How to treat aphids? A full analysis of scientific control methods
How to treat aphids? What are some simple control methods for aphids? Experienced readers are also asked to help explain. Aphids are the most common pests, and they are also one of the most destructive pests in the world. Moreover, aphids have strong reproductive capacity, mainly because female aphids can reproduce as soon as they are born, and can reproduce 10 to 3... in a year.

Moreover, aphids have strong reproductive capacity, mainly because female aphids can reproduce as soon as they are born, and can reproduce 10 to 30 generations in a year. Therefore, Zhongdi Network has compiled aphid control methods, listed in detail below for readers' reference.
Aphid control methods:
Method 1: Use yellow sticky boards to trap and kill aphids:
Set up yellow boards at the edge of the field or in a greenhouse. The method is to use 0.33 sq m of plastic film, coat it golden yellow, then apply 1 layer of petroleum jelly or machine oil, and set up a frame at 0.5 m above the ground, which can trap and kill large numbers of winged aphids.

Method 2: Use natural enemies for control:
There are many kinds of natural enemies of aphids, such as ladybugs, lacewings, hoverflies, minute pirate bugs, aphid parasitoid wasps, aphid wasps and more than 80 other species. They can be introduced, bred or released. When there is a certain number of beneficial insects in the field, do not apply pesticides blindly. Aphid damage can be controlled by protecting the natural enemies of aphids, which is also advocated by the development of green and ecological agriculture.
Method 3: Use silver-gray plastic strips to repel aphids:
Because silver-gray has a strong repellent effect on aphids, silver-gray plastic strips can be hung in the garden or silver-gray plastic mulch can be laid to repel aphids. This method has a good effect on aphids migrating and spreading viruses.
Method 4: Use aphid sex pheromones to lure and kill them:
Drop aphid pheromone (400 milliliters) into a brown plastic bottle, hang the bottle in the garden, and place a water basin below it, so that the attracted aphids fall into the water and die.
Method 5: Use plant ash liquid to repel aphids:
Use 10 kg of plant ash, put it into 50 kg of clean water and soak for 24 hours, then filter it out. Add 25 grams of 80% trichlorfon crystal to the filtrate (or do not add it), mix well and spray, which can control aphids, cabbage caterpillars and other pests. Spray 1 time every 7-8 days, for 3 consecutive sprays, and the effect is good.
Method 6: Use seed coating agents to control aphids:
You can use 40% phoxim to dress seeds at 0.2% of the seed amount, or use 48% chlorpyrifos emulsifiable concentrate to dress seeds at 0.3% of the seed weight. After dressing, pile and cover for 4-6 hours, which can effectively control underground pests such as mole crickets, white grubs and wireworms, and also control red spiders, aphids, small brown planthoppers and others at the seedling stage.

Method 7: Use pesticides to control aphids:
It is recommended to choose pesticides with high efficiency, low toxicity and low residue, and to rotate and alternate multiple pesticides to delay the development of aphid resistance. For example, spray 10% imidacloprid wettable powder at 2000 times dilution for control; spray 1.8% abamectin at 3000 times dilution for control; spray 10% nicotine emulsifiable concentrate at 500-1000 times dilution for control; spray 50% pirimicarb wettable powder at 2500 times dilution for control.
