Monterey Brush & Vine Control is not labeled to control or kill azaleas however per the product label, this product should not be around vegetable crops, flowers, ornamentals, or other desirable foliage.
For best results, apply as a full coverage foliar spray when brush and weeds are fully leafed out and actively growing. Wilting or other symptoms will occur in 1 to 6 weeks. Apply only when the air is calm to prevent drift to desirable vegetation.
