Answer:
There are three main ways of avoiding the spreading of an invasive plant species via manual control. Manual control techniques include activities such as hand-pulling, digging, flooding, mulching, burning, removal of alternate hosts and manual destruction or removal of nests, egg masses or other life stages. These techniques work best on small populations or in areas where chemicals or motorized equipment cannot be used. Manual control efforts must be persistent and several treatments may be needed to reduce or eliminate the target population. If infestations are too pervasive, manual control may become labor intensive and thus not economically feasible. Digging/Hand-pulling: Remove entire root to prevent resprouting. Usually works best with small or young plants, in sandy or loose soils, or when soils are damp. Smothering: Use mulch, black plastic, carpet, or any other impenetrable barrier to cover target plants for at least one growing season. The effectiveness of this technique can be increased by first cutting the target plants and then smothering them. If dealing with a species that produces clones, be sure to cover all stems of the species. Flooding: This is only feasible where water levels can be manipulated to completely cover cut plants for a period of time. The depth of water necessary and the amount of time cut plants should be covered will vary from species to species.

Answer:
Both provides help in diagnosing and solving the health problems.
Explanation:
The main advantages of public health approach is that it can help us in measuring the problem, determining the cause for the problem, determining how to prevent or ameliorate the problem, and implementing effective strategies on a larger scale and evaluating the impact while on the other hand, medical approach provides explanations of mental ill-health that many people who experience mental health problems as well as diagnosing and naming conditions can help to reassure people that what they experience is 'real' or not.
