Although the glufosinate component has many advantages such as environmental protection, safety, and high efficiency, if the method is improperly used, the effect will be discounted, and it is likely that the expected effect will not be achieved. Then, how can farmers choose high-quality glufosinate products? How to use glufosinate properly and improve the use of drugs?
It is good to identify glufosinate
“But the correct method of use encounters poor quality products is no good.†The regional manager of Meizhou Branch of Zhongnong Lihua Guangdong Biotechnology Co., Ltd., who often makes product demonstrations in the field, mentioned that the product must choose a regular factory to guarantee quality. . However, the market for glufosinate is highly competitive, and many brands of common pesticide retail stores have appeared on the same stage. Then, how do the growers usually go to the farmer's store to choose glufosinate herbicides ?
Wu Huichao, manager of the agricultural wholesale department of Huihuan Supply and Marketing Co., Huizhou City, said that the good glufosinate preparation is clear and transparent, and it is easy to shake in the bottle, indicating that the preparation is relatively pure and contains less impurities. If the turbidity is unclear and is difficult to shake as in cooking oil, it means that the preparation has a high impurity content.
Lu Yizhen, manager of Huizhou District of Bayer CropScience (China) Co., Ltd., said that in general, pure glufosinate crystal powder is blue, but in the manufacturing process, a liquid with an active ingredient content of about 6% is produced. This liquid contains a lot of impurities, but it also has a herbicidal effect. Some manufacturers add this liquid to the glufosinate powder and distribute it as a 10% glufosinate water.
The content of glufosinate, which is labeled as 18%, 20%, 200 g/L, and 200 ml/L, is strictly the same, but the manufacturing process varies from one manufacturer to another. For example, it can be clearly seen that the water agent is transparent, and because of the addition of a special defoaming agent, the generation of bubbles is reduced during the preparation process, and the time from preparation to use is shortened.
Boshu Awen agricultural shop owner Yu Shuwen said that 10% glufosinate and 18% glufosinate have their own advantages. The former has the advantage that the herbicidal effect is faster. Usually, it can be effective in the afternoon, but due to the impurities, it is not excluded that some ingredients have a certain impact on crop growth. These impurity components vary depending on the process, and problems are difficult to rescue.
The higher purity glufosinate preparation usually only takes two or three days after the fight, but the effect period is longer. In general, the final herbicidal effect is similar, but the high purity glufosinate is safer for crops.
This is the best medicine
“Glufosinate is a contact herbicide that needs to be sprayed against green leaves to get the effect, unlike the systemic absorption of glyphosate.†Bayer CropScience (China) Co., Ltd. Guangdong District Technical Commissioner, the correct use needs to be Pay attention to the use time, spray spray and dose.
Huang Zengli reminded that some farmers use the turbid river water in the field when glufosinate is exchanged with water. This is easy to react and the passivation loses its efficacy. Secondly, there is no secondary dilution method for water exchange, which tends to cause uneven concentration and affect the effect. The glufosinate formulation should be diluted to a mother liquor with a small amount of water or a dilute carrier and then diluted to the desired concentration in a large container.
For the improvement of the utilization and efficacy of glufosinate, Huang Zengli recommends that when spraying glufosinate, it must be sprayed and sprayed uniformly, and it can be wetted with a nebulized sprayer. When spraying, it is important to note that glufosinate is not as strong as glyphosate, and it needs to be sprayed against the leaves. “Many growers spray quickly and do not spray on the leavesâ€. At the same time, additives such as silicone can be added to improve the permeability and spreadability, so that the surface of the weed leaves can fully contact and absorb the glufosinate to achieve a better herbicidal effect.
