What are the avoided crops of common pesticides?

What are the "avoided" crops of common pesticides? Pesticides play a very big role in the planting process of crops, it can keep crops away from the infestation of pests and diseases, and can make crops achieve high yield and increase income, but some crops can not use pesticides in the planting process, because these crops are very sensitive to pesticides, once pesticides are used, not only will they cause pesticide damage to crops, but also may reduce crop yields, or even no harvest, and can not use pesticides for crops mainly corn and legume crops, In addition, grapes, cherries, peaches, red dates and other crops are not allowed to use pesticides, mainly because pesticides contain sulfur and phosphorus, which will cause certain harm to crops.

The reason why these crops can not use pesticides is because these pesticides are very sensitive to pesticides containing sulfur and phosphorus, once pesticides containing sulfur and phosphorus appear on crops, then these crops will produce pesticide damage, light leaves are yellow and heavy, then crops will also cause a large area of death because of the appearance of pesticides, these are pesticide pesticides that may occur in crops, so in order to ensure the normal growth and yield of these crops, these crops must not use pesticides in the planting process.

In fact, a lot of pesticides, its main role is to prevent the emergence of pests and diseases, but these crops that can not use pesticides, if there are pests and diseases, it is difficult to prevent, so these crops should be cautious in the process of ordinary management, whether it is the selection of crop seedlings, or in the usual maintenance process of crops, it is necessary to operate in accordance with the relevant maintenance regulations, so that it is possible to avoid the occurrence of pests and diseases, so that crops can grow normally. As a result, there are few pests and diseases, so as long as you take care of the crops carefully, there is no problem.

Commonly used pesticides should not be used on crops, Bordeaux liquid, not on potatoes, tomatoes, peppers, melons, peaches, pears, apples, persimmons. Stone sulfur mixture can not be used on plums, cucumbers, melons, grapes, apricots, kiwifruit, these plants.

Kiwifruit, olives, figs, citrus, peaches, pear trees, these crops generally have requirements for pesticides, and they are very sensitive to some pesticides.

It can not be used for some vegetables, if it is used on vegetables in high temperature weather, it is easy to burn the leaves, and stone sulfur mixture, it can not be used for some fruit trees and potatoes, otherwise it will hinder them, and there is no way to make them grow normally.

Sorghum is sensitive and should not be sprayed, and corn can only be used granules to control corn borer. Cucumber and bean are sensitive to the drug, and 50% emulsifiable concentrate 500 times liquid spray is harmful, and 1000 times liquid may also have slight drug damage. Sugar beets are also more sensitive to phosphine, such as when mixing stuffy seeds, the dose and sucking time should be appropriately reduced.

It is sensitive to leafy vegetables at high temperatures and is easy to burn leaves.

The mechanism of organophosphorus pesticides such as phoxanthaphos to produce discoloration and other pesticide damage is that the hydrophobic organophosphorus pesticide is adsorbed by chloroplast or its surrounding tissues, causing the function of chloroplast to be disordered, thereby hindering the electron conduction reaction, that is, the Hill reaction, inhibiting photosynthesis, and discoloration, the more serious the pesticide damage, the carbohydrate content in the body is reduced, and the total nitrogen amount is relatively increased. The liquid medicine should be used with the mixture, and should not be mixed with alkaline pesticides. The drug is easy to decompose when it is light, and it is best to spray it in the evening when spraying in the field.

Stone sulfur mixture] peach, plum, plum, pear, grape, bean, potato, tomato, onion, ginger, melon, cucumber, etc. The young tissues of grapes, peaches, pears, plums, plums, apricots and other fruit trees are prone to pesticide damage, and the use should be cautious, and it is best to spray in the deciduous season, and do not use it in the growing season or flowering and fruiting period. It has a certain pesticide damage to kiwifruit, grapes, cucumbers and leguminous flowers.

There are some genetically modified crops that naturally develop resistance genes that can be used without pesticides, and this technology is used more on food crops such as rice and wheat and some oil crops, and certain spice plants.

What are the contraindications for the use of pesticides? Pesticides, if used incorrectly, can cause plant damage, pests may become uncontrollable, human health can be harmed, and pesticides may cause soil, air, or water pollution. Pesticide products can also have a negative impact on the environment when they enter waterways.

1. Do not follow the label instructions on the pesticide container, and read and carefully follow all the precautions and instructions provided on the container label before using pesticides. Pesticides should not be used in situations other than those stated on the label, and pesticides should not be used in excess. Protect yourself from exposure by identifying the composition of the pesticide, the correct location for use, and the personal protective equipment to wear when using the pesticide through label instructions.

2. Do not store pesticides in places that children can touch, and try to put pesticides in locked cabinets or sheds when storing pesticides, and ensure dryness and ventilation. It is necessary to keep away from food or feed, and away from children, pregnant women, the elderly, pets, etc.

3. Do not change the packaging of pesticides and store all pesticides in the original labeled containers, and do not put pesticides in food or beverage containers, such as milk bottles.

