Notes:
A series of eleven field experiments over two seasons investigated the control of Galium aparine (cleavers) with mecoprop and a proprietary mixture of ioxynil plus bromoxynil. Applications of mecoprop (2⋅4 kg a.e. ha−1) between December and March gave variable results but a mixture of ioxynil + bromoxynil (0⋅6 kg a.i. ha−1) and mecoprop improved control up to at least 90%, at most sites. Applications of mecoprop alone in April were most effective and frequently achieved more than 90% control. In May, when the G. aparine plants were very large, it was less successful. The reasons for the environmental effects on performance are discussed. Preliminary examination of the effect of soil temperature on mecoprop activity indicates that the reliability of control increases with increasing temperature (0–12°C). An average of 94% control was achieved when soil temperatures were greater than 6°C.
