Reducing pesticide residues should do the following

The following points should be controlled to control pesticide residues :
First, pay attention to cultivation measures
Selection of pest-resistant varieties; rational rotation, reducing soil pests and diseases; cultivating strong seedlings, rational close planting, rational fertigation; seed disinfection and soil disinfection;
Second, take biological control methods
Give full play to the field of natural enemies to control pests control, the first choice of cultivation methods for survival and reproduction of natural enemies to keep the environment to survive predators, pests damage crops if it is found, should avoid the use of lethal predators large chemical pesticides, biological and preference should be given Pesticides , followed by physical methods, trapping pests such as lamp lure, taste and so on.
Third, the selection of low-toxic, low-residue pesticides
In the middle and late stages of crop growth, when farmers use pesticides to control crop diseases and insect pests, they can use low-toxic and low-residue pesticides for prevention and control. It is strictly forbidden to use high-toxic and high-residue pesticides such as carbofuran, methamidophos, omethoate, etc. .
Fourth, choose the pesticide, carefully read the pesticide label
Select the pesticides for the mouth, carefully read the pesticide labels, control the concentration and the number of uses, use reasonable methods of medicine, rotate the different types of pesticides to prevent the occurrence of resistance to pests and diseases, and strictly implement the safe interval of pesticide use.
Pesticide residues are phenomena in which a part of pesticides directly or indirectly remain in grains, fruits, vegetables, animal products, aquatic products, and soils and water bodies after the application of pesticides in agricultural production. Reasonable control to reduce residue!

Plier Series

Common types and uses of pliers
Pliers have many functions and are used in many industries. The pliers used in different industries are also different. Generally, the more commonly used pliers are:
1. Wire stripper
Wire strippers are commonly used tools for internal electricians, motor repairs, and instrumentation electricians. They are composed of knife edges, crimping ports and clamp handles. They are mainly used for stripping plastic and rubber insulated wires and cable core wires.
2. Wire cutters
Also called a vise, it is a kind of clamp and cutting tool. It is composed of jaws, tooth edges, knife edges, guillotines and pliers handles. It is mostly used to pick up nails or break nails and iron wires.
3. Nozzle pliers
It can be divided into electrical and electronic categories. It is mainly used for cutting injection molding machine products, plastic products, and injection nozzles. It is also suitable for cutting metal products and electronic component pins.
4. Needle-nose pliers
Also known as trimmers, pointed pliers, and pointed pliers. They are composed of pointed tips, knife edges and pliers handles. They are generally made of 45# steel. They are used to cut single and multi-strand wires with thinner diameters and to give orders. Stranded wire joint bending, stripping of plastic insulation layer, etc., can be operated in a relatively small working space.
5. Curved nose pliers
Also called elbow pliers, its function is similar to that of needle-nose pliers without cutting edge, and it is suitable for use in narrow or recessed working spaces.
6. Flat nose pliers
It is a commonly used tool for assembly of metal parts and telecommunications engineering. It is generally used to bend metal sheets and metal filaments to make them into the required shape. In repair work, they are used to install and pull out pins, springs, etc.
7. Diagonal pliers
Mainly used to cut metal wires, flat-nose diagonal pliers are suitable for use in recessed working spaces.
8. Top cutting pliers
End-cutting pliers are similar to diagonal pliers. They are mainly used for cutting steel wires with the cutting edge at the top.
9. Water Pump pliers
The function is similar to a pipe wrench, but it is lighter, smaller and easier to use than a pipe wrench. However, the clamping force is not as good as a pipe wrench. Generally, it is only suitable for household non-professional emergency or simple installation of water pipes.
10. Slip joint pliers
The shape resembles a carp. The opening width of the jaws has two adjustment positions, which can be enlarged or reduced. It is mainly used to clamp round parts. It can also replace small nuts and small bolts with a wrench. It is often used in the auto repair industry.
11. Circlip pliers
Commonly known as circlip pliers, it is a special tool used to install inner and outer circlips, and can also be used to remove circlips. .
12. Vigorous pliers
It is mainly used for clamping parts for riveting, welding, grinding, etc. It can also be used as a wrench. Its characteristic is that the jaws can be locked and generate a large clamping force to prevent the clamped parts from loosening.
