What are the ways to improve the insecticidal effect of pesticides?

First of all, it is necessary to choose the right time to spray pesticides, be sure to avoid rainy days, try to choose the morning time, also need to choose the right equipment, and then also need to choose the right medicine according to different crops, and then choose the right agent according to different pests.

Pay attention to the time of insecticide, moderate medication, etc. Pay attention to the time of insecticide, and use the medicine according to the life cycle of the pest; Moderate use of pesticides, control the concentration of pesticides and the amount of drugs.

It is necessary to observe the activity of insect pests, but also to pay attention to the choice of pesticides, but also to pay attention to climatic issues, but also to understand the use of pesticides, to understand the time period of application.

What is the harm of improving the insecticidal effect of pesticides? Today I'm going to find out with you.

Insecticides are a type of chemical fertilizer that is widely used, and pesticides are mainly used to prevent and control agricultural and animal husbandry diseases and environmental health pests in large cities. Naturally, pesticides are all chronic poisons, and most of them are harmful to people, but the level of harm is different. According to pesticides, insecticides are not the same as pesticides, and the key points are divided into:

"Three causes" hazards, acute poisoning, chronic hazards. The hazards of pesticides and insecticides are summarized below.

Incorrect selection and application of pesticides is likely to cause fatal damage such as carcinogenesis, fetal malformations, and mutagenicity. This is also a more serious pesticide and insecticide hazard. Scientific studies have shown that 18 commonly used pesticides and insecticides have very obvious carcinogenicity, and 16 have indicated potential carcinogenic risk factors.

In the face of money and interests, criminals produce and sell pesticides and insecticides, which are strictly prohibited. Among them, dibromochloropropane can cause male infertility, and has carcinogenic and mutagenic effects on animals and plants.

When pesticides and insecticides enter the human body according to the oral and nasal respiratory system, inhalation of a certain amount of drugs is likely to cause acute poisoning in the short term. Acute poisoning is more harmful to pesticides and insecticides, which can cause nerve spasms and even death.

Diffuse is a more insidious pesticide and insecticide hazard. The most harmful is the accumulation of drug effects in the body caused by long-term contact with food residues from pesticides and insecticides, which is a potential threat to people's health. This chronic insecticide harms the central nervous system, destroys kidney function, causes physiological obstructions, and may even harm the urinary system, causing deformities and freaks, leading to cancer.

Even the dangers of chronic diseases should be prevented.

1. Wash fruits and vegetables thoroughly. Rinsing fruits or vegetables under running water is more effective at removing pesticide residues than soaking. 2. Change your shoes when you enter the house.

Outdoors, the soles of your shoes can be covered with pesticide residue, so changing into indoor shoes before entering the door is the most effective way to do so. 3. Use as required. When using insecticides indoors, wear gloves and masks, leave the room after spraying, and open doors and windows to disperse the smell after half an hour.

4. Beware of antibacterial products. Some antimicrobial products can kill or slow the spread of microorganisms such as bacteria and viruses, and are especially important in winter and flu season. They may also contain ingredients of pesticides.

In the process of using pesticides, we usually double or overuse pesticides, because the excessive use of pesticides can be transferred to the soil process to a certain extent through the up and down conduction of the plant, not only pesticides and the use of fertilizers in the soil process has also caused the loss of nutrients in the soil to a certain extent, and its components remain for a long time after the use of the plant will have a great impact on the next crop, perhaps this ingredient is very effective on the crop. However, in the next crop, it will have a toxic effect on the crop.

The harm of this is that it may cause soil damage, it may also cause pesticide damage to the soil, it may also harm crops, it will also cause residues to the land, and it will also affect the growth of crops.

Harming people's bodies and harming plants will cause environmental impacts, so that the nutrients of the soil will be lost, and people will not be able to get pregnant.

What should be done to improve the insecticidal effect of pesticides? The dose should not be too high or too low. Secondly, the concentration of liquid drugs should not be too high or too low.

Too high will lead to the use of pesticides in humans and animals: in the preparation of pesticides, directly add 20 30ml of mu essential oil (or 1000 1500 times dilution) to the prepared agent, which can significantly improve the insecticidal, bactericidal, and marriage effects of the agent, and pesticides with low toxicity to natural enemies, such as apyr, acacia lice urea, cis-cypermethrin, etc., must be used at the appropriate time.

It can be said that the use of plant extract additives to increase the toxicity of agents to parasites is a very convenient, fast and effective method. The effectiveness of pesticides is low. Puppies and mature parasite larvae must be used strictly and in a timely manner, with strong drug resistance, therefore, close attention should be paid to the use before the third stage larvae and nymphs with weak drug resistance, according to the pesticide label instructions, adding water to prepare pesticides will not prevent crop parasites.

To achieve the insecticidal effect, it is necessary to choose the right drug, use the drug at the right time, and pay attention to solving the two easily overlooked problems of application and delivery according to the three factors that affect the efficacy. To prevent aphids, we must use insecticides with strong internal absorption, such as mycelium and aphidicides, and insecticides, such as larvae, must be used to prevent parasites that live on leaves, such as bumblebees and moths. When the parasite is young, the use of drugs has a good effect.

