Question

discuss the negative consequences of chemical control of weeds on rangelands

Answer 1

Weed control chemicals are often sprayable, making it simpler to penetrate unwanted plant leaves and roots. However, if you do not spray precisely, chemicals will drift into the surrounding area. Non-targeted plants may die or suffer serious harm from exposure, depending on the chemical. Avoid applying on windy days. Additionally, use on a moderate day to avoid chemical vaporization. When temperatures rise over 85 degrees Fahrenheit, chemicals tend to disperse swiftly into the surrounding air mass as they expand away from the target site.

Many chemical compounds cover plants in a layer that decomposes weeds slowly. However, if a downpour happens shortly after application, the chemical coating filters into the soil below. Water runoff introduces hazardous pollutants into local water sources, ranging from lakes to streams. Contaminated water sources harm plants, humans, and animals alike. A similar water runoff pattern happens when chemical treatments are applied directly to soils to inhibit weed seed germination. Apply your weed control chemical during a dry season. Excessive watering in your garden should be avoided until the chemicals are clearly degrading the targeted weeds.

Toxins may be absorbed by fish and birds that consume certain fish species as chemicals pollute groundwater. Chemical drift in the air also damages helpful insects like bees, which help with pollination and high fruit production. Adjust your spray nozzle to generate bigger droplets to minimize chemical drift that affects beneficial species. To maintain the big droplets on the targeted spot, spray close to the problematic plant. Fine sprays are easily collected by breezes and damage the creatures around them.
