Effect of some soil herbicides on the vegetative habits of walnut seedlings (Juglans regia L.)

Abstract

 The effect of the soil herbicides napropamid, pendimethalin, terbacil, metolachlore, linuron, oxyfluorofen, oxadiargyl and isoxaflutol on the vegetative habits of walnut seedlings, cv. Kuklenski was studied in a model pot experiment under controlled conditions.

The depressing effect on seedling development expressed in growth suppression and significant decrease of the aboveground plant mass was established after treatment with pendimethalin – Stomp 33 EC - 400 ml/da, metolachlore – Dual gold 960 EC - 150 ml/da and oxyfluorofen – Galigan 240 ЕC – 200 ml /da.

When applying napropamid – Devrinol 4 F – 400 ml/da, terbacil – Sinbar – 80 WP – 100 g/da, linuron – Afalon 45 SC – 300 ml/da and isoxaflutol – Merlin 750 WG – 5 g/da phytotoxicity expressed in suppressing the vegetative habits was not established in walnut seedlings.
