There are many diseases and pests of fungus, how to prevent and control the diseases and pests of fu

Brown spot disease. Also known as purple spot disease, fish eye disease, red spot disease, it is a bacterial disease that can occur from seedlings to the end of harvest, mainly harming leaves. Ear cabbage sunflower.

It is a fleshy herb wound in the Larch family, because of its seedlings, young leaves or young leaves are edible, the leaves are like fungus, the texture is smooth and smooth with the fungus, making soup, making cold dressing, and with a fragrance, many do not know the scientific name of fungus vegetables or tofu vegetables.

Brown spot disease is mainly dangerous leaves, the affected leaves have small water-red water-stained dots at the beginning, and then gradually spread, turning gray-white to brown in the middle, dark brown, thinner but not easy to perforate. In severe cases, it will cause premature leaf withering.

For the damage of leaves, the lesions are nearly round, the size of sorghum grains to soybean grains varies, the edges are purple-brown, and the boundaries are clear; The middle part of the lesion is yellowish-white to yellowish-brown, slightly sunken and thin, some are easy to perforate, and in severe cases, the whole leaf is covered with lesions, losing its edible value. Brown spot disease is harmful to the leaves of agaric vegetables, and can be sprayed with zeb zinc wettable powder and grubs.

Mainly harmful to seedlings, phosphine can be used at the time of sowing.

Stir in the soil. <>

Fungus dish, there is a famous tofu dish in my hometown. Generally, seedlings or leaves are often eaten as vegetables, the texture is very soft and smooth, and can be made into soup dishes or stir-fried or cold dressing, and it tastes like eating fungus. In our south, there are cultivated and there are wild ones.

Brown spot disease, also known as purple spot disease, fish eye disease, and red spot disease, is a bacterial disease that can occur from seedlings to the end of harvest, mainly harming leaves.

Trichoderma: Trichoderma green and Trichoderma consoni, etc. Trichoderma hyphae.

The initial stage of the body is white. Gradually turn light green. Finally, it turns dark green.

Trichoderma is very easy to occur when the pH value is acidic, coupled with poor ventilation, high humidity and high temperature. The toxin secreted by Trichoderma kills the mycelium of black fungus. In the production process of black fungus, there are often miscellaneous bacteria and pests and diseases.

Affect the production and quality of black fungus, especially in the high temperature and suitable temperature season, the occurrence and harm of pests and diseases are the great enemy in the cultivation of black fungus, so the prevention and control of pests and diseases is very important.

Appropriate dense planting, 1 meter wide furrow strip sowing or 5 rows, plant spacing 20 cm. Ecological prevention and control should be adopted in the protected area, timely ventilation and humidity reduction, and excessive watering or partial application of nitrogen fertilizer should be avoided. After picking, top dressing should be carried out in time, and foliar spraying of yield-increasing bacteria and phytoprophine can promote early growth and rapid development of plants and improve yield.

First of all, when planting, we must choose the soil is more fertile and broad land, and in the process of fertilization, we must choose farmhouse fertilizer, do not use the fertilizer bought outside, but also often water more, to prevent the occurrence of pests and diseases, if there is a situation of small insects, then we must spray insecticides in time.

It is still preventable to prevent and control fungus vegetables in advance, choose a fungus vegetable that will not grow this disease, and find a way to plant it in batches.

This is the case, use the detoxification leaf to spread the suspension fertilizer, spray three times the best is that the effect is immediate.

Some pesticides should be used to prevent pests and diseases, and they should be watered frequently, weededed, exposed to sunlight, and regular pruning of branches and leaves.

This condition is mainly manifested as brown spot disease. The diseased leaves will form round lesions, the size of soybean grains, with purplish-brown edges. Eventually, it will also allow the entire leaf to rot.

There will be a lot of deformities in the leaves, and at the same time, there will be chloasma, the leaves will turn yellow, the whole of the fungus will be particularly wilted, and the color of the fungus will also turn yellow.

The leaves are very mottled and bulging in some places, and the leaf surface becomes uneven.

Try to choose some anti-insect and sterilization drugs, so that they can be effectively removed, and at the same time, the temperature should be increased, and try to put it in a place without sunlight.

The first is to select varieties with strong resistance to diseases and pests, the second is to spray drugs to prevent and control, the third is to apply fertilizer reasonably, the fourth is to water reasonably, and the fifth is to strengthen field management.

To clean the vegetable garden, and remember to spray pesticides, observe the growth of fungus every day, usually pay attention to the weather and temperature changes, and choose high-quality fungus roots and seedlings when planting.

In the early stage of planting, the land will be sprayed with some pesticides, or when planting, you can also control the density between them, the planting distance is controlled at about 10 cm, to receive sunlight, to spray some pesticides appropriately, and where the growth is more lush, you can prune it.

The main pests that harm the fungus are pseudo-Kaiqi walking insects, nematodes, ants, thrips, etc., and some pests in the side or bite the ear piece, or bite the mycelium, or eat the ear wood, causing harm. In addition, there are slugs, inchworms, small spiders, longhorn beetles, gidding insects and other pests that harm ear wood.
