THE PLACE OF HERBICIDES AND NON-CULTIVATIONS IN THE PRODUCTION OF VEGETABLES FOR PROCESSING
Evidence is presented to show that carrots, red beet, peas and Brussels sprouts, all of which are potentially suitable for processing, can be grown without post-sowing or post-planting cultivations where chemical weed control is practiced. There is evidence to indicate that where these crops are dependent on soil-cultivations for weed control, yield can be reduced. Satisfactory results with respect to crop safety and weed control can, however, only be achieved by correct timing of the herbicide treatments in relation to the growth of the crop and weeds. Trials have shown that persistent soil-acting herbicides are suitable for weed control in many crops and that their residual effects suggests that they can be used safely in short-term crop rotations if care is taken in the choice of crop and the timing of sowing or planting after a herbicide application.
