PP333 spray boosts ryegrass yield and reduces lodging and shattering.
Spraying PP333 on annual ryegrass before jointing can reduce plant height, increase dry matter accumulation, and improve seed yield. Higher concentrations of PP333 lead to shorter plants but can also decrease dry matter accumulation. PP333 has the most impact on spike number, which is crucial for seed production. It can also reduce lodging and shattering of the plants, with a stronger effect at higher concentrations.
