There has been a spate of reported sprayer problems from applications of T2 sprays with new fungicide Univoq (active ingredient Inatreq) reportedly damaging rubber o-rings and nozzle diaphragms.

The issue seems to be sporadic, with many operators reporting they've had no problems. 

Guidance has been issued by Corteva to increase volume to 200 l/ha and to reduce tank mixes with other products.
