智婆与愚公，告别夏天的劳顿

智婆与愚公，告别夏天的劳顿

 

我用我的手和我的小锄头除杂草。

智婆：你干这个浪费时间，用除草剂几秒就可全把宽叶草（broadleaf）杀光。

愚公：我不想用植物生长刺激素2，4-D伤害人，动物以及环境,。我用任何东西前都查看它的说明。不要人云亦云。

 

2，4-D是除宽叶草（dandelions, clover, and thistles）除草剂里的主要成分，

下面的英文是google search的有关2，4-D的结果：

The main function of 2,4-D is to act as a selective herbicide to kill broadleaf weeds, such as dandelions, clover, and thistles. It works by disrupting the way certain plant cells grow. It is widely used in agriculture, on lawns, in forestry, and for managing infrastructure rights-of-way. 

 

How it works

• Selective control: 2,4-D kills broadleaf plants (dicots) but does not harm grasses (monocots), which is why it's used on both lawns and some crops like corn.
• Cellular disruption: It interferes with a plant's growth processes by mimicking a natural plant hormone, causing it to grow uncontrollably and ultimately die.
• Various forms: It is available in different chemical forms, such as salts, esters, and an acid form, which affect its properties and how it behaves in the environment. 

 

Where it's used

• Agriculture: Used on a variety of crops to control weeds that would otherwise compete for nutrients and water.
• Lawns and turf: A common active ingredient in commercial weed-and-feed products for residential and commercial lawns.
• Forestry and range land: Used to manage forests and control weeds in pastures.
• Aquatic sites: Applied to control weeds in surface waters, with restrictions on swimming for a period after application to avoid eye irritation.
• Infrastructure: Used along roadsides and other rights-of-way to keep vegetation from obstructing visibility or services. 

 

2,4-D is a selective herbicide that kills broadleaf weeds by mimicking plant hormones, and it can be harmful to humans and animals, especially with high or prolonged exposure. Potential harms include endocrine disruption, which can interfere with hormones, and links to an increased risk of certain cancers like lymphoma. While often considered moderately toxic to birds, it can be highly toxic to fish, particularly certain ester forms, notes National Pesticide Information Center.
