What pests does Tigerthorn have?

1. Whitefly

1. Harm: After whiteflies appear, they will suck the juice from the back of the leaves, causing the leaves to dry out, turn yellow, and fall off. Large areas of black powder will also appear on the stems and leaves, affecting the ornamental value and making it look very unsightly.

2. Prevention and control: The most likely reason for the appearance of whiteflies is that it is too hot and stuffy. This aspect needs to be improved by providing good ventilation conditions. It is also necessary to spray with a diluted solution of 40% oxydemeton-methyl emulsifiable concentrate, or a 1000-fold solution of oxydemeton-methyl mixed with dichlorvos. After the agent is sprayed, the black powder on it can be washed off with a strong stream of water.

2. Scale Insects

1. Harm: This is a very common insect pest, which is most prevalent in early spring. It mainly lies on the stems and leaves to suck the juice inside, which will cause poor growth of this part. In serious cases in the later stages, it may cause the Euphorbia milia to wither and die, which has a great impact.

2. Prevention and control: When the number is small, you can first use a small brush to brush it down and remove it manually. It is also necessary to use pesticides, such as 800-1000 times diluted Supu Sha to spray these insects. You can also use homemade ash water for spraying treatment.
