What herbicide can cleanly kill reeds?
Reeds, as a relatively common perennial grass family plant, are a stubborn presence in the minds of many farmers. It is very difficult to eradicate them in one go, and every time the method is wrong it leads to rampant growth. So choosing a pesticide is also a technical job, so what is the most suitable chemical for spraying reeds? Let's take a look together!
1. What chemical to use for spraying reeds
1. For spraying reeds, generally glyphosate isopropylamine salt, glyphosate potassium salt, grass family weed herbicides, haloxyfop-P-methyl, fenoxaprop-P-ethyl and so on are used. Those with sufficient budget can appropriately add urea or brassin, plus organosilicone. These pesticides all have an effect on reeds, and you can choose according to the specific situation.
2. To achieve relatively good control efficacy, it is necessary to kill the underground rhizomes, so the focus is on choosing grass family weed herbicides with systemic translocation properties and suitable application methods.
3. For herbicides, you can choose the non-selective glyphosate isopropylamine salt, glyphosate potassium salt, as well as selective grass family weed herbicides, haloxyfop-P-methyl, etc. Similar herbicides also include fenoxaprop-P-ethyl.
2. Precautions for spraying reeds
1. Haloxyfop is mainly registered for use in broadleaf crop fields, and will cause phytotoxicity to grass family crops; quizalofop-P-ethyl is also registered for use in wheat fields; glyphosate causes phytotoxicity to all crops.
2. The efficacy of herbicides is better when the reed plants are smaller, so pay attention to the timing.
3. After 2-3 years of continuous control, the reed base in the field will become smaller and smaller, so the work cannot be stopped casually.
Although reeds are relatively difficult to eliminate now, everyone should also find the right method and carry out pesticide work in the early stage of their growth. Generally, reeds just at the early stage of growth are still relatively easy to kill. I hope this article can be helpful to everyone.
