I have tested the Neem Oil against aphids with good results but we must be patient as there is not always a sufficient treatment.
So here are I to Neem Oil.
Mix 1 – 2 TSP. in 2 litres of tap water + 1/2 TSP. SOAP. Mix everything well.
Pour into a Spray bottle and spray the solution into the ground and around the stem and all the leaves and branches, be extra careful to spray the leaves in the pages. Repeat this treatment 3 days in a row and wait 2 – 3 days and then check through the plant carefully. Would aphids remain so repeat the treatment again.
A little info about what Neem Oil is and how it works.
Neem Oil obtained by crushing the seed from the fruits from the tree Neem (Azadirachta indica) The oil produced is non-toxic. The active ingredient of Neem Oil is azadiractin and it affects insects in a different way.
- It prevents the adult insects from developing a hard skeleton, causing dehydration.
- It prevents the egg production and sterilize insects, making it impossible for them to reproduce. Neem Oil interferes with digestion and also insects excretion secretions.
Neem Oil affects interesting enough not to beneficial insects.
