In previous articles, I discussed Roses Caring Guide with Full Management Practices and also about rose diseases, but I did not talk much more about rose pest and their control practices. So in this guide, I am going to describe the most common rose pest and controlling practices for them.

As the diseases, pest also damages the plant. It is not necessary to tell what happened when they attack the plant. Every pest does damage on the plant like diseases do it. Most of them don’t know how to identify pest and diseases and also whether the damages from a disease or pest. After reading this you will get a good knowledge to identify them and treat damages. Let’s see who the rose pests are.

Aphids

Aphids

Aphids are the most common very destructive type of insect. They can be seen in black, orange, red or green color. They are most damaging on apical and flower buds by sucking them. To control aphid, it is better to use a systemic insecticide to control them.

Ex: - Carbofuran, Dimethoate, carbosulfan, Imidacloprid, Formothion, Fipronil  

In severe conditions slower growth, malformed flowers or late opening of flowers like symptoms result.

Contactable insecticides like Penitrothin, Primaforce methyl also effective.

Mealy Bug

Live on plant stems and underside of the plant leaves. Depend on plant sap by sucking them. Mealybugs can be seen in the naked eye. They are coated by whitish powder. It helps to identify them easily.

The lower amount is not that much problem but in severe conditions, weak plants result. Photosynthesis surface is reduced. They are covered plant and seems like the plant is white.
To control them spray a soap solution. In severe conditions spray insecticide like Dimethoate. 

Scales

Scales are small circular or oval-shaped insects. They are covered with an external scab. Mostly live on old rose stems and roots. They use those plant parts to suck the plant sap. When looking at them seems like a part of the stem because they are completely attached to the stem. To control them need to spray Dimethoate like systemic insecticide. When use contactable insecticides, need to spray to fully get wet them.

Shoot borer   

Shoot borer damages to the soft stems or apical buds. Making holes they are entered stem and destroy the medulla. Apical buds are wilting when they attacked. So it helps to identify this pest.

To control this need to cut off damaged parts and add a systemic insecticide.

Ex- Carbofuran, Dimethoate, carbosulfan, Imidacloprid, Formothion, Fipronil

Ants and termites

Some ants and termites depend on eating rose roots. For this reason, most rose plants are wilting or die. To control the damages from these insects, it is important to add organochlorine or Organothiophosphate pesticides. Need to apply them to the soil around the plants.  


 Ex: - Diazinon, Imidacloprid, Chlorpyrifos  

Chafer grub

Chafer grub is a white color, a fat worm that can be seen under the soil. They are damage to the rose roots by eating the bark of the roots. So immediately a plant is wilting and then dies. Chafer grub does a huge damage on rose plants. So need to collect them and destroy when plowing or add chlorpyrifos included pesticide to the soil.

Leather Jacket

Leather Jacket is a Black or brown color worm that lives in soil. It is not bigger than one inch. Mostly damage to the roots and stem near to the soil. Manually collect and destroy them when soil preparation or add a recommended pesticide to kill them.

Ex: - Chlorpyrifos

Cockchafer Beetle

It consists with black color shiny head and red-brown color protective feathers. Normally it is about 10x8 cm larger insects. It is eating leaves making irregular holes. In additionally in the evening they eat rose petals. This rose pest control can be done by using a proper pesticide.

Ex: - Penitrothin, Dimethoate

Leaf Miner

They eat the cells in leaves in between the top and bottom epidermis. It seems like paths on the leaves. Remove the damaged leaves or put a systemic pesticide to control them.

Ex: - Carbofuran, Dimethoate, carbosulfan, Imidacloprid, Formothion, Fipronil  

Rose Slugworm

It is a small worm. They are Green or yellow in color. They can be seen on the leaves. They eat rose leaves only remaining veins. Destroyed parts seem as brown in color. Use below pesticides to control them.

Ex: - Dimethoate, Monocrotophos

Caterpillar

rose plant caterpillar damage

It is a part of moth’s life cycle. There are several species that depend on rose leaves. Anyway, they damage the leaves by making irregular holes on leaves. It helps to recognize this pest. Use below pesticides to control them.

Ex: - Dimethoate, Monocrotophos

Leaf Hopper

Rose pest control- Leaf Hopper Damage

It is a small yellow color insect. It is sucking the sap from the leaves. It seems like a yellow color dye on the leaves after the damage. Mostly yellow color patches can be seen. If the insect lives, exoskeletons can be seen the underside of the leaves in white color.

Weak plants, slow growth rate, and defoliation before mature the plant result when attached the pest. Use a suitable pesticide to control them.

Ex: - Carbofuran, Dimethoate, carbosulfan, Imidacloprid, Formothion, Fipronil  

Red Spider Mite

Rose pest control- Spider Mite Damage

It is very small incest that sucks the sap underside of the leaves. Light yellow brown color insect. Most probably cobwebs like fibers can be seen on the underside of the leaves. When the insect sucks the sap, it becomes copper color on the leaves. It is more severe in warm conditions. Need to use a systemic pesticide to control them.


Ex: - Carbofuran, Dimethoate, carbosulfan, Imidacloprid, Formothion, Fipronil  

Rose Chafer Beetle

It is not bigger than 1 cm. the insect consists of shiny green and brown color exoskeleton. It is damage on rose petals. It is eating rose petals. Use a systemic pesticide to control them.

Garden Chafer Beetle

It is somewhat smaller than Rose Chafer Beetle. It has a small black color head and shiny brown color exoskeleton. It is also eating rose petals. Mostly they can be seen in the evening in between the petals. The beetle is most damaging on white and yellow color flowers. Need to use a systemic pesticide to control them.

Thrips

Thrips mostly damage the flowers. They are especially damaging on petal edges. They suck the sap from edges. Therefore petal edges become too brown and flowers are malformed. Thrips have small four wings and in dry seasons damage is high. A systemic pesticide is better to use control them.

Ex: - Carbofuran, Imidacloprid Dimethoate carbosulfan, Formothion, Fipronil  

Tortrix Moth

The warm is piercing the flower bud and live in there. If not make a leaf as a role and live inside of it. In the first stages remove the damaged parts to control the pest. A systemic pesticide is better to control.

Capsid Bug

It is damage to leaf and flower buds. Sap-sucking insect. Brown patches on the leaves, flower buds, and leaf buds die after the damage. A systemic pesticide is better to control.

Ex: - Carbofuran, Imidacloprid Dimethoate carbosulfan, Formothion, Fipronil  

Rose pest control is not that much difficult, but need to keep the continuous attention on them. It helps to keep a healthy rose plant.
