Aphids, red spiders, and scale insects are the three most common types of sucking pests that damage flowers and trees. They endanger the variety of flowers and trees, whether it is woody flowers such as Milan, jasmine, rose, smiling, plum, or herbal flowers such as chrysanthemum, geranium, pouch, etc., are not spared. After many years of exploration and experimentation, the author has summed up some simple and effective prevention methods, which are not only easy to take, but also do not pollute the environment.
aphid
Aphids, also known as armyworms, occur all year round. There are many types of aphids, usually green, yellow, black, and brown. They gather on the buds, young leaves, or twigs of the plants, sucking juice and harming the buds. And petals. The branches and leaves of the damaged plants are yellow and deformed, the flower buds are damaged, and the flowering period is shortened. In severe cases, the plants will die and die.
Control method:
1. Use 50 grams of fresh or dried red pepper, add 30 to 50 grams of water, cook for about half an hour, and spray the affected plants with the filtrate to have special effects.
2. Use 3 to 4 grams of washing powder, add 100 grams of water, stir into a solution, and spray continuously for 2 to 3 times, the control effect is 100%.
3. Add 600 to 800 times of the solution with “Wind Oil†and spray the pests carefully with a sprayer to make the insects get the medicine. The effects of killing pests such as aphids and scale insects are above 95%, and there is no phytotoxicity to plants.
Red spider
Red spider, also known as short-shoulder, is a pest that specifically harms flower leaves. The spider's body is like a needle tip, deep red or purple, and only red dots are visible to the naked eye. Its nymphs are often clustered on the backs and buds of some flowers, sucking the juice by the sucking mouthparts and damaging the plants.
Control method:
1. Soak the citrus peel with water for about 10 times for a day and night. After spraying, spray the plants to control the mites and red spiders. For example, the soil can prevent the nematodes in the soil.
2. 15 grams of washing powder, 15% of 20% caustic soda, 7.5 kilograms of water, sprayed after mixing, and checked after one or two days, the adult and nymph mortality of red spider is 94% to 98%.
3. Light a coil of mosquito coils, place them in the pots of the diseased plants, and then tighten them with plastic bags. After an hour or so of smoke, they can be killed by eggs or adults. This is a good way to save time and effort.
Scale insect
The insect body of the scale insect is wrapped in a layer of horny carapace. If it is sprayed directly with a drug, it is not effective. Like the blood-sucking scorpion, the scale insects absorb the sap of the plant and cause great damage to the flowers. The damaged plants not only grow poorly, but also yellowish leaves and early leaves.
Control method:
1. Use white wine for water at a ratio of 1:2. The surface layer of the potting soil is poured during the treatment of the insects. The scale insects begin to move at room temperature of 7 ° C in spring, and can be poured once in mid-April, and then poured once every half month or so for four consecutive times.
2. Using 50 ml of vinegar (rice vinegar), soak the small cotton ball in vinegar, and gently wipe it with the wet cotton ball on the stems and leaves of the affected flowers, and wipe off the scale insects. .
3. Use diesel oil, washing powder and water to adjust the mother liquor to the ratio of 10:0.6:6. At this time, the mother liquor is milky. After dilution with water, carefully spray the scale insects on Milan, kumquat and sago. A week later, most of the scale insects turned from fresh orange to dry.
