[QUOTE="Feldspar, post: 5672158, member: 386"] Been out walking middle drilled block of wheat. Annoying amount of black-grass come through and brome. For all we talk about black-grass, I have spent more time worrying about brome over the last few years than black-grass. But I digress. Some of the these two leaf BG are clearly being affected by the pre-em, but I'm confident that enough of them will be left to need Pacifica. We have enough brome to justify by itself and if done in the spring there will be some wild oats which will help justify the application if we wait that long. There seems to be a clear trade-off here. Pacifca now on small plants which are being affected by the pre-em, or in the spring on much larger plants (will have to wait a while for temperatures to rise to get decent brome control) which will have got over the pre-em. NIAB results show better black-grass control in the autumn than in the winter, and I think Bayer's results are similar (?). To me that indicates that it might be better to take the disadvantage of the stressed plants not taking as much chem up rather than the disadvantage of applying to much bigger plants that are tillering fast. Thoughts? Also, who reckons it's still warm enough for Pacifica? [/QUOTE]
