Spray on the radial leaf surface of the plant and try to spray evenly. Root irrigation: Add 800-1000 ml of water to each liquid: After dilution, irrigate along the roots and increase or decrease the number of times depending on the situation. It usually takes effect in 2 hours.

Garlic oil can be used with insecticides. Garlic oil is an insecticide and fungicide auxiliary, which can kill bacteria and double the effect of insecticides. It can also repel red spiders. Liang Guoan is particularly effective in killing moss with garlic oil.

3. What medicine is most effective in preventing and controlling red spider mites?

For chemical control of red spider mites, apply 4000-5000 times of Dicypermethrin (each bottle of 100 ml is diluted with 800-1000 kilograms of water) for even spraying, 1000-1500 times of 40% dicofol emulsifiable concentrate, 2000 times of 20% Dicypermethrin wettable powder, 2000 times of 15% Dapoxetine emulsifiable concentrate, 6000-8000 times of 1.8% Amitraz emulsifiable concentrate, etc. to achieve the ideal control effect.

What medicine is most effective for spider mites? Experts strongly recommend it. It is easy to use and saves money.

4. What medicine is effective for wheat red spider mites?

Red Spider

When wheat enters the greening period, the dry and rainless climate conditions are favorable for the occurrence of red spider mites. Ineffective prevention and control will cause yellow-white spots on wheat leaves. After the red spider mites suck the nutrients in the leaves, the wheat will grow poorly and the plant development will be hindered. In the event of a large outbreak, the seedlings will dry up and die. Therefore, if the weather is dry during the greening period, monitoring should be strengthened. If the number of mites reaches 200 at a length of 33 cm, or there are 6 mites per plant, pesticide control should be carried out in time. 18% avermectin emulsifiable concentrate, 15% pyridamole emulsifiable concentrate, 40% omethoate and other sprays can be used for prevention and control. In addition, wheat red spider mites have the habit of falling to the ground when frightened. The insect bodies can be shaken off by watering the wheat fields, and the mites can be silted and drowned by irrigation to reduce their occurrence.

5. What is the best red spider medicine to buy for strawberries?

Natural enemy control

In the early stage of red spider mite outbreaks, natural enemies are used to control the population, and predatory mites are released during the flowering to fruiting period.

Try to reduce the number of red spider mites as much as possible before releasing predatory mites, use 1% matrine·azadirachtin or 10% avermectin water-dispersible granules for pest control, and release predatory mites 5 to 10 days after medication at a benefit-harm ratio of 1:10 to 1:30.

One predatory mite can prey on 300 to 500 red spider mites in its lifetime, and it also sucks the eggs of harmful mites, which can effectively control the damage caused by red spider mites.

Chemical control

Plants with red spider mites should be sprayed with chemical pesticides separately to ensure that the source of the insects is eliminated while blocking the spread of the insects to other plants.

Effective agents include: bifenazate + etoxazole, thiamethoxam, abamectin emulsifiable concentrate, and propargite, which can be used alternately.

If red spider mites occur over a large area, biological pesticides can be used for control 2 weeks before the strawberries mature, such as 800 times diluted 6.5% emamectin benzoate saline dispersible granules, 500 times diluted 0.5% matrine emulsifiable concentrate, and 300 times diluted 1.3% azadirachtin aqueous solution.

Precautions

● When spraying pesticides, be sure to use a gasoline engine or high-pressure spray, blow the leaves over, and make sure the pesticide is sprayed on the back of the leaves.

● When applying pesticides, the amount and speed of application must be strictly controlled to ensure uniformity, and no areas are missed or sprayed twice.
