White pine long insectI haven't visited the little pine tree for two days. I was shocked when I saw it today. The little pine tree, which was in good condition before, is no longer in good condition. It has black insect feces all over its body, and many branches have been bitten off. I was really confused for a moment! If it is not sprayed with pesticides or treated in time, the leaves of the white pine will gradually become hollow and the entire plant will collapse. What are the insects of white pine?This is a very small insect, usually a white aphid, smaller than a sesame seed. In the early stage, only a few will appear on the leaves, which will not have a big impact, but gradually they will cover the branches and leaves densely. Aphids mainly feed on the branches and leaves of the white-flowered pine and leave secretions, which cause dark brown spots to appear on the leaves. They are very harmful and can cause you heavy losses. Pest control of white pineFlower Protector is a commonly used pesticide for succulent pests. Spray it in time when pests are found. If you have children at home, try to spray the pesticide outdoors. After all, it is a pesticide and has a certain degree of toxicity. Four ways to make your own insecticideTake 200 grams of green onion, chop it into pieces and soak it in 10 liters of water for a day and night. After filtering, use it to spray the affected plants several times a day for 5 consecutive days. Crush 200-300 grams of garlic to extract the juice, dilute it with 10 liters of water, and immediately use it to spray the plants. Soak 400 grams of tobacco powder in 10 liters of water for two days and nights, filter out the tobacco powder, add 10 liters of water and 20-30 grams of soap powder when using, stir well and spray on the affected flowers and trees. Add 10 liters of water and 3 kilograms of wood ash, soak for 3 days and nights, then spray the plants. |
