Question

Disadvantages of weeds any 6 points

Answer 1

Answer:

Unintentional Unintentional Spread

The spray application of weed killer often makes it difficult to control. While aiming at the unwanted plant, the herbicide can splatter onto nearby plants that you want to keep. On windy days, the spray drifts and may land on your garden and landscape plants. High temperatures and dry conditions often cause the spray to turn into a gas and travel to other areas. Using a nonselective herbicide under poor conditions often causes other plants to die and may damage trees and shrubs in your yard.

Health and Environmental Impact

The chemicals used in weed killers cause damage to the environment and to the health of people who come into contact with them. Inhaling or swallowing an herbicide may cause illness or even death, depending on the amount, type of chemical and age of the person. Chemicals that drift out of your yard may travel to other areas and hurt wildlife or plants. The chemicals can wash away into nearby waterways or travel down into the groundwater supply. The weed killer may damage the environment and enter the human food chain and water supply.
