Which pesticides are banned on flowers and fruit trees?

Due to the different types of flowers and the differences in growth and development stages, some common flowers often cause critical damage when using pesticides. Therefore, farmers need to pay special attention when using some pesticides, and must not blindly sow some fruit trees and flowers. Otherwise, flowers and fruit trees may die, and leaves may fall.

Everyone thinks that this situation is very bad, so it is very important to use pesticides correctly for sensitive potions. If there are some fruit trees and flowers that are fragile and sensitive, then farmers are not advised to use pesticides casually. <>

Pesticides may also have a good use, as they can also remove pests from flowers and fruit trees. However, in the process of use, it is necessary to pay attention to some things, so as to produce a better effect and effect. If people don't pay attention to this aspect, it will lead to the death of flowers and fruit trees, which can easily cause huge losses.

Pesticides need to be used with great care, because there are many types of pesticides. There are also some pesticides that are more toxic, so you must not use them casually for some flowers and fruit trees. This will not only cause great damage, but also tend to have some bad performance and impact.

Therefore, everyone still pays great attention to this aspect of things, so as to avoid some unnecessary troubles. After all, pesticides are very powerful, and it is also easy to cause damage to some young fruit trees. <>

Although pesticides also have a very good effect, they can also better remove pests and ensure better growth of fruit trees. However, there are some flowers and fruit trees that are also not recommended to use pesticides, which can also cause counterproductive effects and effects. Therefore, we should also pay extra attention and be careful, and we also need to pay special attention when choosing pesticides, so as to ensure the better growth of fruit trees.

Dimethoate, dimethoate, dichlorvos, trichlorfon, stone sulfur mixture: peach, plum, plum, pear and other plants have pesticide damage, pine borer: in the high temperature season to make pomegranate have serious pesticide damage, Bordeaux liquid: pear, apricot, persimmon is prone to pesticide damage.

Prohibited pesticides are: phosphine, methylisothion, systemic phosphorus, carbofuran, aldicarb, methrin, thiocyclophos, chlorazophos, hydramidophos, methocarb, endosulfan.

Phosphine, dimethoate, endosulfan, methylphosphine, methylisothion, aldicarb, amidothion, carbofuran.

Flowers and fruit trees need to be sprayed many times in the stage of growth and development and fruiting, the effect of pesticides is different in different periods, take fruit trees as an example, it is divided into several stages before flowering, after flowering, after fruiting and pruning and leaf pruning need to play some pesticides to prevent fruit trees from getting sick.

To prevent fruit trees from getting sick, pay attention to pesticides.

So what pesticides can be which pesticides can not be played and carefully hit, which pesticides can not be played specifically, we can go to the pesticide company to ask professionals and technical instructors for guidance, there are many farmers Uncle education is not very high and do not know which pesticides are prohibited, so we will have relevant personnel to give guidance when buying pesticides, as far as I understand, such as carbofuran, methocarb, oxymethoate, phosphorus and other pesticides are not suitable for trees to fight.

Now we take fruit trees as an example, there are these stages, first, before flowering, we need to play some nutrient drugs to promote the growth of fruit trees and flowering, and we also need to play some insect drugs to prevent spring, and the drugs that can not be played are some more toxic drugs, some toxic drugs will inhibit the germination and flowering of fruit trees; The second stage is the flowering stage, this stage of the fruit has been solid, we need to play some medicine to help the growth of the fruit, can not play some medicine to inhibit growth and development, at this time can also be equipped with some medicine to prevent the insects from biting the fruit and the red mite medicine on the leaves; After the autumn harvest season, we need to take some medicine to prevent mold poisoning from the roots and trunks of the tree. <

The same is true for flowers, which are divided into several stages, before flowering, after flowering, flowers are generally not as frequent as fruit trees, but they also need to play some anti-insect, anti-rot and anti-leaves, red spiders, and dense worms. When we manage flowers and fruit trees, we must follow the introduction of pesticide companies, and do not buy some drugs that do not meet the requirements without permission, so as to ensure the growth of our fruit trees and the health of flowers.

For example, there are Bordeaux liquid, trichlorfon, dimethoate, stone sulfur mixture, pine borer and so on. When using these pesticides, we must use them with caution, do not mix them casually, and we should pay attention to the time and amount of use.

