I am a vegetable farmer, what are the common pesticides?

Inorganic pesticides, plant-based pesticides, organic synthetic pesticides, microbial pesticides, and biological agriculture are all relatively common types of pesticides.

7 kinds, namely full killers, fungicides, insecticides, herbicides, rodenticides, regulating plant growth agents, nematicides.

There are mainly 5 types, which are insecticides, fungicides, herbicides, insecticides, acaricides, and so on.

Pesticides can be classified according to their functions, which can be divided into insecticides, acaricides, fungicides, and herbicides. Different categories, targeting different crop diseases, such as pesticides, generally act on insecticides; According to different crops and different pest resistance, the insecticides used are also different. Because of the different ingredients and ingredient content of pesticides, their effects will also be more obvious.

For example, the same company is used for products, Qingdao Zhengdao, when fighting resistant pests, using green cattle, hammers, and Xuange will find that pests and diseases will be killed quickly; But if you use Duhao, the effect of morality will not be so obvious, and the diseases and insects will still die but slowly; This is due to the fact that pesticides contain different active ingredients.

Classification of use, chemical structure, ** classification. Classification according to main uses: pesticides can be divided into insecticides, pupalicides, insecticides, nematicides, herbicides, plant growth regulators, insect growth regulators, rodenticides, etc.

Classification according to chemical structure: existing pesticides can be divided into inorganic chemical pesticides and organic chemical pesticides from a large aspect. At present, there are very few varieties of inorganic chemical pesticides, while there are more and more organic chemical agricultural varieties.

Generally, there are 5 types, namely insecticides, fungicides, herbicides, the other two are acaricides, and rodenticides.

The classification of pesticides includes biological pesticides, mineral pesticides, organic synthetic pesticides and inorganic synthetic pesticides, and fruit and vegetable pesticides.

Preface: With the development of science and technology, there are many types of pesticides, and there will be differences in the process of use. Common ones are pesticides, fungicides, herbicides and other drugs. <>

The state strictly prohibits the use of pesticides in agriculture has six six six, DDT, this pesticide belongs to organochlorine pesticides, the structure is relatively stable, but it is not easy to decompose, the residue is very large, it will accumulate to cause poisoning to people or animals, and there will be a high degree of residue on water and soil air, which seriously pollutes the ecological environment, and there will be residues on grains, fruits and vegetables, and if eaten, it will affect the health of people or animals. Xilisheng and Sailisan pesticides are also prohibited, these two pesticides belong to the preparations, in the environment, food, crops will have a high degree of residues, it is easy to cause poisoning. <>

Toxaphene is an organochlorine pesticide, and the residue is also very high, and the dosage is large, the decomposition is very slow, it is easy to accumulate poisoning, and it has a great impact on the health of humans or animals. There are also herbicides, which can cause mutations or carcinogenic symptoms in animals. In 2001, the sale and use of pesticides were banned, and many pesticides were not allowed.

The most commonly used herbicides are non-selective herbicides and selective herbicides, with paraquat and glyphosate being the most commonly used non-selective herbicides. Selective herbicides mainly include dimethyltetrachloride, besulfuron, etc., which are commonly used pesticides in wheat. <>

Pesticides such as corn, potato, soybean, etc., are all used with high-efficiency grass energy, refined grass gram and other pesticides. Rice is generally suitable for rice, hydrofluoroxa. Seedlings such as fir trees, yew trees, and Pinus tabuliformis are treated with herbicides for forests.

When using pesticides, it is necessary to divide the treatment of the house object to choose, common insecticides, fungicides, herbicides, etc. on the market, their functions are not the same, when achieving bactericidal effect, there are also advantages and disadvantages, if a pesticide is used for a long time, it will not be effective for some pests and diseases, so when choosing pesticides, it is necessary to identify the types of pests and diseases.

There are two kinds of pesticides used by farmers: insecticides and herbicides, after all, pesticides are essential drugs to make crops grow better, and herbicides are essential for farmers to prevent the nutrients of crops from being absorbed by weeds.

According to the raw materials, it can be divided into organic pesticides, inorganic pesticides, plant pesticides, and microbial pesticides. Such as dimethoate, leafhopper powder, sulfacarb, dixone, 402, pyrethroid pesticides, etc.;

The pesticides used by general farmers are insecticides, fungicides, herbicides, insecticides, acaricides, plant regulators, snailicides, and nematicides.

The more commonly used are insecticides, fungicides, herbicides, and then also plant growth regulators, rodenticides, and acaricides.

This problem is relatively general: there is a large gap between the use of different varieties of vegetables, and some varieties are more sensitive. The basic diseases on vegetables are downy mildew, gray mold, etc.; Nightshade vegetables also have cotton rot and so on.

Main pesticides: single or compound dosage forms of enoylmorpholine, mancozeb, cyanide frosturea, pyrimemychlor, ethyldicarb, etc. Basic Pests:

aphids, planthoppers, leaf flies, etc.; Main drugs: imidacloprid, acetamiprid, thiamethoxam, etc., such diseases are multiple, and insect pests are more resistant.

(1) According to the classification of control objects, it can be divided into insecticides, acaricides, molluscides, nematicides, fungicides, herbicides, plant growth regulators, rodenticides, etc.

2) According to the classification of **, it can be divided into mineral pesticides (inorganic pesticides), chemical pesticides (organic synthetic pesticides), biological pesticides, plant-derived pesticides, biochemical pesticides, genetically modified organisms, natural enemy organisms, etc.

3) According to the toxicity classification of pesticide raw materials, it can be divided into high (severe) toxic pesticides, toxic pesticides, low toxic pesticides, etc.

4) According to the classification of chemical structure, it can be divided into inorganic chemical pesticides and organic chemical pesticides.

Classification by poisoning:

1 He who dies immediately after drinking;

2 He who drank it did not die;

3 He who drank it was half dead.

Most of them are classified by chemical structure.

Chemical structure: organophosphorus, organochlorine, pyrethroid use classification: can be divided into insecticides, fungicides, acaricides, rodenticides, herbicides, specific agents and plant growth regulators.

**Classification: It can be divided into mineral pesticides, plant pesticides, organic pesticides, microbial pesticides mode of action classification, insecticides to kill pests usually have four modes of action: contact killing, stomach toxicity, fumigation and systemic absorption.

The classification of dosage forms can be divided into old dosage form emulsifiable concentrate, suspension agent, water emulsion, concentrated emulsion and micro emulsion, wettable powder, water-based dosage form and water-dispersible granules.
