Abstract:

In our experiments the effect of three preemergent herbicides was examined on potato varieties. The experiments were carried out under greenhouse conditions in pots with six Hungarian potato varieties. The following herbicides were applied: PATORAN 50 WP (metobromuron), SENCOR 70 WG (metribuzin) and COMMAND 48 EC (chlomazon). The results indicate that the variety Góliát showed the slowest growth. In the case of Lilla fresh and dry shoot weight was decreased by the application of PATORAN 50 WP and SENCOR 70 WG. Tuber weight showed a decrease with the application of SENCOR 70 WG in all varieties. The least tuber weight appeared with the varieties Kánkán and Szózszorszép. Nutrient concentration of potato and N, P and K uptake by potato were examined. In the case of White Lady, Százszorszép and Kánkán N concentration and uptake increase significantly because of SENCOR 70 WG. There was a significant increase in phosphorus concentration and uptake in White Lady, Hópehely and Kánkán varieties in all herbicide treatments. Potassium concentration increased in the case of all the six varieties because of herbicide treatments. Based on these experiments all varieties showed susceptibility against the used herbicides. The results show that important differences occur in the sensitivity and tolerance of varieties against herbicides, which are consequently significant for practical crop protection.
