Will tulips have insects? Tulip pests and diseases

1. Pests

1. Aphids: Aphids are a common pest that are harmful to many plants. It will suck the juice of the plant or eat the tender parts. Once discovered, pesticides should be sprayed in time. Generally, 1000 times diluted Marathon Emulsion or 1000 times diluted Cypermethrin can be used to eliminate it. Spray 1-2 times.

2. Root mites: Root mites can harm plants with bulbs, causing the roots to fall off and the eaten parts to rot and stink. Usually, 1000 times diluted dimethoate emulsifiable concentrate or 4000 times diluted cypermethrin emulsifiable concentrate is used for prevention and control. Since it is in the soil, it must be killed by root irrigation.

3. Thrips: Thrips, which are harmful to tulips, are mainly distributed in southern my country. Its adults and larvae will suck the juice from the leaves, causing them to turn brown and curl up and fall off. Pests are more common in July and August, and should be controlled by spraying 800 times diluted cypermethrin or cypermethrin emulsifiable concentrate.

2. Diseases

1. Sclerotinia disease: When tulips become diseased, yellow or brown circular spots will appear on the scales, and sclerotia will infect the stems. This virus is mostly in the soil, so disinfection should be done before planting. After the disease occurs, the diseased plants should be removed in time and sprayed with Bordeaux mixture or mancozeb for prevention and control.

2. Viral disease: Viral disease can cause the degeneration of tulips. It can harm the leaves and petals, causing spots and, in severe cases, rot. The disease is mainly spread by aphids, so prevention and control should be taken during the growing season. At the same time, the diseased plants should be pulled out and destroyed to avoid cross-infection.

3. Basal rot: Basal rot harms the bulbs and roots of tulips. Small spots will appear at the base of the bulbs, and the bulbs will rot and stink. Generally, it should be harvested early in a dry climate to avoid it being burned. After it pills, it should be soaked in a benomyl solution, which can also help prevent it from disease.
