Solutions: For less serious cases: Remove beetles, nymphs, and eggs. Remove all life stages of the beetles and kill them by placing them in a bucket of warm, soapy water. This can be done more easily by placing the bucket under affected leaves and shaking the plant. This method is most effective in the afternoon when leaf beetles are more active. Always dispose of insects in a sealed bag or container to avoid escape and spread. To treat more serious infestations: Apply organic insecticides. Use naturally-derived insecticides before moving on to synthetic insecticides. Neem oil and pyrethrum are naturally-derived insecticides that should be applied following label instructions. Apply synthetic insecticides. Examples of insecticides effective for leaf beetles include carbaryl, permethrin, and bifenthrin. Apply insecticides according to label instructions.

Solutions: Follow these steps to revive plants with abnormal leaves. Remove damaged leaves: Plants can recover from damage when given the time to do so. Remove any deformed leaves so they don't continue drawing energy from the plant. This also creates room for healthier ones to grow. Stop using herbicide: Though herbicide damage is challenging to diagnose, gardeners can potentially prevent deformed leaves by not using any and by strictly following manufacturers instructions. Spray insecticide: Prevent pests from inhabiting plant leaves by spraying with insecticide regularly and practicing good natural pest prevention techniques. Apply a balanced fertilizer: Solve nutrient deficiencies and excesses by using a well-balanced fertilizer (organic or conventional both work) before planting, and consider topdressing when signs of stress are apparent. Fix watering schedule: If plant leaves are curled downward due to too much or too little water, adjust the watering schedule so the soil is moist, but not damp. Remove infected plants: If the plant has succumbed to a viral infection, not much can be done to revive it. Remove and destroy all compromised plant material to prevent spread to other plants.

Solutions: In the case of mild disease symptoms: Remove diseased leaves immediately. Also remove any foliage on the ground near the plants, including leaves without the disease. Take care not to touch healthy foliage during removal to avoid spreading. It is best to remove leaves in dry, cool weather. When holes and spots are numerous, and leaves start to drop, take these actions immediately. Remove diseased leaves right away. Just like in mild cases, remove all foliage on the ground near the plant. Avoid touching non-diseased foliage, and only remove leaves when they are dry. Apply fungicide and bactericide. Apply a copper-based fungicide. Spray young leaves about once every week. It's best to apply these products in spring when damage is beginning. After mid-summer, they will have little benefit.

Solutions: Leaf Weevils are relatively easy to control once their presence is discovered. Here’s what to do: Spray the foliage with an insecticide Place sticky traps around the lower trunks of fruit trees and other woody plants. Weevils can’t fly, and have to crawl up the plants when they emerge from the soil. Dig into the soil around plants with a garden fork and remove and dispose of any larvae. Let chickens roam around the garden, as they love to feed on weevil larvae.
