Iodosulfuron-methyl Sodium

Iodomethylsulfuron sodium salt is a good herbicide in wheat fields and is suitable for many wheat crops. It can remove a variety of weeds and is quite effective.
In winter wheat fields, this medicine is quite suitable. At that time, the weeds were just germinating and were still young and weak. Applying iodomethylsulfuron sodium salt can effectively curb the growth of weeds. Such as common broad-leaved weeds such as Artemisia sativa and shepherd's purse, when encountering this medicine, the vitality is gradually lost, and it is difficult to compete with the wheat seedlings for nutrients, sunlight and space, and the wheat seedlings thrive.
Spring wheat fields are also its use. In spring, when the temperature is gradually rising, weeds germinate rapidly, and iodomethylsulfuron sodium salt can intervene early to inhibit weed germination. Weeds such as quinoa and quinoa, under the action of this medicine, it is difficult to spread wantonly, ensuring that the growth environment of spring wheat is suitable.
In addition, barley and oat fields can also be removed with sodium iodomesulfuron salt. The growth characteristics of these two crops are different, but sodium iodomesulfuron salt can be adapted. For grass weeds such as Mai Niang and some broad-leaved weeds, the medicine has a good control effect, maintaining the ecology of barley and oat fields and promoting their harvest.
Then apply this medicine, it needs to be done according to the norms. The dosage is accurate and the timing is appropriate, so that it can not only remove weeds, but also not damage wheat crops, maintain the balance of field ecology, and harvest crops.

Iodomethylsulfuron sodium salt is a medicine used to control weeds. Its usage is very particular, and specific procedures must be followed to achieve the best control effect, and to ensure the safety of crops and the environment.
The timing of application is critical. It is advisable to choose the medicine when the weeds are young. At this stage, the weed resistance is weak, and the medicine is easy to play an effect. For example, in winter wheat fields, it is better to apply the medicine from the three-leaf stage to the end of the tillering stage of wheat seedlings and the second to four-leaf stage of weeds. At this stage, the weeds grow vigorously, the absorption of the medicine is good, and the control effect is very good.
The dosage of the medicine must be accurate. It depends on the weed species, density and soil fertility in the field. Generally speaking, the dose of active ingredients per mu is about 1.5-3 grams. If the dose is too low, it is difficult to effectively kill weeds; if the dose is too high, it is easy to cause drug damage, damage crops, and pollute the environment.
The application method should not be ignored. The spraying method is often used to prepare the drug into a uniform liquid, and it is evenly sprayed on the stems and leaves of the weeds with a backpack sprayer or a motorized sprayer. When spraying, the nozzle is 30-50 cm away from the weeds to ensure that the fog droplets cover the weeds finely and evenly, without leakage or heavy spraying.
The application environment also has requirements. It is better to choose a sunny and windless day with a temperature of 10 ° C - 25 ° C. The drift of the drug caused by wind Dayee not only reduces the efficacy of the drug, but also may endanger the surrounding sensitive crops; if the temperature is too high or too low, it will affect the activity of the drug and the absorption capacity of weeds, which will be unfavorable to the control effect.
It is also necessary to properly manage after applying the drug. Pay close attention to the death of weeds and crop growth after the drug. If the control effect is not good, it is necessary to analyze the cause and spray it in a timely manner if necessary. At the same time, avoid grazing in the field where the drug is applied or letting livestock and poultry enter to prevent accidental ingestion and poisoning.
In this way, carefully follow the usage of sodium iodomesulfuron salt to effectively control weeds, protect the strong growth of crops, and maintain the ecological balance

