Nicosulfuron, sulfuron, oxazole one three brands of corn herbicides have good effect.
1. Nicosulfuron.
Nicosulfuron is currently the most widely used corn field herbicide, this herbicide Ma Tang, dogtail grass and other effects are better, in the early years there was a kind of "safe" nicosulfuron with a safety agent, claimed to be able to be used in 2-9 leaves of corn, in the past the traditional nicosulfuron corn 3-5 leaf period used.
2. Mesotrione.
Sulfulone is relatively safe for corn, and generally sweet corn can be used, but burst corn and ornamental corn should still be cautious and be careful of pesticide damage. Nitrometrione has a very poor effect on purslane and dogtail grass, and it is not good for older weeds, so it is recommended to apply it early. The effect of mesotrione is better in the south where the moisture is better, and the effect is not good in the north where there is less rainfall, and the cost of use is higher than that of nicosulfuron.
3. Oxazole ketone.
Oxazole is one of the safest corn field herbicides, safe for sweet corn, etc., this herbicide activity is higher, mixability is good, a drug can control a variety of weeds, the effect on fragrant aconite is poor (there are not many agents with a good effect on fragrant aconite), at present, the southern application is less, may be the use of higher cost, after localization is expected to increase sales.

Corn herbicides:
1. Atrazine.
Atrazine is a selective pre-emergence and post-emergence herbicide, since 1958 by the Swiss Geigy company development and production, has been popularized and applied in corn production for more than 60 years, due to its wide range of weeding, clean weeding, good safety, cheap, easy to use and other advantages, has become one of the world's largest herbicide varieties. It can effectively control dozens of common weeds in corn fields such as horsetail, barnyard grass, sedge, kanmai niang, knotweed, quinoa, cruciferous family, leguminaceae, etc., due to the good mixing of atrazine, in order to prolong the application period and improve the weeding effect, atrazine is often mixed with post-emergence herbicides such as nicosulfuron and metrioxone.
2. Nicosulfuron.
Nicosulfuron is a kind of post-seedling stem and leaf herbicide, since the beginning of this century in China registered on the market, due to the high activity of nicosulfuron-on, good weeding effect, high safety, cheap and other outstanding advantages, it has become one of the largest post-seedling herbicide varieties at present. In order to expand the range of weeding and improve the weeding effect, nicosulfuron is also often mixed with other herbicides such as atrazine. It can effectively control barnyard grass, wild oats, dogtail grass, golden dogtail grass, horsetail, cow tendon grass, wild millet, willow leaf thorn knotweed, sorrel leaf knotweed, curly stem knotweed, anti-branched amaranth, nightshade, fragrant herb, water acanthus, camellia, xanthium, chrysanthemum, duck plant, wolf grass, windlily cauliflower, blue cabbage, horsetail, artemisia, spiny cabbage, thistle, borage and other annual weeds and perennial broad-leaved weeds.
Sweet corn and popping corn are sensitive to this agent and should not be used.
3. Mesotrione.
Synchlorotrione is a triketone post-seedling weeding developed by Syngenta on the basis of sulfonone, due to its wide herbicide spectrum, good safety, cheap and other advantages, it is one of the safest herbicide varieties at present, often mixed with herbicides such as nicosulfuron, which can not only expand the range of weeding, but also improve the safety of herbicides, and is one of the herbicide varieties with the best weeding effect. It can effectively control annual broad-leaved weeds and gramineous weeds in corn fields. Especially for weeds such as ramander, amaranth, quinoa, knotweed, barnyard grass, and horsetail.
4. Oxazole ketone.
Oxazolone is the first post-emergence herbicide developed by BASF for maize with pyrazolone benzyl ester, which has outstanding advantages such as wide herbicidal spectrum, high activity, strong mixability, and safety for maize and stubble crops. It has become the most widely used herbicide on special corns such as sweet corn, waxy corn, and burst corn. It is widely used in almost all corn varieties such as ordinary corn, waxy corn, sweet corn, seed corn, burst corn, etc.
It can be used in the corn 3 and 9 leaf stages. It is currently the most widely used herbicide variety in production and the highest safety. Since oxazolone is still in the patent protection period, ** is relatively high.
In order to reduce costs and improve the herbicide effect, oxazolone is often mixed with atrazine, terbutazine and other herbicides.

With the progress of modern science and technology, the level of agricultural planting is becoming more and more scientific and rational. However, in order to make agricultural products grow better and faster, and reduce the impact of pests and diseases on their yields, the use of pesticides is also indispensable. As a chemical agent, pesticides can be used rationally to effectively control natural pests and diseases and regulate the growth of plants.
As the main crop of China's agricultural production, corn occupies an important position in China's pesticide production. Today we are going to talk about the potential variety of herbicides in corn fields - oxazole ketone, do you know what advantages and disadvantages it has?
Oxazole grass, as a benzyl pyrazole herbicide, it has a good preventive effect on weeds resistant to glyphosate, triazal acetyllactate synthase and acetyl-CoA carboxylase inhibitors, and it can effectively control grassy weeds and broadleaf nadiga weeds on corn crops. Oxazole has a wide spectrum of herbicidal, high activity, strong mixing performance, in addition, it is safe for crops and has low toxicity. It kills grass quickly, has a wide range of medicine opportunities, has good low temperature resistance and rain erosion resistance, and is easy to use.
Any product has good and bad, of course, it also has some shortcomings, such as the need to pay attention to the concentration of preparation, improper configuration will lead to the growth of crops and even kill the phenomenon of crops, in addition, the synthetic route is not complete enough, there is a lot of room for optimization and improvement, etc.
In short, when we use pesticides, we should pay attention to the selection of pesticides and the basic configuration methods, and at the same time pay attention to the use of matters, because pesticides have the toxicity of phase holes, we should pay attention to personal safety when using, to avoid poisoning, to bring harm to themselves. For oxazolone, we can choose it very well, because it has many advantages in deficit, it is the safest of all corn field herbicides, and has become the darling of this field.
The use of paraquat herbicide in maize fields can kill bitter herbs. When the maize plant is more than 1 metre tall, spray the weeds (bitter herbs) with 100 ml (contact herbicide) of 20% paraquat mixed with 15-20 kg of water, stir well. Weeds die in 2-3 days. >>>More
Corn herbicides are mainly used to kill dicot plants, and eggplant is a dicot plant, so corn herbicides generally cannot be used in eggplant fields. Moreover, if the previous crop is maize, the large amount of residue when the herbicide is too heavy can also adversely affect the eggplant. Some pre-bud herbicides for corn fields can be used in eggplant fields.
In the process of agricultural planting, it is not uncommon to use the wrong herbicide, that is to say, the herbicide of a certain crop is used on another crop, I don't know how many farmers have experienced, today, the little helper received a message from a friend, he was in the control of weeds in the wheat field some time ago, accidentally used the herbicide in the corn field, and sprayed nicosulfuron as a wheat herbicide, resulting in the wheat has not fully recovered. >>>More
