SBI Plant Invigorator - a well-kept secret
We came across this product when looking for a spray that would control citrus mealy bug when light levels were low in the winter. We now use it extensively on imported pot plants, which often arrive with a few aphids or other unwelcome guests. This is another product from natural ingredients which is totally biodegradable. It has a three-way benefits. It controls mildew and other fungal infections. It acts as a foliar feed to strengthen plant growth. It attacks a wide variety of insects on contact, simply by gumming up their wings and breathing tubes.
The 500ml bottle goes a long way - it will dilute 100 to 1 to make up 50 litres
We use SBI to control and reduce aphids, blackfly, red spider mite, scale insects
and mealybug at our nursery at Fletching Glasshouses. We use it almost every other
week and wet the plant thoroughly including the undersides of leaves where the aphids
and crawlers like to lurk. Repeat applications are necessary because it works by
"suffocating" the smaller insects and there will always be the danger of more hatching
out or flying in to replace them.
