What to Do When Money Tree Leaves Turn Yellow? Common Pests and Diseases and Their Control Methods

1. Leaf Spot Disease:

Leaf spot disease is a fungal disease. In the early stages of infection, small brown spots appear on the leaf margins or leaf tips. In the later stages, the lesions turn gray or grayish-brown, and under humid conditions, small black dots develop on the affected areas.

Control methods:

1. If the branches and leaves of the money tree are too dense, it will lead to poor ventilation, and poor ventilation easily causes the occurrence of pests and diseases.

2. Once leaf spot disease is detected, spray in the early stages of infection with 65% Iprodione wettable powder or 50% Thiophanate-methyl? sulfur suspension 800 times dilution, 30% basic copper sulfate suspension 400 times dilution, 75% Daconil wettable powder 700 times dilution, etc. Once every 7-10 days.

Money Tree Pest and Disease Control Knowledge

Yellow Leaves

First, water-yellow: caused by excessive watering. Its characteristic is that old leaves show no obvious change while young leaves turn yellow. In this case, watering should be stopped immediately.

Second, drought-yellow: caused by lack of water and drought. Its characteristic is that old leaves turn yellow first from the bottom up. If the water shortage lasts a little longer, the entire plant's leaves will turn yellow, or even die. Water should be applied promptly.

Third, fertilizer-yellow: caused by excessive fertilizing or too high a concentration. Its characteristic is that young leaves are thick, glossy, and uneven. Fertilizing should be stopped, and the soil should be loosened and watered.

Fourth, starvation-yellow: caused by insufficient fertilizer, too low a fertilizing concentration, and too long an interval between fertilizing. Its characteristic is that yellowing starts at the young leaves and tender stems. If this phenomenon is observed and fertilizing is not carried out in time, it will also cause the entire plant's leaves to turn yellow or even die. For flowers lacking fertilizer, never apply a large amount of concentrated fertilizer at once, so as to avoid burning the roots.

Fifth, iron-deficiency yellow leaves: For woody flowers in greenhouses, etc., due to large changes in soil fertility conditions, yellow leaf phenomenon often occurs. Its characteristic is that young leaves are obviously affected while old leaves are less so, the leaf mesophyll is yellow, the veins are green, and a typical network pattern forms. It can be solved by applying ferrous sulfate aqueous solution. The method is: mix 7 parts cake fertilizer, 5 parts ferrous sulfate, and 200 parts water into a diluted solution and water with it.

Root Rot

Root rot is a common disease that seriously harms the money tree, also known as decay disease.

Control methods

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

(2) After semi-finished products are taken out of the cabinet and unloaded to the operating 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 rotten tissue at the top of the main root, then spray the wound with Procymidone, and plant after it dries;

(4) One week after planting, the medium in the pot gradually dries, callus tissue has formed, and new roots have begun to grow. Spray the bare stem of the money tree with Previcur, Anke, or zinc-manganese metalaxyl (Ridomil-MZ), so that the solution flows along the stem into the pot soil. Thereafter, use fungicides such as Anke, Turf fungicide, Ridomil, or Ethylicin in rotation once a week;

(5) If Pythium is active, spray with Previcur, Turf fungicide, Ridomil, or Ethylicin. The efficacy generally lasts about two weeks. If the weather is still unfavorable, different agents must be sprayed again to prevent the development of resistance. If any rotting plant is found during this period, it should be discarded immediately.

Leaf Blight

Control methods

(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. Each growing season, foliar fertilizer can be applied 2-3 times, such as 0.5% nitrogen potassium dihydrogen phosphate or 200 times dilution of double-effect micro-element fertilizer;

(3) Before seedlings are transported from the south to the north, spray protective fungicides on the leaves, such as 70% chlorothalonil 800 times dilution, or 18% copper polycarbamate emulsion powder 200 times dilution, or 50% Tuzet 600 times dilution. After arriving in the north, plant them in time, strengthen fertilizer and water management, and prevent dehydration and fertilizer loss. When cultivating money trees in southern regions, starting from the rainy season, spray 50% carbendazim 800 times dilution, or 70% chlorothalonil 800 times dilution, or 75% thiophanate-methyl 1500 times dilution every 10-15 days.

Pests

The main pest of the money tree is the sugarcane borer, which is a new record in China. It mainly damages the money tree as larvae, and can also damage poinsettia, Polyscias, Schefflera, and Hawaiian palm.

What to Do When Money Tree Leaves Turn Yellow? Control Methods for Money Tree Leaves Turning Yellow

Many people like to grow money trees, but do you know what to do when money tree leaves turn yellow and the solutions for money tree leaves turning yellow? Next, the editor will introduce in detail the solutions for money tree leaves turning yellow, to help everyone grow money trees better.

Causes of money tree leaves turning yellow:

1. Excessive watering, no fertilizing for a long time, or changing pots or water causing the loss of nutrient elements, thereby causing money tree leaves to turn yellow. So as long as water and fertilizer are changed in time, it can be effectively avoided.

2. Over-fertilizing. If the money tree is over-fertilized, it will cause the leaves to turn yellow. Stop fertilizing in time and increase the amount of water changed, which can alleviate the yellowing of money tree leaves.

3. Hot and high temperatures. The money tree should not be placed under high temperatures and direct strong sunlight, otherwise it will cause the edges of the money tree leaves to turn yellow. So when this happens, move the money tree to a shady place in time.

4. Excessive shading. Excessive shading will also cause money tree leaves to turn yellow, so it is best to place it in an environment with sunlight but not harsh.

5. Soil and water on the alkaline side. If the water for the money tree lacks soluble iron and other elements that it can absorb, the money tree leaves will turn yellow. So when planting, choose acidic soil and water, and frequently water with alum fertilizer water during the growing period.

6. Ventilation. If the space where the money tree is placed is sealed and unventilated, too much nitrogen fertilizer is applied, the leaves are very luxuriant, and it is not pruned for a long time, insufficient light will cause the leaves to turn yellow. So fertilizing must be reasonable, pruning must be strengthened, and good light transmittance must be maintained.

7. Temperature. If the temperature in winter is too low, it will cause the flower leaves to dry up and turn withered yellow. So the temperature must be controlled in time to maintain better growth of the money tree.

8. Pests and diseases. Leaf spot disease of the money tree will cause the money tree leaves to turn yellow, and in severe cases they will fall off. So the diseases of the money tree must be controlled in time and prevented and treated promptly.
