Growers wanted data on whether there are any differences in fungicide efficacy due to application.
Ultra-high pressure (UHP) injection of fungicide was used to improve fungicide efficacy on rhizoctonia in wheat.
In the field
The concept was designed in conjunction with SARDI with its researchers reporting increased efficacy on rhizoctonia with fungicide placement below the seed bed in previous years.
The trial was sown by Andrew Bird, SANTFA, and Greg Butler, SANTFA, using a Serafin Ulti-sow single disc seeder and a FLOW 55psi UHP Pump and injection nozzle.
UHP injection of fungicide for rhizoctonia control in wheat did not reduce lesions on seminal or on crown roots compared with a seed dressing treatment of fungicide. UHP injection did not improve wheat yields and there was a marginal but insignificant reduction in wheat yield observed from the UHP application method compared to the fungicide seed treatment.