4. Do not use pesticides in water sourcesPesticides may spread in water or soil, and improper use will lead to pollution of creeks, lakes, rivers and oceans. Limit the use of pesticides to certain areas and never let them enter sewers or creeks. Also avoid sprinkling pesticides on fruits or vegetables to be picked.

5. Do not introduce excess pesticides into the sewer, do not put containers containing pesticides into the trash can, or pour pesticides into the sink, toilet or outdoor drain. Either use all pesticides according to the label until the container is empty, or store the pesticides you don't need for later use. You can also find out where your nearest hazardous waste collection location is located.

6. Do not reuse or burn empty pesticide containers according to the label instructions, dispose of empty containers, do not reuse or burn containers, otherwise it may pollute water supply or natural waterways.

First of all, the concentration should not be too high when using, and do not choose too many pesticides at one time, and do not mix several pesticides together, and be sure to choose professional equipment, and then when spraying pesticides, you must choose to wear neat sets and gloves, masks, and hats.

You can't use well water, you can't adjust the concentration at will, you can't use pesticides indiscriminately, you can't spray indiscriminately, and you can't use toxic ones.

When spraying pesticides, if you don't operate properly for a long time, there is definitely a possibility of poisoning. Especially in today's rural areas, most of the elderly are farming at home, and they are old and have low resistance. However, under normal circumstances, because the cultivated land planted by them is not large, there is no need to apply pesticides all day long, and farmers also know the problems that need to be paid attention to when spraying pesticides, so the phenomenon of pesticide poisoning is still very small.

If you use pesticides as a means of making a living for a long time, there will inevitably be some symptoms of poisoning, because there are too many ways for pesticides to enter the human body, but the degree is different. In the process of spraying pesticides, there are too many ways for pesticides to enter the human body. For example, contact, breathing, mouth and nose, eye conjunctiva, pore absorption, etc.

There is a possibility that pesticides may enter the human body and cause poisoning.

Every year, there will be a situation of poisoning with pesticides, a friend of mine is engaged in drone spraying operations, responsible for the scope of the drone delineation and dispensing, because of long-term contact with pesticides poisoning twice, fortunately not serious. It is definitely not appropriate to spray when it rains, even if the weather is relatively sunny, if there is wind, be sure to spray pesticides along the direction of the wind, and never against the wind. Otherwise, it is easy to cause pesticide poisoning.

Avoid prolonged spraying. In the process of pesticide spraying, try to divide the time and sections, and do not work for a long time at one time. On the one hand, it is due to fatigue, and on the other hand, it is also possible to cause poisoning.

Some aspects that farmers need to pay attention to in the process of spraying. Only by taking protective measures and choosing a reasonable time period and time point can we bring the greatest security protection to ourselves and achieve better results. When playing pesticides, if possible, we should still try to play pesticides backwards, but it is very inconvenient to do so in the rice field, so we can only move forward, and then now there is a high-pressure sprinkler, if the field is not big, you can directly stand on the ridge to play pesticides.

It is also like a corn field, because of the wide distance, it can be slowly retreated while spraying pesticides. This can reduce our chances of being poisoned by pesticides!

1. Do not use live water to prepare pesticides. 2. Do not use well water to prepare pesticides, and 3. Do not arbitrarily increase the amount of water. Fourth, avoid the use of pesticides in rainy days or scorching sun, and fifth, avoid increasing the amount of pesticides at will.

6. Avoid unreasonable pesticide mixing. 7. Do not use expired pesticides at will, 8. Do not spray pesticides during the flowering period of crops, and 9. Do not spray pesticides before crop harvesting. 10. Avoid indiscriminate use of pesticides.

You can't choose very toxic pesticides, you can't spray pesticides in a large area, you can't abuse pesticides, you can't use them when the sun is strong, and you can't choose to be relatively large.

1.Application methods, according to different control objects, adopt different application methods, such as the spray type is for ground weeding and foliar pests and diseases, the upper spray type is for leaf back pests and diseases, the oblique cutting type is aimed at the diseases and pests in the lower part of the rice bush, and the corn borer adopts the method of dim sum and hearting. 2.

Use time, when spraying pesticides, be sure to choose a sunny period, and the temperature can not be too high, otherwise the pesticide will volatilize quickly, can not achieve the desired effect, it is best to carry out at 8-10 o'clock in the morning or 4-6 o'clock in the afternoon.

What are the common misconceptions about <> farmers using pesticides? How can I use pesticides to get the most out of them? Pesticides, insecticides, fungicides, is indispensable in agricultural production, it is the basis for ensuring a bumper crop harvest, its advantages are fast, widespread, labor-saving and time-saving, easy to use.

Its shortcomings, polluting the environment, crop residues and pesticide ingredients, causing harm to the human body. How to use pesticides safely and rationally is related to important measures for food safety, and it is also an effective way to reduce environmental pollution. To use pesticides safely and scientifically, it is necessary to understand the use, method of use, dosage, scope of use, time of use, and the influence of meteorological factorsFruits, vegetables and food crops should be combined with agricultural measures, biological control, physical control, reduce the use of pesticides, and prevent pesticide pollution to crops.

