How do you do the right weeding? What are the ways to use herbicides correctly?

How do you do the right weeding? Herbicides can be used. It is absorbed from the roots or sprouting buds of the plant and must be applied to the soil before weeds appear.

Some herbicides are mainly absorbed from the aboveground part of the plant and must be sprayed on emerging weeds. Some herbicides lose their activity in the soil due to adsorption or rapid degradation, while others are more stable in the soil and remain active for a long time. Therefore, the herbicidal effect of herbicides largely depends on the characteristics of the herbicide and the technology used.

Spray herbicide is to use high-pressure spraying equipment to spray directly on the leaf surface of crops, and the liquid can penetrate into the leaves of crops, making the leaves yellow, so as to prevent the pesticides on the leaves from evaporating to the ground and prevent and control ground diseases and pests; When using the solution, there is no need to rinse the seeds with water. Spray herbicides can be mixed with some herbicides. When spraying herbicides, if you accidentally splash ** or eyes, you should immediately rinse with water to prevent the agent from failing.

3 5 seconds after spraying, you can achieve a better weeding effect. If it is in a high temperature and arid area, it should be sprayed in time to replenish water and maintain the temperature of the solution.

Spraying should be avoided after rain to avoid the loss of the solution. When applying pesticides, when the soil moisture is 60% or 70%, the herbs should be poured out and washed with water. After application, the residual liquid should be discharged in time to avoid polluting the environment again.

If overgrown weeds are found, appropriate measures should be taken to control them and prevent the weeds from reproducing. When spraying herbicides, avoid doing it after rain.

When weeding, the soil and weeds are generally washed with water first, and then the herbicide is evenly sprayed to all parts of the farmland, so that the liquid medicine enters all parts of the farmland evenly. In order to prevent the liquid medicine from volatilizing into the air, you can use a brush or palm to lightly wipe the agent, wipe the agent evenly, spray it on the weeds, and spray the liquid medicine evenly on the leaves of the weeds. Do not pour the liquid medicine into ditches or paddy fields, otherwise it will easily splash on the weeds in the farmland.

In addition to the above methods to use herbicides correctly, there are also strict requirements for the toxicity of herbicides.

We can directly buy some herbicides, and then mix these herbicides according to a certain ratio, and then spray them on some crops to carry out weeding work.

You can mix the herbicide with water first, then put it in a watering can and spray it on the roots of the weeds, which is the correct weeding step.

You can use spray herbicides, spraying pesticides directly on the liquid surface of crops, which can achieve good results.

At this time, you can choose the method of manual weeding, you can also choose to use herbicides, and you should also choose the right pharmacy according to the crop.

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.

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.

Abstract:The correct use of chemical herbicides can greatly reduce the workload of weeding operations in farmland and woodland, which is economical and labor-saving. The following describes the use of several herbicides commonly used in weeding in nurseries and afforestation areas:
