How to treat the disease of money tree

Money tree, also known as snow iron taro, is an indoor foliage plant, has the role of purifying indoor air, sexual preference for warm, slightly dry, semi-overcast and small annual temperature change environment. So, how to treat the disease of money tree?

1. Brown spot

1. Symptoms: the disease mainly harms the leaves of the money tree. When the disease occurs, there will be small near-round spots on the leaves, the color is grayish brown, and the edge is slightly darker. In the later stage, the disease spot gradually expanded and fused together, so that the leaves withered.

2. Prevention and treatment: remove the diseased leaves in time and destroy them. The leaves should be sprayed with chlorothalonil or carbendazim at the initial stage of the disease. Spray once every 10 days, 3-4 times in a row can be cured.

2. White silk disease

1. Symptoms: it mainly harms the rhizome of the plant. When the disease occurs, the damaged rhizome will produce watery spots. The center of the lesion was slightly sunken and the edge was obvious. In the later stage, the surface of the rhizome was covered with white silk-like hyphae and spread to the soil surface. In severe cases, it can cause the whole plant to die.

2. Prevention and control methods: before planting, use formalin to irrigate the soil and disinfect the soil. In the season of frequent occurrence of white silk disease, methyl thiophanate solution can be used to prevent the occurrence of the disease. In the early stage of the disease, lime powder can be sprinkled around the basin soil. Sprinkle once every 15 days, 2-3 times in a row.

Third, stem rot

1. Symptoms: because the mycelium or chlamydospore or conidia overwintered in the soil, the bacteria-carrying fertilizer and diseased soil were the main sources of primary infection in the following year, and the conidia were produced on the diseased stem for re-infection and spread by water sputtering. moisture retention time is long and easy to occur. In the hot summer, the soil temperature rises, and when the base of the seedling stem is burned by high temperature, the pathogen invades and harms. It is observed that seedlings generally begin to develop disease 10 to 15 days after the end of Meiyu, and then the incidence increases gradually, and the disease stops in mid-September.

2. Prevention and control methods: if necessary, spray 27% copper noble suspension solution or 50% benzene bacteria wettable powder 1000 times solution, 50% methyl thiophanate sulfur suspension solution, 50% chlorothalonil + sulfur suspension 600x solution.

IV. Late blight

The main results are as follows: 1. Symptoms: the late blight of money tree mostly occurs from July to August. Sporangia are produced in the disease part, and zoospores are produced after germination to be infected by wind and rain. High temperature and rain and high humidity are the epidemic conditions of the disease.

2. Prevention and treatment methods: before the onset of the disease, pre-prevention and treatment should be carried out by spraying 27% copper noble suspension 600 times or 30% basic copper sulfate suspension 300 times 400 times. During the peak period of the disease, spray 72.2% Prik water agent 600 times 700 times, 58% metalaxyl ·manganese zinc wettable powder 500 times, 64% poison alum wettable powder 500 times.

For the diseases of the money tree, we need to prescribe the right medicine to the case, but also pay attention to the alternate use of drugs to avoid drug resistance.