Plant genetically modified disease-resistant and insect-resistant varieties to reduce the use of pesticides, save plant protection costs, and prevent environmental pollution.

Crops can actually leave pesticides, in ancient times there were no chemical fertilizers and pesticides when they were not also planting, now their own crops are not for buying money, or do not play pesticides, not on chemical fertilizers, is a large area of planting can not be a large vegetable pesticides, now planting also pesticides are also trouble-free, generally planted to play a closed drug, the effect is good do not need to be sprayed, with pesticides or because of low investment costs, farming has income, if you don't use it, you have to lose money before manual weeding, unless the food is high, We now plant wild vegetables without pesticides, are manual weeding, the general land planting herbicides are not late, drug residues are not much, if a small area of planting, you can consider the old varieties of corn, such as small grain red, white head cream and other varieties, the whole process of planting without pesticides, not on chemical fertilizers, are artificial weeding planting, and then installed on the visible, so that customers can see every day, so that the best can be sold more expensive, insist on a period of time will definitely have returns.

For example, using too many pesticides at one time, and then not understanding the structural properties of the land and the varieties of crops, blindly using pesticides affects the volatilization of pesticides; When using pesticides, do not choose when the temperature is relatively high or the weather is relatively hot, do not choose windy days, or when it rains, be sure to choose the right pesticides according to the varieties of crops, and pay attention to the agents.

Some people feel that they don't need to use drugs at the beginning of the disease, sometimes they will abuse pesticides, they will use herbicides indiscriminately, they will miss the best time, and sometimes they will use high concentrations of pesticides. It must be targeted, pay attention to the growth of the plant, but also pay attention to the management of the field, and choose the right concentration.

Sometimes a lot of pesticides are used, and a lot of fertilizers are used, and sometimes the best time is missed, which will lead to a lack of obvious effect. We must pay attention to the condition of the soil, but also pay attention to the growth of plants at any time, and we must not ignore the prevention and control of pests and diseases.

The use of pesticides is a key link related to the quality and safety of agricultural products, whether from the perspective of food hygiene safety and natural environment ecological environmental protection, or from the aspect of agricultural products participating in market competition, we need to pay attention to the management methods of pesticide use in China to improve the overall level of scientific research and use in China.

The use of pesticides to control plant diseases, insects and weeds has achieved remarkable and rapid results, and has long been accepted by many villagers and people. However, because some people lack the basic knowledge of pesticides, especially the lack of understanding of excellent pesticide varieties, new preparations and their prevention and control objectives, operation methods and other issues, they have five wrong concepts in actual use.

1. Do not distinguish between prevention and control targets, and use medicine when you see it.

Some use insecticides to control plant diseases, some use fungicides to control insect pests, and even use herbicides to control pests and diseases, especially in the case of shortage of pesticide supply, such situations are particularly serious. In this way, if you don't care about the indiscriminate use of drugs and blindly follow the trend of medicine, you will delay the opportunity and jeopardize the actual effect, and at worst it will lead to fertilizer damage and even the extinction of grain crops.

Second, heavy treatment and light prevention, do not spray pesticides if you can't see pests and diseases.

Under normal conditions, the resistance of young juveniles to pesticides is poor, and their resistance to pesticides increases with the increase of insect age. Therefore, it is reasonable to control insect pests at the larval stage or the larval initiation station. However, some farmers often use drugs gradually when the insect pest has been generated, which has led to certain damage, and at the same time, the actual effect of the drug cannot be fully exerted; In the prevention and control of plant diseases, the efficacy of fungicides is not understood, and both defensive fungicides and therapeutic fungicides need to be sprayed when problems arise and are fashionable, which not only leads to the damage of the budget, but also does not have the effect of preventing diseases.

3. Increase the concentration value of the drug at will.

Some people do not follow the proportion when dispensing liquid, do not need professional measuring instruments, only use bottle stoppers or other non-standard containers, there is no total definition, generally greatly exceed the required concentration value, not only lead to consumption, and it is easy to produce fertilizer, at the same time also improve the resistance of pests and diseases.

Fourth, use a single type for a long time.

In the use of pesticides, once it is found that the effect of a certain type of pesticide is very good, it is used for a long time, even if it is found that the actual effect of the drug on the control of pests and diseases is reduced, the type is not changed, but the method of increasing the amount of use is adopted, and the pests and diseases have already formed resistance, and the dose is still expanded, resulting in a vicious circle.

Fifth, confusing with the definition of hazardous chemicals, lack of safety awareness.

At this stage, high-quality pesticides are in the positive direction, slightly toxic, low residue angle development trend, and many farmers do not correctly feel that the poison fruit on the line, only subscribe to the purchase of hazardous chemical pesticides, the lack of understanding of the pesticide pesticides of the slightly toxic and pesticide pests, in the use of pesticides are not in accordance with the pesticide testing standards, will be prohibited in peach trees, vegetables and fruits and raw crops to use pesticides for this crop, resulting in human and animal poisoning.
