What are the pesticides that are advocated?

The use of biopesticides is generally advocated. Because biological pesticides are generally efficient and low-toxic, they are relatively safe for our human body, even when we spray pesticides, the harm to ourselves is not great. There are many biological pesticides used to grow vegetables and fruits, because they can be eaten after about a week, and there will not be too many residues.

Nowadays, many people buy vegetables and fruits, and they pay special attention to organic, safe, green and pollution-free. The use of biological pesticides can greatly reduce one residue of pesticides, which can meet the national standard and become pollution-free crops. <>

Many of the people on our side grow vegetables for sale, and many of them use biopesticides, because the current biopesticides are also very efficient, and if they fail to pass the test, they will not be able to sell the vegetables to the supermarket for sale.

It is also generally advocated not to use highly toxic pesticides and to prohibit pesticides. In general, highly pesticides will have certain residues, which are harmful to the human body and easy to cause health problems. So far, China has banned the sale and use of 33 kinds of highly toxic pesticides, because these pesticides have high residues that endanger human health and are not suitable for consumption.

When we use pesticides, if they do not meet the standards, they are not allowed to be marketed, for example, like this heavy metal residue, like this pesticide residue, if the relevant departments do not meet the standards, then they cannot be marketed, which directly affects our economic benefits. <>

Advocate non-abuse of pesticides. Some people use pesticides in order to save trouble, and basically spray pesticides for a long time in the planting process. In this case, there will be a matter of abuse of pesticides, which will not only affect the crop, but also have a certain residue, and also endanger human health.

The emergence of pesticides can have a good effect on disease prevention and control and insecticide, but it is not recommended to abuse them, so we must master a degree.

Nicotinoid sulfate, borericidal bacillus, pine resin mixture, green worm fungus No. 6, neem oil emulsion, etc., these pesticides can be used.

Biological insecticides and fungicides: Bacillus thuringiensis, Light Chongjun, Metarhizium aeruginosa, Beauveria bassiana, Liuyangmycin, polyantimycin, Jinggangmycin, avirmectin and agricultural antibiotic 120, etc.

Plant-based insecticides and fungicides: pyrethroidin, nicotine, neem, allicin and sesamin, etc.

Generally, biopesticides are OK and relatively safe for the human body.

The rational and scientific use of pesticides can improve the control effect, let me tell you now

The correct and scientific use of pesticides can improve the control effect, delay the development of pest resistance, expand the scope of use, and also expand the scope of use, and at the same time can save manpower and dosage, reduce costs, improve efficacy, reduce toxicity, and enhance the safety of humans and animals. Its biggest advantage is that it does not pollute the environment, which is incomparable to non-biological control pests and diseases such as pesticides. Proper use of pesticides can minimize the harm of pesticides to themselves; It can reduce the spread of pesticides and avoid killing the surrounding crops; It can reduce the degradation rate of the pesticide itself; It can effectively control pests and diseases and improve crop yields.

Different pesticide use machinery has its own special use and performance, in the application of pesticides, spraying, spraying, granulation, poisoning to consider the performance of the equipment and equipment used, the efficacy characteristics are good, can make the agent evenly distributed.

On the surface of crops or pests, to achieve scientific and efficient control effects.

Before using insecticides, it is necessary to understand the control objects, master the appropriate pesticide varieties, and consult the books and manuals of plant protection departments around the country to prevent the abuse of pesticides and achieve the ideal effect of symptomatic application.

With the rapid development of science and technology, there are more and more types of biopesticides, involving animals, plants, microorganisms and other types and biologically related substances with pesticide functions, such as plant-derived substances and genetically modified organisms.

Disease-resistant crops, biomimetic synthesis or modified synthetic compounds of natural products, antagonistic organisms and information of artificially bred pests.

Practical experience has proved that pesticides are harmful to the prevention and reduction of pests, and it is of core practical significance to ensure the increase of agricultural and forestry production. But on the other hand, if the application of pesticides is not scientific, it will also cause adverse reactions, such as insects, silkworms and pest busters, crops, air pollution, pesticide residues in crops and harmful resistance.

Wait. Therefore, in the application of pesticides, it is very important to apply pesticides scientifically, give full play to the efficacy of pesticides, and reduce adverse effects.

In summary, biopesticides are mainly selective and safe for humans and animals; It has little impact on the ecological environment; can induce pest epidemics; It can take advantage of the production and processing of agricultural and sideline products.

The rational use of pesticides should follow the following principles: prescribe the right medicine, apply the slag in the appropriate period, use a reasonable dosage and the number of doses, select the appropriate dosage form and application method, rotate the drug, mix the drug, and use the drug according to the weather.

Related information: the principle of rational use of pesticides: the first to prescribe the right medicine, the second to use the right medicine, the third to use the appropriate medicine, the fourth to mix the medicine, the fifth to the spring ring accurate preparation of pesticide concentration.

Symptomatic use, appropriate use, safe use, prohibition of the use of prohibited pesticides. Prescribe the right medicine, apply the drug in an appropriate time, use the dosage and frequency of the drug of Hepatan Xinli, select the appropriate dosage form and application method, rotate the use of drug resistance, mixed medicine, and use the drug according to the weather. The principles of rational use of pesticides are:

Do not use pesticides in excess of doses, do not use highly toxic and highly toxic pesticides, do not use pesticides one week before harvesting leafy vegetables, and do not use pesticides one month before harvesting fruits and vegetables.

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.

In agricultural and animal products, low-residue pesticides do not pollute the environment in accordance with the recommended dosage, pure hole method and time, while non-biological pest control methods such as pesticides do not compensate for them. As a result of the long-term use of chemical pesticides, some harmful insects have developed strong resistance and can be used to prevent traces, eliminate or control diseases, insects, herbs and other organisms harmful to agriculture and forestry. The rational use of pesticides is to achieve the maximum control effect with the least number of pesticides.

Dosage and method of use of pesticides.

According to the literature, the utilization rate of pesticides is generally 10%, and about 90% of the residues are in the environment, causing pollution to the environment. A large number of lost pesticides volatilize into the air, flow into the water body, settle and accumulate in the soil, pollute the products of agriculture, livestock, fishery and fruits, and transfer to the human body through the enrichment of the food chain, causing harm to the human body. Pesticides can indirectly cause harm to the human body.

The indirect way is that pesticides pollute the environment, gradually accumulate through the food chain, and finally enter the human body, causing chronic poisoning. Highly effective and highly toxic pesticides are highly toxic and remain in the environment for a long time, and when humans and animals eat food containing residual pesticides, it will cause cumulative poisoning. Such hazards often accumulate over a long period of time before they show symptoms and are not recognized;

Most of the cost of organic pesticides is good. Mastering pesticide technology and using targeted pesticides can not only reduce pesticide residues in agricultural products, but also eliminate diseases and parasites and ensure a bumper crop harvest by using pesticides rationally for different crops. Improper or excessive use of pesticides can pollute the environment and water resources.

Pesticide residues and the transfer of pesticides to nature will eventually cause damage from pesticide residue pollution. Pesticide residues can cause pollution and harm agricultural products, animal products and the environment. Contamination from high pesticide residues will be quite severe.
