Horticultural Soft Soap

Horticultural Soft soap is a highly refined soap made from natural oils which acts as a contact insecticide with no residual effects once it has dried.

It comes as a concentrate and if used at dilution of 30-50 x it will reduce the population and the breeding capabilities of  pests such as Aphids, Whiteflies, Red Spider Mites, Thrips, Mealybug and Scale insects .  Soft soap works by plugging up the breathing holes in the insects body, and also by sticking their wings and moving parts together.

We started using it ourselves when we had an attack of scale insects on peppers and citrus in our nursery. The great thing about it is that it is not a poison and can therefore be used quite safely on edible crops – something that is quite important to us as we use a large section of our nursery for growing edible leaf crops such as salads and spinach and chard.

It can be applied simply to individual leaves and stems with a sponge or it can be sprayed using a suitable dilution – up to 50 times. It’s not advisable to use it too strong as it can damage the plant also. Indeed some plants notably Fuschias. Ferns and some bedding plants don’t respond well at all.

However as a simple, easy to use, inexpensive remedy for a number of pests it’s hard to beat.
