Disease and insect pest control of iron chopsticks

1. Aphids

Aphids are the most common pest and disease, and of course they are also the main pest and disease of iron chopsticks. Generally, aphids will first invade the back of the flowers and leaves of the iron chopstick plant. Although aphids are very small, they can be seen clearly with the naked eye. If not controlled in time, aphids will suck the leaves, causing the leaves of the iron chopsticks to turn yellow and dry, and in severe cases, they will wither.

One of the methods to prevent and control aphids is to use aphid flies, which will eat the larvae of aphids, and the prevention and control effect is relatively good, but this is only suitable for places where large areas of iron chopsticks are planted.

Another method is to remove the aphids with your fingers, but this method only treats the symptoms and not the root cause.

There is another method that is most convenient to implement in home cultivation, which is to use soapy water or pesticide spray to control aphids. Generally, if aphids are found, you can spray once a week, which can achieve good control effects.

2. Black spot disease

In addition to aphids, black spot is also a common disease. The main symptom of black spot disease is the appearance of dark brown spots on the surface of the leaves of the helleborus. If not treated in time, the spots will expand to the entire leaf. The formation of black spot disease is mainly caused by the invasion of black spot disease bacteria. This disease is easy to occur in the case of poor ventilation and stagnant water.

If you want to prevent and control black spot disease, you must first destroy the leaves of the iron chopsticks that are infected by black spot disease, so that the number of pathogen spores in the soil can be reduced. Then use fungicide to spray once every half a month, which will be very effective in curing black spot disease.

Most plants will be affected by diseases and pests. The first thing to do is to regularly observe your flowers to see if there are any abnormalities. Then, classify the diseases and pests according to these phenomena, and use different methods to prevent and control them so that they can get treatment in time. Therefore, when growing iron chopsticks, you must take good care of them to harvest healthy plants.
