What are the ways to use herbicides?

Introduction: Many farmers in rural areas will have their own fields and plant some crops, but there will be weeds when crops grow, and weeds will rob crops of nutrients for the land, which must be removed, so farmers often spray herbicides on crops in their lives. So what are the ways to use herbicides?

1. Manual spraying - pay attention to the ratio of herbicide medicine and water.

When farmers grow crops, the fields may not be very large, and in many fields where irrigation technology is lacking, farmers generally choose to spray herbicides by hand. After mixing the herbicide and water in proportion, they go to the field and spray it themselves, and there is also a special tool for the sprayed drugs. Different crops have different endurance to herbicides, and the ratio of herbicide and water must be appropriate before spraying, so that crops can not be killed because the pesticide concentration is too high.

After making all preparations, you should also pay more attention to the temperature of the herbicide, because the effect of herbicide weeding is also related to the temperature. The higher the temperature, the more effective the pesticide will be against weeds, and the more effective it will be to control weeds. Therefore, when spraying pesticides, pay attention to the temperature used, so that you can maximize the effect of the drug and prevent your efforts from being in vain.

And when spraying pesticides, you should also pay attention to the weather conditions, rainy days can not spray drugs, because it is easy to get pesticides themselves, and the temperature is low in rainy days, which will reduce the effect of pesticides;So in order to get the most out of your herbicide, choose the right weather and temperature. <>

In many large farmlands, there will also be high-tech products specially used to spray pesticides, and even spraying, which can not only protect workers from pesticides, but also reduce a lot of manual labor, which will be very convenient, although the cost is a bit high, but for some large and important crops, you can replace labor in these ways.

It can be used in a blended version of pesticides, or directly with pesticides, or with water, with insecticides, and with anthelmintics, which are all relatively common ways to use.

It is necessary to choose the appropriate concentration for use, to be targeted, not to abuse herbicides, but also to pay attention to the way of spraying, and pay attention to the location of spraying.

Our country has a long history of agricultural development, and in agricultural production activities, intelligent and brave working people have also invented a series of agricultural stationery, including hoes. Having said that, in agricultural production, the most troublesome thing for farmers is the weeds in the field. Compared with crops, weeds have a shorter growth cycle, a fast growth rate, and at the same time tenacious vitality, and will compete with our crops nutritionally, making the growth of crops worse.

With the development of science and technology, a variety of herbicides have poured into agricultural production for the convenience of farmers.

For herbicides, it is a kind of agent that can make weeds completely or selectively die, but due to the different ingredients, the agent will have more or less impact on crops, so the rational use of herbicides is particularly important. Next, let's talk about the method of infiltration spraying of herbicides.

Depending on the type of herbicide, we make a note on the use of herbicides. For stem and leaf treatment agent, we have to prepare a watering can, the types of watering cans are various, we have to choose the right watering can, the weeding picker solution is mixed with a large amount of water, strictly in accordance with the instructions for proportioning, and then we have to choose sunny weather, high temperature, windless days for treatment, and then evenly sprayed, so that it can be conducive to the effect of herbicides. For the soil treatment agent, we need to mix the agent according to the instructions, and then use a suitable watering can to evenly spray the surface of the soil to form a certain thickness of the chemical layer.

In this way, the drug layer can directly contact the sprouts and seedlings of weed seeds, and the root system can be absorbed by contact, thus playing a role in killing weeds. <

In short, for the application of herbicides, we must choose the appropriate type of herbicide according to the requirements of the crop, and strictly operate according to the instructions, so that we can remove weeds more effectively and achieve twice the result with half the effort.

You can use the rain Xiangxiang potato spray, or spray on the roots of the grass, you can also use a fan spray, the feaster or use a more delicate spray head, or you can use a one-sided parallel spray Yan Hu fog method.

First of all, Kuankai is to choose the right herbicide according to the crop, and at the same time should pay attention to the concentration, should pay attention to the time of use, when using must pay attention to the way of spraying the cautious people, and do not choose to use it when the temperature is relatively high or rainy days.

Due to the increase in labor costs, the application of herbicides is becoming more and more extensive. Garden herbicides are mainly divided into trees, ground cover hedges, and lawn flowers. Herbicides are widely used on large trees.

Mainly used for ground covers, hedges, lawns, and flowers. The use of herbicides varies greatly depending on the species and size of the plant. The use of commonly used herbicides and some precautions will be introduced.

Liliaceae, root vegetables, potatoes, and taro vegetables, including leeks, garlic, onions, lilies, garlic, carrots, turnips, potatoes, ginger, yams, etc. Leeks have a short growing period and are harvested frequently, and the leaves are eaten as much as possible without the need for herbicides. If necessary, exposure to toxic herbicides can be chosen and sprayed after the harvest of old leeks.

Garlic, lily, potato, ginger and yam have a long growth period, mainly edible bulbs and tubers can be treated with soil in the early stage of growth, or in the early stage after the seedling stage, and fruits, garlic ether, vegetables can be used Zhuang 2 and so on. The growth period of green garlic, onions, and onions is short, and only the contact soil treatment agent Ruoer can be used; Turnips and carrots can use herbicides that are less conductive, such as herbicides.

