Common Pests of Purple Jasmine and Their Control Methods

Common pests of purple lilies: aphids

Pest symptoms

Aphids, also known as honey bugs and sticky insects, mostly belong to the Aphididae family of the order Homoptera. They are pests with piercing-sucking mouthparts. They often gather on leaves, tender stems, flower buds, terminal buds and other parts, sucking sap, causing the leaves to shrink, curl, and become deformed. In severe cases, they cause the branches and leaves to wither or even the death of the entire plant. The honeydew secreted by aphids can also induce sooty mold disease, viral diseases and attract damage from ants.

Aphid control methods

Kill aphids with laundry detergent: Laundry detergent has a contact killing effect on aphids. Use a brush dipped in a 1:500 ratio solution of laundry detergent and water to scrub the aphids on the branches and leaves of flowers. You can also use a small sprayer to spray it, which can also effectively scrub off the honeydew secreted by aphids.

Regardless of whether you use laundry detergent or other pesticides to kill aphids, you must be careful that if you want to pick purple flowers for consumption in the future, you must wash them several times to ensure that there is no residue of the pesticide before eating them. Otherwise, you will spit out detergent bubbles when you speak, and your stomach and intestines will be attacked by the chemicals.

Common pests of purple lilies: leafhoppers

Pest symptoms

Nymphs or adults use their mouths to suck sap, causing pale white spots to appear on the leaves. When the damage is serious, the spots appear in patchy shapes, or they may pierce the epidermis, causing the branches and leaves to wither.

The harm caused by leafhoppers is not only superficial. They also often spread plant viruses, such as inducing purple lily mosaic disease and purple lily spot disease, which are very annoying.

There are many types of leafhoppers. Flower lovers should pay more attention to observation during daily maintenance. After discovering the insects, they should lure and kill them to prevent their reproduction in time.

Prevention and treatment methods

Spray 2000 times of 2.5% cypermethrin wettable powder, or 800 times of 90% trichlorfon solution, or 1000 times of 50% cypermethrin emulsifiable concentrate.
