Part I: List of red and rusty spiders to control the potions together
If there is no rust spider harm in the orchard in previous years, or no rust spider harm is found at present, then it is easier to spray medicine, choose 1 kind of medicine, then how to save money and do things well? That must be a choice of a red spider rust spider can be controlled by the potion:
【Rust Spider Medicine Statistics】
Butyrosyl Budweiser (stray worm, rusty spider)
Lice mites (rusty spider, leafminer moth)
Dimethyl pyridoxine (red spider, rust spider)

avermectin + ethosazole (eggs of red spiders, rust spiders)

Red spider agent is more, not easy to list, but the rust spider agent is less, the above listed some, can kill at least 2 kinds of insect pests / mites at the same time, you can choose according to their own orchard situation, choose the above potion is also more cost-effective.
If the orchard red spider is not serious, one of the potions worth mentioning is dimethyl aceta, which is a temperature-sensitive agent, the higher the temperature, the better, with its own internal suction mite (rare in acaricide). And the price is also relatively cost-effective, 45 yuan 1000-1500 pounds of water. One thing to note is that it is emulsion (dimethyl amygdine currently has no suspension agent, only emulsion), in the various forms of the drug, emulsion is the most lethal, but it is necessary to pay attention to the temperature, avoid using it above 30 ° C at noon, and try to spray in the morning and afternoon.
There is also a medicine that is also cheap and easy to use, that is, pyridoxine, if you feel that emulsion is not safe to use at high temperatures, you can also use this ingredient, which currently has a microemulsion dosage form, but the price is not so affordable.
In addition, in order to increase the rapid action of insecticide, mite killing, and killing pyllids and moth pests, the above agents can be combined with avermectin, an all-round drug. And the permeability of avermectin itself is relatively strong, which can strengthen the killing effect, and the prevention and control is widespread, and the basic medicine will be added. However, it is precisely because the permeability is too strong, so the dosage form of this ingredient emulsion is more likely to be harmful, and it is recommended that you use microemulsion.
This kind of orchard that has been harmed by rusty spiders in previous years, but don't worry about red spiders, the drug is the simplest, directly with lice mite urea + avermectin / butylc Budweiser on the line, want to be good, just add a lotto silicone additive.
Red spiders, rust spiders need to focus on prevention and control, the picture is from @my braised guitar
However, the orchard also has red spiders, and it is necessary to pay special attention to the control of rusty spiders in the orchard, it is recommended to mix 2 kinds of red spiders and rust spiders can be controlled by the potion. For example, use dimethylmidine + Avi. Spironyl ester/pyridine, Avi. Spironite ester + pyridoxine, or you can also use the first part of the drug alone with a lice mite urea + avermectin is OK. The specific choice depends on the resistance of the red spider, such as the use of biphenylhydrazine ester. Acetazole + acetalurea + avermectin, bimethoprim + pediculamide + avermectin and so on.
This is very flexible, generally red spiders are more serious, or focus on the prevention and control of red spiders are not cheap, so focus on resistance on the line. The most important thing can be added to a lotto additive, the synergistic effect is indeed unexpected, especially for canker disease, mites, this headache of pests and diseases, lotto has excellent spread, after the drug is not in the shape of water droplets, but covers the entire leaf, less gaps, better prevention and control.
