There are worms, green worms and plant leaves in the potted plants in the laboratory. How to kill pests fastest and most effectively? It's urgent

1, isolation method Now move the plants to a place and isolate them with gauze. Existing defects must be removed manually.

2. Another method is to find some fresh tender vegetable leaves and spray them with imidacloprid (systemic pesticide) and ordinary sugar water (such as lotus white and Chinese cabbage) to attract insects (especially soil pests that come out during the day and night) to eat the vegetable leaves first. If not, don't use it. Watch out for flies!

3. Rational application of phosphorus and potassium fertilizer is beneficial to strengthening seedlings and preventing diseases.

In addition: black things may be aphids or excrement. The harm of aphids will cause pinprick-like spots on leaves (under a magnifying glass), but you can wipe them off no matter what kind.

If you eat leaves, the source of insects (flying insects and soil) can grow again. Pay attention to disease prevention through reasonable fertilizer and water pipes!
