The following are ways of getting rid of aphid pests and diseases. The methods below are aggregated into categories and explained based on their categorizations.
1. Manual elimination by hand removal
2. Biological removal
3. Ridding by chemical application
Each of these categories and their methods of application to pests and diseases of rose plants is unique and effective in different ratios.
1. Manual elimination by Hand Removal
This is a straightforward technique that you can easily apply to get rid of aphids on roses. It involves the use of a scraper or a damaged credit card, to scrape through the leaves with aphid infestations making them fall off and die.
Aphids are slow movers and so cannot climb back through the stem onto the leaves of the plant.
You could also use the technique of water splashing or slow misting to dislodge the aphids and their eggs from the leaves. This method involves spraying the affected leaves, especially their underparts, with water to dislodge aphids and their cocoons.
The act of spraying to remove aphids is beneficial in the sense that it also helps to water the rose plant. Meanwhile, care should be taken not to overwater a plant as this will lead to a decline of the plant health caused by root rot.
The last manual technique is pruning. Pruning the plant is a way of getting rid of aphids from the plant leaves at their early stages of infestation.
Aphids are slow movers and so cannot fly off or crawl to other plants or parts of the plant.
2. Biological Removal
This method involves the introduction of biologically active insects that serve as predators of pests and diseases.
A characteristic of this method is the fact that the introduced species are not planted feeders and so cannot feed on the plant leaves. They only exist to rid the plants of pests and diseases.
Some natural predators of aphids are lacewings, mealy bugs, big-eyed bugs, soldier beetles, and ladybugs. You can either attract these biological aphid pest predators to the plant or you can introduce them.
Attracting them to the plant involves setting the right conditions in place for these predators to thrive. For example, you can plant blue tansy flowers alongside your rose plant to attract hoverflies.
Hoverflies predate on a lot of different pests and diseases, aphids inclusive.

ii. Liquid soap
iii. Neem oil

To apply vinegar to the rose plant, mix a spoon of vinegar to sufficient water then sprinkle on the affected leaves and every point where aphid spots have developed.
Ensure the solution is diluted well enough with water as acetic acid can also harm plants.
ii. Liquid Soap
There should be no difference in the liquid soap used for the removal of aphids from roses and the one used in washing dishes at home.
Liquid soap is made of a fatty acid and potassium concentrate that harms and stops the respiratory processes in aphids, which eventually leads to their death.

Neem oil is an extract of the neem tree that has over the years served as a multipurpose pests and diseases remover.
Neem oil irritates aphids and makes them fall off or die on the leaves.
Neem oil should be mixed in water and sprinkled on the leaves thoroughly.
Permethrin is a commercially distributed insecticide that is safe for application on domestically edible plants for the removal of aphids.
It contains the chemical compound pyrethroid that affects the neural functioning of aphids.
