Who knows the specific control methods for sedge weeds?

If the next crop or the current season is not a vegetable, it is recommended to use sodium dimethyltetrachloride to remove sedge weeds.

Biology has learned to use insects to control weeds, mainly using insects to effectively control weeds, such as the lepidoptera moth family can feed on sedge weeds such as aconite, broken sedge, vitex triangular and water sedge. The newly hatched larvae can be bored into the tender heart by the heart leaves of A. aconite, causing the heart leaves to lose their green, and then bored into the bulbs, cutting off the conductive tissues, resulting in the death of the whole plant.

In the garden lawn, the main weeds of the sedge family are: fragrant aconite, water centipede, heteromorphic sedge, sunshine fluttering grass, water sedge, broken rice sedge, red scale flat sedge, cow hair grass, firefly, flat stalk grass, Japanese grass (Sanjiang grass), etc., and the fragrant aconite and water centipede are very difficult to prevent in lawn weeds. It prefers to be born on loose soil, and occurs more seriously in sandy soil, and is born in lawns, farmland, field edges, roadsides, wasteland, etc.

The seedling stage is from February to April, and the flowering and fruiting stage is from May to November. Tuber and seed propagation. The vitality and fecundity are very strong; Harder to eradicate.

Chemical control is mainly based on the characteristics of weeds, and chemical products are used for control. The benefits of chemical weeding: labor-saving, labor-saving, no damage to leaves, no damage to the lawn and no disease transmission, etc.

At present, there are many kinds of chemical herbicides on the market, but there are not many targeted ones. Cool-season lawn sedge control can use aconite digging or aconite net, and the effect is quite good. Despite this, you need to be careful when choosing a lawn herbicide so as not to damage the lawn, if the growth of the lawn is inhibited, you can apply Baneda Bika Gen Cong Cong + bacterial fertilizer to restore the growth.

The regional characteristics, lawn growth, climate and environment are different from place to place, and the performance of chemical weeding is also different. Read the instruction manual carefully and consult relevant experts. Try it in a small area first to avoid damaging the lawn and then use it on a large scale.

Cyperaceae weeds are a relatively common plant in life, so what are the common sedge weeds? 1. Heteromorphic sedge, generally distributed throughout the country, has a relatively soft texture, a multi-headed inflorescence at the top, relies on seeds to reproduce, and the suitable temperature for germination is between 30 and 40 degrees. 2. Fragrant aconite, which spreads relatively quickly, can germinate in the range of 13 degrees Celsius to 40 degrees Celsius, and is a malignant weed.

3. Firefly is distributed in the north and south of China, and when it is ripe, it is black-brown and shiny. 4. Flat-stalk grass is distributed in all parts of China, and can germinate in the range of 20 degrees Celsius to 30 degrees Celsius. 5. Broken rice sedge, the leaves are basal and arranged in a triangular shape.

The blades are narrow-stripped. It is distributed in most parts of the country, with strong cold tolerance and humidity tolerance, and is a moisture-loving weed, which grows rapidly in the rainy season.

1.Alleviate glyphosate drug damage Glyphosate has strong systemic conductivity, which seriously interferes with protein synthesis by inhibiting phosphate synthase in plants, resulting in pesticide damage to crops. The application of brassinin can accelerate the synthesis of amino acids in the body, make up for the amino acids lost due to pesticide damage, meet the needs of crop growth, thereby reducing pesticide damage until normal growth is restored, tillering is restarted, and young panicle differentiation is resumed.

2.Remove the herbicide of triamsulfuron residues, and triamsulfuron is an organic heterocyclic herbicide, which has a good killing effect on gramineous weeds and bibutyl cotyledonous weeds in rape fields. However, the daphene equilibrium sulfuron type is relatively stable and has a long residual effect period, which directly affects the planting of stubble-sensitive crops.

After the administration of brassin, through the co-ordination.

Thiophenesulfuron + quinoxalin.

1) Cyperaceae plants have a strong resistance to thiensulfuron and quinoxalin (almost no pesticide damage).

2) The two are mixed with Hekuo double division. Thiophenesulfuron to remove broad-leaved weeds, and quinoxalin to remove grasses weeds.

Shakodan can be used to prevent and remove Ze Yuan, lotus seed weed, duck plant, Baishui eight-yard chain horn, Cigu, Mo Shangcai, Yujiuhua, duck tongue grass, knotweed, dwarf Cigu, pointed petal flower, Tian Jing, cow hair felt, water sedge, special-shaped sedge, broken rice sedge, firefly, vitex three ridges, spicy grass, flat stalk grass, Japanese scallion, oil sedge, snakehead sausage, flat spike sedge, etc.

Usage: Apply pesticides at the end of rice tillering to before jointing, use 133 167 ml of 46% Shakodan (active ingredient 61 77 grams) per 667 m2, and spray 15 40 liters. When spraying, the height of the nozzle, the pressure and the walking speed should be fixed to achieve uniform spraying.

When the ant grinds and sprays, it cannot be sprayed left and right, and it cannot be sprayed repeatedly when the density of sedge weeds is large.
