Herbicide. It can be mixed with pesticides, but the principle of pesticide mixing needs to be followed. Mixing principle: 1. After the two are mixed, no hydrolysis, alkaline hydrolysis, acidolysis or redox reaction will occur.
2. After the two are mixed, it will not affect the physical properties of the liquid medicine, that is, there will be no stratification, precipitation, emulsification, suspension rate reduction and other phenomena. 3. After the two are mixed, it will not increase toxicity and produce drug damage. 4. Organophosphorus and organosulfur pesticides cannot be mixed with copper-containing pesticides.
When is the herbicide sprayed with a good effect 1. If it is a season with low temperature such as winter, spring, and autumn, it is generally chosen to use the medicine from 10 am to 3 pm, and the temperature is more suitable at this time. 2. If it is a summer with high temperature, generally choose to take medicine before 9-10 am or after 4-5 pm. If the medicine is used at high temperature at noon, on the one hand, the water in the liquid medicine evaporates quickly, which is easy to lead to an increase in the concentration of the liquid medicine, resulting in pesticide damage.
On the other hand, when the temperature is too high, the stomata on the foliar surface of weeds are closed, and the absorption rate of the liquid medicine decreases. 3. Spraying herbicides is generally selected on sunny or cloudy days.
It is required that there is no wind or light wind (the wind force is below level 3), the temperature is above 10, and there is no dew on the leaves.
Spring spraying time or according to the season to choose, such as spring, autumn weeding, the afternoon dark is relatively early and the weather temperature is low, in this case it is best to choose about ten o'clock in the morning to spray herbicide, at this time the dew in the field is basically gone, after the herbicide spraying is also conducive to the herbicide absorption and utilization. Summer spraying while summer temperatures are higher and dawning.
It is also relatively early, basically the dew is basically dry at 9 o'clock in the morning, and the dew gradually starts at 7 o'clock in the afternoon, so it can be said that spraying herbicides at 9 o'clock in the morning and four or five o'clock in the afternoon are good choices. From a safety point of view, it is basically hot at 9 a.m. in summer, and transpiration.
It is relatively large, and if the herbicide is forcibly sprayed, its own safety can not be fully guaranteed, so it is more recommended to spray in the afternoon.
Wheat field herbicides are selective chemical agents, which are used to control broad-leaved weeds such as pig seedlings and Artemisia annua.
and camelina herba, 10 grams of 10% phenyiosolon or 1 gram of 75% superstar per mu, mixed with 40 kg of water to spray evenly, and the control effect can reach more than 95%. to grasses such as wild oats.
For the prevention and control of knotted wheat and candle grass, 40-50 ml of hussar or 20-25 ml of 3% shima per mu, and 50-100 ml of the product additives are mixed, mixed with 40 kg of water and sprayed evenly, and the control effect can reach more than 85%. <>

It is best not to use it at the same time, the general pesticide is to give vegetables or crops insect control and other effects, mixed herbicides will destroy crops and vegetables together, because they also belong to the scope of herbicide elimination, so it is not recommended to mix them.
-
You can check whether pesticides can be mixed with each other**, see which herbicide and which pesticide are mixed, whether it is feasible, and then you will draw conclusions.
-
Herbicides and other pesticides can be mixed and some cannot be mixed, as long as drugs of the same nature can be mixed, such as alkaline pesticides and alkaline pesticides can be mixed, and acidic pesticides can not be mixed.
-
It is best not to mix herbicides with pesticides, as this will reduce the effectiveness of herbicides and waste pesticides.
-
Hello, lactation herbicides and pesticides can not be mixed, herbicides are professional to do a good job of weather before use. They all belong to cosmetics together and may reduce their active ingredients.
-
No. The functions of the two are different. Herbicides are herbicidal and pesticides are insecticidal. After the herbicide and pesticide are mixed, spray on the crop to affect its growth, and spray it on the weeds, and the weeding effect is not good. Therefore, it is advisable not to mix them.
-
Hello, herbicides and pesticides are better to separate your use without too much trouble. It is better to apply herbicides first and then pesticides, so that the effect is better.
-
Herbicides and pesticides should not be mixed, one should be used and then another.
-
It's best not to mix them.

Herbicides are also a type of pesticides, and this concept should always be there. Whether the two pesticides can be used at the same time depends on whether the components between them will react, if there is a substance that can react, it will reduce the efficacy of the drug and even produce toxic substances to harm crops, and it can be used at the same time if it does not react. However, if you want to control weeds, it is recommended to use herbicides first, and then use other types of pesticides after they have worked.
-
First of all, it is necessary to relieve the medicinal properties of herbicides and pesticides, especially in terms of acidity and alkalinity, if one is acidic and one alkaline, it must not be mixed, and there is no possibility that two or more herbicides and pesticides interact with each other to reduce the efficacy or produce pesticide damage, if there is no above problem, it can be used at the same time.

Looking at the description of the merchant of the product, some chemical ones can be used, but microbial and plant-derived ones should not work.

Summary. Herbicide refers to a type of substance that can completely or selectively kill weeds, also known as herbicides, to eliminate or inhibit plant growth. Among them, sodium chlorate, borax, arsenate and trichloroacetic acid have a dead effect on any kind of plants, and their effects are affected by three factors: herbicides, plants and environmental conditions.
According to the function, it is divided into incidal and selective herbicides, and most of the selective herbicides, especially nitrophenol, chlorophenol, and carbamate derivatives, are effective. The development of herbicides in the world has gradually stabilized, mainly developing varieties with high efficiency, low toxicity, broad spectrum and low dosage, and disposable treatment agents with little environmental pollution have gradually become the mainstream. The commonly used varieties are organic compounds, which can be widely used to control weeds, shrubs, trees and other harmful plants in farmland, orchards, flower nurseries, grasslands and non-arable land, railway lines, rivers, reservoirs, warehouses and other places.
Hello, we are happy to answer the question of herbicides and pesticides that can be used at the same time.
Yes pro. Herbicide refers to a type of substance that can completely or selectively kill weeds, also known as herbicides, to eliminate or inhibit plant growth. Among them, sodium chlorate, borax, arsenate and trichloroacetic acid have the effect of dead wild slag on any kind of plants, and their effects are affected by three factors: herbicides, plants and environmental conditions.

The first thing is to choose the right variety, then be sure to choose a safer combination, and then pay attention to the appropriate observation time, and then you also need to pay attention to the concentration of herbicides.
-
When using herbicides, it is important to pay attention to the drug content of herbicides, and no chemical reactions can occur in the herbicide drugs.
-
To understand the composition of each herbicide, also pay attention to the instructions for use, choose the right herbicide, and learn to dilute the dosage.

Post-emergence herbicides should not be mixed with pesticides. Herbicides and insecticides contain different ingredients and are used in different places. Herbicides are generally sprayed on the ground and weeds, and insecticides are mainly sprayed on plants.
If it is mixed, the effect is not good, and it is likely to cause drug damage. At the same time, care should be taken when using pesticides. If post-emergence herbicides have been sprayed, organophosphorus pesticides such as methamidophos, dichlorvos, cicadas, etc. should not be applied.
Within 7 days to avoid drug damage.
Post-emergence herbicides are not a substitute for pesticides. Post-emergence herbicides are mainly used to kill or control weeds in the process of plant growth, and herbicides are mainly used to prevent, kill or control pests and insect pests in the process of plant growth. Therefore, their different functions cannot be substituted for each other.
