Chokeberry (Aronia) is recognized for its colorful berries in red, purple or black. Few people do because they’re so bitter they induce choking even though it is possible to technically consume the berries next to the shrub. Instead, the shrub is cherished because of its value with tiny pink or white clusters of flowers and colored. Sunset zones that are developing differ by species. Even though several insects can cause small problems shrubs have no key pest issues.
Aphids
These tiny, pear shaped, soft-bodied pests use their mouthparts to pierce stems and leaves on shrubs and eat up the liquid from from their website. Aphids have a pair of tube-like structures, or cornicles, protruding from the back of the bodies. They could be waxy or woolly searching, and might be red, yellow, brown, green or black. Aphids can cause distortion of leaves yellowing and stunting of shoots, and sticky honey-dew is left behind by them. Spray bottoms and the tops of leaves having a constant stream of water to eliminate aphids or use neem oil, insecticidal soap or a narrow-range oil including a superior or supreme paraffinic -kind oil.
Fall Webworm
Grey caterpillars or brown with hairs growing from orange or black places, fall webworms wrap themselves across the conclusion of branches on shrubs in mid- to late summer in a tent of silk. They feed on the foliage between leaf veins. Prune branches when you place these 1-inch spinosad or pests, or spray with Bacillus thuringiensis.
Apple Maggot
In addition to apple trees, apple maggots are also hosted by chokeberry shrubs. These 4- to 5-millimeter-long black flies have a white spot on their thorax and clear wings. Apple maggots that are female and males have four bands on their abdomens and three, respectively. They bore creating premature fruit drop and leaving tunnels under the the epidermis that turn brown. These pests aren’t identified in every area of California, in accordance with the University of California Integrated Pest Management Plan web site. Remove fruit from around your shrubs. You can spray spinosad on the shrubs from mid-July and repeated every seven to 10 times as required.
Scales
Closely connected to aphids, scales are pests that seem as black or brown bumps on branches and leaves. They can be either delicate scales or scales, and measure about 1/8 inch-long. The leaves on shrubs suffering from scales will turn yellow and fall, while delicate scales leave a path of honey-dew that attracts bees, flies, wasps and ants and encourages black sooty mildew. Remove scales from shrubs that are chokeberry manually or spray with a oil or insecticidal soap.
