CPM Research Briefing - Cereal PGR in-depth
Tom Allen-Stevens, Editor of leading arable technical magazine, CPM, has investigated the latest research on PGR use in cereals, and how that can help growers manage crops more effectively this spring. Read his report here:

Key research findings in Tom's report include:
- Faster uptake of Moddus in cold conditions
- Stronger rooting encourged by early T0 applications
- Moddus formulation enhances uptake and performance, compared to generic PGRs
- On-farm practice sees biggest benefit from early start to split dose programmes
In the article, James Southgate of Syngenta highlighted research into PGR application and leaf uptake at tempertures of 7°C - typical of conditions at the T0 timing.
“The results are pretty clear. After just 15 hours, 70% of the Moddus had been taken up by the treated plants, while it took 55hrs for the same uptake of chlormequat," he said.
"In a prolonged period of cold weather, common at that time of year, you’d want the PGR to be taken up and to start working as early as possible. What’s more, if the product’s hanging around on the leaf surface, it’s more prone to being washed off in a rain shower.”
"That's why Moddus should be the first choice at T0 PGR timing," James advised.
"If you are going to use chlormequat, keep that for the T1 timing and adjust the rate in combination with Moddus then, according to lodging risk."
