Thrips is the collective name for insects of the order Thysanoptera. They are relatively small, generally 0.5-2mm in body length, and rarely exceed 7mm. This pest mainly harms the corm and leaf area of coreopsis, gradually absorbing the nutrients within, which causes the leaves to gradually lose their green color and turn yellow and dry up.

Control method: When dealing with this coreopsis pest, we can use 25% imidacloprid 3000 times dilution and 70% Amello 6000-10000 times dilution for alternating spray control.

Red Spider Mite

Among the pests and diseases of coreopsis, the red spider mite is a relatively common one. Its peak period is every summer, so everyone must pay extra attention at this time. When this pest appears, the plant's leaves will gradually turn yellow and white, and if left untreated for a long time, it will also cause the plant to wither.

Control method: When dealing with this red spider mite pest, we can directly use 40% dicofol emulsifiable concentrate 1000-1500 times dilution for spray killing. Generally, three consecutive sprays can completely kill this pest.

Rust disease is one of the more frequently occurring pests and diseases of coreopsis. This disease mainly threatens the plant's leaves, stems and fruits. When it occurs, many small blister spots appear on the affected parts, and in severe cases the blister spots merge into dense patches, and the plant will rapidly wither and die as a result.

Control method: When rust disease appears on coreopsis, we can use 50% carboxin wettable powder 2000 times dilution to spray it, generally once every 7-10 days, and after 1-2 times it can recover.

Leaf Spot Disease

Leaf spot disease is a disease caused by fungi. Its peak period is every spring and autumn, so everyone must pay extra attention in these two seasons. Leaf spot disease mainly harms the leaves of coreopsis. When it occurs, many round spots appear on the leaves, and the spots gradually expand and become irregular in shape, ultimately causing the plant to gradually wither and die.

Control method: When controlling leaf spot disease, a coreopsis pest and disease, we can use 80% mancozeb 400-600 times dilution to spray the diseased plants, generally once every 10-15 days, and after 1-2 times they can recover.
