摘要: SA¸nderskov M, Swanton CJ & Kudsk P (2012). Influence of nitrogen rate on the efficacy herbicides with different modes action. Weed Research 52, 169–177. SUMMARY: Outdoor pot experiments and field were conducted to examine influence herbicide efficacy. Growth unsprayed Tripleurospermum inodorum increased increasing in experiments; also susceptibility tribenuron‐methyl. An at high was observed for Anagallis arvensis, but contrast T. inodorum, growth A. arvensis unaffected by rate. Chenopodium album promoted supply. However, no evident C. album tribenuron‐methyl or ioxynil+bromoxynil experiments. Field natural populations spring barley grown rates showed similar results. In conclusion, affected some not all combinations weed species herbicide. Decreased only very low rates. The results suggest that effect will be marginal intensive farming systems supply, intensity systems, patchiness might increase.
