Pre- and post-emergence herbicide screening for weed control in quinoa (Chenopodium quinoa): field trial

Output: Bijdrage voor congresCongres - Meeting abstract


Both farmers and consumers are interested in alternative crops that can give a higher economic and nutritional value. The multidisciplinary research project at University College of Ghent ALTERGRAIN studies a selection of alternative and pseudocereals through a whole chain approach which is deployed in the field and processing phase, the nutritional aspects before and after processing into derived foods and the economic potential of these crops for the Flanders’s region.
Due to our moderate climate with regular rainfall weed control is an important issue especially controlling the weeds Chenopodium album in the crop quinoa (Chenopodium quinoa). Following a 2-year herbicide screening in pots, a field trial was set up at the Experimental farm in Bottelare (University College of Ghent – Ghent University) to determine the selectivity of several combinations with selected pre- and post-emergence herbicides. The pre- and post-emergent tolerance of the quinoa crop was evaluated to respectively 25 combinations of active ingredients with 4 replications. Plants were evaluated for emergence density, phytotoxic effects on plant growth, weed determination and raw yield measurement. Field net plot size was 7,5 m² and all plots were machine-sown and combine-harvested.
The results give interesting information regarding herbicide tolerance for the crop studied on the field. Based on these results an application for authorization of herbicides can be submitted for the crop quinoa.
