How to prevent the treatment of beef tendon? Effectively killing the drug formula of goosegrass
Goosegrass is the grass that farmers are most disgusted with because it is difficult to control and kill. And the vitality is strong, as long as a little root can grow a large piece of grass, then what should I do? The following small series will share with you the reasons for the prevention and control of the tendon grass and the drug formula for killing the beef grass.
    First, why is it so difficult to control the beef tendon?
Goosegrass is a malignant weed of grasses. The reasons for difficult prevention and control are as follows:
    1, very adaptable
The tendon grass has strong adaptability to the growing environment, and the soil environment is not high, but the demand for light is relatively large. The fields, the roads on both sides, the wilderness and wasteland can grow wildly, and the growth ability is particularly tenacious. The southern part of the country is still in the north, and it has its place as long as there is soil.
    2, life is tenacious
The root system of the tendon grass is very developed, the root system is very large, and it is deeply rooted. Especially in the comparison of soil fertility and water absorption capacity, ordinary crops are not its opponents at all. It can directly plunder most of the nutrients in the field crops. Even the case where the tendon grass grows taller than the crop can be said to directly threaten the normal growth and production of crops.
    3, strong reproductive ability
The breeding ability of the tendon grass is very strong. It can be propagated by sexual reproduction (seed reproduction) and asexual reproduction (root, stem and leaf reproduction), which can spread grass damage extensively and widely.
    4, weed self-protection
Goosegrass is very self-protective. It belongs to a very strong weed that is very resistant. It is also very drought-resistant, and the surface of the tendon has a very thick waxy protective layer. After the conventional drug, the drug solution is difficult to adhere and penetrate into the leaves and the body of the plant of the tendon, which greatly reduces the efficacy and does not have a good anti-killing effect.
    5, the method of medication is not reasonable
The drug and time for the prevention and treatment of goosegrass are improperly used because it has strong vitality and belongs to the ill-to-treat grass, which is controlled by common conventional herbicide drugs. Many people can't catch the best prevention period of the tendon grass. When the weed grows up and grows again, it is difficult to kill it.
    6, drug resistance enhancement
The resistance of the tendon to the drug is constantly increasing. With the use of drugs for weeding by farmers for several years, the tendon has some resistance to the drug, especially the use of paraquat and glyphosate in the past. Herbicides, the tendon grass is self-protected, and the selective breeding of the goose is continued from generation to generation. The weeds that survive after the drug are more difficult to kill.
    Second, how to effectively prevent the killing of beef tendon?
    1. Physical weed control
Because the growth of the tendon grass requires a lot of light, the more used is to cover the mulch to inhibit the growth of the tendon grass, or to use the mulch and topsoil to smear the goosegrass in the high temperature. In addition, during the growth period of the tendon grass, the cultivating and weeding several times can also prevent the occurrence of the tendon grass.
    2, prevention and control during the best prevention period
When the beef tendon grows up, it is very resistant. It is difficult to kill with the medicine. Even if it is removed by hand, its root system is deeply rooted and deep, and it is difficult to pull. In drug weeding, the most effective time for the prevention and treatment of goosegrass is when the tendon grass grows to 3-4 leaves.
    3, the most effective drug formula
In the past few years, because of the large area and large amount of glyphosate, the effect of using glyphosate alone to kill goosegrass has been very poor. Therefore, everyone should switch to other more effective drugs or use drugs. Take control.
Here are five recommended mainstream drugs or formulas for the prevention and treatment of goosegrass: 1 cyanuric acid ester; 2 oxazolamide; 3 glyphosate + refined flucloxacil; 4 glufosinate + ketene ; 5 glufosinate + An Rongle additives.
Goosegrass is one of the many crop weeds, but it is the most difficult to control. If it is not timely, it will grab nutrients and nutrients with crops and hinder crop growth. The above is about the effective formulation of the drug formula for killing goosegrass. Learn from.