Iodomethylsulfuron sodium salt is a highly effective sulfonylurea herbicide. Its mechanism of action is delicate and complex, allowing me to explain in detail.
This agent enters the body of weeds like a surprise soldier deep into the enemy camp. It will be quickly absorbed by the roots, stems and leaves of weeds, and then conducted in the body of weeds. Its key target is acetyllactic acid synthase (ALS). ALS plays a crucial role in the biosynthesis of amino acids in weeds and is an enzyme necessary for the synthesis of branched-chain amino acids such as valine, leucine and isoleucine.
Iodomethylsulfuron sodium salt acts like a precise sharp blade and binds closely to ALS, which strongly inhibits the activity of this enzyme. As a result, the synthesis process of branched-chain amino acids in weeds came to an abrupt stop. Branched-chain amino acids are of great significance to the growth, division and protein synthesis of weed cells. Once their synthesis is blocked, weed cells cannot grow and divide normally, and new proteins are difficult to synthesize.
Subsequently, the physiological metabolism of weeds is chaotic, and many physiological activities are unsustainable. From the appearance, it can be seen that the growth momentum of weeds gradually slows down, and the leaves begin to fade green and yellow, and eventually wither and die. Due to its unique mechanism of action, sodium iodomesulfuron has excellent control effects on many broad-leaved weeds and some grasses. In agricultural production, it is an effective "guardian" to protect crops from weeds and thrive.

Iodomethylsulfuron sodium salt is a commonly used herbicide in wheat fields. When using it, many matters need to be paid attention to.
First, the timing is quite critical. It is suitable for applying medicine in the 3-5 leaf stage of winter wheat and the 2-4 leaf stage of weeds. At this time, the resistance of weeds is weak, the resistance of wheat seedlings is strong, the efficacy of medicine is good and the safety of wheat seedlings. If the medicine is applied too early, the weeds have not appeared; if it is too late, the resistance of weeds will increase, and the wheat seedlings will also be vulnerable to drug damage.
Second, accurately control the dose. Be sure to follow the label instructions and local agricultural technology suggestions to prepare the medicine, and do not increase or decrease it at Overdose, or cause drug damage, the ecology of the wheat field is also affected; insufficient medication, poor herbicide effect, and weeds are difficult to remove.
Third, the drug needs to be dispensed in a proper way. First, use a small amount of water to prepare the drug into the mother liquor, fully stir well, then pour in enough water, and continue to stir to ensure that the drug is evenly dispersed, so as to ensure the stability of the drug effect.
Fourth, pay attention to the way of applying the drug. It is advisable to choose a windless and sunny day, and work when the temperature is above 10 ° C, which is conducive to the absorption and function of the drug. The spray should be uniform and thoughtful, so that the stems and leaves of the weeds are fully medicated, and do not re-spray or leak.
Fifth, pay attention to This medicine drifts strongly, pay attention to the wind direction when applying the medicine, and stay away from sensitive crops to prevent the medicine from drifting and causing damage to neighboring crops.
Sixth, properly dispose of it after the medicine. The used medicine equipment should be cleaned in time, and the remaining medicine and packaging should be properly stored and disposed of. It should not be discarded at will to avoid polluting the environment.

The influence of fomesulfuron sodium salt on the environment is of great concern to many people. This agent is in the soil, and its residual state is related to the growth of subsequent crops. If there is too much fomesulfuron sodium salt in the soil, subsequent sensitive crops such as rapeseed and soybean may be damaged by the drug. The development of its young buds and roots may be hindered, causing the plants to dwarf, the leaves to turn yellow, and even wither and die, and the field scenery may appear to be damaged.
And it also has an impact on water bodies. Rainwater initializes, and the medicine flows into ditches, rivers, or causes water pollution. The living environment of aquatic organisms changes, and the growth of algae may be inhibited, which destroys the balance of water ecology. Aquatic animals such as fish may suffer from damage to their physiological functions, reproduction and growth, and the vitality of the waters may gradually decline.
Furthermore, although there is no direct and significant impact on the atmospheric environment, when spraying, the drug particles may be scattered in the air. If people inhale, or damage the respiratory system, causing cough, asthma and other diseases.
In short, the impact of sodium iodomesulfuron on the environment involves soil, water, atmosphere and many other aspects. When applying medicine, be careful and weigh the pros and cons to ensure the safety of the environment and ecological balance.
