Description
Glyphosate plus 2.4D. Mixing the two increases the effectiveness of the medicine and speeds up weeding. But it also increases the risk of phytotoxicity caused by drift. Be careful when using it. Let’s look at the three pesticides: glyphosate, 2.4D, and mixed formulations respectively.
1. Glyphosate weed killer
Everyone is familiar with weed killer glyphosate, which is an organophosphorus weed killer herbicide. It has systemic conduction and broad-spectrum killing properties. It is a killing herbicide without any selectivity. Monocotyledons, dicotyledons, annual or biannual, grass or shrub, etc. As long as you are green vegetation, everything will be destroyed.
After green plants absorb glyphosate, it travels down the body to the roots. Root rot causes the plant to die. The time will be slower and it will take 3-5 days to take effect. If the temperature is low and the soil is dry, the dieback will be slower and longer.
In comparison, glyphosate’s herbicidal effect on broadleaf weeds is less effective.
2, 2.4-D weed killer
2.4D has dual nature. It can be used as a growth hormone at low concentration to promote the growth of crops. For example, use 5% 2.4D➕anti-falling agent➕gibberellin. It can be used to dip tomatoes into flowers to promote fruit setting. Slightly higher concentrations will cause deformation of crop fruits. Anything higher becomes a selective herbicide.
2.4-d is generally used to control annual broadleaf weeds in wheat fields, and is very sensitive to broadleaf crops such as cotton, rapeseed, sunflowers, melons, and beans.
3. Precautions for mixing
1. When applying pesticides, prevent the liquid from drifting to the young stems and leaves of citrus trees and nearby crop fields to avoid phytotoxicity.
2. In order to slow down the resistance of weeds, be careful to mix it with other pesticides.
3. Apply the pesticide on a sunny day with little or no wind and a temperature of 15-28℃. Use a standard sprayer to lower the nozzle or reduce pressure and pay attention to the wind direction when using it. When planting broadleaf crops within 100 meters or downwind, use mixtures with caution.
4. Grazing, mowing and plowing of land prohibite within 5 days after application.
In short, the combination of glyphosate and 2.4D is a very good formula. Under normal circumstances, blending (2%) will have little impact on crops and the residue period is not too long. However, if used excessively, the residue of 2.4-D butyl ester will cause distortion and poisoning in broadleaf crops.
