Soils
Potato is the world's fourth largest food crop, being cropped in 140 countries on an area of 19 million hectares, with a total annual production of 322 million tons and an average production of 40 tons per hectare. Perennial dicotyledonous weeds represent a real danger to potato culture because they cannot be controlled after the potato has emerged. Such weeds are: Canadian thistle (Cirsium arvense), field bindweed (Convolvulus arvensis ) and hoary cress (Cardaria draba). Herbicides that are applied upon the soil or in early preemergence do not control these weeds because they have vigorous underground organs that can pass through any applied herbicide on the soil. In order to control these weeds we have organized an experiment with several treatments of herbicides applied upon the soil and on vegetation, as follows: V1 - Stomp 330 CE 5 l/ha, V2 - Dual 960 CE 1.2 l/ha + Goal 4F 1l/ha + Roundup 4 l/ha as preemergent treatment against perennial broadleaves weeds spots + Killer Super 5 EC against grass weeds on post-emergence, V3 - Surdone 0,8 kg/ha, V4 ? no herbicide. The best results have been given by V2 treatment, where perennial weeds were radically controlled on preemergence and post-emergence.
