The insect outbreak in spring is more serious, and the prevention method can be diluted with imidacloprid and carried out a comprehensive spray once a week or half a month to kill the eggs.

Sprinkle a little white medicine - dinotefuran on the surface of the soil as much as possible, which is particularly effective for oral pests, and the residue decomposition is fast, the toxicity is small, and it will not affect the growth of plants, which is a very good prevention and control drug!

Lemon trees, like most plants, may be infected with scale insects, red spiders and other small pests, once found, can be immediately treated with avi acetamiprid and other agents, generally 3-7 days in a row can be solved.

There are mainly anthracnose, scabs, gum flow, foot rot, macular disease, brown spot and so on. The main prevention and control methods are: strengthen cultivation management, pay attention to drainage and irrigation, increase organic fertilizer, and time felling and pruning to avoid orchard canopy.

Anthrax and brown spot are usually treated with carbendazim, 45% prochloraz, 80% zebsen zinc, 34% polyantimycin, etc., and scab and foot rot are usually cut off first, and then sprayed with 2% spring leimycin or 50% carbendazim for prevention and control.

Pests: mainly mites, bud maggots, scale insects, whiteflies, leaf miners.

Mites: artificial predator mites, orchard planting of thistle, etc. The agent uses lice caricature, 5% acetamiprid, 5% thiobenone, etc. for insecticide.

Flower bud maggot: according to the insect report, the adult unearthed when the ground spray, is the most effective way to prevent the flower bud maggot on the tree for damage, the use of the adult when the first time not to fly, first crawl on the ground of the favorable time, or in the bud (the bud is white like the size of a mung bean), or the bud is just white, the adult is fast to feather when the spray. 10% cyhalothrin and 5% avermectin can be used for insecticide per mu.

The prevention and control of red spiders should be adapted to local conditions, adhere to the principle of "prevention first, comprehensive control", and focus on chemical control, supplemented by physical control. At the same time, natural enemy resources should be fully utilized in order to obtain better control effects.

Strengthen cultivation management measures.

1) Increase the application of organic fertilizer, reduce the use of nitrogen fertilizer, enhance the tree strength, and improve the ability of plants to resist the invasion of pests.

2) In the high temperature and dry season, open holes and water in time to compensate for the water loss of plants.

3) Strengthen pruning, improve the microclimate of plant growth, enhance the ventilation and light transmittance of plants, improve tree potential, and reduce the chance of pests.

4) For the plants with serious occurrence of red spider in that year, scrape off the warped bark, remove the dead leaves, fallen leaves and weeds on the branches, eliminate the overwintering female adults and eggs, and reduce the number of insect sources.

5) For trees that are prone to mite damage, give the trunk bundle grass at the end of autumn to lure overwintering female mites, take down the bundle grass in early spring and burn it, remove weeds and fallen leaves in winter, and carry out centralized treatment to reduce the density of mites in the coming year.
