A great way of getting rid of soft bodied insects like aphids and black fly without harmful chemicals, also due to the hature of this spry if used carefully there is virtually no risk to bees and other useful polinators!
Origins of Insecticidal Soap
It is thought that soap has been around since the days of the ancient Egyptians, and there are records of it being produced from tallow and beech ashes by the Phoenicians in 600 BC. It even gets a mention in the Bible: Jeremiah 2:v22.
Soft soaps have been used to control insects for more than 200 years, but recently there has been increased grower interest in using them again. There is a genuine desire at least to try substances that are safer to use than the array of chemicals on offer.
Benefits of the Insecticidal Soap
- Soft soap can kill insects, provided enough soap covers enough of the insect.
- It may also be useful against plant fungal diseases (at reduced rates).
- It can be used in a way to minimise effects on beneficial insects.
- Risk of spray scorch is much reduced in the absence of alcohol and detergents.
- It is regarded as environmentally safe, and is fully biodegradable.
- It is not persistent – an environmental and consumer benefit.
- Can be a useful water softener (and hand cleaner).
- Crop residues do not appear to be an issue.
