Trumpet creeper pests: whiteflyHazard manifestationsWhiteflies are small white insects that are difficult to distinguish with the naked eye. At the same time, different stages of the same body can be seen on the plant: adults and larvae. The adults mainly harm young leaves and suck the sap from the leaf flesh; the larvae mainly adhere to the back of the leaves and suck the sap, causing the leaves to curl and dry up. In addition, the branches and leaves released by whiteflies will contaminate the leaves, which can easily cause sooty disease. Prevention and treatment methodsWhen insect pests are found, spray the pesticide in time, spray 40% omethoate, spray once every 7 days, and spray 3 to 4 times continuously. When spraying the pesticide, be sure to spray both sides of the leaves, especially the back side, where a large number of insects will live. Strengthen maintenance at ordinary times, pay attention to ventilation, and spray fungicides once a month. Trumpet creeper pests: aphids, red spidersHazard manifestationsAphids and red spiders are very small and difficult to distinguish with the naked eye in the early stages of the disease. But you would never imagine that a bug as small as a few millimeters can cause a plant of dozens of centimeters to fall down in a short period of time. Don't underestimate them! The insects will suck the sap from leaves, buds and mosaics, affecting normal growth and development. Not only will this affect the appearance, but in severe cases it can cause the entire plant to die. Prevention and treatment methodsThe environment is very important during the maintenance process. Frequent ventilation, ensuring a clean environment, adding phosphorus and potassium fertilizers, and enhancing the plant's disease resistance can reduce the occurrence of pests to a certain extent. When a small number of aphids or red spiders appear on the plants, they can be rinsed with clean water (or scrubbed with soapy water). In serious cases, spray 1 : 1000 times dimethoate solution. |
