A Bordeaux mixture of copper sulfate and lime kills fungal pests on grapes and melons. Carbaryl or Malathion kills insect pests by causing nerve damage and disrupting life sustaining nerve impulses. Metaldehyde kills slugs and snails in the same way.
It always is important to read labels and follow proper procedures and instructions when mixing, applying and storing chemicals. Specifically, some chemicals are more indiscriminate, long lasting, powerful or toxic than others. For example, metaldehyde effectively stops slug and snail damage to edibles. But there must be no contact between it and children or domestic animals.
Glyphosate, 2,4-D, and dicamba are commonly used chemicals to kill weeds. These herbicides work by disrupting the growth and development of weeds, causing them to die. It is important to carefully follow the instructions on the product label and consider the environmental impact when using these chemicals.
Hot water can effectively kill weeds by pouring it directly onto the weeds, which causes the plant cells to burst and die. This method is a non-toxic and environmentally friendly way to control weeds without using chemicals.

The chemicals to be applied and the forms to be used depend upon whether the water body involves limited-flow waterways, large impoundments or static water. Professional landscapers often recommend copper chelates or sulfates for controlling algal weeds, diquat or fluridone for controlling such submersed plants as free-floaters and pond weeds, and glyphosate for emergents such as cattails and rooted floaters such as water lilies.
Roundup is the name of a herbicide used by farmers to kill weeds. A plant is said to be roundup ready if it is resistant to roundup, so that you can spray a field with roundup and it will kill the weeds but won't kill the roundup ready crop.
Miracle-Gro is a fertilizer and not specifically designed to kill weeds. However, if not used properly, it can promote the growth of weeds along with desired plants. To kill weeds, a weed killer specifically designed for that purpose should be used.
