pestsLike aphids, penetrating mouth parts that are placed in plants and remove the juice, which turns the plantlide and the petals, curved or incorrect. They also sell honeydew, a sticky substance that can lead to building soil of soot, a kind of fungus that can affect the ability of a plant for photosynthesis, says Khan.
The second category are Chew pestsLike beetles that have mouth parts that chew on the leaf or flower, so that part of the plant or flower is missing, says Khan.
Planting blooming, pollinating -friendly plants promotes the presence of useful predators such as ladybugs, lime flies and parasitic wasps to manage these pests. In addition, most healthy plants can stop damage. However, if you have a large infestation or the plant fails noticeably, you may need to take measures, says Khan.
Here are the most common rose pests and what you can do against them:
Aphid
Leaves are tiny (1-2 mm), pear-shaped insects with soft, light yellow, green or pink; They suck the juice from plants. “You can find new growth in clusters,” says Wes Harvell, Rosarian at Jackson & Perkins. “Signs of damage includes distorted or hugged leaves and buds as well as sticky honeydew that promote sooty mold and attract ants.”
What to do:
Break them with a strong water current from the garden hose. You have to repeat this treatment every few days to reduce the population, says Khan.
Insecticidal soap or neem oil may be necessary if you cannot keep you at bay. Make direct contact because these products suffocate you, says Harvell. However, be reasonable with regard to the application and follow the label instructions, since these products also kill beneficial errors.
Mites
Spider mites are tiny arachnids that are typically invisible to the mere eye. They also suck pests that extract liquid and fabrics from the plants. Look for a fine belt band and spuried or suitable leaves that are signs of your presence, says Harvell.
What to do:
Hose spider mites of all deciduous surfaces, including between the leaves and branches. Repeat the process every week to 10 days to deal with newly beaten mites. Pay special attention to the belt band that protects it, says Khan.
These pests quickly become resistant to some insecticides, so that they experience an even more serious infestation, says Khan. For this reason, limit the use of pesticides for extreme situations or high -quality plants. If necessary, use insecticides soap, neem or gardening oils, follow the instructions of the label.
Sawbly
Also referred to as rose slugs, saw blades are stitchless, wasp-like insects. The light green caterpillar -like larvae are the damage to rose leaves. “Saws let small holes completely chew through the leaves,” says Stephanie Waltz, coordinator for rose sample with star roses and plants. “Or, in the so -called damage” window panes “, chew a part through the leaf and leave a thin, translucent layer.”
What to do:
In general, saws do not cause enough damage to disturb your roses in the long term. The encouragement of birds and useful insects in your garden will keep this pest under control, says Waltz. If you do not like the unsightly leaves or have a larger infestation that defines your roses, you can pick larvae from the leaves by hand.
Insecticidal soap, neem oil or spinosad are further options for serious infestation, but follow the instructions of the label. Or consider using a systemic insecticide that is characterized for use at Rose Sawfly, says Waltz.
Thrips
Thrips are tiny (less than 1 mm) pests with slim bodies that are yellow, brown or patterned. “They are hardly visible with magnification,” says Harvell. Silbry or spotty spots on leaves, brown or distorted petals, dark spots (feces) or flower buds that are not open are signs of thrips.
What to do:
“Early detection is the key, although control can be a challenge,” says Harvell. If you are not sure if you have thrips, keep a white piece of paper under flowers and leaves and tap to twist you to confirm your presence. You can remove or discard those affected.
Extreme infestation can possibly be used in insecticides or conventional insecticides, but remember that they also have good mistakes. Follow the designation instructions; You may have to treat again, says Khan.
Japanese beetle
Japanese beetles have metallic green bodies with copper wings. You will see chewed leaves and flowers as well as the beetles that gather and feed in groups, says Khan.
What to do:
Mluns and drop it into soap water; This method of the old school is surprisingly effective, says Khan. Do this in the morning when the beetles are less active.
Avoid using Pheromon traps or bags, research only put on research, says Harvell.
