At present, orchard citrus lice, nymphs, eggs mixed occurrence, the occurrence period is the peak period to the peak period, the field generation overlap is serious, the reproduction speed is fast, the amount of insects grows rapidly, which poses a serious threat to the development of the citrus industry, and many orchards are seriously yellowed and cannot be put into production.
Why are psyllid outbreaks so severe?
In recent years, with the downturn in citrus prices, the phenomenon of abandoned gardens and unmanaged gardens has been seen everywhere, which has aggravated the incidence of diseases and insect pests. The migration of psyllids is very strong, not only abandoning their own orchards, but also affecting the surrounding fruit trees, aggravating the harm of psyllids. Some orchards are not well managed, missing the best time to spray medicine, which is easy to cause a large outbreak of pests and diseases.
Why are psyllids so difficult to prevent?
Because citrus psyllids often overlap generations, adults, nymphs, and eggs symbiotically, making it difficult to control them. At the same time, the wood lice are very migratory, and a dozen pills may fly away, and it is difficult for the potion to touch it.

Wood lice have yellowing, like to harm the young shoots, young leaves, when the new shoots are ready to emerge or just emerge to spray, the new shoots come out 1 to 3cm, hit a potion; after 7 to 10 days after another dose of medicine, until the new shoots are ripe. Recommended agents: imidacloprid, thiamethoxine, nicotinyl, ethyl spironoid, cypermethrin, acetamidine, etc., pay attention to the rotation of agents.
If the occurrence of wood lice is more serious, it is necessary to mix the two agents to achieve the ideal effect. Such as: cyanide bromide imidacloprid, thiamethia perchlorofluoride, cyanidine cyanopyridine and the like.
2, the migration of wood lice is very strong, the efficiency of the whole orchard is higher, do not drag for a few days to finish the medicine. Not only do their own orchards prevent the psyllids, but they also call on the surrounding orchards to prevent it together, and only by working together can we prevent it.
