STABILITY OF VEGETATION-APPLIED HERBICIDES AND THEIR MIXTURES WITH COMPLEX FOLIAR FERTILIZER LACTOFOL B AT OIL-BEARING SUNFLOWER BY INFLUENCE OF DIFFERENT METEOROLOGICAL CONDITIONS
Published: 1 Jun 2014
Abstract: During the period 2010 - 2012, on the experimental field of the Field Crops Institute - Chirpan was carried out a field experiment with oil-bearing sunflower (Helianthus annuus L.). It was investigated 18 variants from the three technologies for oil-bearing sunflower growing - conventional (hybrid Arena), ClearField (hybrid Alego) and ExpressSun (hybrid P64LE20). Treatment of complex foliar fertilizer Lactofol B with herbicides Stomp, Raft, Wing and Modown as tank mixtures after soil-applied herbicide Pelican increases the selectivity of these herbicides. The effect of foliar fertilizer Lactofol B is the poorest by combination with herbicides Goal and Pledge. From the viewpoint of conventional technology for growing of oil-bearing sunflower, high rating have tank mixtures of herbicides Wing, Raft, Stomp and Modown with complex foliar fertilizer Lactofol B, followed by tank mixtures of Goal and Pledge with Lactofol B. Technologically the most valuable are herbicide tank mixtures Express + Stratos ultra and Pulsar + Stomp by respectively ExpressSun and ClearField technologies. Herbicides Goal, Stomp, Raft, Wing, Pledge and Modown by self-use without foliar fertilizer Lactofol B is more appropriate to be used as soil-applied herbicides.
