The gates are now metaphorically closed on all cereal fields, and will not open again before harvest unless glyphosate is required to speed up and even the ripening process.

With very few new chemicals arriving on the market, coupled with the steady withdrawal of several useful products, you could be forgiven for assuming that the agronomy of winter and spring cereal must have stagnated. In fact, techniques are constantly being finetuned and refined; nothing ever stays the same in farming for too long.
