From the beginning (in the 60 of last century) the focus of IPM was the pest, disease and weed management in the agroecosystems. The concept evolution leads to include all other aspects of crop management essencial to do an agriculture crop, like irrigation, nutrition, soil conservation and so on. In the last case we call it ICM (integrated crop management). The focus moved on from pest control to farm optimization.
The use of high level of management in agroecosystems could be done excluding all the human made pesticide and fertilizers sprayed over crops or soil incorporated. This is the case of Organic Farming systems. In our case in Europe we exclude the contact of all synthetic human made chemicals with the crops when farmers produce under this label. In the situation subventions are necessary to compensate the farmers from the loss of income.
