The Safer® Brand BioNEEM® Insecticide and Repellent concentrate works as a powerful insect killer and as a repellent. This product is formulated with azadirachtin, a natural Insect Growth Regulator extracted from the Neem seed. As an IGR, the neem oil in BioNEEM® disrupts insects delicate hormonal balance, killing them before they molt into their next life stage.
Use a neem oil solution such as BioNEEM® on trees, shrubs, ornamentals and flowers. Water to concentrate ratios vary per the type of plant being treated.
Safer® Brand BioNEEM® works very effectively by suffocating the insect. Remember, when using neem oil products, there is greater risk of phototoxicity (burning). Avoid using sulfur based fungicides within the active period (5-7 days) of the BioNEEM® application. These two products combined, greatly increase the risk of plant burn.
While Safer® Brand BioNEEM® is a contact killer, several applications of the neem oil may be needed for full control. As a general rule, much like watering, do not use neem oil in the peak of the day or when temperatures exceed 90 degrees F to avoid wilting or browning of the leaves.
Dang good stuff!
