Aphids, also known in some places as honey worms or greasy worms, is a type of disease and pest that is most likely to appear in the process of planting and growing all kinds of crops in agricultural production, whether it is wheat, corn, rice and other field crops, or cotton, rapeseed and other cash crops, or tomatoes, cucumbers, apples, pears, peaches and other melon fruit and vegetable crops, will be deeply affected by aphids, aphids are small, fast reproduction, difficult to control, harmful, and aphids can also carry bacteria and poisons, resulting in the wide spread of various diseases such as virus diseases on crops.
After the sporadic disease of aphids on field crops, if you do not pay attention to the early prevention and early treatment of insect pests as soon as possible, crop planting should be strictly prevented and treated early to prevent aphids from multiplying and spreading in the field and causing greater harm.
In the control and management of aphids, most farmers and friends are only controlled by spraying insecticides after the occurrence of insect pests, and often cannot achieve more ideal control results, especially some weather environments that are not suitable for spraying, greenhouses, protected planting grounds, green melons, fruits and vegetables, etc., or some plots that grow flower pots or small areas of crops at home, and everyone will often feel more headaches in the prevention and control of aphids.
So, what are some simple, easy and effective ways to control aphids? If it is a protected planting site that cannot be medicated, or a large area of medicated planting, or a planting area that does not want to use drugs for control, what other methods can we use to control aphids? Today, the agricultural technology small back basket will summarize a variety of aphid control tips for everyone's reference.
<h1 class = "pgc-h-arrow-right" > first, the control method of physically killing aphids</h1>
1. Use a yellow armyworm plate to trap aphids
Aphids have a strong tendency to yellow color, we can take advantage of this physiological characteristics of aphids, by hanging a yellow armyworm board above the field crop 10-15 cm high or at the same level as the crop for booby-trapping, yellow sticky worm board can be self-made (you can first cut the thin plate to 20-25 cm X15-20 cm in size, first use yellow paint on both sides to paint yellow, and then apply a layer of waste oil or petroleum jelly on the board), you can also directly buy the finished sticky worm board, Yellow armyworm board per acre control 20-30 pieces (large board less, small plate more put), the armyworm board generally needs to be full of aphids or every 5-7 days to reapply the oil (or petroleum jelly), so that it can play the role of booby traps without spraying.
2. Use silver-gray reflective film to drive away aphids in the field
Aphids have a tendency to yellow, but have a tendency to avoid silver gray. Therefore, before the arrival of the high incidence of aphids or in the early stages of sporadic aphid disease, we drive away aphids in the field by laying a silver-gray reflective mulch film between the rows of the field, or hanging silver-gray plastic film between the fields during the growth period of the crop (Bijo Garden), or hanging (or covering) the silver-gray mulch/plastic film around the greenhouse, etc., in order to drive away aphids in the field and to expel aphids that want to migrate into the field.
3. Use black light to trap and kill aphids in the field
Black light is a kind of sharp tool used by our farmer friends in the field to trap insects, and we can also use it to trap aphids. In addition to the yellow tendency, aphids also have the characteristics of phototropism, so we can trap and kill aphids in the field by controlling black light in places where aphids are more dense and aphids are more active during the time period.
4. Use sweet and sour solution basins or aphid enticing agents to trap aphids
Aphids like to eat the sweet and tender juice in the young parts of the crop, such as new slights, young leaves, and young stems, which have strong sweetness, so we can trap aphids and heart-eating insects, borers, leaf curling moths and other pests by placing some homemade sweet and sour solution pots in the field. In the homemade method of sweet and sour solution pots, we can stir brown sugar (first boiled in hot water or boiled in a pot), vinegar, water, and white wine in the ratio of 1:4:1:16:1 to make a viscous liquid, and then placed evenly in the upwind direction of the field according to the amount of 10-20 pots per acre, or evenly suspended in the upper part of the canopy periphery in the orchard to trap aphids and other pests. This method can also be used for the control of aphids in household potted flower seedlings.
In order to improve the effect of booby-traping, you can also add a small amount of imidacloprid, acetamidine, prayadone and other insecticidal drugs in the sweet and sour solution.
