At present, wheat has entered the heading and flowering period in various places, there are many friends who report that there are reeds in the later stage of their wheat fields, because the wheat in this period is very sensitive and fragile, can not be sprayed indiscriminately for the time being, even if it can be used and there is no good effect, there is still a year of prevention and control, so it is a headache to mention the reeds in the wheat field, the reeds in the wheat field are difficult to control because of their vigorous vitality, developed root system, and the reproduction rate is relatively fast, how to prevent this vicious weed? There is no residue, and the key is not to affect the next crop.
Generally speaking, the plot near the ditch canal is easy to grow reeds, especially in the later stage (heading and flowering) at this time the wheat root system begins to gradually decline, because the root system of the reed is developed, so it will compete with wheat for nutrients and water, and the impact of three or two on the yield is not obvious, if there are more reeds in the wheat field, it should be paid attention to, otherwise it will cause a reduction in yield.
However, in addition to the developed root system and fast reproduction, the reed has a waxy layer on the surface of its leaves (relatively thick) and has a particularly strong waterproof and impermeable ability, which is difficult for the general liquid to penetrate, so this is also the main cause of headaches. In addition, if the reeds are not cleaned in the current year, they will reproduce more in the next year, which will not only affect the yield of wheat, but also affect the growth of corn in the next crop.
Reeds are so difficult to control? Is it true that there is nothing to do with them? How to prevent them safely? Today, I will teach you a recipe and master the spraying time, which can have a very good effect. Specifically, 5~7 days before the wheat harvest, spray 250 grams of glyphosate per mu, add 24D dimethylamine salt, plus organosilicon additives, and spray where there are reeds (targeted spraying, spraying evenly and thoroughly), so that the reeds in the wheat field can be effectively prevented.
Why do we recommend you to use glyphosate?Because glyphosate is a systemic conduction broad-spectrum herbicide, plus 24D dimethylamine salt is to make the reed duct thicker and expand, which is conducive to the penetration of glyphosate solution into the roots and plants of the reed, and then mixed with silicone additives, it can also penetrate the waxy layer of the reed epidermis, and has a more penetrating effect, and these agents can be used together to prevent reeds well.
As for why spray pesticides 5~7 days before wheat harvest? This is because glyphosate with 24D dimethylamine salt is a combination of herbicides that kill any crop, but the death time is about seven days, and this period of spraying, seven days after the reed can be completely controlled, and at this time the wheat has matured, so that there is no impact on the wheat yield, and it will not affect the next crop, the key is that the cost of control is not high, the cost of a bucket of water is less than ten yuan, this method is not good.
To sum up, because the root system of reeds is relatively developed, the reproductive ability is strong, and there is a relatively thick waxy layer on the surface, it is more difficult to prevent and remove, especially in the later stage of wheat growth, the reeds in the wheat field give people a headache, and they dare not spray pesticides indiscriminately, for fear of affecting the wheat. In fact, this is not the right agent and the right time, it is recommended that you choose 20 grams of glyphosate 5~7 days before the wheat harvest, plus 24D dimethylamine salt, plus organosilicon additives, can effectively control reeds, low cost, no residue, the key does not affect the next crop.
Friends, if there are reeds in your wheat field and you don't know how to prevent them, you might as well try the methods mentioned above, it works!