After the third instar, it must be mixed according to the characteristics of the pesticide. Adding the right amount of synergist can improve drug resistance, enhance its insecticidal effect, and prevent the emergence of parasite resistance. When choosing pesticides, it should be possible to combine high-efficiency and inefficient pesticides with the soil, so as to lose the insecticidal effect, the main features:

High efficiency and broad spectrum: Vitamin salt ultra-slow insecticidal properties formula, expand the insecticidal range, ultra-effective against lepidopteran and dipteran parasites, especially underarm beets and twilight nights. The choice of pesticide ingredients is very important.

It can be controlled by spraying insecticides on the ground or mixing insecticides with bait.

1. Pyridoxine. It is a pyridazinone insecticide and acaricide. Moderate toxicity to humans and animals. It has contact killing effect, no systemic conduction effect, good quick effect, and has an effect on eggs, nymphs and adult mites.

2. Tetramitezine. It is a filial piety organic nitrogen heterocyclic acaricide. Low toxicity to humans and animals, good poisoning effect on mite eggs, also has a certain activity on young and female mites, and is ineffective for adult mites, but after Qiaoyuan Jincheng mites are exposed to the medicinal solution, it can lead to a decline in egg production, and most eggs can not hatch, even if the hatched young mites die quickly.

3. Spirodifen. It is a low-toxicity, high-efficiency and long-term acaricide split bond. It has the ability to inhibit the synthesis of fat in the body of pest mites, non-systemic acaricide, and kills eggs, young mites and female adult mites mainly through contact killing and stomach toxicity. No cross-resistance to conventional acaricides. It can control leaf mites.

4. Thia.

Today's agriculture is inseparable from pesticidesInsecticide, weeding or ripening, etc., pesticides have a very big effect, but if the insecticidal effect of pesticides is improved, it can bring both benefits and disadvantages. Improving the insecticidal effect of pesticides can prevent the emergence of some pests, and it can also help remove grasses that are harmful to crops, which can improve crop yields. ButThe downside isBecause pesticides are difficult to be degraded, or can not be degraded, so the impact on the ecological environment is very large, and with the improvement of insecticidal effect, pests will also produce a certain resistance, water sources will also be polluted, excessive use of pesticides, not only will destroy the soil structure, but also affect the growth of crops.

First of allWhen using pesticides, it is necessary to use them when the dew is not dry, so as to enhance the adsorption of the liquid on the surface of the objectIf you ignore the environment of medication, the time of medication, blindly use drugs, use drugs indiscriminately, do not see the instructions for use, and increase or decrease the concentration of pesticides at will, not to mention that it will cause critical harm, and it will also bring pollution to the environment, and finally can not achieve the purpose of insecticide and insecticide.

In addition to that,When dialing pesticides for crops, we must hit its vital parts, and truly prescribe the right medicine and the "bit" medicineIt is best to spray pesticides on the seat again, spray pesticides at the base of the rice at the root of the division or at the top, in short, spray pesticides according to the specific situation of the error.

When spraying pesticides on crops, the most taboo is to use pesticides that fail to rinse the skin, that is, expired pesticidesIn addition to that,Some crops use pesticides, some of which are only suitable for a few crops, if some crops are used on other crops, they will not be ineffective, and they will also produce pesticide damage and toxicityPeople will blindly mix pesticides in order to treat a variety of sick children, in fact, Huang Pei is likely to reduce the medicinal properties after using together, or after mixing, it will cause harm to some crops.

All in allWe must pay attention to many aspects when spraying pesticides on crops.

What are the effective ways to improve the effect of pesticide control?

Many kinds of friends are very concerned about a problem, that is, how to improve the effect of pesticide control, so let me talk about the specific methods.

The first point is to find the time to apply the pesticide and spray it in time. Both early and late will outweigh the benefits. The three borers must use drugs during the peak hatching period to achieve good results.

For the same pest, different varieties of pesticides with the same efficacy can be sprayed alternately, which can overcome the pest's resistance and achieve good control results. For example, aphids and red spiders can be used interchangeably with urine wash mixtures, aphids, conchofen, methamidophos, and phoxanthion.

The second point is to add neutral laundry detergent to the solution, which can increase the control effect by 25%. In 50kg of 50% dichlorvos 1000 times solution, 50g of laundry detergent can enhance the overall adhesion, and the effect of controlling rice planthoppers can reach more than 95%. When spraying pesticides mixed with toxic soil to control insects, add 1kg of waste engine oil or diesel fuel or kerosene to the toxic soil per mu, mix well and apply, which can improve the insecticidal power.

The third point is to choose the drug according to your needs. Diseases, insects and weeds in production should not be used indiscriminately from person to person, so as not to misjudge and cause unsatisfactory control effects. Scientific medication time.

Spraying too early or too late not only fails to achieve the purpose of prevention and control, but also increases costs and pollutes the environment. Before the use of medicine, it is necessary to fully investigate and understand the occurrence, harm and development law of diseases, insects and weeds, and use drugs in a targeted and accurate manner at the best control time to ensure better control results.

The fourth point is to pay attention to the quality of pesticides and the purchase of counterfeit pesticides. Eliminate counterfeit pesticides. When buying pesticides, you must see the identification, certificate number and date on the pesticide packaging, and try to buy brand pesticides produced by large manufacturers.

The effectiveness of low-quality pesticides produced by some small manufacturers cannot be guaranteed, let alone counterfeit pesticides. According to the control object, crop varieties and different growth periods, the appropriate pesticides, dosage forms and dosages can be selected to achieve the best control effect.
