Experiences in the economic use of herbicides tolerant crops

Experiences of the economic viability of herbicide tolerant crops (HT crops) were collected in a literature review from countries in which commercial cultivation is taking place. The results show that HT crops do not generally produce increased yields and no herbicide savings are effected in the long term. Economic benefits may be derived from the no-tillage system thereby made possible and from the simplification of chemical weed control. A direct transfer of results is only possible up to a point because of different structures and price levels in Switzerland. The cost and expense of coexistence measures were not included.
