Question

what is chemical control

Answer 1

Chemical control is the uses of toxic chemical to control insects, diseases and weeds.Chemical control is based on substances that are toxic (poisonous) to the pests involved. When chemical pesticides are applied to protect plants from pests, diseases or overgrowth by weeds, we speak of plant protection products.

Answer 2

Although the use of chemicals is not always essential, herbicides can be an important and effective component of any weed control program.

In some situations herbicides offer the only practical, cost-effective and selective method of managing certain weeds. Because herbicides reduce the need for cultivation, they can prevent soil erosion and water loss, and are widely used in conservation farming.

In some cases, a weed is only susceptible to one specific herbicide and it is important to use the correct product and application rate for control of that particular weed. Common mistakes include incorrect identification of the weed or using inappropriate products.

In most cases, weeds must be actively growing to be vulnerable to herbicide treatments.

Herbicide resistance can also be an issue with some species.

Conditions such as wind speed and direction, the possibility of rain and proximity to waterways should also be taken into account when preparing to use herbicides.
