A rose is a woody flowering plant from the Rosa genus of the rosacea family in the plantea kingdom.Roses are plants that naturally gives offsprings through insect-pollination.
There are more than 300 species of roses around the globe and each single rose specie is different from another specie in many characters.
Roses are useful in many ways, for instance some of them bred naturally to give some of the beautiful flowers that a human eye can see.
While others have the most attractive aroma in which the are used as the key ingredient in many top perfumes and deodorants.
But like any other plant in this world roses can become infected by pests which might heavily reduces its yield.
That why I wrote you this article, to show you the different kinds of pests that might harm a rose plant and their solutions.
- Insecticides for roses
- Fungicides for roses
- Herbicides for roses
- Plant growth regulators for roses
Insecticide for roses
Many species of insects can attack a rose plant which may vary greatly on their treatments. Most of these insects attack the plant to get some benefits from its leaves.
In order to protect your plant form such pests you need first to go through a process called scouting in which it is a process to inspect your plant for any damage done by insects.
Damages such as discoloration of the leaves, unusual growth and swellings maybe caused by pest insects.
If such insects are discovered on the plant’s surface you must consider the best pest management system.
Below I have jotted down the most common kind of insects that may attack a rose plant with its best solution to totally eliminate it.
Sawflies are small sized, dark wasps with more than five pair of prolegs in which most of the time they are unable to sting.
The larvae of this insect attack and feed on the leaves of the rose plant, by other words it is a insect pest that feeds on the plant’s leaves.
There are total three species of these kind of wasps in which the three of them are orange headed and can reach up to 19 mms in height.
You can scout these kind of pest insects on the plant surface by searching for any chewed leaf layer that its veins has not been touched.
This process Is called skeletonization in which the larvae only eats the leaf layer leaving the leaf veins which result in a skeleton like structure.
The best solution you can use to control these pest insects is by simply picking them up by hand in which they are large enough to picked out by hand
But dozen other treatments are available whether they are physical or chemical, for instance some low-toxic biopestcides such as neem oil (azadriactin) and bacilus thuringlen can also be a very good treatments.
Aphids are small, green insects which most of the time they are not easily noticed. They feed and bred on the tips of the rose buds.
These insects are extremely small in size in which an average aphid can only grow to be three mms in length.
They mostly attack the plant in groups in which most of the time they feed by sucking the plant’s juices which eventually result in distorting of the leaves of the plant and inability to grow.
You can scout the aphids by looking for any shiny, honey like sticky product that most of the times these insects produce in which in most cases ants are heavily constrained in that area.
The best solution in many cases is by physically dislodging them through a heavy stream of water but beside that other endless treatments are available.
3, Rose midges
A rose midge is a very small fly that lays its eggs in the buds and shoots of the rose plant.
And Soon after the eggs hashes a legless larvae appears which have a shiny whitish color and they can reach up to 1 mm long.
You can easily scout them since after the plant has been infected by these kind of pest insects the plant’s shoots turn into Brown color and eventually into a dark black color.
You can also use a magnifying lens to look out for any whitish, legless fly larvae around the plant’s shoots and buds.
If the insect is only present on just the buds and shoots of the plant there is no need to apply any pesticides, you can get rid of it by simply cutting down the infected parts of the plant.
But if the plant is severely infected by insect you must go for the chemical pesticides in which systematic insecticides are effective if the infection went out of control.
Acephate and cygon-2E are one of the best systematic insecticides on the market that I recommend using if such scenario occurred.
4, Gall wasps
Gall wasps are tiny, cynipid wasps that are unable to sting wasps that most of the time live and feed on a plant by producing galls that wasp larvae develop inside it.
You can scout them by searching for any mossy, rose galls that occur on the plant steams in which most of the time they are have spherical structure.
As with the rose midges the treatment you can use to get rid of these insects is by cutting down the infected areas of the plant before the larvae mature to be adult wasps.
Because as soon as these larvae turn into wasps they will start producing other galls on the same plant and vice versa and eventually this will produce a huge pressure to the plant which result in slow growth rate.
Fungicide for Roses
Most of the diseases that attack roses are caused by fungi with the black spot fungus (diplocarpon rosae wolf) being the most common rose disease in the world.
A fungus Attack can be the major cause for the emerging of many symptoms that affect the plant.
And In Most cases if a plant is infected with a fungus it will probably be the black spot fungus
A rose black spot is a fungus generated disease that is caused by the fungus diplocarpon rosae.which Is an infection that causes a big circle dark spots in the leafs of the roses.
The primarily symptom in a black spot fungus infection is the development of dark spots which can reach up to 30 mms in height.
There are plenty of options regarding fungus protection methods but I deeply recommend cultural fungus disease managemen technique.
It is possible to completely avoid any kind of fungus infection that can potentially harm a rose plant by simply following a healthy day to day routine with plant.
The other kind of treatment you can use in tense situations is by using chemical fungicides in which a frequent application is required every 7-14 days on average for best results.
You can also easily make your own natural fungicide at home by following the set of instructions below.
Using sodium bicarbonate
Step one: collect the necessary materials
- One teaspoon of baking soda (sodium bicarbonate)
- One teaspoon of vegetable oil
- One gallon of water
- 1-2 gallon plastic bottle
Step two: combine
Mix well all of the baking soda, vegetable oil and the water inside the plastic bottle. After it has been successfully mixed you can start using it you must apply it on the roses every 7 to 10 days.
Herbicide for Roses
Because Weeds or herbs are pest plants that compete with desired plants for sunlight and food which eventually results in lower yields.
And because of the fact That roses mostly grow in the landscape,weeds can be a real big problem for them if weeds and they may weaken the plant servely and that is why a good solution is required.
Generally, there are two kind of weed management we can use to ensure a healthy growth of our roses.
Which are by using cultural practices and by using herbicides.
1, cultural practices
This the best weed management method in my point of view
this is due to the fact that in this method you are not required to use any harmful chemicals that may harm your roses or even have to spent any money on weed fighting chemicals
this resembles the most cost effective and best solution and all you have to do is plant all of your roses in one suitable area out of any external plants and Believe me not a single weed will ever get near to them.
2, using herbicides
Even so, cultural practices resemble a perfect solution at some point you will be forced to use any kind of herbicides.
If so, please try to use natural herbicides because some chemical herbicides contain very toxic ingredients and they might harm your roses severely.
Try to be very care full when choosing the right herbcide, although systematic herbicides like glaysphote are very good in weed management you can also use simazine and Atraizine.
Plant Growth Regulators for Roses
A plant growth regulator is a substance with numerous chemical ingredients that profoundly affects the growth hormones of a plant cell.
There are five basic hormones inside a plant cell that has a vital role in a plant’s growth regulation and They are Auxins, cytokines, gibberlins, abscisic acid, ethylene.
There are many commercially made products that can be used as plant growth regulators in which your roses can benefit of in which the most common ones are systematic but there are also contact.
Roses are the most favorable kind of plants for most people they are the symbol of love and mercy and people use them for many advantages.
And still the rose market is booming and from day-to-day more people are purchasing more of this plant and if you are one of these people who are responsible for these flowers to get to the market i am sure you have benefited from this article
And i am sure that pesticides won’t be a problem for you next time you are going to plant some new rose plants.
sorry to say that but it is the end of the article and till next time.
you can now please your partner with some fresh roses from the garden, cheers.
