Ready to use 3 in 1 defender technology to control bugs, powdery mildew and provide roses with nutrition. Ecofective Rose Defender works by physical mode of action to encapsulate the bugs making them immobile which stops them from feeding. It controls a wide range of pest species including whitefly, aphid, red spider mite, mealybug, scale, and psyllid and also helps to control, with regular use, powdery mildew by physically washing the foliage to remove active mildew spores. The formula also provides foliar nourishment to encourage vibrant, healthy roses. Now available as a concentrated refill to help reduce waste. Simply pour the 200ml refill into your empty 1L spray bottle, add water and start controlling the pests in your garden again.
