A long fallow after corn was the previous field history prior to planting the crop in early October 2017. This was one of the factors that helped the trial area to achieve what it did during the season.
The crop suffered quite severe thrips damage soon after emergence and this set the crop back in the areas closest to a wheat field. The plant stand didnメt not seem to be affected, only the growth of early true leaves. Once the thrips were controlled the crop really took off and continued well until severe phenoxy damage showed up in late December, early January. Symptoms of the drift event were present right through the rest of the season and all new growth was affected.
The trial field was looked after very well and variable rate mepiquat chloride was applied to help control excess growth. Defoliation occurred 182 days after planting. The long and warm finish to the season helped it achieve what it did. The highest yielding variety was Sicot 714 B3F at 12.88 b/h. This was closely followed by Sicot 707 B3F. These two varieties finished earlier than the other Sicot 74 family lines and were ready for defoliation up to 10 days earlier grown side by side
