[QUOTE="yellow belly, post: 1788336, member: 305"] spring crops are not the answer to bg with one field on one farm but they can be the answer depending on when the spring crop is planted and which spring crop is grown in my experience on heavy land which does not suffer from drought to control bg the spring crop must not be planted too early 1 april is a good date but the 15 is better even using avadex and other preems even later may not control the bg as some seed will germinate in may and june if it is given enough water and space imho spring wheat will be the worst spring crop as it is planted too early and has a lot of n used to grow it mid april spring beans or may planted linseed are much better bg needs nitrogen for prolific seed production so any crop with low nitrogen application reduce seed return if I use spring cereals for bg then they are a first cereal two consecutive cereal crops will just make bg worse if you have wall to wall bg in a crop it will take more than 2 year to eliminate it the experts underestimate the effect that notill has on improving the effects of residual herbicides kerb gives very good control with no till or autocast mostly above 98% which eliminates bg from the low bg fields if you have a high enough rape plant establishment low rape seed rates are only for bg free fields [/QUOTE]
