How to treat the disease of tortoise back bamboo

Tortoise, also known as Penglai banana, mainly grows in tropical rain forests and is widely cultivated in China. Environmental changes often threaten the health of plants by diseases. So, how to cure the disease of turtle back bamboo?

1. How to cure turtle bamboo disease

Common diseases of Tortoise are gray spot and rust. 70% thiophanate-methyl 1000 times solution or 50% carbendazim 1000 times solution is sprayed to kill the gray spot disease of turtle shell bamboo. At the early stage of disease, spraying 20% triadimefon EC 1500 times or 25% triadimefon WP 1500 times for 3~4 times continuously has effect.

Second, what happened to the yellow leaves of the turtle?

1. Soil hardening

Turtle bamboo is suitable for growth in soil with good permeability. If the soil used is not suitable, or the cultivated soil becomes hardened, it will affect the permeability and drainage performance. In such an environment, it is difficult for the roots of the plant to breathe normally, and it is difficult to discharge water, which will cause yellow leaves. Therefore, it is necessary to do a good job of digging soil or replacing new pots of soil.

2. Irrational watering

It is suitable for growth in wet places, do not water too much when maintaining, too much water will make the roots rot, it will make the leaves yellow. On the contrary, too little watering, long-term lack of water, it will grow poorly, but also yellow leaves. Water should be reasonable, do not water when dry.

3, adjust the temperature

Plants are very afraid of cold, indoor temperature can not be too low, if the temperature of the maintenance environment is below 5℃, plants will be frostbite, but also will lead to yellow leaves. It needs to be transferred to a warm position as soon as possible, and the temperature should be adjusted to about 10 ° C as much as possible.

4. Lack of nutrients

Turtle bamboo in the growth period is the need for appropriate fertilization, if not fertilization for a long time, its leaves will be difficult to form chlorophyll, so it will cause yellow leaves. Some fertilizer should be applied to it as soon as possible, and appropriate amount of alum fertilizer can be applied.
