In the winter, it is a high season for outbreaks of balcony potted insects. How to control these pests scientifically and effectively? Listen to what the bots say.
How can you get rid of the "black fly"?
The pots in your home always have an endless stream of nasty little black fly. They fly everywhere, and even fly into your bowls and cups... How can you get rid of these annoying little blacks? Fly?
Let us first understand the so-called "black fly" and its growth habits. The scientific name of the "black fly" is the sharp-spotted mosquito, which is often produced in moist soil and feeds on the surface of unfermented organic matter. The main developmental stages of S. obliquus are divided into egg-larvae-cockroaches-adults, and the reproduction speed is particularly fast. The larvae feed on the fungus algae in the soil in early stages, and bite the flower roots later in the larvae, although the bite to the flowers The resulting damage is not great, but it can carry germs, nematodes, and ticks. After its bite, the damage caused by flowers and grasses can be great!
Although there are many types of drugs used to prevent and treat S. obliquus, they are particularly smart. When spraying drugs, they will fly far away and hide. When the medicine fails, it will fly again. Back, so repeated, it is difficult to cure. Therefore, the prevention and treatment of S. obliquus must start from the source.
â– Soil disinfection
Do not hurry to use the flowers once they are bought back. It is best to disinfect first to kill the eggs inside. The following two simple methods of household soil disinfection can be used:
â—† Daylight disinfection method will evenly spread the soil in a clean container or on the ground. The soil should be as thin as possible. After exposure for 1 week (in the summer), 2 weeks or more (in the fall), you can kill a large amount of pathogen spores. , hyphae, pests and pest eggs and nematodes. For the returned organic fertilizer, this treatment can also be done.
â—† High-temperature disinfection method 1 Put the soil in an idle steamer, continue boiling for half an hour to one hour after steaming, and use high-temperature steam to disinfect it; 2 Place the soil in an idle wok and stir fry hot. In half an hour, use high temperature to disinfect; 3 Put the soil in a black plastic bag, spray the water in a damp state, and then expose it to sunlight for more than two weeks. During several times, turn and spray several times. It is also the same. Disinfect with high temperature steam. The above method can basically kill all pathogenic organisms, including the sharp-spotting mosquitoes at various stages of growth.
â– Management measures
◆ Watering the flowers Watering the flowers is best to adhere to the principle of “see dry see wet†and avoid frequent watering. On the one hand, it is easy to cause the roots of the flowers to rot; on the other hand, the wet basin soil provides the growth of the sharp-spotted mosquito. A suitable hotbed.
â—†Besides using regular liquid or solid fertilizer, do not pour unleached litter and kitchen waste (including tea water, rice water, peel, leaves, milk, etc.) into the flower pot. Sharp-eyed galls provide tasty food.
â—† Ventilation and ventilation also have a certain effect on the prevention and control of sharp-spotting mosquitoes. In the season when the temperature is appropriate, the window can be used to blow off the sharp-spotted mosquitoes by wind, and even blow dry.
â– Control methods
â—† The yellow armyworm board has a tendency of yellowing due to the sharp eyed gnat mosquitoes. Therefore, the yellow armyworm board can be suspended above the flower pot for a long time. Once a small amount of sharp eyed gnat mosquitoes are generated, it will be attracted by the yellow board and then be stuck. death.
â—† Chemical control can choose biological pesticides with lower toxicity, such as: pyrethrin, rotenone and so on. Chemical pesticides, such as pyrethroid insecticides, can also be selected for spray control, and mosquito repellents sold in supermarkets can also be used. No matter which medicine you choose, you need to put the potted plants on the balcony for 2-3 hours after using the medicine to avoid harm to the human body. When using pesticides, use according to dosage, wear protective clothing, pay attention to medication safety.
Hate red spider mites are effective
In winter, the high temperature and dryness of the heating room provided favorable conditions for the production of red spiders, causing them to invade. When you plant flowers and grow vegetables on the balcony, you must be prepared. Once you find the trail of red spider, you should prevent and treat it as soon as possible so as not to cause more damage to your potted plants.
However, since most people do not recognize the little red spider, once the potted plants are found to be “sickâ€, red spiders often have a large area and the losses are serious and difficult to control. So, how can we identify early in the occurrence of red spiders?
The red spiders are mainly two-leafhoppers and cinnabar. The adult females of the two-spotted spider mites are dark red, with black spots and ovals on both sides of the body. Overwintering eggs are red, and non-overwintering eggs are less yellowish. Overwinterlings are young, red, and non-wintery. If the wintering dynasty is red, if it is not overwintering, it will have yellow spots on both sides of the body. Adults, juveniles, and ruminants suck sap on the back of the leaves and form a net. At the beginning of the damage, sporadic chlorotic spots appeared on the leaves. At the late stage of damage, the leaves were covered with white dots and the leaves scorch and fall off, causing premature aging of the plants. There is a tendency to damage the lower leaves first and then spread upward. High temperatures and droughts are most conducive to the occurrence of red spiders, and long-term high-humidity conditions are difficult to survive.
