The specific details are introduced in detail below, and friends troubled by this can take a look.

2. Pest and disease control for dog's tooth flower (pests)

Thrips

Thrips is the collective name for insects of the order Thysanoptera. Its body is relatively small, generally 0.5-2mm in length, and rarely exceeds 7mm. This pest mainly harms the bulb and leaf area of dog's tooth flower, gradually absorbing the nutrients within, which causes the leaves to gradually lose their green color and appear yellow and withered.

Control method: When dealing with this pest and disease of dog's tooth flower, we can use 25% imidacloprid 3000 times solution and 70% Admire 6000-10000 times solution for alternating spray control.

Aphids

Aphids are one of the most destructive pests on Earth, harming many plants, and dog's tooth flower is one of them. The damage of this pest mainly consists of adult and nymph aphids sucking the sap of leaves, stems, tender tips and tender spikes, which causes a large loss of nutrients in the plant and leads to wilting.

Control method: When dealing with this pest and disease of dog's tooth flower, we can use 10% omethoate emulsifiable concentrate 1000 times solution or malathion emulsifiable concentrate 1000-1500 times solution to spray and kill them.

3. Pest and disease control for dog's tooth flower (diseases)

Anthracnose

Anthracnose mainly occurs on the leaves of dog's tooth flower. In the early stage of the disease, many water-soaked yellow lesions appear on the leaves. After expanding, they become oval to irregular brown or yellow-brown lesions. In the later stage, the lesions connect into one piece, causing the leaves to appear withered, and producing small black spots arranged in concentric rings.

Control method: The appearance of this disease is mainly caused by poor ventilation in the growing environment, so we must keep the environment ventilated when growing it. As for treating this disease, we can use 65% zineb wettable powder 600 times solution to spray the affected areas. Generally, spraying once every one week, and it can be cured after 3-4 times.

Black spot disease

Black spot disease is a disease caused by fungi. It mainly harms the leaves, petioles and tender shoots of dog's tooth flower. When the disease occurs, many purple-brown lesions appear on the affected parts, and as time goes on the lesions gradually expand and the color slowly changes, finally causing the plant to gradually wither.

Control method: For this pest and disease of dog's tooth flower, we can use thiophanate-methyl or carbendazim and others to spray the diseased plant. Generally once every 7-10 days, and it can be cured after 2-3 times.

What to do when dog's tooth flower leaves turn yellow - control temperature / apply thin fertilizer / replenish water / supplement light

Dog's tooth flower is a flowering plant with high ornamental value, and it can be seen in various provinces and regions in southern China. However, even if a plant has high ornamental value, yellowing leaves will also affect its overall beauty. So what should be done when dog's tooth flower leaves turn yellow? Let's take a look together below.

1. What to do when dog's tooth flower leaves turn yellow - find the cause

To know what to do when dog's tooth flower leaves turn yellow, we first need to know what causes this phenomenon. Only after knowing the cause can we solve the problem accordingly. Insufficient light and improper watering are both causes of this phenomenon. As for how to solve it specifically, there is a detailed introduction below. Let's take a look.

2. Causes of dog's tooth flower leaves turning yellow (with solutions)

1. Temperature too low

Dog's tooth flower has very high requirements for environmental temperature during growth. This plant is relatively intolerant of cold. If we do not control the temperature well during cultivation and the environmental temperature is too low, it is very easy to cause dog's tooth flower leaves to turn yellow, and if the temperature is too low it can also easily freeze and even kill the plant.

Solution: During the growth of dog's tooth flower, it is very important to let it grow at a comfortable environmental temperature. Its suitable temperature is above 10°C. If it is below this temperature, the leaves of dog's tooth flower will turn yellow, and if it is below 0°C the branches will suffer frost damage, so we must control the temperature well when growing it.

2. Improper fertilization

Fertilizer is one of the main nutrients in the growth of dog's tooth flower. If we fertilize too little or the fertilizer concentration is too high, it will cause dog's tooth flower leaves to turn yellow. If too little fertilizer is applied, it will turn yellow due to insufficient nutrients; if the fertilizer concentration is too high, it will burn the plant and cause yellowing.

Solution: Dog's tooth flower has very high fertilizer requirements during growth, especially after entering the growing period, when its demand for water is very high. Basically it needs to be fertilized once every 7-10 days, so that its leaves can grow large. However, the fertilizer concentration must not be too high when fertilizing. It must be diluted with water first before application. If the concentration is too high, it will easily burn the plant.

3. Insufficient water

In the process of growing dog's tooth flower, especially after it enters the growing period, its demand for water is very high. Especially in summer, if it is not watered for one day its leaves will wilt and turn yellow, and long-term water shortage can also cause the plant to wither and die.

Solution: Dog's tooth flower likes to grow in a warm and humid environment, so in our daily care we should keep the soil moist and not wait until the potting soil is completely dry before watering. In summer, when the weather is hotter, we basically need to water every day, and also often spray water around it to increase air humidity.

4. Insufficient light

Dog's tooth flower is a light-loving plant. If the light is not sufficient enough, its leaves will gradually become dull and lose green, gradually showing yellowing. So for it, light is very important.

Solution: If the yellowing of dog's tooth flower leaves is caused by insufficient light, we had better not immediately move it outdoors for direct sun exposure, but place it in a spot with scattered sunlight for care. After it recovers, let it receive sufficient light.

5. Pest and disease infestation

In the process of growing dog's tooth flower, if cultivation is improper, problems such as pests and diseases are very likely to appear. Such problems are extremely harmful to the plant, not only causing dog's tooth flower leaves to turn yellow, but in severe cases also causing the plant to wither and die.

Solution: If problems such as pests and diseases appear on dog's tooth flower, we must deal with them in time. The specific treatment methods have been introduced in detail in the article on pest and disease control for dog's tooth flower, so I will not repeat them here.
