The silver flower of the honeysuckle is the dry flower bud or the first flower of the honeysuckle plant. It is a commonly used bulk medicine, mainly distributed in Guangxi Province. The mountain silver flower has the functions of clearing away heat and detoxifying, cooling and dispersing wind and heat, and can be made into various kinds of proprietary Chinese medicines, and is also widely used in food, beverage, health care products, veterinary and the like. The previous section introduces the cultivation techniques, and now introduces the prevention and control technology of the mountain silver flower pests.
In Yunnan, there are mainly carrots, microtubules, flowers, horses, cotton, and powdery mildew (three insects and one disease).
(1) carrot microtubules
Carrot microtubules are of the genus Homoptera. The body length is 1.5 to 1.8 mm, yellow-green, and there is a thin layer of white powder on the body surface. In the spring when the plants are germinated to flowering, the sap of the stalks and the buds on the back of the young leaves and the buds of the buds cause thickening, chlorosis, curling and twisting, and the flower buds are damaged, which can cause deformity and seriously affect the yield and quality.
Control method:
1 carrot microtubules with wings before moving into the yellow sticky board.
2 In the peak period of Ruoqiang, alternate use of various pollution-free pesticides, 0.36% of matrine water 1000 times solution, 1% azadirachtin emulsifiable concentrate 1000 times solution and 1% celangulin EC 2000 times solution And other plant-derived insecticides.
(2) Flower Horse
The flower scorpion is a genus of the genus Diptera. The adult body is 1.3 mm long, the female is light brown to brown, the male is milky white to white; the last nymph is 1.2 to 1.6 mm long and orange. In the spring and autumn flowering period, the nymphs and adults gather on the back of the young leaves, the buds and the flower buds to suck the juice, causing the flowers to fade early.
Control method:
1 Spring mountain silver flower is in front of the bud, hanging yellow sticky insect board.
2 In the peak period of the flower nymph, the nymphs are alternately rotated and used for the prevention and control of various pollution-free pesticides. Because the flower thrips and aphids are sucking pests, the control agents can refer to the agents used to control the mites.
(3) Cotton dew tail
The cotton stalk is a coleoptera. The larvae are 3 mm long and grayish yellow; the adult body is 6 mm long and yellowish brown. Insects and larvae inhabit the petals, feeding on pollen, flower, ovary, and petals, and the damaged petals are withered in advance.
Control method:
1 According to the insect's suspended animation, a polyethylene film can be laid under the canopy in the morning or on a cloudy day, artificially shaken and captured, and the artificially removed artificially removed flowers are burned;
2 Hanging the vibration frequency trap light to trap the adult.
3 Preparation of sugar, vinegar, wine liquid to trap adult.
4 Spray the 1% matrine water 1500 times solution or 1% celangulin EC 2000 times solution or 3% acetamiprid emulsifiable oil 1500 times solution during the peak period of cotton dew tail, ie August-September. The chemical is chemically controlled.
(4) Powdery mildew
Powdery mildew is one of the important diseases of the mountain silver flower, which can cause significant losses when it occurs seriously. It is easy to occur in the hot and rainy season from April to June every year. At this time, it is the flowering season of the mountain silver flower. After the plant is damaged, the flower bud stops growing, twists and even falls off. The pathogen is Microsphaera lonicerae (Wint.), and the pathogen invades directly from the epidermis of the plant. The leaves appear chlorotic yellow spots on the initial onset of the leaves, and white powder appears on both the front and the back of the lesion. Leaves with local onset, diseased leaves curled. The weather is fine, the lesions gradually expand to the whole leaf, and the diseased leaves become yellow and fall off. After the young shoots are infected, the surface is also covered with white powder, and the diseased branches are curled and deformed. After the flower buds, flower stalks and petals are sick, the surface is covered with white powder, curved and deformed.
Control method:
1 Strengthen the management of fertilizer and water, improve the permeability, and make the tree strong.
2 Cut off the seriously diseased leaves and destroy them.
3 In the spring, the flower buds of the mountain buds are often inspected before the germination. Once the powdery mildew is found, use 4% tetrafluoroetherazole water emulsion 1500 times or 32% acetaminophen WP 1200 times or 37% enestrobin. A wet powder 1000 times solution or a 55% propiconazole water agent 1200 times is sprayed on the diseased plant. The above-mentioned agents should be used alternately every 5 to 7 days, and sprayed 2 to 3 times.
The above is the cultivation technology of the mountain silver flower pests and diseases, I hope to help you. If you want to know more about agricultural technology, please pay attention to the Hui Nong School!
