If you want to plant in summer and winter, you must have a good temperature control.

In order to promote a higher germination rate of lavender seeds, it is recommended to promote germination treatment before planting. Soak its seeds in clean water first, and then take them out and put them on wet wipes after a day or two, and cover them with a thin layer of freshness, and poke a few holes on them to ventilate. After processing, put it in a cool, warm environment to promote germination, and wait for white roots to grow before sowing.

If you don't deliberately promote germination, it may take more than a month to germinate when planted directly.

Lavender pests and diseases are prone to occur in the middle of July every summer. That's when you have to manage them well. If you manage them well, the incidence of lavender pests and diseases will decrease.

So what kind of pests and diseases does lavender cause? Are there any ways to control pests and diseases? Here is a brief introduction to the two types of pests that can occur on lavender, mainly red spiders and aphids.

Introduction to lavender pests and diseases.

Lavender's red spider is a type of mite. It mainly damages the leaves, makes them lose their vitality, and presents yellow rust spots, which can not carry out normal photosynthesis, which will seriously hinder the flowering and heading of the entire lavender garden.

The following methods can be used to control spider mites:

After cutting flowers in early July every year, the whole garden is sprayed with avermectin 3000 times once. Be careful when spraying and spray on the back of the leaves. Spray again every 10 days to achieve a good control effect.

Hazards of aphids and control methods:

In summer and autumn, especially after cutting flowers in July, swarms of aphids gather on some lavender plants. These aphids eat the leaves of lavender, hindering the healthy growth of the plant. In the middle and upper part of July, the whole garden was sprayed with 800-1000 times of 40% dimethoate emulsifiable concentrate once.

It can achieve a very good control effect.

Lavender leaf spot The symptoms of annual seeded seedlings and cuttings are wilting, dehydration, dull color, crooked branches, and in severe cases, the roots are wilted and rotten, and the stem ducts turn brown. In addition to the above symptoms, seedlings that are more than three years old also have wilting symptoms, which expand from the inside to the outside in the center or edge of the plant, and the branches wilt and die until the whole plant dies.

The main prevention and control methods are to spray Bordeaux liquid 1:200 to prevent 2 3 times, or 500 800 times of zebze.

Lavender root rot Because the lavender seedlings do not return to spring in spring or do not return to spring well, dry up and die, or can return to spring normally in spring, but in the early flowering of the bouquet wilted, continue to drop flowers until all fall off, the diseased plant autopsy can find a large number of vascular necrosis of the rhizome.

There are many ways to prevent this kind of disease, mainly choosing the soil with flat terrain and good drainage and irrigation conditions; When planting seedlings, the seedling shoots of disease-free fields were collected and treated with methyl tobuzin or carbendazim; application of organic fertilizer; Pay attention to the pruning of old branches and diseased branches; Prepare before wintering, bury the soil tightly and evenly; The most important control method is foliar spray with 400 times of 70% methyl tobuzin wettable powder or 500 times of carbendazim wettable powder.

Its prevention and control methods mainly include timely treatment of litter and leaf litter, cleaning up the environment to destroy the living place of leaf mites; correct tillage methods, reasonable crop rotation, and strengthened water and fertilizer management; Protect natural enemies, release natural enemies, and treat insects with insects. In addition, there are prevention and control methods: in the early stage of the disease, spray evenly with matrine 1000 times, and when it occurs in a large area, spray evenly with 20% dicofol EC 1000 2000 times, or avermectin EC 3000 4000 times, and the control effect is better.

The main control method is to use 50% phosphine EC, 50% pine borer EC, 12% crown insecticide EC and other pyrethroid agents.