Trichlorfon, dimethoate, dichlorvos, pine borer, stone sulfur mixture, these pesticides are harmful to these plants, must be used with caution.

Plum blossoms, elm plums, cherries, cherry blossoms, peaches, these must be paid attention to when using pesticides, otherwise it is easy to affect the normal growth.

Be cautious when using it, and don't mix it casually. Because in this case, some chemical reactions are likely to occur, and it will also affect the efficacy of the drug, such as some insecticides or some bacteriostatic agents, as well as some growth regulators, which must be used with caution.

Bordeaux liquid, in the growing season of peaches, Li Min feels, lower than the dosage, pears, apricots, persimmons are prone to pesticide damage, higher than the dosage of accompaniment, grapes are prone to pesticide damage, oil emulsion, for some peach varieties are prone to pesticide damage, it is best to use several taboos or cautious pesticides to raise flowers in the deciduous season In order to prevent pesticides from causing harm to many ornamental plants, one is to purposefully switch to other efficient and harmless pesticides, the second is to reduce the concentration of use, and the third is not to spray under high temperature and high humidity conditions.

Due to the different types of flowers, the difference in growth and development stages, often make some ordinary flowers in the use of pesticides pesticide hazards, light defoliation, heavy plant death, resulting in great losses. Therefore, for ornamental plants that are sensitive to pesticides, the correct choice of pesticides is particularly important. Here's a look at the hazards of common pesticides.

Dimethoate, dimethoate: It is particularly sensitive to kiwifruit and should be avoided; It can cause obvious harm to ornamental plants of the Rosaceae family, such as plum blossoms, cherry blossoms, elm leaf plums, crab claw orchids, apricots, pears, etc. Dichlorvos is also very harmful to shrimp cloth and coral flowers.

If dimethoate is sprayed between June and October, the petals will wither and lose their ornamental value.

Dichlorvos: Dichlorvos has obvious harm to ornamental plants such as plum blossoms and cherry blossoms, as well as peaches, apricots, twentieth century pears, and Beijing pears, and should generally be switched to other kinds of pesticides. Dichlorvos also has varying degrees of harm to rhododendrons, steamed willows, kiwifruit, acacia, walnuts, etc.

Pesticides should be used with great caution to avoid unnecessary losses. Trichlorfon: harmful to walnut trees and kiwifruit, so it should not be used.

Apple trees such as golden crowns, carbuncles, and marshals are also prone to pesticide damage; For other apple varieties, it should be sprayed at the young fruiting stage.

Don't use Bordeaux liquid too often. Because this pesticide will reduce the yield a lot, it will also cause pesticide residues, which will lead to falling flowers and fruits, and will also cause great economic losses to farmers, especially when planting kiwifruit, do not use, be sure to use some efficient and harmless pesticides, and then use some low-concentration pesticides, do not spray pesticides in a high-temperature environment, and do not use dimethoate between June and October.

I think there are pesticides, acaricides, fungicides, herbicides and rodenticides. Because these pesticides are not conducive to the growth of flowers and fruit trees, and are not conducive to improving the yield of flowers and fruit trees, and will also cause flowers and fruit trees to appear pests and diseases, so we must pay attention to these aspects when planting fruit trees and flowers.

I understand that pesticides should not be used when growing flowers and fruit trees, because pesticides may cause quality problems in these fruit trees, may cause problems with the fruit, and may even cause poisoning, which may lead to the spread of toxins.

Trichlorfon, dichlorvos, dimethoate, Bordeaux liquid, stone sulfur mixture, etc.

1. First of all, the common stone sulfur mixture and Bordeaux liquid are some fungicides used by farmers, but the stone sulfur mixture and Bordeaux liquid cannot be used in our common peach trees, pear trees, apricot trees, plum trees, etc. It should not be used for their growth and flowering periods.

2. There are dimethoate and oxymethoate, including dichlorvos, which can not be used in kiwifruit, pear trees, apricot trees, and peach trees, and it is best not to use these pesticides, which can easily cause pesticide damage.

3. In the process of planting peach trees, when using some metal particle insecticides, such as mancozeb and mancozeb, etc., if you choose a better quality, fully complexed mancozeb products are no problem, and if the quality of the fungicide selected is not up to standard, it may cause some black spots or black spots on the peach tree. This will affect the commoditability of the fruit.

