In 1967, the United States registered an herbicide called dicamba that was developed by the German chemical company BASF (EPA, 2009, p. 18). Its intended use was to control post-emergent broadleaf weeds and woody plants. Since then, 434 dicamba products have been developed to control weeds in a variety of settings and dicamba is currently the seventh most commonly used herbicide in the U.S.
5) Salt can use as a weed killer because the salt itself can cause the plant to dehydrate through osmosis. Since the salt has a higher concentration, it will cause the plants water molecules and nutrients to be absorbed by the salt, leaving the plant all
Noxious weeds can be very harmful to all aspect of rangeland. They can outcompete native grasses and forbs causing a loss of forage to livestock and wildlife. A large number of noxious weeds have been purposely introduced to the United States for purposes such as food, forage, fiber and decorative ground cover. Programs have been created to help with the invasion of weeds. It’s taken lots of time and resources to get programs started up to be able to combat the effect of noxious weeds.

The threat of super weeds is very real. The most common herbicide used, glyphosate, is also used in the common weed killer Round-Up. This means that if these superweeds get in our front yards, they are going to be very difficult to remove. Over 62.2 million acres of farmland are already infested with these herbicide resistant weeds. Nevertheless,
There are not many workers to cut acres full weeds to make the farm look organized. So to fix the solution, farmers use chemicals to kill the weeds. This solution makes it easier for the farmers to use because the process is fast. Another problem is that there are pest such as rats, birds, and other creatures that ruins farmers product. Pest tends to enter the farm and eat the products and will come back for more. Pest can also enter the farm and ruin the farm. Killing or removing the pest is the only way to fix the solution. But removing one by one is difficult. Using chemical to remove all the pest is the best way. Same method goes to removing all the insects and bugs. Insects and bugs are feeding on vegetables and fruits. Insect and bugs can ruin vegetable and fruits because when they are feeding on the product they tend to ruin the quality of the product.

As a homeowner with a beautiful yard, the last thing you want to have to deal with is a yard with weeds in it. In order to effectively deal with this problem, you can try these weed-killing methods.
Companies and researchers alternate the genetic structure of crops to withstand pesticides, non-GM weeds and insects can gradually develop a resistance to the chemicals. At this point farmers actually have to increase their use of pesticides. These practice causes weed populations to adapt to the herbicide and eventually become resistant to it. Once these superweeds emerge farmers must find a new herbicides and more potent products.
However, pesticides are used to control pests, which include insects, mice and other animals, unwanted plants (weeds), fungi, or microorganisms like bacteria and viruses. Often misunderstood to refer only to the insecticides, the term pesticide also applies to herbicides (that control weeds), fungicides (that control fungi), and substances used to control other pests. In addition, because many pests tend to travel between farms, resistance to pesticides can evolve at an inefficient rate. Farmers can increase the economic efficiency of chemical use by adapting integrated pest and resistance management practices, such as rotating crops and pesticides, reducing reliance on a single pesticide, adjusting planting and harvesting dates, scouting fields, and using more benign, and biological control

If I had lived during the Holocaust, the hardships would include lack of shelter, starvation, and survival. To start, people struggled to find a safe shelter. The book Milkweed is about a boy who has to change the locations of his shelter to be able to survive. I know that during this time period a lot of people who were jewish were taken to concentration camps were they were forced to work and were treated harshly. Because of this people had to change the location of their shelter to escape getting caught. Additionally, people also had to face the struggles of starvation.
