What are the pest and disease control methods for the golden spider lily?
1. Anthracnose: Bulbs
Before planting, soak the bulbs in a 0.3% copper sulfate solution for 30 minutes, rinse with water, let them dry, and then plant.
2. Tobacco cutworm
It generally causes damage from late spring to November, and can be controlled with 5% fipronil suspension concentrate at 2500 times dilution or 1000 times dilution of Wanling.
Alright, that is all for the introduction to growing the golden spider lily. The red spider lily is well known because its flowers and leaves never meet in life after life, so whenever the red spider lily is mentioned, everyone can quickly recall it. But when people come across the golden spider lily, they often call it "yellow red spider lily." After reading today's introduction, please do not mistake it again in the future.
Pest and Disease Control of the Golden Spider Lily
Anthracnose of the Golden Spider Lily and Its Control
Anthracnose symptoms: It causes the branches and leaves of the golden spider lily to wilt or die.
Anthracnose control: Before planting with bulbs, first soak them in copper sulfate solution for half an hour, rinse clean with water, let them dry, and then plant. Spray carbendazim once every half month, and in the early stage of the disease, spray with benlate.
Tobacco Cutworm of the Golden Spider Lily and Its Control
Tobacco cutworm symptoms: The larvae of the tobacco cutworm damage leaves, flower buds, and fruits, gnaw away the fruit flesh, and hollow out the seeds. It generally occurs in late spring and November.
Tobacco cutworm control: Fipronil or Wanling can be used for control.
Spider Lily Noctuid Moth of the Golden Spider Lily and Its Control
Spider lily noctuid moth symptoms: The larvae of the spider lily noctuid moth invade the plants of the golden spider lily, hollow out the leaves, and also directly bore into and feed on the inside of the bulbs. Large amounts of green or brown frass pellets are left at the affected parts of the plant.
Spider lily noctuid moth control: If neatly arranged eggs are found on the undersides of leaves, remove them promptly; overwintering pupae can also be dug out by turning the soil in early spring or winter; when the pest occurs, insecticides such as Lorsban or phoxim emulsion can also be sprayed, preferably in the morning or evening when the larvae come out to move and feed.
Thrips of the Golden Spider Lily and Their Control
Thrips symptoms: Thrips suck nutrients at the leaf-bearing part of the bulbs, causing the leaves to lose their green color.
Thrips control: Imidacloprid and Aimeile can be used in rotation as sprays for control.
Growing Methods and Pest and Disease Control Knowledge for the Golden Spider Lily
The golden spider lily, also known as iron-colored arrow, yellow-flowered spider lily, etc., is a perennial herbaceous plant of the genus Lycoris in the amaryllis family. In gardens, it can be used as understory groundcover flowers, planted in groups in flower borders, or planted in natural style among rocks. Because it blooms when it has only leaves, it is best paired with other more shade-tolerant herbaceous plants. It has features such as sturdy scapes and long flower stems. Now let us take a look together at the cultivation methods for the golden spider lily!
Growth Habits of the Golden Spider Lily
The golden spider lily likes sunny and moist environments such as shady damp hillsides, under rocks, and beneath stone cliffs, but it can also tolerate semi-shade and dry environments, is slightly cold-tolerant, and has quite strong vitality. It has no strict requirements for soil, but if the soil is fertile and well-drained, the flowers will be especially abundant. It is distributed in Fujian, Taiwan, China, Hubei, Hunan, Guangdong, Guangxi, Sichuan, and Yunnan in China, and also in Japan and Myanmar.
Propagation Methods of the Golden Spider Lily
1. Bulb division propagation: Division is the simplest and most commonly used propagation method for the golden spider lily. During the dormant period or after flowering, dig up the plant, remove the offsets attached near the mother bulb, and plant them. They can bloom after about one or two years.
2. Bulb cutting: Cut the cleaned bulb base into eight sections in a star shape, with a depth of 1/2 to 2/3 of the bulb length. After disinfection and drying in the shade, insert them into moist sand, perlite, or other substrates. After separation and cultivation, they can become seedlings.
3. Tissue culture: Tissue culture of the golden spider lily uses MS medium, with flower scapes and ovaries collected as explant materials. After culture, callus tissue can be produced at the cut surface, adventitious roots can form after 1 month, and adventitious buds can form after 3 to 4 months.
Growing Methods for the Golden Spider Lily
1. Temperature: The golden spider lily likes warmth, is not highly cold-tolerant, and is also not very tolerant of high temperatures. Therefore, during cultivation, the temperature must not exceed 30 degrees, nor be lower than 8°C, and the average temperature must be kept at least around 24 degrees.
2. Watering: The golden spider lily likes moisture, especially during the growing period, when it should be watered frequently. Always pay attention to keeping the soil moist, but at the same time do not water too much, to avoid waterlogging, which can cause the plant's bulbs to rot.
3. Fertilizing: Under normal circumstances, fertilizing the golden spider lily 2 to 4 times a year is enough. The first time is before flowering, applying organic fertilizer or compound fertilizer. The second time is after flowering at the end of October, applying nitrogen fertilizer and phosphorus-potassium fertilizer.
Pest and Disease Control of the Golden Spider Lily
1. Anthracnose: A common disease of the golden spider lily is anthracnose. Before planting the bulbs, soak them in a 0.3% copper sulfate solution for 30 minutes, rinse with water, let them dry, and then plant. Spray 50% carbendazim wettable powder at 500 times dilution once every half month for control. In the early stage of the disease, spray with 50% benlate at 2500 times dilution.
2. Tobacco cutworm: The tobacco cutworm mainly damages leaves, flower buds, and fruits as larvae, gnawing on the leaf flesh and boring into flower scapes and seeds. It generally causes damage from late spring to November, and can be controlled with 5% fipronil suspension concentrate at 2500 times dilution or 1000 times dilution of Wanling.
3. Spider lily noctuid moth: Overwintering pupae can be dug out by turning the soil in winter or early spring to reduce the pest population base. When it occurs, spray Lorsban at 1500 times dilution or phoxim emulsifiable concentrate at 800 times dilution. Choosing to spray in the morning or evening when the larvae come out to move and feed gives better results.
4. Thrips: Thrips mainly suck nutrients at the leaf-bearing part of the golden spider lily bulbs, causing the leaves to lose green. This is especially found in large numbers after the fruits mature. It can be controlled by rotating sprays of 25% imidacloprid at 3000 times dilution and 70% Aimeile at 6000 to 10000 times dilution.