In addition, you can also buy aphid sex attractants (such as aphid pheromones, etc.) on the market, and then dilute according to the instructions for use and hang in the appropriate position in the field to trap aphids, which is similar to the sweet and sour solution basin method.
5. Manual brushing to control aphids
Compared with other physical methods of controlling aphids, the control method of artificial brushing is more troublesome, so it is only suitable for orchard fruit trees with very dense insect populations, and it is also more suitable for family potted flower seedlings. In the fruit tree winter and spring dormancy period or spring flower pot growth period, if the tree trunk, branches, the number of aphids on the number is relatively large, at this time we can combine the winter shearing garden to use a brush to repeatedly brush, if the number of aphids on the flower pot is relatively large, you can use a brush dipped in water to clean up, and then clean up the aphids that are brushed down.
<h1 class = "pgc-h-arrow-right" > second, the use of natural enemies to kill aphids control methods</h1>
For all kinds of pests in the field, they have their own natural enemies, and these predators can directly catch pests for food. For aphids, there are more natural enemies that can prey on aphids, such as grass worms, small flower bugs, ladybugs, aphid wasps, bud cocoon bees, parasitic bees, red-eyed bees, bees, etc., so for crops that are not suitable or cannot be medicated, we can use the method of releasing or protecting these aphid predators in the field, so as to use natural enemies to catch and kill aphids in the field.
It should be noted that if the control method of killing aphids is used by natural enemies, it should be noted that the use of pesticides (especially high concentrations and highly toxic pesticides) is prohibited in the field for less than 15 days, otherwise the drug will directly kill all these natural enemies.
< h1 class = "pgc-h-arrow-right" > three, the use of irritating odor to drive away aphids</h1>
Aphids prefer the sweet and tender smell, but are more afraid of irritating temperatures, therefore, we can use the items commonly used in the family or easy to collect in life and simple treatment, so as to use the special temperature of these items to drive away aphids on field crops, but compared to large-scale crops, the following small methods are more suitable for use in potted flower seedlings or balcony vegetables planted in small areas of the family, generally sprayed continuously according to the control situation about 3 times, sprayed once every 3-5 days.
1. Pepper water to control aphids
Grind the pepper with a heavier spicy taste into chili powder or chop it into chili filaments, and then boil it in a pot for about 20 minutes according to the method of 1 pepper + 20 parts of water, wait for the water to boil and change color, cool and filter out the clear liquid, and then spray it on the crop or flower seedlings to play a role in preventing aphids.
2. Tobacco leaf water to control aphids
According to the ratio of tobacco leaves and water to 1:10, or according to the ratio of 1 kg of tobacco leaves + 10 kg of water, put it in a pot and boil until the water turns reddish brown, or soak it in a container for 1-2 days, and then filter out the clear liquid with 15 kg of water and spray it on crops or flower seedlings to play a role in preventing aphids.
3. Orange peel water to control aphids
The oranges eaten at home leave the skin, first dry and crush the orange peel into powder or tear it into small pieces, put the orange peel and water in a container in a 1:5 ratio and soak it for 1-2 days, and then filter out the solution and spray it on the crop or flower seedlings to play a role in controlling aphids.
4, garlic water to control aphids
The spicy garlic is mashed into a puree, and then evenly stirred according to the method of 1 part garlic puree + 1 part water, and then the filtration solution is sprayed with 30-50 kg of water according to the amount of water sprayed to the crop or flower seedlings to play a role in preventing aphids.
5. Wind oil essence to control aphids
Wind oil extract, which is commonly used in the home, can also play a role in the control of aphids. Dilute the wind oil essence with water in the ratio of 1:500-800, and then spray it on crops or flower seedlings to play a role in controlling aphids.
6. Salt and lime water to control aphids
The commonly used table salt at home is first melted with an equal amount of warm water (1 part of salt is used in 1 part of warm water), and then the quicklime is dissolved in accordance with the ratio of 1:4 with clean water, and then the salt water and lime water are stirred and mixed evenly, and finally the pellet is filtered out and then 4 times the water is evenly diluted and sprayed directly onto crops or flower seedlings, which can play a better aphid control effect.
