What are the keys to using herbicides to avoid pesticide damage in fruit trees?

Fruit trees can use glyphosate, acetochlor, glyphosate, alachlor and other herbicides. When it comes to using fruit tree herbicides, there are a few issues to be aware of. The timing of the application is very important.

Whether it is pre-sowing soil treatment, post-sowing pre-seedling treatment, or post-seedling stem and leaf treatment, there are different application techniques. The application method should be reasonable, and it should not be sprayed on fruit trees during the application process, and it must be applied on a sunny day without wind.

In addition to topdressing the soil, fruit trees also need to be sprayed with 1% 2% urea or potassium dihydrogen phosphate solution on the leaves, which has a significant effect on promoting crop growth and improving crop disease resistance. According to the crop growing season, it is necessary to appropriately increase the number of tillage of loosening the soil, and the tillage must be from shallow to deep, enhance soil permeability, improve soil temperature, and promote the activity of beneficial microorganisms. The application of chlorsulfuron on peach trees will cause pesticide damage, and in severe cases, it will cause the tree to weaken, the leaves to curl, the branches to shrink, and the fall of leaves.

The drug can also affect the normal growth of peach trees.

The application of the drug in the greenhouse of the peach tree will also affect the nutrients absorbed by the roots of the peach tree, so that the peach tree will grow poorly, and in severe cases, it will lead to the death of the peach tree. It will also make the peach tree grow a small root system, which is the root of the growth of the peach tree, and in severe cases, it will damage the normal growth of the peach tree. During the flowering period of peach trees, the application of this drug may cause a decrease in the number of peach blossoms, thereby affecting the normal growth of peach trees.

In addition, the drug will inhibit the growth of peach trees, and in severe cases, it will cause the death of peach trees.

Fruit tree herbicides must not be mixed. After a large amount of fruit, the residue of the drug on the fruit will cause the fruit to be burned by the agent, and the fruit after being burned will also produce pesticide damage, which will cause the fruit to deteriorate in severe cases. Spraying the drug before the tree blooms and during the fruit expansion period will cause the flowers and fruits to be attacked by the agent at the same time, resulting in the flowers and fruits being attacked by the agent at the same time, resulting in the fruit becoming smaller.

That's all for this issue, thank you**. Interested friends can follow it.

First of all, it should not be used in hot weather or rainy weather, and then when using it, you should also pay attention to the reasonable efficacy, you should also pay attention to the way of observation, and you should also choose the right type according to the crop, and you should do a good job of protection.

Be sure to use herbicides scientifically, don't use too much, don't spray herbicides at will, grasp the concentration of spraying, master the way of spraying, and grasp the timing.

Do not mix multiple fruit tree herbicides, some growers think that the combination of several herbicides to achieve the purpose of weeding, but this may achieve unexpected results, and in serious cases, it may harm fruit trees.

More and more orchards refuse to use herbicides, let's find out what are the dangers of herbicides!

It is best not to spray herbicides on fruit trees, it will definitely have an impact, if you can use tree guards to prevent germs, kill bacteria when suffocating, prevent virus replication and infection, and improve the immunity of fruit trees.

In the season suitable for the application of fruit tree herbicides, different fruit trees have different levels of herbicide tolerance, and unreasonable operation methods are prone to pesticide damage, resulting in fruit tree flowers falling and fruit dropping. Different fruit trees have different methods of weeding, and if the herbicide is not applied properly, it will cause greater harm to the fruit trees and affect the yield of the fruit trees.

Choose the right variety. Each herbicide has a strict range of application, and different crops need different varieties of herbicides, even if the same crop needs different herbicides at different growth periods and different stubbles. For example, butachlor and acetochlor, although only one word difference, the former is suitable for paddy fields, and the latter is suitable for dry fields.

Therefore, when purchasing medicines, you must choose the label that is consistent with the object you need to prevent, and the use method is suitable for you. When there are several varieties to choose from, it is necessary to choose varieties with good efficacy, low toxicity, less residue and good safety. It is necessary to use new varieties with caution, and for new varieties that have not been used, you can first test in a small area, or understand the results of surrounding users, and then decide whether to use or not.

Banana seedlings are sensitive to glyphosate, so pay attention to spraying, and avoid drifting and touching the surrounding branches and leaves of pears, citrus, red grapes, and fruit trees when using them, so as to prevent damage from their pesticides. Diuron red grapes planted in sandy soil and gravelly soil are not suitable for application, otherwise the pesticide damage will be more serious; In the application of jackfruit orchard, due to the long residual time, after several applications of diuron, there are residues in the rhizomes and leaves of jackfruit, so other types of herbicides should be selected or replaced with other herbicides to avoid pesticide damage.