What pesticides should not be sprayed on flowers and fruit trees?

If you choose a better quality of life, the mancozeb products of Quanluohe, it is actually no problem, but the quality of these fungicides is not up to standard, not fully complexed, this mancozeb is more likely to cause some black spots or some black spots on our peach tree, so that it will cause our fruit to be unsellable. Farmers, cause some losses, so, when we farmers plant fruit trees, we should be relatively cautious when choosing some pesticides, pay attention to some pesticides can not be used for some fruit trees, you can consult more, make some inquiries from the Internet, and then use it after confirmation.

Dichlorvos cannot be used on pears, kiwifruit, walnuts, trichlorfon cannot be used on cherry blossoms, plum blossoms, and stone sulfur mixture cannot be used on peaches and plums.

Dimethoate, dimethoate: kiwi fruit cannot be used. Dichlorvos:

Dichlorvos has obvious pesticide damage to ornamental plants such as plum blossoms and cherry blossoms, as well as peaches, apricots, twentieth century pears and Jingbai pears, and other kinds of pesticides should usually be used instead. Dichlorvos also has different degrees of pesticide damage to rhododendron, mantou willow, kiwifruit, acacia and walnut. Trichlorfon:

It is harmful to cherry blossoms and plum blossoms.

Stone sulfur mixture: peach, plum, plum, pear and other plants have pesticide damage, if used on these plants, it is best to spray in the deciduous season, do not use in the growing season or flower and fruit period.

Killing pine: The use of thiophos to kill insects in the high temperature season has serious pesticide damage to pomegranates, and has certain damage to cruciferous flowers.

Bordeaux liquid: peach and plum are sensitive during the growing season; When the amount is lower than the amount, pears, apricots and persimmons are prone to pesticide damage, and when the amount is higher than the amount, grapes are prone to pesticide damage.

The effect of the drug is long-term, such as methane, which should not be sprayed, on flowers and fruit trees.

Because of the different types of flowers, the difference in growth and development, usually some common flowers in the application of pesticides to produce pesticide damage, light to the occurrence of dead leaves, heavy to cause plant death, resulting in very large damage. Therefore, it is very important to use pesticides appropriately for observed plants that are more sensitive to pesticides.

The misuse of pesticides usually causes some common flowers to cause pesticide damage when applying pesticides, which can cause dead leaves and plant death, resulting in very large damage. Therefore, it is very important to use pesticides appropriately for observed plants that are more sensitive to pesticides. The following is a detailed introduction to the pesticide damage caused by common pesticides.

Dimethoate pesticides, dimethoate: kiwifruit is especially sensitive and should not be used; It can cause significant pesticide damage to angiosperm phylum such as red plum blossom, cherry blossom, elm leaf plum, begonia, apricot, pear, etc.; Dimethoate pesticide grass shrimp coat flower, coral flower damage is also very large, if the application of oxidized dimethoate spray in June and October, often cause the flowers to wither and roll, lose their ornamentality.

Dichlorvos: Dichlorvos has significant pesticide damage to red plum blossoms, cherry blossoms and other ornamental plants and peaches, prunes, twentieth century pears, and Jingbai pears, and should be changed to other types of insecticides under normal circumstances. Dichlorvos is a different level of pesticide damage to rhododendron, mantou willow, kiwifruit, acacia tree, walnut kernel, etc., and should be very cautious when applying pesticides to prevent pests of this plant to prevent a lot of unnecessary damage.

Trichlorfon: pesticide damage to cherry blossoms, red plum blossoms, etc. Dimethoate:

It is harmful to peach, plum, plum, pear and other plants, if it is applied on this plant, it is best to spray it when the leaves fall, and do not apply it in the growth and development season or the flowering and fruiting period. Pinus borer: The application of pine borer insecticide in high temperature season has serious pesticide damage to guava and has certain damage to the flowers and trees of the cruciferous family.

Agricultural streptomycin: peaches and plums are sensitive during the growth and development season; When the amount is less than the multiple, pear, apricot, persimmon are easy to produce pesticide damage, and when the amount is too high, red grapes are easy to produce pesticide damage.
