CATDOLL : CATDOLL: How to remove small red spiders growing on asparagus fern

(1) Soak citrus peels in 10 times the amount of water for a day and night, filter and spray on the plants to prevent aphids and red spiders. If you water the soil, you can prevent nematodes in the soil.

(2) Mix 15 grams of laundry detergent, 15 milliliters of 20% caustic soda, and 7.5 kilograms of water and spray. Check after one or two days. The mortality rate of adult and nymph red spider mites is 94%-98%.

(3) Take 50g of wood ash, add 2500g of water and stir thoroughly, soak for two days and nights, filter, then add 3g of washing powder and mix well, spray once a day for three consecutive days, and spray again for three days every week. This can eliminate the second generation of pests and can also prevent and control piercing-sucking pests such as aphids, red spiders, and scale insects. Putting it in soil can prevent and control maggots.

(4) Light a mosquito coil and place it in the pot of diseased plants. Tie the pot tightly with a plastic bag. After about an hour of fumigation, both eggs and adults can be killed. Simple method: Spray water on the leaves.

Cultivation points:

Temperature: Asparagus fern likes a warm environment, and the suitable temperature for its growth is 15℃-25℃. It will stop growing when the temperature is higher than 32℃ in summer. In winter, the temperature should be kept above 10℃, and it will be damaged by frost if it is lower than 5℃.

Light: Asparagus fern prefers a semi-shaded environment, and is best placed in an indoor room with diffused light. Except for winter, it should not be placed in direct sunlight in other seasons, especially in summer, and must not be exposed to the scorching sun. It is afraid of both wind and rain during the flowering period, and good ventilation should also be paid attention to, otherwise it will cause the flowers to fall without producing seeds.

Water: Asparagus fern likes moisture, but avoid watering too much, because too much water will cause the root system to rot. The higher the air humidity, the better. In hot weather, you should often spray water on the ground, branches and leaves around the plant to increase the air humidity. The pot soil should not be too dry, otherwise it will wither.

If there are small red spiders on the asparagus fern, you need to use drugs to kill them. There are methods on the Internet to kill insects with garlic juice, chili powder or laundry detergent, but these methods are not effective and cannot achieve the purpose of radical treatment. They can only achieve temporary expulsion and will promote their large-scale reproduction and harm plants.

1. This insect is very small, less than 1 mm, round or oval, orange or reddish brown. It is difficult to find due to its small size. Once it is found, the damage to the asparagus fern is often quite serious. This insect uses its mouthparts to pierce the leaves and suck the juice, which destroys the chlorophyll, causing the leaves to appear grayish yellow spots or patches, orange leaves, fall off, or even fall off completely.

2. Chemical control: Apply 4000-5000 times uniform spray of dicofol, 1000-1500 times liquid of 40% dicofol emulsifiable concentrate, 2000 times liquid of 20% cypermethrin wettable powder, 2000 times liquid of 15% cypermethrin emulsifiable concentrate, 6000-8000 times liquid of 1.8% cypermethrin emulsifiable concentrate, etc. to achieve ideal control effects.

Note: This type of drug is poisonous and should be used with caution. Dichlorvos cannot be used on this pest because it cannot kill the red spider but will accelerate its reproduction speed.

I am like the original poster. I bought Kalanchoe and found not too many spider mites when I woke up this morning. I wonder if the original poster's asparagus fern has many spider mites. If not, remove them first. Then, you can soak tobacco in water for an afternoon and apply the water to the affected areas. Be sure to be careful. If there are many spider mites, it is necessary to spray pesticides. You can find them at the flower market. Don't use the ones with a strong smell and strong toxicity. They are not good for the plants or you. I just applied tobacco water on the leaves of the asparagus fern. I don't know if there will be any tomorrow. I hope the original poster's asparagus fern will grow better and better!

There is a special medicine for treating red spiders. Just spray it once or twice. It is usually sold in the flower and bird market for two or three yuan. You need to buy a spray bottle yourself.

After soaking tobacco in water overnight, use a brush to apply it to the areas where red spider mites grow.
