Aphids, red spiders, and scale insects are the most common types of sucking pests that damage flowers and trees. They are a variety of flowers and trees, whether it is woody flowers such as Milan, jasmine, rose, smiling, plum, or herbal flowers chrysanthemum, geranium, pouch, etc., are not spared.
After years of exploration and experimentation, the author adopts the following simple and effective methods of killing, which not only facilitates the materials, but also does not pollute the environment.
Aphid mites, also known as armyworms, occur all year round, generally at temperatures around 29 °C, and the fastest reproduction. There are many types of mites, usually green, yellow, black, and brown. It is a flower that affects the rose, pomegranate, chrysanthemum, and medlar. They are more concentrated on the buds, young leaves or twigs of the plants, sucking the juice without stopping, causing damage to the buds and petals. The branches and leaves of the damaged plants are yellow and deformed, the tidbits are damaged, the flowering period is shortened, and the flower color is reduced. In severe cases, the plants will die and die. The methods of prevention and treatment are:
(1) Use 50 grams of fresh or dried red pepper, add 30 grams to 50 grams of water, cook for about half an hour, and use the filtrate to sprinkle the affected plants with special effects.
(2) Using detergent powder 3g-4g, adding water 100g, stirring into a solution, continuous spraying 2 times -3 times, the control effect reaches 100%.
(3) Add 600 times to 800 times the solution with “Feng Jing Jing†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.
(4) The washing powder, urea, and water are stirred into a mixed solution at a ratio of 1:4:100 to spray the plants. You can receive the effect of pest control and fertilization.
Red spider red spider, also known as short-stalked dragonfly, is a pest specially designed to damage flower leaves and flowers. The wild cockroaches, the plums, and the five needles in the bonsai are also vulnerable to the red spider.
The spider's body is like the tip of a needle, deep red or purple, and only the red dots are visible to the naked eye. Under the magnifying glass, the orange-red transparent spherical eggs can be seen. Its nymphs often cluster on the backs and buds of some flowers.
The sap-sucking mouth sucks the juice and damages the plant. The leaves are chlorotic and the leaf edges are rolled up, causing scorch and shedding, resulting in early atrophy of the flower buds and death of the plants in severe cases.
Red spiders occur 7-8 generations a year, starting from March to April each year, and severely from June to July. After the end of April, the plants should be observed and checked frequently. In the case of high temperature, high humidity and poor ventilation, the red spiders breed very fast, which is one of the important causes of plant death. The prevention method is:
(1) Soak the citrus peel with water for about 10 times for a day and night, spray and spray the plants to control aphids and red spiders. For example, watering flowers can control the nematodes in the soil.
(2) 15 grams of washing powder, 15% of caustic soda (NaOH), 15 ml of water, 7.5 kg of water, and the three are mixed and sprayed. After one or two days, the mortality of the spider mites and nymphs is 94%-98%. .
(3) Take 50 grams of grass ash, add 2500 grams of water, stir well, soak for two nights and nights, add 3 grams of washing powder and mix thoroughly, then spray once a day for three consecutive days, then spray for three days every other week to eliminate the second generation of pests. It can also control sucking pests such as aphids, red spiders and scale insects, and can be used to control aphids in the soil.
(4) Ignite a mosquito coil, put it in the pot of the diseased plant, and then use a plastic bag to even tighten the pot. After an hour or so of smoke, it can be killed by egg or adult. This is both saving and quick. A good way.
The insect body of the scale insect is wrapped in a layer of horny carapace. If it is sprayed directly with drugs, it is not effective. Like the blood-sucking scorpion, it absorbs the juice of the plant, which causes great damage to the flowers and trees. The damaged plants not only grow badly, but also yellowish leaves and early leaves, which can cause the plants to wither and die. The flowers that are affected are Milan, Moss, Camellia, and laughter. The methods of prevention and treatment are:
(1) Use white wine to water in 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 the spring. It can be poured once in April, and then poured once every half month, for 4 consecutive times.
(2) Using 50 ml of vinegar (rice vinegar), soak the small cotton ball in vinegar, and gently rub it with the wet cotton ball on the stems and leaves of the affected flowers, and then kill the shellworm. Off. This method is convenient and safe, and can achieve the purpose of removing insects, and can make the damaged leaves return to green and bright.
(3) Using the alcohol to gently rub the diseased plant repeatedly, the scale insects can be removed, and the scale can be removed very cleanly. Not only can the scale insects be removed, but the larvae that are invisible to the naked eye are also completely killed. In the second year, it is rarely found that the scale insects are harmful. This method is simple, safe and effective.
(4) Adjust the mother liquor with diesel oil, washing powder and water at a ratio of 10:0.6:6. At this time, the mother liquor contains 60%, which is milky. After diluting the oil containing 30% with water, it is applied to Milan, kumquat and sago. The scale insects are carefully sprayed. After one week, most of the scale insects changed from fresh orange to dry state, indicating that this method has a good control effect on scale insects.
