Common Diseases of Money Tree and Effective Control Methods

The name of the money tree is deeply loved by the general public. In addition, its plant form is beautiful, its leaves are bright green, and its trunk is club-shaped. Potted plants are suitable for indoor arrangement and beautification, so it has developed very quickly in China's flower market. Therefore, Zhongdiwang has compiled the control methods for common diseases of money tree, listed in detail below for everyone's reference.

Control methods for root (stem) rot of money tree:

First: keep the cultivation environment of the money tree dry and cool, and pay attention to the disinfection of the growing medium and the site.

Second: before transplanting semi-finished money trees, spray the head of the money tree with procymidone to prevent the harm of gray mold fungus.

Third: before planting the money tree, use a sharp knife to cut off the bruised and rotted tissue at the top of the main root, then spray the wound with procymidone, let it dry, and then plant.

Fourth: one week after planting the money tree, when the medium in the pot gradually dries, the healing tissue has formed, and new roots have begun to grow, spray the bare stem of the money tree with propamocarb, dimethomorph, or zinc manganese metalaxyl-mancozeb (Ridomil-MZ), preferably so the solution runs down the stem into the potting soil. After that, use fungicides such as dimethomorph, hymexazol, Ridomil, or ethylicin in rotation once a week.

Fifth: if disease occurs in a cultivated money tree, spray with propamocarb, hymexazol, Ridomil, or ethylicin; the general efficacy lasts about two weeks. If the weather is still unfavorable, another different agent must be sprayed to prevent the development of resistance. If any rotting plant is found during this period, it should be discarded immediately.

Control methods for leaf blight of money tree:

First: if diseased leaves are found on the money tree, they should be removed promptly and destroyed.

Second: during the cultivation of the money tree, maintenance and management should be strengthened, with timely watering and fertilizing. In each growing season, foliar fertilizer can be applied 2-3 times, such as 0.5% nitrogen potassium dihydrogen phosphate or a 200-fold solution of dual-effect micro-fertilizer.

Third: when money tree seedlings are loaded for transport, protective fungicides should be sprayed on the leaves, such as 70% chlorothalonil 800-fold solution, or 18% copper succinate wettable powder 200-fold solution, or 50% thiram 600-fold solution. Money tree seedlings should be planted promptly, and fertilizer and water management should be strengthened to prevent dehydration and nutrient deficiency.

For planted money trees, spray 50% carbendazim 800-fold solution, or 70% chlorothalonil 800-fold solution, or 75% thiophanate-methyl 1500-fold solution every 10-15 days.

The above is about the cultivation techniques of money tree. I hope it can help everyone. For more details, please follow Huinong Xuetang.

Common Diseases of Money Tree and Their Control

    The money tree has palmate leaves, with 7-11 leaflets, oblong to obovate. There is also a horticultural variety, the variegated money tree. Because the name of the money tree is very popular among merchants and ordinary citizens, and because its plant form is beautiful, its leaves are bright green, and its trunk is club-shaped, it is suitable for indoor arrangement and beautification after potting. Therefore, in recent years it has developed very quickly in China's flower market. During festivals, hotels, restaurants, merchants, and citizens often rush to buy it for good luck and good fortune.

    During the growing season of the money tree, if ventilation is poor, red spider mites and scale insects are likely to occur, so observation should be strengthened. Once pests are found, they should be removed promptly or sprayed with pesticide.

    Common diseases of the money tree include root (stem) rot and leaf blight.

    1. Root (stem) rot. This is a common disease that seriously harms the money tree, also known as rot disease. Control methods:

    (1) Keep the cultivation environment dry and cool, and pay attention to the disinfection of the growing medium and the site;

    (2) After semi-finished products are taken out of the cabinet and unloaded to the operation shed, spray the head of the money tree with procymidone to prevent the harm of gray mold fungus;

    (3) Before planting, use a sharp knife to cut off the bruised and rotted tissue at the top of the main root, then spray the wound with procymidone, let it dry, and then plant;

    (4) One week after planting, when the medium in the pot gradually dries, the healing tissue has formed, and new roots have begun to grow, spray the bare stem of the money tree with propamocarb, dimethomorph, or zinc manganese metalaxyl-mancozeb (Ridomil-MZ), preferably so the solution runs down the stem into the potting soil. After that, use fungicides such as dimethomorph, hymexazol, Ridomil, or ethylicin in rotation once a week;

    (5) If Pythium is active, spray with propamocarb, hymexazol, Ridomil, or ethylicin; the general efficacy lasts about two weeks. If the weather is still unfavorable, another different agent must be sprayed to prevent the development of resistance. If any rotting plant is found during this period, it should be discarded immediately.

    2. Control methods for leaf blight:

    (1) Remove diseased leaves promptly when found and destroy them;

    (2) During the cultivation of the money tree, maintenance and management should be strengthened, with timely watering and fertilizing. In each growing season, foliar fertilizer can be applied 2-3 times, such as 0.5% nitrogen potassium dihydrogen phosphate or a 200-fold solution of dual-effect micro-fertilizer;

    (3) Before seedlings are transported from the south to the north, spray protective fungicides on the leaves, such as 70% chlorothalonil 800-fold solution, or 18% copper succinate wettable powder 200-fold solution, or 50% thiram 600-fold solution. After arriving in the north, they should be planted promptly, and fertilizer and water management should be strengthened to prevent dehydration and nutrient deficiency. In southern regions, cultivation of the money tree can begin from the rainy season, spraying 50% carbendazim 800-fold solution, or 70% chlorothalonil 800-fold solution, or 75% thiophanate-methyl 1500-fold solution every 10-15 days. In addition, the main pest is the sugarcane borer moth. This insect is a new record in China, and it is mainly the larvae that harm the money tree; it can also harm poinsettia, Polyscias, and Schefflera.

    Many people come to the money tree because of its name. While planting the money tree well, attention must also be paid to its disease control. By following the above disease control measures, the money tree can be effectively protected from viral damage.

Common Disease Control of Money Tree

1.  Root (stem) rot

Symptoms: the stem base to the root turns blackish brown and rots, and the young leaves lose vitality and wither.

Control methods: (1) Ventilate promptly and keep the cultivation environment dry and cool. (2) Pay attention to the disinfection of the growing substrate and flower pots. (3) After transplanting, remove the bruised and rotted tissue at the top of the root, then spray the wound with procymidone, let it dry, and plant. (4) In the early stage of disease, spray the aboveground part every 10 days with 50% thiram wettable powder 1000-fold solution, or 70% thiophanate-methyl wettable powder 800-fold solution, and drench the underground part 2 to 3 times with 70% mancozeb wettable powder 400 to 600-fold solution. 5. If Pythium is active, spray with propamocarb, hymexazol, ethylicin, etc.

2. Leaf blight

Symptoms: in the early stage, blackish brown spots appear, and inside them gray or dark brown lesions resembling sunscald form. On older lesions, black powder can be seen.

Control methods: (1) Remove diseased leaves promptly when found and destroy them. (2) Strengthen maintenance and management, with timely watering and fertilizing. In each growing season, foliar fertilizer can be applied 2 to 3 times, such as 0.5% potassium dihydrogen phosphate or a 200-fold solution of dual-effect micro-fertilizer. (3) In the early stage of disease, use 75% chlorothalonil wettable powder 800-fold solution, or 50% thiram wettable powder 600-fold solution, or 50% carbendazim wettable powder 800-fold solution, or 75% thiophanate-methyl wettable powder 1500-fold solution.
