Aphids, also known as greasy insects or honey worms, are a common pest that sucks up the sap of plants, causing them to grow poorly. To effectively control aphids, here are three of the things they fear the most:
The first is the seven-star ladybug. The seven-star ladybug is a well-known predatory insect that feeds on aphids. The introduction of the seven-star ladybug to plants with severe aphids can effectively control the number of aphids.
The second is matrine. Matrine is an alkaloid extracted from Sophora sophora, which can damage the nervous system of aphids, causing the aphids to die. The advantage of using matrine is that it does not produce *** to the plant, and at the same time, it can effectively protect the plant from aphids.
The third type is imidacloprid. Imidacloprid is a common insecticide that can cause the aphids to die by interfering with their nerve conduction systems. Imidacloprid has a faster insecticidal effect compared to matrine, but it may have some negative effects on the environment.
To sum up, the three things that aphids are most afraid of are seven-star ladybugs, matrine, and imidacloprid. The use of these methods can effectively control the number of aphids and protect the healthy growth of plants. However, when using these methods, attention needs to be paid to dosage and safety issues to avoid unnecessary negative effects on humans and the environment. Autumn and Winter Check-in Challenge