Fruits and vegetables, including eggplant, tomatoes, and pepper, should not be treated with stem and leaf treatments. Before transplanting, contact killing soil treatment agents can be used, such as Ruoer dry matter burning, oxazepine or vegetable Zhuang 2, dimethylamine, etc., mainly for contact killing, and the internal absorption and conduction effect is small. Melons and vegetables, including cucumbers, pumpkins, winter melons, loofahs, vegetable melons, bitter melons, bergamot, carob melons, etc.

The use of acetochlor in such vegetables is strictly prohibited. Herbicides should be used for post-sowing soil treatment.

Legumes and vegetables, including kidney beans, cowpeas, raw soybeans, peas, broad beans, lentils, etc. There are many herbicides suitable for vegetable application, but soil treatment herbicides are still the first choice, such as soil treatment after and before sowing, such as dimethylamine, Shuzhuang No. 1, oxazapine, aquatic vegetables, including lotus root, water bamboo, Machen Cigu, etc. Try not to use herbicides for aquatic vegetables.

If necessary, you can choose low-toxicity Lianzhuang No. 1 and grass buster.

The intensity of sunlight is also closely related to the effectiveness of herbicide use. The use of herbicides in strong sunlight is beneficial for weeds to absorb and spread herbicides. Due to the high temperatures in strong sunlight, the activity of most herbicides is enhanced, which can improve the effectiveness of herbicide use, especially when the herbicide responds most to sunlight in stem and leaf treatments.

It should be noted that the sensitivity of various herbicides to sunlight is strong or weak. For example, ether can give full play to its effect after seeing light, and fluorethyl is easy to photolyze and fail after seeing light.

Therefore, farmers must strictly follow the instructions. In dry weather conditions, low atmospheric humidity and low soil moisture are not conducive to the uptake of herbicides by weed roots, which significantly reduces the effectiveness of herbicides. When spraying herbicides on weed leaves, drought will not only prevent the spread of the chemical solution on the leaves, but also inhibit the opening and respiration of stomata and skin pores on weed leaves, limit their physiological activities, slow down the growth of weeds, and greatly reduce their ability to absorb herbicides, which will also inhibit and affect the efficiency of herbicide use.

First of all, the jujube ear search should choose the right type of herbicide, and the soil must be treated in advance before the use of the family banquet, and the mixed use method can also be used.

It is necessary to choose the right proportion, to choose the right concentration of the brigade, to seize the opportunity to spray weeding agents, not to abuse herbicides, to be targeted, to choose the one that has a faster effect.

Then in life, we can often see all kinds of medicines, not only people will get sick, but also some flowers and trees will get sick. At this time, you need to buy some herbicides or fertilizers to provide sufficient nutrients for flowers and trees. So there are many people who are not standardized when using herbicides and cause harm to their crops, so today we are going to talk about how to use herbicides correctly.

To understand the optimal temperature, we must first understand the optimal temperature of the drug, so the effect of the herbicide and the temperature are directly proportional. And the higher the temperature, the stronger the weed's ability to absorb the drug and loosen the body will become, so the activity of the herbicide will be higher, that is, the effect will be better. Therefore, we must pay attention to this temperature when using, so as to be able to exert the maximum effect of the drug, and if herbicides are used at low temperatures, it is easy to produce some pesticide damage.

Choosing to use medicine in dry weather is actually to choose to use herbicides in dry weather as much as possible, because if you use drugs in rainy weather, it is very likely that there are some penetrants in the herbicide. Then there is no way to achieve the efficacy, and secondly, when using herbicides, if there is the influence of wind and rain, it is very likely that these drugs will float to other crops and cause some damage to other crops, so the loss to the farmer is actually very large.

Remember the best time to use herbicidesThis is to remember the best time to use herbicides, so whether it is to kill some insects or kill some germs, then there are some metabolic activities in the plant. Therefore at the time of 20 degrees Celsius and 30 degrees Celsius, it is one of the ambient temperatures at which herbicides are most active, so when a herbicide is used. Try to choose the middle of the day at 9 a.m

00, then the effect of spraying and using herbicides at this time is the best.

To choose the appropriate concentration of herbicides, we must pay attention to the scope of spraying when spraying, we must grasp the time of spraying, pay attention to the ratio of water and herbicides, must be targeted, and can not be used at will.

First of all, you should choose some herbicides with suitable properties, and you should also choose some herbicides with better effects, and you must pay attention to safety when spraying herbicides, avoid spraying on the top of the **, and it is best to wear protective clothing.

First of all, it is necessary to choose the right herbicide according to different situations, and at the same time, we should pay attention to the concentration of herbicides, and we should pay attention to the efficacy of herbicides, and we should also keep a safe distance, and we should also pay attention to the appropriate time, avoid rainy or windy days, and the temperature must be specially adapted.
