How is mechanical method of controlling weeds different from biological method?

Mechanical
Mechanical weed control refers to any technique that involves the use of farm equipment to control weeds. The two mechanical control techniques most often used are tillage and mowing.
Biological
Biological weed control refers to any technique that involves the use of natural enemies of weed plants to control the germination of weed seeds or the spread of established plants. This is a rapidly expanding area of weed control with many examples. Examples of biological weed control include sheep to control tansy ragwort or leafy spurge, cinnabar moth and the tansy flea beetle to control tansy ragwort, the chrysolira beetle to control St. John’s Wort, and the use of goats to control brush on rangeland.

I think biological is the best ,in this method , weedicides are used to kill the weeds, weeds are the plants which grow into another crop, weeds are very harmful for another plant as they take all the nutrients and sunlight. so they are called as unwanted plants, and to remove them we use weedicides by mechanical or biological method…
in biological method , the man power is used .
in mechanical methods, it reduces man power and works technically….
I hope it will help you a lot….

Mechanical method– Involves pulling out weeds with hands or by ploughing. Weeds can also be removed using a big comb-like harrow or using a trowel. Biological method: involves the deliberate use of insects or some other organisms which consume and specifically destroy weed plants
