In the growth process of Taxus chinensis, it is possible to have blight, stem rot, white silk disease and Phytophthora. The most serious diseases are stem rot and white silk disease. In two months of cutting, Taxus chinensis is prone to stem rot, especially in July to August when the weather is relatively hot, the heat resistance of Taxus chinensis is weak, which is more likely to lead to the infection of stem rot. The occurrence of white silk disease is generally in the summer when the weather is hot in July and August, after the weather gets cold, the condition will get better.
When the stem rot of Taxus chinensis occurs, it is necessary to carry out sterilization in time and spray Bactericides to reduce the soil temperature, otherwise it will burn the roots of Taxus chinensis seedlings, and it can also increase the fertilizer application to enhance the resistance of Taxus chinensis seedlings. When the white silk disease of Taxus chinensis occurs, we should do a good job in the management of Taxus chinensis, loosen the soil, weeding and fertilizing, and so on. We should clean up the branches and leaves of the disease in time to prevent secondary infection, and then use pentachloronitrobenzene to mix into the yellow heart soil, and sprinkle the disease to the Taxus chinensis, so that we can treat the white silk disease of Taxus chinensis.
Generally, the pests of Taxus are mites, aphids and scale insects, among which aphids are the most harmful. When the weather is relatively mild, aphids are easy to produce. Aphids will eat the roots and leaves of Taxus chinensis, which will seriously harm the growth of Taxus chinensis and even cause the death of Taxus chinensis. We will plant Taxus in greenhouse, greenhouse temperature is very mild, it is easy to have aphid harm.
We can consciously cultivate some natural enemies of aphids, and use natural methods to control aphids. On the other hand, we can use medicaments to kill aphids.
