Acetochlor is also a herbicide, but many people don't know much about it. It is even stranger. Acetochlor is one of the most used herbicides in China. Let's take a look at the small series of pesticide nets . Let's go.
In fact, acetochlor is not a special pesticide that has only recently emerged. It was developed in 1971 by Monsanto (this article is no matter what else). To date, this pesticide has been used for more than 40 years. Of course, this pesticide is not for insecticide, fungicidal, but for the presence of weeds, which is what we call herbicides.
Since it is a herbicide, why not kill strawberries? Isn't strawberry a grass? The reason is very simple. Acetochlor is highly inhibitory against certain kinds of grasses, such as Tang, foxtail, and tendon. Troubled plants in the fields of sedge, thousand gold, maiden, wild oats, bluegrass, hard grass, teff, etc. The principle of action is that when the grass absorbs acetochlor through the coleoptile, it will affect the normal growth of the plant. Acetochlor is usually used as a soil treatment agent, that is, it is sprayed onto the soil surface before and after sowing to suppress weed germination.
Therefore, acetochlor is widely used in the weeding work of crop fields such as corn, cotton, beans, peanuts, potatoes, rapeseed, garlic, tobacco, sunflower, ramie, and green onions. The herbicide in the strawberry field is not the main work of acetochlor. In this news, acetochlor is detected, which can be said to be somewhat embarrassing.
These are not critical. What everyone cares about is how people will eat and how will they affect their health?
We saw in the CCTV financial news that acetochlor was detected in 8 strawberry samples, the highest detected is 7 times the EU standard, reaching 0.367 mg / kg, and this thing is still B-2 Carcinogens, it sounds like strawberry can't eat. Is this the case?
It is not surprising that all samples have acetochlor. After all, acetochlor is a heavily used herbicide . The problem is that we start using herbicides in the production of strawberries, which is worth noting. Weeding is one of the basic tasks of growing crops. It used to be weeded with hoes at noon, and now it has become chemical weeding. The most exaggerated one I have ever seen is that a young farmer wants to open the wasteland on the edge of the field. It is not a mowing but a direct spraying of herbicides (not acetochlor)! The abuse of herbicides is indeed a problem.
The heavy use of herbicides will inevitably bring environmental and health problems, especially the long-term degradation of herbicides. The half-life (half-degradation) in river water can be as long as 131 days, and the half-life in seawater can reach 193 days! It is said that the herbicides used now continue to affect our environment for a long time to come. At present, acetochlor is one of the three most easily detected herbicides in natural waters. Moreover, this herbicide also affects the development of fish.
