Azaleas are landscape crops that are stunning, lending an informal notice that is gracefully from what could be an otherwise simple garden. Gardeners love them for easy care, natural designs and their flowers. Azaleas can experience from leaf distortion unexpected wilt as well as leaf blackening as a result of sooty mildew. These signs are usually triggered by the mealy bug or its cousin, azalea bark scale. The plant can resume its peaceful life-style once these pests are eliminated.
Mealybugs
Mealybugs are typical on azaleas. These soft-bodied sucking insects may be viewed on the undersides of leaves and inside the portion of the development till populations explode and they may be forced from safe-harbor. These bugs are oval-shaped and small more than a fifth of an inch-long and usually coated in a material. Unlike scale bugs, which can not shift once they reach the adult phase, mealybugs are gradually cell. Mealybug injury on azaleas seems on final leaves and leaf die-back as distortion and leaf yellowing.
Azalea Bark Scales
Azalea bark scale utilizes the same sort of coating and is comparable in look to some mealybug. Unlike the mealy bug that is usually grayish, azalea bark scale is red under its coating. Scale insects are immobile in the phase, in order that they could appear as waxy or cottony growths. Leaf distortion is seldom a problem, although like mealybugs, azalea bark scales cause yellowing of leaves and die-back.
Honeydew
Honeydew is a material secreted by azalea bark scales and mealybugs as they feed. Usual figures of ants are the first indication that the azalea is infested with scale insects or mealybugs. Ants protect them using their lives in trade for his or her waste honeydew and farm these insects. Controlling ants is a a great way to strategy to keep populations under control — when they’re unguarded normal predators like lady bugs gorge on the bugs that are immobile.
Sooty Mildew
Honeydew secreted scale colonies or by big mealy bug ultimately grows mould. Mildew is very harmful for crops. These colonies that are black can become so thick they interfere leading to the demise of the azalea. Treat mildew using a generalpurpose fungicide when it is dense or widespread. Scale populations and controlling mealy bug removes the the meals supply for this particular fungus.

Knock mealy bug populations that are mild from your azaleas having a blast of water from a hose. You’ll be able to prune locations of the plant that seem to be seriously infested with mealybugs provided that you do not eliminate mo Re than about 1 / 4 of the plant off.
Treating Scales and Mealybugs
Mealybugs and scale bugs are handled utilizing the sam-e techniques and respond to a number of pesticides, including horticultural oils and soaps. The the difficulty comes from your azalea.