So why is Starscream repeated? The original Starscream can be carried by insects, birds and animals, humans and animals, wind power, running water, agricultural tools and flower seedlings. Even if your balcony has been cleanly cleaned, if you buy a potted plant from the outside (this flower has infected red spiders) or you borrowed a neighbor's farm tool (used on the plant of the red spider), even When you open the window, the red spider on the balcony of your neighbor will ride in the wind to “flyâ€. At this time, as long as your home’s balcony conditions are right, it will begin to multiply.
The key question is, how do we prevent and treat the odious red spider?
â—†Physical control Use clean tools to remove weeds from pots in a timely manner, destroy old lower leaves, insects and leaves in time, and bring them to the outside for centralized destruction. Newly purchased flowers from the market must be clearly inspected to reduce the source of insects.
â—† Biological Control If a small amount of red spiders are found, the population of red spiders can be controlled by natural enemies in the early stage of occurrence. The balcony pots can release 50 to 150 heads per square meter of Bardock blister, or 3 heads to 6 heads of Chilean vegetative plants. / square meter.
â—†Chemical control If the above method does not work, it can be used in the initial stage of the use of pesticides diphenoxylate (aika) spray control, and in accordance with the dose. After using the medicine, put the potted plants on the balcony for 2-3 hours to avoid any harm to the human body. When using pesticides, wear protective clothing and pay attention to medication safety.
Insect pests to mess it up to eliminate it
In the heating room in the winter, most afraid of insects (worms) to mess. Although they are small, they are not small at all. They not only wrinkle the leaves but also spread a variety of diseases and insect pests. How can these insects be destroyed?
â– Know the locust
â—† Assassins, also known as worms, are a group of herbivorous insects, including all members of the genus Acridoidea. Up to now, about 4,400 species of 10 families have been discovered, of which approximately 250 are serious pests that have caused serious damage to agro-forestry and horticulture.
â—† Morphological worms are divided into two types, winged and wingless, ranging from 1 mm to 10 mm in length and translucent. For the body color of aphids, many people will be confused because most people think that the locusts are green, so black-winged crickets are often confused with black-winged crickets. In fact, the locusts have a lot of body color, such as black, white, yellow or even orange, and our common locusts are mostly yellow-green or black. In addition, wingless worms also produce winged worms in harsh environments.
â—† Insect pests, which are pest-inducing mouthparts, are often clustered on young leaves, tender stems, and buds of flowers and vegetables. They rely on the sap of sucking plants to cause the leaves to shrink and curl, and when severe Causes the whole plant of flowers and vegetables to wither or even die. In addition, the sticky honeydew secreted by aphids lands on the leaves, attracts a large number of ants, induces coal contamination, and spreads viral diseases.
â– Locust origin
Planting flowers and vegetables on the terrace, as long as the temperature is appropriate, locusts can occur throughout the year. Among them, the most suitable aphid breeding is in the conditions of 16°C-22°C and drought conditions. In addition, excessive planting density is also conducive to the occurrence of aphids. For open-air pot plants, when the temperature drops in the fall, the locusts will migrate to the wintering host to lay eggs for the winter. When the temperature in spring rises, the locust eggs hatch and multiply, and some locusts move to other host flowers or vegetables.
â– Control methods
â—† Biological predators Harmonia axyridis is a good helper to control aphids. The Harmonia axyridis is an insect whose body is hemispherical and has various types of colors and markings on the back. All growth stages of the Harmonia axyridis are characterized by the eggs of aphids, scale insects, wood lice, and lepidopterans. And the small larvae eat, so it is called "super killer", especially its adult, an average of 60 days to eat about 60 aphids. Therefore, you can choose to buy ladybug eggs to control aphids.
â—†Physical prevention and control In the autumn, we must promptly clear the litter in potted plants in order to eliminate the habitats of locusts. In the spring, when changing the pots and sowing vegetables, it is best to sterilize the soil (disinfection method is the same as “black flyâ€). Soil disinfection in order to eliminate aphid eggs. In addition, yellow sticky traps can be hung around the pots to trap insects.
â—†Chemical control can choose biological pesticides with lower toxicity, such as: pyrethrin, rotenone, etc., and also can choose chemical pesticides, such as: pymetrozine, imidacloprid, thiamethoxam and other insecticides for spray control. No matter which medicine you choose, you need to put the potted plants on the balcony for 2-3 hours after using the medicine to avoid harm to the human body. When using pesticides, use according to dosage, wear protective clothing, pay attention to medication safety.
