Choosing a grass reseeding mix can be tricky. Even so, the phrase "No, surely its simple" is one I often hear, as well as assumptions that "one field of green is the same as the next." However, with the quality and diversity of work carried out by plant breeders over the last 70 years or so, each field really is different in terms of output.

I think we'd all agree last year was a challenging one, with the lowest amount of rainfall ever recorded since records began. When we look at the results from last season's maize harvest, it's important to understand the notable weather patterns we saw and the effects they had.

There are many reasons to sow new grass leys, but none more prominent than having some in poor condition following the wettest winter on record and one of the hardest spring droughts.

The recent rainfall will help things but it cannot reverse the damage that's already been done. Unfortunately, many leys have lost key elements, allowing weed grasses such as annual meadow grass, rough stalked meadow grass and couch grass to populate the thinner areas. 

The relentless wet weather is likely to mean that more growers will be growing maize this season; either for the first time, or for the first time in a long time. Maize is a crop that needs careful management and seed treatments are an important part of that management that have seen some significant changes.

Most maize growers will be aware of the challenges we now face with the loss of the active ingredient methiocarb; best known as the seed treatment Mesurol. This seed treatment has for years provided class leading bird repellence, particularly against rook damage and other corvids, to the extent that some will have forgotten quite how damaging these pests can be.