< h1 class = "pgc-h-arrow-right" > third, grass and wood ash water control aphids</h1>
Grass and wood ash can not only play a role in adding potassium fertilizer, disinfection and sterilization for the growth of crops or flower seedlings, but also can be used to control aphids. The grass and wood ash and water are soaked continuously for 1-2 days in a ratio of 1:5, and then the filtration solution is sprayed on crops or flower seedlings to play a role in preventing aphids.
<h1 class = "pgc-h-arrow-right" > 4, urea water control aphids</h1>
Urea can be used not only as fertilizer, but also for the control of aphids. The urea, washing powder and water are stirred in accordance with the ratio of 1:1:100 to form a liquid, and the clear liquid is filtered out and sprayed on crops or flower seedlings to play a role in preventing aphids.
<h1 class = "pgc-h-arrow-right" > five, washing powder water, soapy water to control aphids</h1>
The washing powder or soap we usually use for washing clothes is also a good thing to prevent and control pests and diseases, not only can we add some medicine to the liquid to improve the efficacy of the medicine, but also can be used alone to kill insects.
If you use laundry detergent, you can dissolve the washing powder, soap (soap is first melted with hot water) and water into washing powder/soap in a ratio of about 1:60-100 times, and then spray it on crops or flower seedlings to play a role in preventing aphids. If you want to further improve the effect of prevention, you can also add a small amount of urea or diesel to the washing powder water or soapy water.
<h1 class = "pgc-h-arrow-right" >6, drug control aphid control method</h1>
1. Drug seeding control of aphids
You can use 60% imidacloprid suspension seed coating agent or 40% octylthion and other drugs, before sowing according to the weight of the seed for 0.2% of the drug uniform mixing, and then the seeds can be sown after 4-6 hours, you can control aphids, you can also control red spiders, gray planthoppers, whiteflies, golden needle worms, grubs and other pests.
2. Drug treatment of soil to control aphids
Before crop sowing or before colonization, you can use 5% imidacloprid granules or 5% thiazine granules and other drugs to kill the soil, under normal circumstances, if it is spread throughout the field, it can be used according to the dosage of 3-5 kg per mu, if it is applied in the ridge strip or ditch, it can be used according to the amount of 2-3 kg per mu, if it is used accurately in the colonization cave, it can be used according to the dosage of about 1 kg per mu.
3. Liquid medicine is irrigated to control aphids
When crop seedlings are colonized, 60% imidacloprid suspension seed coating agent of 2500 times per mu can be used in combination with watering planting water to irrigate and seal the soil, which can play a better aphid control effect.
4. Spray liquid medicine to control aphids
Drug spray control methods for aphids, more suitable for the use of aphids in the early stage of aphid disease or aphids in the field, commonly used drugs are mainly anti-aphid, acetamidine, imidacloprid, matrine, avermectin, cypermethrin, aphid pine, thiamethoxine, pyrazone and other drugs (there are many drugs available on the market), when using drugs to control aphids, you can use according to the type of drug and the content of active ingredients according to the instructions for use, generally according to the control of the situation of continuous spraying 2-3 times, every 7 days or so spray, If the aphid resistance is relatively strong, you can also add some silicones, laundry detergent, etc. to the liquid to improve the permeability and adhesion of the liquid, so as to improve the control effect of aphids.
In addition to the above methods, the agricultural technology small back basket in the end to remind everyone a little: aphids are small, fast reproduction, difficult to control, in order to effectively control aphids, although early prevention and early treatment of insect pests is very important, but by maintaining a reasonable planting density (not planting density too large), reasonable control of field humidity (not too diligent watering), to ensure that the crop ventilation and light transmission environment is excellent (whole branch, beating, leaf removal, pruning in time) and other fine field management, in order to effectively reduce the incidence of field aphids, Regardless of the aphid control method, it can only be used as an emergency remediation management after the occurrence of aphids.
