8 points difference between imidacloprid and chlorpyrifos

Imidacloprid is a high-efficiency insecticide of nicotine. It has broad-spectrum, high-efficiency, low toxicity and low residue. After the pests are exposed to the agent, the normal conduction of the central nervous system is blocked, causing paralysis. Chlorpyrifos is an organophosphate insecticide, which is highly effective and broad-spectrum. It is one of the main varieties to replace high-toxic organophosphorus pesticides. So what are the differences between imidacloprid and chlorpyrifos as high-efficiency insecticides in seed dressing? Please see below for details:

What are the differences between imidacloprid and chlorpyrifos in dressing?

1, after seed dressing

Imidacloprid: The seeds are smooth and easy to sow.

Chlorpyrifos: The seed has strong adhesion and rough surface, which is not conducive to sowing.

2, insecticidal mechanism

Imidacloprid: withdrawal, stomach toxicity.

Chlorpyrifos: contact killing, stomach poisoning.

3. Effective period

Imidacloprid: 210 days.

Chlorpyrifos: 120 days.

4, security

Imidacloprid: high (nicotine).

Chlorpyrifos: poor (organophosphorus).

5, applicability

Imidacloprid: broad spectrum (multiple crops can be used).

Chlorpyrifos: peanuts, corn.

6, smell

Imidacloprid: not odorous.

Chlorpyrifos: stimulates the taste.

7, insecticidal spectrum

Imidacloprid: underground pests, aphids.

Chlorpyrifos: broad spectrum of insecticides, seed dressing is mainly underground pests.

8, regional

Imidacloprid: Suitable for all areas.

Chlorpyrifos: Local area is invalid.

With the economic development, the popularization of traffic lights has made the roads more and more orderly. We can see different types of traffic lights on the highway when we walk and drive. There are red and green traffic lights, red, yellow and green. Traffic lights, pedestrian lights, pedestrian countdown lights, arrow traffic lights, bicycle traffic lights, countdown traffic lights, etc. The current penetration rate of traffic lights in cities is over 80%. Do you know the purpose and composition of traffic lights?
1. When the green light is on, vehicles can pass, but turning vehicles shall not hinder the passing of straight vehicles and pedestrians.
2. When the yellow light is on, vehicles that have crossed the stop line can continue to pass; other vehicles are waiting to pass. Or observe the left and right and pass under safe conditions.
3. When the red light is on, vehicles are prohibited.
4. At intersections where non-motor vehicle signal lights and crosswalk signal lights are not installed, non-motor vehicles and pedestrians should pass according to the signs of motor vehicle signal lights. follow traffic rules.
5. At some marked intersections, when the red light is on, vehicles turning right can pass without obstructing the passage of vehicles and pedestrians.
6. Traffic signals can make vehicles run in an orderly manner, reduce traffic congestion, and reduce traffic accidents, so that all traffic participants can drive in an orderly manner, avoiding the time waste caused by traffic congestion and the life and property caused by traffic accidents. loss.
The composition of traffic lights: traffic lights are composed of red, green, and yellow lights.
Types of traffic lights: Traffic lights are divided into motor vehicle lights, non-motor vehicle lights, crosswalk lights, lane lights, direction indicator lights, flashing warning lights, road and railway intersection lights.
Traffic accidents that do not follow the directions of traffic lights and run red lights are repeated. The root cause of these problems may be related to childhood education and traffic safety awareness. Because the road traffic signal signs in counties and towns have not been widely popularized, or because there are few road vehicles in towns, people running red lights and becoming a habit, so how to avoid these problems, we need to grasp the root of the problem. Improve people's awareness of traffic safety and strengthen the learning of traffic safety knowledge.
