In previous articles I discussed about Roses Caring Guide with Full Management Practices and also about rose diseases, but I did not talked 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 on the plant. It is not necessary to tell what happened when they attack to 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 on damages. Let’s see who the rose pests are.

Aphids

Aphids

Aphids are most common very destructive type of insect. They can be seen in black, orange, red or green color. They are mostly damage 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 sever conditions slower growth, malformed flowers or late opening of flowers like symptoms are resulted.

Contactable insecticides like Penitrothin, Primaforce methil also effective.

Mealy Bug

Live on plant stems and under side of the plant leaves. Depend on plant sap by sucking them. Mealy bugs can be seen in naked eye. They are coated by whitish powder. It is help to identify them easily.

Lower amount are not that much problem but in sever conditions weak plants are resulted. Photosynthesis surface is reduced. They are covered plant and seems like plant is white.
To control them spray a soap solution. In sever conditions spray insecticide like Dimethoate. 

Scales

Scales are small circular or oval shape 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 look at them seems as 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 is 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. On 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, fat worm that can be seen under the soil. They are damage to the rose roots by eating 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 ploughing or add chlorpyrifos included pesticide to the soil.

Leather Jacket

Leather Jacket is a Black or brown color worm that live 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 is consisted 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 top and bottom epidermis. It is seem 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 are seemed as brown in color. Use below pesticides to control them.

Ex: - Dimethoate, Monocrotophos

Caterpillar

Rose pest control- caterpillar damage

It is a part of moth’s life cycle. There are several species that depend on rose leaves. Anyway they damage to the leaves by making irregular holes on leaves. It is 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 form the leaves. It is seems as yellow color dye on the leaves after the damage. Mostly yellow color patches can be seen. If the insect live, exoskeletons can be seen under side of the leaves in white color.

Weak plants, slow growth rate and defoliation before mature the plant are resulted 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 under side of the leaves. Light yellow brown color insect. Most probably cobwebs like fibers can be seen under side of the leaves. When the insect suck the sap, it is become copper color on the leaves. It is more sever 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 is consisted with shiny green and brown color exoskeleton. It is damage on rose petals. It is eat 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 eat rose petals. Mostly they can be seen in the evening in between the petals. Beetle is mostly damage on white and yellow color flowers. Need to use a systemic pesticide to control them.

Thrips

Thirips are mostly damage on the flowers. They are specially damage on petal edges. They suck the sap from edges. Therefore petal edges are become to brown and flowers are malformed. Thrips have small four wings and in dry seasons damage is high. 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 first stages remove the damage parts to control the pest. Systemic pesticide is better to control.

Capsid Bug

It is damage on leaf and flower buds. Sap sucking insect. Brown patches on the leaves, flower buds and leaf buds are died after the damage. 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 is help to keep a healthy rose plant.