Strawberry weeding, if 2,4-d butyl ester is used to control weeds, it will cause the main stem of strawberry to relax, wilt, yellow leaves to fall, and the whole plant to die, resulting in irreparable damage. The herbicide should not be sprayed on the leaves and fruits of fruit trees, let alone sand and soils of fruit trees affected by prolonged drought. In addition, the drift of drugs such as Isoxagrass, 2,4-D butyl ester and other drugs are prominent, especially in the strong current weather in the morning, the fine particles of these two herbicides will drift with the fog for a long distance, resulting in plantation pesticide damage, flowers and dead leaves and fruits, this kind of pesticide damage generally covers a wide area, which is very worthy of attention.

<> weeding of fruit trees can be treated with herbicides such as glyphosate, acetochlor, glufosinate, and alachlor. When using fruit tree herbicides, we must pay attention to some problems, the application period is very important, whether it is pre-sowing soil treatment, or post-sowing pre-seedling treatment, or post-seedling stem and leaf treatment have different pesticide application skills. The application should be reasonable, in the process of applying the pesticide can not be sprayed on the fruit tree plants, be sure to choose a sunny day without wind to apply the pesticide.

1. What herbicides are used for weeding in fruit tree fields

1. Herbicides such as glyphosate, acetochlor, glufosinate, alachlor and alachlor can be used for weeding in fruit trees. Among them, alachlor is a common herbicide for fruit trees, which has the characteristics of high safety and insoluble in water, and spraying in advance can control half-year weeds and annual broad-leaved weeds in fruit tree fields.

2. When using fruit tree herbicides, we must pay attention to some problems, and the application period is particularly important, because whether it is pre-sowing soil treatment, post-sowing pre-seedling treatment, or post-seedling stem and leaf treatment, there are different application methods. The dosage must be well controlled, and different concentration ratios must be formulated according to the texture, sunshine, humidity and temperature of the soil, so as to ensure the normal efficacy of the herbicide.

3. The application method must be reasonable, in the process of spraying the pesticide can not be sprayed on the fruit tree plants, low sprinklers can be used when spraying, try to avoid pesticide contact with fruit trees, and apply pesticides on sunny days without wind. Do not mix a variety of fruit tree herbicides, some growers think that several herbicides will be mixed to achieve the purpose of weeding, but this may achieve unexpected results, serious may also harm fruit trees, so fruit tree herbicides must not be mixed.

Second, how to solve herbicide damage

1. For fruit trees with light pesticide damage, the herbicide solution on the leaves can be diluted by spraying water, which can reduce the herbicide damage to the leaves, because most herbicides are acidic substances, slight pesticide damage can be sprayed with 1% bleach solution, so that the effect will be better.

2. For fruit trees that have caused pesticide damage and the situation is more serious, antidote or other remedial agents must be used in time. For the pesticide damage caused by paraquat, the formula of gibberellin, indoleacetic acid and natural seaweed fertilizer can be sprayed for about 3 days. At the same time of detoxification, growers should appropriately increase the amount of fertilizer according to the growing season of crops and the need for fertilizer, which is conducive to increasing the stress resistance of crops.

3. In addition to applying fast-acting fertilizer to the soil of fruit trees, it is also necessary to spray 1%-2% urea or potassium dihydrogen phosphate solution on the foliar surface, which has a significant effect on promoting crop growth and improving crop resistance. According to the crop growing season, the number of tillage and loosening of soil must be appropriately increased, and the tillage must be from shallow to deep, so as to enhance the air permeability of the soil, improve the ground temperature, and promote the activities of beneficial microorganisms.

The choice of herbicide in the orchard should depend on the specific situation, and different fruit tree varieties, growth stages, cultivation methods, etc. will have an impact on the choice of herbicide. In general, herbicides that have little impact on fruit trees, have a short action time, and degrade quickly.

Here are some commonly used orchard herbicides and when they are used:

Carbamate herbicides such as glufosinate-ammonium, fluoroxalic acid, etc., have long-lasting effects and can control a variety of difficult-to-treat weeds, but they also have a greater risk of toxicity to fruit trees, and need to be used in strict accordance with the instructions and pesticide standards when using.

Pyroxamine herbicides, such as Leanson, dioxuron, etc., can effectively control young herbaceous plants, and the toxicity to fruit trees is low, but it is necessary to pay attention to the reasonable control of the dosage and time when using.

Prochlor herbicides such as prochlor, isolebrachlor pentachlor slag barrage, etc., are suitable for coniferous forests, shrub underforests and fruit forests, etc., which can control a variety of weeds that are difficult to handle, but the toxicity to fruit trees is high, so it is necessary to choose carefully when using.

Herbicides must comply with pesticide use standards when using, use them correctly in accordance with the instructions, and stop using them before the fruit is ripe, so as not to affect the quality of the fruit and human health. It is recommended to consult the local agricultural department for professional advice before use to ensure that the medication is safe and reliable.
