    Slim thighs: When you do exercises for the whole body, you get all parts of your body, including your thighs. The most effective aerobic fitness exercises for your legs and buttocks are walking, cycling, cross-country skiing, and stair climbing.

    Running is also a great way to burn calories, but it's not the best option for people with thick and fat thighs. Because these people will find running difficult and uncomfortable, they will not want to persevere. It's much better to use a combination of walking and running.

    When you're not struggling, you can run more and walk less.

    Swimming is also a whole-body aerobic exercise, but swimming doesn't use the thighs too much. If you want to tone your thighs in the pool. It is possible to walk in shallow water, or in deep water with a life jacket.

    The natural resistance of water will give your thighs a powerful workout. It's the kind of workout you don't get on the road.

    To get the thighs **, each workout takes half an hour. At least three to five times a week. Stick to moderate-to-moderate and moderate-intensity exercise.

    You can also be flexible in terms of exercise intensity and timing. If the intensity of the exercise is lower and it is easier to do, you can increase the duration of the workout, and if you burn fat, walking for an hour is the same as running for 20 minutes.

    Before performing an exercise program. It's a good idea to have your doctor do a physical examination and choose an exercise intensity that is easy to perform without adverse effects. The workout time can be gradually increased in the future, but the average increase in workout time per week should not exceed 20%.

    The best way to self-exercise is to get back to normal within an hour of the workout.

    To prevent injuries to certain parts of the body during exercise. Start by doing some preparatory activities, such as running slowly for a few minutes or doing stretching exercises. The best time to exercise is about 2 hours before meals. Such as early morning and afternoon.

    1. The prepared pesticide can be stored for three months. Most pesticides do not undergo chemical changes when mixed together, so there is no problem in keeping them, and the next time you continue to use them, you can stir them well. It should be noted here that solid pesticides are easy to sink down, so they must be stirred and mixed before use.

    2. In a few cases, pesticide mixing is not suitable, such as pesticides with different acidity and alkalinity, after mixing, a neutralization reaction will occur, if it is sprayed immediately at that time, it may be okay, but if it continues to be placed, it will fully react and cause the pesticide to change or even fail.

    3. Therefore, it is best if it can be used at the time, otherwise in most cases, it can be mixed and kept forever, and it will not change for three months.

    Many pesticides are afraid of low temperature environments.

    General liquid pesticides are divided into emulsifiable concentrate, water agent, water emulsion, water suspension agent, oil suspension agent and so on. Many of them will cause uneven pesticide dispersion or some components to settle due to the influence of low temperature environment. Therefore, in the formulation, we will add some excipients that can resist low temperature environments to improve stability in low temperature environments.

    Generally, chemical pesticides are not afraid of freezing, low temperature is conducive to prolonging the shelf life of pesticides, and biological pesticides are afraid of freezing, and low temperature will reduce biological activity. Chemical pesticides cannot be used immediately after low temperature, because they are chemically synthesized, and low temperature may cause some of their chemical bonds to be broken, which will affect their vitality and reduce the effect!

    Generally, chemical pesticides are not afraid of freezing, and low temperature is conducive to prolonging the shelf life of pesticides. But be careful that the pesticide bottle is frozen and shattered.

    Summary. Hello, glad to answer for you.

    After freezing, the physical and chemical properties of pesticides will change, flocculation, precipitation, crystallization, and stratification, and you should observe them carefully. If the change in state can be clearly observed with the naked eye, and if you continue to use it, it is assumed that the efficacy of the drug will be greatly affected.

    Will the pesticide be effective when it is frozen?

    Hello, I am glad to answer for you that the physical and chemical properties of pesticides after freezing will change, flocculating, precipitation, crystallization, stratification, you have to observe the sedan town well. If it is obvious to the naked eye that the state of the nuclear fan is changing, and if it continues to be used, it is speculated that the efficacy of the drug will be greatly affected.

    Too low a temperature also has a great impact on the quality of pesticides. If the liquid agricultural anti-slip drug encounters a low temperature below 0, the mountain bench will crystallize into ice, reducing the travel force of the milk teaser bridge, resulting in a decrease in drug efficacy. Anti-low temperature pesticides should pay attention to anti-freezing and keep the temperature above 1.

    It mainly depends on what kind of pesticide it is, and the pesticide is mainly the ingredient content that meets the requirements of the label during the validity period. There will be a decrease in the content of expired pesticide ingredients.

    The more potent or qualitative the pesticide is stored in the room, the worse the effect or quality (any drug or food), if the period is shorter, if it is used several times, if the period can be invalidated, if it is used again, it is equivalent to delaying the loss of the drug machine.

    Expired pesticides depend on what ingredients of pesticides are contained, and some expired pesticides are not only reduced in the active ingredients of the drug, but also may have some reactions between chemical components to generate other substances, which will have unforeseen consequences. For example, "acemethamidophos" was originally a low-toxicity pesticide, and it may become a highly toxic pesticide containing "methamidophos" after expiration.

    "Expired pesticides" are not "fake pesticides" or "inferior pesticides", so they are not absolutely unusable. After passing the inspection by a special drug testing institute and following the scientific use method, many expired pesticides still have a certain use value.

    Expired pesticides are different from fake pesticides and inferior pesticides, and the use of fake and inferior pesticides will bring losses to agricultural production and farmers' income. For fake pesticides and inferior pesticides, the production and use of national administrative regulations are expressly prohibited. However, after the pesticide expires, it generally has a certain use efficiency and has a certain control effect on plant diseases and pests.

    Therefore, the sale of expired pesticides is not always prohibited.

    Article 22 of the Regulations on the Administration of Pesticides stipulates: "Pesticide products that exceed the product quality assurance period shall be sold within the specified period if they meet the standards and meet the standards; However, the words 'expired pesticides' must be indicated, along with the method of use and dosage. ”

    According to the provisions, the sale of expired pesticides shall meet the following conditions:

    1) It must be inspected by the pesticide testing agency of the provincial Department of Agriculture or the pesticide verification agency of the Ministry of Agriculture, and still meet the standards of pesticides. If it has been verified that it has lost the efficacy of use, and the expired pesticide that does not meet the pesticide standards stipulated by the state, it shall not be sold.

    2) It can only be sold for a limited period of time.

    3) The words "expired pesticides" must be indicated on the packaging of pesticide products. Since the effectiveness of pesticides will definitely change after they expire, the method of use and dosage must also be clearly stated according to the actual efficacy.

    Expired pesticides that do not meet the above conditions shall not be sold, and the majority of farmers should first find out whether they meet the above conditions when purchasing expired pesticides.
