The 41% glyphosate isopropylamine salt solution is a broad-spectrum systemic herbicide that is highly conductive, absorbed by the green parts of the weeds, transmitted to the whole plant, and hinders the photosynthesis of the plants leading to death. The main control of monocotyledonous weeds in one or two years, especially the underground tissue of perennial deep root weeds is extremely destructive. Let 's take a look at how to use this herbicide to achieve good efficacy with the China Pesticide Network .
PVC Coated Wire, Common colors available
for PVC coated wire are green and black. Other colors also available on
request.
PVC Coated Wire Application: The most
popular use for PVC coated wire is in the construction of chain link fences for
industrial security fences, freeways and tennis courts. It is also used in
other applications such as coat hangers and handles.
Packing:
1. lined with P.V.C strips and wrapped with
PVC or hessian cloth

Although the 41% glyphosate isopropylamine salt solution is a conventional product, it is noted that the following five aspects can achieve better efficacy.
First, the spray nozzle has a small aperture. 41% glyphosate isopropylamine saline solution sprayed into a fine mist, the best herbicidal effect, therefore, the use of 0.8mm aperture nozzle is better than the commonly used 1.0mm aperture nozzle, while paying attention to prevent the liquid with the wind Drift causes crop damage.
Second, it should be applied after the rain in summer and autumn, sunny afternoon or cloudy. When the temperature of the air and soil is suitable and the humidity is too large, the growth and metabolism of weeds is fast, and the herbicidal effect is best at this time. It is not advisable to apply medicine during the drought period, before the rain and under the hot sun.
Third, the elimination of perennial weeds, the spraying of pesticides in the middle and late stages of growth, the best results. In the early stage of perennial weeds, the ground stems and leaves grow rapidly, and the organic matter is mainly transmitted from the bottom to the top. In the middle and late growth stages, the photosynthesis efficiency of grass leaves is improved, and the organic matter produced is mainly “from top to bottomâ€. At this time, the application of the drug is more beneficial to the maximum amount of glyphosate isopropylamine salt solution absorbed by weeds. Stem root conduction, thus achieving the effect of weeding and root elimination.
Fourth, the water should be less and fine. In recent years, experiments have shown that using high-concentration spraying technology, the amount of water per acre is “one back†(15 kg), and the content of 41% glyphosate isopropylamine salt is controlled at about 200 g, which is equivalent to the same amount of water. The effect of the back is much better. It is worth noting that the application of the drug should be based on the herb, the application of more grass, less planting, and even spraying of the liquid on the majority of the stems and leaves of the weeds is not optimal.
5. Add ammonium sulfate as appropriate. Ammonium sulfate has a synergistic effect on the 41% glyphosate isopropylamine salt solution, and it is preferable to add 0.5 kg to "one back water". Pesticide manufacturers remind everyone: can not add ammonium bicarbonate, urea and other nitrogen fertilizer, otherwise it will reduce the efficacy.
