Chrysanthemums are perennials that bloom in autumn and the summer. Commonly developed in both containers and as landscape plants, chrysanthemums are vulnerable to different insect infestations that usually harm attractiveness and the wellness of the plants. Extracting huge quantities of sap in the plant tissue sucking pests generally prey on chrysanthemum foliage and creating the mum leaves to twist, curl or change yellow. Cultural, chemical and biological controls can help treat and prevent insect infestations in your mums.
Chrysanthemum Aphids
Aphids are small dark brown to black insects that pierce the plant tissue and suck the juices out. Populations of aphids that are feeding can result in shoot development and leaves. Aphids exude a sticky substance called honeydew. Sooty mould pathogens change the leaves black to look at and often feed on the honey-dew.
Chrysanthemum Gall Midges
Chrysanthemum gall midges are small flies that seem like gnats with long antennae that are disproportionately. Females lay their eggs. When the eggs hatch, the larvae kind small pimple-like galls along with the leaves and bore into the plant tissue. The larvae feed inside of the galls, creating the plant tissue to become distorted.
Two-Spotted Spider Mites
Two-spotted spider mites may be small, however they are able to inflict serious injury. These spider mites pierce the chrysanthemum leaves and suck the sap out. Leaves produce yellow places that are small and usually appear dusty. Mums that are infested create distorted and blossoms leaves. The two-spotted spider mites spin great webbing under leaves, between the stems as well as on flower buds that were rising. In the event that you suspect a spider mite infestation for webbing inspect your mums.
Chrysanthemum Leafminers
Leafminers are extremely tiny, dark flies. Females lay their eggs on the lower of mum plant leaves. When the eggs hatch, the larvae penetrate the leaves the leaves, or mine. The action that is feeding produces winding, light-green to trails in the leaf tissue. Severe leaf miner infestations usually cause the leaves droop down along the stems and to dry.
Cultural Controls
Check all transplanted and new chrysanthemums for bugs before planting. Prune out any leaves that are infested and discard them instantly. Never compost any chrysanthemum plant tissue infested with pests. Reduce populations by squirting your mums out of your garden hose having a powerful spray of water every-other day. Be certain to squirt your mums which means that your plants dry off by night. High amounts of nitrogen market reproduction, therefore never use a fertilizer that contains nitrogen than required.
Chemical Controls
Use administration methods only as a last resort. Insecticides kill-off all the insects that are beneficial together with the pests. Insecticidal soaps and neem oils are both poisonous chemical options for chrysanthemum pests that are managing. Always follow the instructions on the label for the most readily useful outcomes of the product’s.
