Amaranth is receiving increasing attention as an alternative crop to small grain cereals. From a weed control point of view cultivation of amaranth poses two problems. Firstly, amaranth grows slowly after emergence and hence is very susceptible to competition by weeds and secondly, seed losses at harvest are significant due to an uneven maturing and volunteer amaranth plants could potentially become a weed problem in following crops. Nonetheless, no studies are available on the tolerance of amaranth to herbicides or the survival of seeds in the soil. In this study we examined 1) the tolerance of amaranth to a range of herbicides in a series of outdoor pot experiments and in one field experiment and 2) the survival of amaranth seeds buried at 4 depths (2.5, 5, 10 and 25 cm) in 3 countries. The results showed that amaranth is very susceptible to broadleaved weed herbicides. Of the broadleaved herbicides examined only clomazone, clopyralid, phenmedipham and triflusulfuron were tolerated by amaranth. Applying clomazone early post-emergent instead of pre-emergent provided full crop tolerance even at the highest doses (P |
