Herbicide plays a very important role in agricultural production, not only the herbicide efficiency is greatly improved, but also the herbicide effect is also very significant, the duration of efficacy is greatly prolonged, saving a lot of labor costs. There are many kinds of herbicides. At present, glyphosate has been used for the longest time in production and has become the most widely used herbicide.
Glyphosate is a chronic broad-spectrum herbicide, which can interfere with protein synthesis and lead to plant death. Glyphosate has become the most popular herbicide in the world due to its excellent herbicidal activity, wide herbicidal spectrum, low soil residue and long time of controlling grass. However, due to the large amount of single continuous use of glyphosate over a long period of time, the problem of weed resistance has become very prominent.
How can glyphosate resistance be addressed?
1.Crop rotation
Weed resistance is due to the large and frequent use of the same dosage form of glyphosate, and crop rotation can change the target enzyme of the herbicide, greatly reducing the occurrence of weed resistance.
2. Carefully apply drugs to improve prevention and elimination techniques.
It is an important step to improve the application of herbicide. There are still some phenomena of wrong application, misapplication, omission and indiscriminate application in production. Glyphosate is a broad-spectrum herbicide, not a panacea, not a panacea, that kills all weeds. Therefore, it is necessary to pay attention to the problems such as the application of herbs (different medicines are used in the old and young grass), rational control of drug dosage, cleaning of medicine equipment, and paying attention to climate and meteorology (temperature, humidity, wind direction, etc.).
3. Herbicide mixing and development of mixing agent.
The combined application of glyphosate and herbicide, such as acid drops, sulfonamides, imidazolinones, triazines and so on, can not only prolong the efficacy period of herbicide, but also solve the problem of difficult weed control and the cost of repeated application, and reduce the harm of weeds.
On the basis of cost, scientific research and technical level and effect, we focus on the research and development of compound preparation. The advantages of compound preparation are on the one hand to expand the weed control spectrum; On the other hand, it can increase the weeding effect and speed up the weeding speed of glyphosate.
Drop acid · glyphosate is a unique, now in the market recognition is more and more high, market share is also rising. Drop, acid glyphosate, make full use of the advantage of glyphosate and 2, 4 – drop acid compound with complementary, because glyphosate technical is used as the raw material, don’t use the “mother liquor”, thus no harmful heavy metals, inorganic salt, methanol and doesn’t make the soil harden and salinization, safe, friendly to environment is an environmental protection of new herbicides.
